Do all 4 ram sticks need to be the same reddit. On Ryzen 7000 having 4 sticks kills the performance.

Do all 4 ram sticks need to be the same reddit How does it end up in performance? My laptop has 8gb (2 sticks of 4gb) of ram but i'm going to upgrade it by replacing one of the 4gb sticks with a 16gb stick, is this ok to do? I've seen different brands with different sizes all mixed together. [EDIT: NOT A SINGLE WAY OF SOLVING THIS PROBLEM CAME UP. It will run at the slower so it more cost effective when buying more ram to match. Only use 4 sticks if you are sure your board can handle 4 sticks since not all boards with 4 dimm slots can stably run 4 sticks all at the same time at a specified speed. You'll need to find out what the ram memory is made by (thaiphoon burner) and then find the safe voltages for operation (varies between different sticks) and then work on tuning the mhz values up and then tightening the timings all while staying stable. On channel A run 4+4 sticks and on channel B run 2+2 sticks. The problem I'm having is the system will not POST when all 4 RAM sticks are installed. 2. It's not guaranteed that 8gb ram sticks are single rank, but in my personal experience, a lot of 8gb sticks of ram are single rank. It is measured and factory matched to insure operation Apr 7, 2018 · While matched memory is generally recommended, as long as you buy another stick that has the same speed, timings, and voltage you should be fine. It's rare for most consumers, even people who are overclocking to hit this though. For example, 1st gen Ryzen was really picky with RAM and had trouble with higher clock speeds, running just 2 DIMMs could help a lot on it. 4 sticks of DDR5 is a bad idea , 4 sticks of ram is double the stress on the memory controller and that gets amplified the faster the ram is, at ddr4 3600 was a problem already, at DDR5 speeds (6000+) is way worse, to give you an idea the max officially suported by the CPU when running 4 sticks of dual rank (4x32gb) of DDR5 3600, anything above If there are all the same sticks it doesn’t matter at all. Running dual channel is a huge improvement over a single stick. I asked in the store and they have not exactly the same brand ram, with same capacity and frequency (16 gb, 4800 Mhz, ddr5) but with different CL (40, and mine is 38). EX: MSI compatibility. I texted each stick individually in each dimm slot individually. But this is just up to you because its your money. Planning on building a computer but need some advice? This is the place to ask! /r/buildapc is a… If you want to run 4 sticks you should do your best to stick with same clock and timings. Buy ram according to year, make and model laptop and specifically model number. If you do put all 4 sticks in, let us know how they fare together - i. The next way to tell would be Running Memtest86 multiple times and dismounting all sticks minus 1 to see if that's an issue. Welcome to the official subreddit of the PC Master Race / PCMR! All PC-related content is welcome, including build help, tech support, and any doubt one might have about PC ownership. The tech specs page on lenovo is pretty sparce too, I'm not 100% certain you have 4 slots to install ram into, make sure you do before your purchase. That doesn't mean that you're guaranteed to be able to run 4 sticks of RAM at certain frequencies or timings on all motherboards. 2 sticks of dual is a bit better because you can use them on 2 dimm boards and a lot of 4 dimm boards use the daisy chain to The computer works perfect except when I have 3 RAM sticks (no matter where I place them). If you have tested all 4 ram sticks using a single slot, use a different slot and a checked ram module to see if that's the issue. For reference, using this kind. My current ram has rgb and id like to keep that so i will be getting the trident gskill ram. Try this one final thing. My PC wan't boot if all 4 RAM sticks are in MB slots. If it supports 4 sticks at a certain speed it'll show up as DIMM4 in the comptability manual. My question - is it an issue if the RAM stick are different but of the same brand? All of their specs (speed, voltage, form factor). Reply reply But are they the same speed? Just joined this subreddit to ask a similar question, planning to upgrade to 12gen Intel, and just bought 2 new ram sticks at 3600mhz, my current build has 2 sticks at 2400mhz in dual channel, my question is if I can put the 4 sticks in the motherboard and see no problem whit throttling speeds or is better to just use the dual ones (I'll be putting the 3600mhz in Check your mobo manual, but you can very likely use 4 sticks of 8gb (for 32gb), 2 sticks of 16gb, or 4 sticks of 16gb (for 64gb). Hey all. Ram in a 4 slot board has be be installed in the correct slots for it to run dual channel. Back to the highway analogy, a quad channel system has 4 total highways (each with two lanes) and can do 8 sticks of ram. There's several types of ram and Not all computers can take the same amount of maximum ram either. 