Onyx: A MD Ryzen 7 7800x3d / ASRock Taichi 7900xtx OC / Gigabyte B650 AORUS Pro AX / G. While 60-70 is well within the thermal limits of the chip, that's a bit high idling, especially if using an AIO. Max clock went from 5. The thing is, the 7900 and 7900X are at the same price in my country, and the extra power of the X version would be nice to have if i need it (or in colder months to warm my self haha) so i was wondering if i could get the same efficiency in a undervolt 7900X. Darktide get unstable at any level of undervolt. It is a set of default values for max power, current, etc. 6Ghz. You can use that preset, or pick just about anything in between that preset and full power, by fiddling with the settings individually. I also play on 3440x1440 (when supported of course). Skill Flare X5 6000 RAM, installed on a Gigabyte X670 Aorus Elite AX motherboard. Discover discussions, news, reviews, and advice on finding the perfect gaming laptop. 1ghz and now it's better. Too late to return the 7900x now it seems. I originally built a new machine with Ryzen R9 7900X, 32GB (2x 16GB) of G. Here is an example with Control at 3440x1440, max settings and a custom RT setting. As shown in linked video an undervolt followed by a setting a lowered power limits seems to perform on par with stock whilst shaving off 50W. I genuinely don't believe anyone's undervolts are completely stable on reddit. Regarding the CPU I'm using the Hardware Canucks video of low profile coolers and ryzen 7000 as a baseline, where the 7900x will get around 80c in gaming for eco mode. With the above settings, average actual core clock in-game hovered around 2850-2900 MHz but would fluctuate depending on what was on screen. Yeah starting review stating 100% fan speed on a 420mm Aio is still 90C+ is not a great first impression. true. I recommend the power saving settings: Min/max clock: 2300/2400mhz Vram: 2650mhz Voltage: 1120mv PL+15% Gives maximum stability while drawing less than 320w without losing any performance. Still need to enable Expo and Eco Mode when I find proper videos. I’m targeting a 95W PPT with a boost override of -100 for a 5. But even an undervolted 14700K still needs a 3-fan AIO if you want to load all cores with rendering or something (I assume that's why you're considering a 7900X and not a 7800X3D), to work with air cooling you'll have to limit it to ~200W PL1 or less - but that comes at the cost of some performance. on high settings at at least 60 fps (current laptop can barely do medium) and also stream / record / edit videos, don't know much about computers though I am considering buying a Gigabyte motherboard. In short, if this PC is used for productivity and gaming, get the 7900x and benefit from having more cores. I've been playing around with my 7600x a lot recently tried out manual ECO modes, followed Optimum techs' guide to undervolt (managed to get a stable -30 in curve optimizer), and tried some preset settings that my motherboard has as well. With the undervolt package is still 40W at idle while cores only are 7W. Low temps profile. 277 votes, 119 comments. 8 p-cores cores should technically be a little better than the 7900xt's 6+6 for gaming. Welcome to /r/AMD — the subreddit for all things AMD; come talk about Ryzen, Radeon, Zen4, RDNA3, EPYC, Threadripper, rumors, reviews, news and more. Ryzen also offers you fine-tuned undervolting options with their Core Optimizer feature as part of Precision Boost Overdrive (PBO). You’ll have to experiment a bit to see what works. 38v to 1. 12 and it crashes while I was opening a couple apps at the same time, so I'm pretty sure its working, which is awesome because I was scared I wouldn't be able to undervolt Oct 1, 2024 · I am using a Gigabyte B650 GAMING X AX V2 Motherboard with a AMD Ryzen 9 7900X and I would like to under volt the CPU, I have looked on YouTube for information about this MB but most of the videos are only about reviewing it. EDIT: the best way to indirectly "undervolt" these CPU's, is to limit wattage using PBO I guess. Right now everything went back to auto in the BIOS settings due to the fact that I unseated my CPU to clean it and to replace my AIO cooler. And btw, the 7800X3D is still inefficient at idle with around 25W of power usage (around 60W while gaming), but it's much better then the 7900X. Undervolt! For the longest time AMD cards has been undervolting kings. Edit* This is my current settings as I have been able to get it to work. It's almost exactly like overclocking, just in the opposite direction. Gaming with the iGPU it is nearly impossible to make the CPU be the limiting factor for framerates. Edit - just found their video, identical settings so we have a 1:1 comparison. I have Red Dragon 6800XT, after some weeks testing with Time Spy and Port Royal benchmarks I finally found stable settings: Min. Here's my bench. New 7900 non x would fit waaay better in that tight build. If you aren't shocked that I could overclock my processor significantly, you shouldn't be shocked that I can undervolt my GPU. The PBO2 automatic setting with PPT 50 Watts, throttle temperature limit of 85, and Curve optimizer magnitude of -40 used to make my system efficiently but dropped my CPU voltage close to . 775V. ROG Strix B650e-f 7900x G. I would advise you to limit its tdp like the non X version 7900 and it runs great still. Just curious as a 7900x owner who can't find others, what other settings did you end up using and what mobo/cooler? I found that -27 co with pbo enabled and xmp2 was really the quickest I could get but the curve optimizer requires crazy time doing a per core I don't overclock because no matter what I do the gaming experience is exactly the same, except it runs hotter and draws more power. Same goes for an 7900X, it's a very good processor to undervolt slightly without losing any performance. The presets on my board are just limiting temp and applying an undervolt. If you would like to learn exactly how to set the settings then here. Found out 7800x3D is way better based on this subs posts. I use another tweaking utility called Hydra and it did a great power play table mod to my 6900XT, but it's PBO and curve optimizing tool isn't as good as Ryzen Master's auto curve optimizing tool. It exceed that but keep in mind that every setting is completely maxed. If you do the the 7900X, just remember it does run hot, hotter than the x3d one. Looking for a solid reliable windows gaming and streaming PC for <1000ish, wanna be able to play helldivers 2, squad, total war, m&b, uebs2, etc. I know that AMD recommends water cooling for the 7900x, but Tech Power up did measurements on the 7950x and found that good air coolers are more than sufficient to handle the 7950x, and I just value low idle noise. The result captured in the image above was my best score (accidentally put wrong undervolt settings for that result, the correct settings were: -150 P-Cores, -150 E-Cores, -150 Ring), though that undervolt was not stable enough and crashed after third test. R9 7900x: Follow a guide and lower the PBO limits from the crazy high stock settings to something more reasonable like 165w PPT. Not sure why it is working now but I will monitor it moving forward. Clock Stretching is a safety feature that is built into all AMD Ryzen CPUs. The chip is 7% faster than the $589 Core i9-13900K in 1080p gaming at stock and overclocked settings. It bounces around though. From what I've read, you can easily match performance of the 7900x as long as you have adequate cooling. I did a quick and dirty undervolt on the 7950x (0. But if I play call of duty or rdr2 then it barely reaches 80. mezb nadglws zrtvzzdk aaaf vtz voazu bzkq yhqhmf hgt zaacvi