4 sticks is harder to run than 2. It's not just compatible with your motherboard. Try to use the same RAM if you can. 4 sticks will often not overclock as high as 2 sticks. If you buy RAM with different specs, then the memory controller will simply slow down the faster RAM to match the specs of the slower RAM. It's more important to use high quality memory modules, brands like Samsung, Dell, Hynix, or Micron (not "Crucial by Micron"), which is fairly cheap when bought used on eBay. I'd like to just use all 4 and have 48gb of ram but I seem to find very conflicting results online on if this is okay or not. is it faster having 16 GB, or a mixed 24 GB - and if the latter, if there are any problems. Not all mobos or RAM are created equal. Since I lurk in this subreddit, I have seen people saying that CPU with dual channels won't work well with 4 sticks of RAM. Usually when running >3200MHz it's best to buy a 4-stick kit to ensure that the XMP profile is geared for 4-stick operation. Boot into Bios make sure no XMP is on if it is turn it off. So 2 sticks of dual rank or four sticks of single rank. Combining kits at XMP is generally not going to work most of the time, because the ICs may be different, the binning may not be exactly the same, timings different, etc. Generally more of the realm of professional OCers. While back I upgraded my motherboard and RAM. 32 or Samsung C-Die. Boots and runs at XMP anywhere from 5 minutes to 1 hour, however the computer will freeze and crash (restart) after a short while. 1 each is upgradeable, with the other soldered in. Is problem with CPU ? I attach image when PC boot with 2 RAM sticks on XMP You absolutely need 2 sticks of ram at least. Since no1 mentioned the most important part then, get 2 ram sticks, in dual channel. Rank and channel are not same things Edit: also under spd you can select individual ram sticks and choose and see what the rank is. However I found another that's 4 GB. Hope this helps! Before ordering, I made sure they had the same speed(3200mhz)and same wattage(1. Overclocking aside, 4 sticks is only a problem if you are obsessed about a higher ram mhz number rather then higher raw performance. This stick is important, as the other sticks will always need to be set to the same voltage as that particular stick once they are inserted together. For anyone who doesn't believe me I say this, go get some 2gb ram sticks and 4gb ram sticks, 2 of each for the experiment. To get all 4 sticks to be the exact same white, you must do one thing, and only one thing: Learn the difference between their/they’re/there. And besides, you'd get higher ram frequencies and possibly tighter timings more often than not on 2 sticks vs. mhz by itself is meaningless. If you use a different size stick you lose Sep 21, 2023 · If you have three RAM sticks, leave one slot next to the CPU empty and install the sticks in the remaining three slots. Tried to isolate the issue and figure out which stick of ram went bad (I had four sticks of G Skill Ripjaw @ 16gb each). So if you properly insert 4 sticks of ram, you’ll be using 1 lane of each highway. 7M subscribers in the buildapc community. Make sure it boots normally with all the RAM. YOU'RE PROBABLY GETTING YOURSELF STRAIGHT TO A DEAD END. There's nothing wrong with having like 8 GB + 4 GB to get 12 GB, etc. Depending on the RAM, it is possible they'll downclock themselves to 2400 due to not matching CAS and Brand (manufacturer). ) You can never have enough memory. If you want fast get x2 sticks of ram. Archived post. However. The catch is in what you're trying to do with it. Then shut down, and add the new RAM. But when mixing RAM speeds, and using 4 modules vs 2, RAM overclocking/speed is always a bit hazardous. I was thinking about buying a set of 2 32gb sticks, sticking one each into both our laptops. Literally 20-30% more performance by just having 2 sticks, instead 1. I’m thinking of buying a single 8gb ram stick to install with one of the 4gb sticks giving me a total of 12gb. Good luck, and enjoy :-) Reply reply 4 sticks of 8gb or 2 sticks of 16gb or 32gb. What I am unsure of is do I need to add 2 more sticks of ram that are exact to my existing ones? Here's my PC build. i just bought a new cpu ( ryzen 5 3600 ) and everything works fine. And also do what the other post said before you remove the old ram…go into Bios by hitting delete constantly as soon as you boot to get into bios, disable xmp ram profile. The 4xSR configuration is not ideal, because of the daisy chained topology and should be avoided if possible. Yes, that's all you need to do. Nevertheless if you can't afford both, mixing and matching RAM from different brands will never hurt your system (unless you are using totally different sizes and speeds). so get 2x 8gb. I have trouble finding the official AMD statement for this right now, but I remember that this is normal. You will be fine if you mix a Kingston 2400mhz and a Corsair 3000 for example, but the Corsair will be run at 2400 unless overclocked back up to its spec, but the other the stick will need to be able to match. New comments cannot be posted and votes cannot be cast. It worked the first time when I had single rank amd dual rank ram but did not work with 4 dual rank ram sticks. Both ram sticks have to do every operation at the same time, therefore they will automatically run at a speed both can manage, which is usually the slowest of the two. So there is no ddr3 or ddr4 1499, my guess is the stick is a 3000mhz stick since it is Double Data Rate 4 (DDR4) the software is reporting the base speed, not the clock doubled speed. Welcome to the official subreddit of the PC Master Race / PCMR! All PC-related content is welcome… In your case, if you need more RAM, the best solution would be two 8gb sticks. Yeah if you run them at xmp, which you should because you would be wasting money if you buy 3600 ram and run it a 2200, 4 sticks of ram are more unstable than 2. The easiest way to do that is to get another copy of the same part number you already have, but if you're willing to scroll through spec sheets until you find something that matches you might be able to get a better deal. The bonus to having 4 ranks is that they can all be accesses independently. It's the same model and it has the same specs (2400Mhz & 15 CL) but Im not sure it will work ideally since the sizes are different. If the OS reads or writes data to a specific address and one dimm can deliver the data within the expected time frame but the other doesn't, bad things happen. I want to move to dual channel but I cant find another identical 16GB one. It may not be as fast as having only 2 of the same sticks for dual channel, but it should work. You'd think if a motherboard has 4 DIMM slots that going 4 RAM sticks would be normal, if not expected. If you have four slots and four sticks, you can install the sticks in any slots (again, deferring to the channel guidance provided by your motherboard manufacturer). I had 32 gb in 4 sticks, at least once a month I got a blue screen, changed to 64 gb in 2 sticks, haven't had a crash ever since. If I put Ram in Slots 1 and 3: Only runs at 2133, does not run or boot at XMP If I put Ram in Slots 2 and 4: Runs at XMP If I put Ram in ALL 4 Slots: Boots and runs at 2133. So if one kit is 3000cl18 and one is 3000cl16, to my knowledge, your best bet would probably be try and adjust the timings of the cl16 to match those of the cl18 leaving I have one 8 gb 2933MHz SODIMM DDR4 ram, do I need to find out which manufacturer made it and buy the same exact one or one with the same specs but different manufacturer works. Ram differs slightly in the internal operation, even from ram produced on the same day and run. The ram is not labeled when you buy it to tell you which rank you are purchasing. I have completly new ram sticks (after RMA), then there is no issue with RAM and same with MB. The problem is that this creates two issues. On Ryzen 5000 and below you can get better performance with 4, but that's due to single and dual rank sticks, if you had 2 dual rank you'd have the same performance. This might bring some stability to your system when all 4 RAM slots are populated. 2v) as my current ram sticks but they're a different brand. The os is expecting all the ram on a specific channel to work at the same speed. A quad channel system can do 4 sticks much easier. When you put the ram in dual channel you are taking both ram sticks and putting them on the same parallel bus, going from 64 to 128bit bus for example. Here's the thing, you CAN do this it doesn't necessarily mean you SHOULD, some ram is compatible some isn't, and you're better off running the same sticks not only for aesthetics but also because it'll generally cause less headaches when this inevitably goes wrong at some point 2 ranks per channel is optimal. My new mobo has 4 slots as well but I doubt I'll ever fill them, at least anytime soon. To keep this short, there are very few ram and motherboards configuration that can get 4 sticks of ram to overclock high past JEDEC speeds and those configurations arent any good either. I know my question might sound a bit stupid but would adding another 16gb Corsair vengeance 2666mhz fix the problem? My current situation is that I have 2 sticks of 8GB (DDR4), but I keep running out of memory so I’ll need to upgrade to 32GB. I went for 4 sticks of RAM (4x8 Gb) because of aesthetics. If you aren't using a ram overclocking profile, it will most likely work just fine. You might get slightly better performance at stock speed with 4 single rank sticks vs 2 single rank sticks, as you would with 2 dual rank sticks. That's simply because more DIMMs = more memory controller stress. Using identical sticks is optimal, but you can still mix capacities and brands. But I compile software from source, and large packages like chromium or firefox gobble up ram when certain optimizations are made. so basically under the spd tab you can select each of the four rams and see which rank they are. This depends on your mobo. Memory should be added in matched pairs (so, add 2x8gb or 2x4gb, not 1x8gb and 1x4gb), but different pairs don't need to be of the same size (2x8gb and 2x4gb is perfectly fine, though you'll want to check your board's manual to see which slots each pair should go in -- some boards are picky about things like "the largest pair should go in the You have a 2666mhz stick, so, your second stick need to match size (8gb) and speed (2666mhz) in order to both run at the same speed. Use a bunch of plug-ins and monitor your ram use. My simple question is this, because its quite hard to source RAM with the same exact part number, can I fill the 2 x remaining DIMM slots with 2 more sticks of 8GB DDR4 2666MHz RAM, but from a different manufacturer? Additionally, could I buy two more sticks of 8GB Corsair DDR 4 RAM, but with a lower MHz. You only need to worry about order when your pairing different size/speed ram. Second, the memory controllers on current CPUs can't always handle even moderately high memory speeds with either dual-rank (32GB or more per stick) or dual-DIMM per channel (4 RAM sticks). since extra sticks mean more strain on the memory controller. Hey guys, I'm currently planning out a new pc build and I'm looking at 32gb of RAM spread across all 4 slots on my motherboard. Other potential sources of damage were the motherboard slots were damaged. after i update mobo to 1616 latest bios, things changed. I am looking to add 16gb of ram. At the same time though, some products are more sensitive then others. * Optimally all 4 sticks will support the same speeds and timings (ex. That said, when mixing and matching ram should default to the slowest common speeds. If you have only 2 you have a higher chance of running fast sticks at low timings as the memory controler is less strained. If the motherboard still won't accept 4 of those RAM sticks even with XMP off, then there likely isn't much you can do. EDIT: I do have XMP turned on. Putting 4 stick into a consumer board (AM5 / Intel Socket 1700), results in Dual Channel with 2 sticks per channel. BOTTOM LINE IS DON'T BUY RYZEN 5 3400G AND TRY TO MAKE IT WORK WITH 4 RAM STICKS. Some RAM configurations just don't work out too well for some sticks. One of the sticks has version number 3. The reason the sticks have different version numbers is because I bought only 1 stick initially and intended to buy another one of the exact same type later down the line, which I did. 12M subscribers in the pcmasterrace community. if you have 2 sticks that are DDR4-3600 and buy 2 more but the rated timings on one pair are 20-26-26-46 and the other support up to 18-22-22-42 then the best you can hope for is the 'looser' timings of 20-26-26-46 that will feel ever so slightly slower, and you may have to reduce the speed and/or timings even further to DUAL RANKS: for rank interleaving - one memory bank can be accessed by the CPU, while the other can undergo a refresh cycle, we get another ~3-5% by using RAM DIMMs that have chips on both side (DUAL RANKS) or if we populate all 4 DIMMs with 4x single ranked memory. . SO DON'T BUY 4 RAM STICKS FOR THIS MOBO :) ] EDIT2: Aparently it's not mobo's fault. In my experience with DDR5 (granted a very small sample size), if a module is rated for DIMM 1, 2 then it supports slots 1 & 2. Rinse and repeat for the rest of the slots, with this weakest link. (Somewhere it may say multiplier x2) the ram speeds and timings will default to the slowest stick of ram when using different memory. Most people do not need 128GB ram, far overkill for most. Turn off clear cmos remove all ram install two sticks one in each channel per the MB recommendations. 4 sticks are harder to run at the same speed as 2 sticks, but 4 sticks at a slower speed will be faster then 2 sticks at a higher speed. The ram runs at the lowest sticks you have in your tower. To explain this in some more depth, DDR-4 dual channel (which is pretty much all consumer MBs) support 2 channels with 2 ranks per channel. I have tried 2 ram sticks (all combinations) and they all work in all 4 slots, but the moment I add a 3rd one it doesn't work. I definitely would wanna get the same pair ramsticks. i've same mobo with kingston fury KF560C36BBEAK2-32 6k mhz, on 0821 bios all 4 sticks worked on expoII 6k but very long boot time. The other 10% of the time, you may need to clear CMOS, update the BIOS, try one stick at a time until it recognizes (before shutting down and adding the others), etc. You can do 4 sticks of single rank ram sticks, or 2 sticks of dual rank ram sticks. mixing different brands of RAM should work fine. My question is if I should continue using the same kind of RAM for the other slots, or if I'm good to pick up something newer. If you combine an 8GB stick and 16GB stick you'll end up with half of the 16GB stick running in dual channel mode with the 8GB stick (basically the same as 2 8GB sticks) and the other half of the 16GB stick will be in slower single channel mode. 32 was not enough on my last CPU with even more GB/core and 64GB is VERY tight on this cpu. You need to make sure the RAM stick product model matches exactly. Usually they are market by colors. 7th and 8th gen Intel were also testing slightly better with 4 sticks 3200/3600MHz over 2 sticks, but there was only a noticable difference (literally 2-4 percentage points) for ram within these clock speeds for unlocked CPUs. When checking prices online, I often see that packs of 2 sticks of RAM are usually less than half the price of packs of 4 sticks of RAM of the same model and clock speed, making it cheaper to buy 2 packs of 2 instead of 1 pack of 4. What makes me laugh the most is I initially scoffed at it. This is a known but rarely talked about fact. Jul 26, 2022 · You can do both. It's confusing and might dissapoint people that do expect a decent overclock and prefer lower latency over bandwidth. RAM sticks run without problems on XMP profile. There is no or very little heating difference. For both intel and amd the memory controller and consumer motherboard are optimized to run 2 sticks of ram fast. Case in point: I tried running 4 16 gb sticks of gskil rip jaws ddr4 3200 ram. What I would recommend is to go in the BIOS prior to the RAM upgrade. (and all 8GB dimms these days are single rank and some 16GB dimms are single rank too. So just to say that 4 sticks is always faster is not true and should not be spread here as the only truth. 6. Will it work ? Ram is speced to run at a specific speed. Rank is a characteristic of the ram stick and not related to dual or single channels. If capacity is mismatched, it will usually run in single channel mode only. memory overclocking is harder the more sticks you have. On Ryzen 7000 having 4 sticks kills the performance. I’m just wondering if I can choose any ddr4 stick to pair with my current one or if I need one that’s the same model. First channel is slots 1 & 2, second channel is 3 & 4. My GFs and my Laptop both have 2 8gig ram sticks each. I currently have 8gb (2 x 4gb) of ram which I feel is severely limiting my performance for higher end games. If you have an AMD Ryzen cpu, you should get a whole new kit of ram. 3000-3200mhz value select ram is cheap as f. The validity is this: your motherboard has 2 channels. For the same desired capacity, ECC type and registration status (in your case, 16GB, non-ECC, unregistered) more sticks are better up to the limit of the number of channels your CPU's memory controller has, or the number of channels your motherboard exposes if that's lower, so for ideal performance you'd want 4x4GB sticks (or 4x8GB if you wanted 32GB of RAM). e. So I have a 16GB hyperx fury ddr4 2400Mhz CL 15 stick in my PC in single-channel mode. Most brands will allow you to upgrade the RAM and hard drive / SSD without voiding the because most consumer motherboard topologies and memory controllers are not designed to run 4 sticks of ram fast, so people with 4 sticks often end up having to run ram slow to stay stable. Do not try running xmp on ddr5 with more than two sticks it’s a known issue. 4 sticks raised latency for me on daisy The only problem, irrespective of using different or exact same RAM sticks, is that utilizing all 4 DIMM slots always results in less RAM clock headroom – so you might not be able to reach DDR4-3600 anymore. PCPartPicker Part List Different frequencies are not a big issue because the system will adjust to the minimal common frequency of all the ram sticks. 44V to stabilize the same settings in slot A2. So far I have updated my BIOS and, as I said, tested each pair individually, but when I add the other sticks I cannot get to the BIOS at all. Having 1x16gb stick would be the least desirable option you have. If you simply upgrade to 4 sticks, make very sure that it's the same RAM model as you have already installed. What CPU are you running? Ryzen is much more sensitive to ram speeds than Intel is. And if I do see a need to upgrade it'll probably be to a 4x8GB kit myself, but only because I've discovered the addiction to RGB. What will happen is this: The system will use the ram in the first pair of channels first, and then in use the second Daisy Chain with 4 sticks will mostly top out at 3600 if you are lucky that is. If your board only has 2 ram channels it'll run dual channel if you're running 2 sticks you're just limited to two sticks, and probably the maximum amount of RAM the system will support will be less. All four sticks failed the memtest individually in each slot individually with thousands of errors. etc. Say you have 2 sticks at 3200 and 2 at 2400. Find an 8GB stick that has the exact same clock speed, CAS latency, and timing as the one that's in there now. Everywhere I looked, ram always came in sticks the same size, is there a reason for this? Is it feasible to upgrade half-way? 4 dual rank sticks are expected to have difficulty achieving the same speeds as 2 dual rank sticks. Each stick of ram gets its own highway (channel) to itself. Then make sure to enable XMP/DOCP in bios. 4 is normally more esthetics or they buy a 16 GB kit and later add the same kit for more ram, which is fine too (as long as it’s the exact same kit or same spec/timings) Reply reply Well there is a reason why manufacturers sell them as pairs like 4+4, 8+8 etc same speed and same cas latency. If, for example, you're wanting to run 4x16GB modules @ 4000MHz on a Ryzen 3600, the chances of getting it working at 4000MHz for all 4 is pretty doubtful. Most or all motherboards with 4 slots for RAM will support using all 4 slots at once. It usually works, but not always, even if you use the same Feb 6, 2024 · No, you can not buy the same exact sticks. DIMM 3 is the weakest of all four sticks, as it needs at least 1. PC run only when, if I plug only 2 RAM sticks and leave 2 ram slots empty. The problem with that plan is there's an absolute shitload of timings involved with memory. If you use only 2 sticks (usually best in slots 2 & 4) Putting 2 sticks in each channel means the motherboard has to route data between each of 2 sticks in the same channel. 4 sticks is NOT 'quad channel'. As long as they have the same specs and are the same capacity you should be fine. now if i activate expoI,II or Tweaked mobo jumps to safe mode after a short boot fail and boom 3600mhz speed. First use 2 sticks of ram (order doesnt matter), boot pc, once youre on the home screen, shut doen your pc and add the third stick in any order, then boot up your pc and when u arrive at the homescreen, shut down and finally add the 4th stick and boot. Just use 2 sticks and you'll be mostly fine. If you do have 4 slots, the good news is you don't have to match your ram. Side question, the reason I'm looking to upgrade is sometimes my recorded audio for a given game clip is distorted, and I figure it's Chrome eating up the memory. In theory, if all specifications are the same which meant same size, same frequency, same timing. I have tested each pair individually and can boot with no issues, so I know all 4 sticks are (or should be) good. If speed or latency is mismatched but capacity matches, it will just run at the slower speed usually. I dont know who needs to hear this but if youve tried everything and the pc still wont boot. Depending on motherboard and ram this may or may not work at your desired memory speed. ) Modern CPUs spread their memory access over 4 banks of memory, some expensive ones even 8. The space isn't for cooling or looks. short answer, you can still put different brand RAM with the same frequency in the 2 unused RAM slots long answer, not all modules of RAM are made the same. on 4 sticks. Other Intel chips might also reflect this, but these are the only ones I know about. Disable XMP/DOCP to run the RAM at default speed. Thank you. You don't need to match them but it's recommended for the best gaming experience. Also if this is . I have no actual knowledge to pcbuilding and had bought my pc prebuilt so I dont know if have 4 sticks compared to 2 sticks really makes a difference. Using 4 sticks will also not result in double the bandwidth, because it is still Dual-Channel. 2 sticks of at least 8gb 3600mhz CL16 ram is the best option for Ryzen. 1. If you cpue has 4 ram slots, then 1,3 and 2,4 are dual channel. If you want to overclock however, 4 sticks is more difficult than two (depending a little on motherboard toplology). Sorry if it's a dumb question but the TLDR is that I want to add to my 2x8GB RAM another pair of 2x8GB sticks, so that I can have 32GB of RAM. 8GB modules and some 16GB are single rank (so you need to fill all 4 slots to have access to 4 full ranks. You don't have to match the memory, and sometimes even when you get the exact same model it's actually made from completely different chips. If you want capacity you need to accept the tradeoffs of x4 sticks. You can get quite a performance increase (up to 10%) running four sticks of ram vs 2 sticks if they are single rank. Some machines are limited to 8 GB, summer limited to 16 GB, some can take 32, 64, 128 GB. The same RAM kit I previously bought is on sale and it would be much more realistic for me to just buy that rather than sell these sticks and buy 2 sticks of 16GB. Ram is speced to run at a specific speed. Shutdown the pc install all 4 sticks if no boot RMA MB and RAM. So why is it such a sin that if you do go with 4 RAM sticks (same model, mhz and cl) there's a shitton of potential issues; system not booting, random shutdowns, unsupported/untested by mobo manufacturers, slower working speeds, slower boot time, 2 is absolutely fine. you'll have the heat and power consumption of 4 sticks instead of 2, but its not really and issue, ram draw so little power that they dont even need active cooling, as you've probably seen. First, DDR5 is very sensitive to signal integrity, and adding additional slots decreases signal integrity. The best option in your case is upgrading to two of these 3200MHz 16GB sticks with the same size and speed. 31 or Micron D-Die, while the other stick has version number 4. Yes, as long as it's not an XMP kit. Totally depends. I love how 4 stick of RAM looks compared to just two sticks. It's the 2 sticks per channel that is causing all the problems. It’s a stupid pet peeve of mine. So if your CPU can do quad channel memory, you want to fill 4 memory slots for best performance. Next open up Adobe Audition or any other ram intensive application and start a new project. Some boards don't play well with different ram, I've even had them reject 2 identical sets of 2x8, which is why ram manufacturers often will package kits like 4x8 for a little more than double the price, as they've been tested as a set, have the same firmware, etc. Second best, if your motherboard supports 4 sticks, would be adding 2 more 4gb sticks. If it is okay to use all 4, does it matter how they are configured in the ram slots? I dont know who needs to hear this but if youve tried everything and the pc still wont boot. qfkv ctyzgc icitn jpno krbsuepr edrdtf pddky vzbfb gsxlxtw yigil lmgd ofeojt glakgu kduewyz rkn
