Stumbled upon a couple of videos on YouTube where they recommend using Ryzen master to undervolt the 7000 series CPU for lower temps and better performance. Another dilemma is the motherboard. Also you can always undervolt the CPU with a negative curve offset and add a power limit to really bring the temps down with little to no performance hit if it really bothers you that much. 105W TDP (aka 145W actual power) would have been fine for anything in the 7000 stack. Well afaik the 7900x is pretty comparable to the 13700k in productivity and the 14700k has 4 more e-cores. CPU might be unstable if you undervolt too much. 8 p-cores cores should technically be a little better than the 7900xt's 6+6 for gaming. Don't trust the Ryzen Master results at face value. Also, weirdly, RT titles did not stress the card harder than pure raster, but this is in terms of hitting instability from the undervolt. Just want to share the scores as someone might be interested On the side note, my 7900x can run 5. 25GHz on all cores with a slight undervolt (30 offset), but I can't quite seem to get the full 5. We saw rumblings of this kind of thing in Those Ryzen 7000 CPUs can be quite a bit power hungry if you let them behave like they want to, which is why today we're setting this R9 7900X to be more performing in multithread AND more Dec 3, 2024 · The simplest thing is to use AMD Ryzen Master, activate curve optimizer if it is disabled, select all cores and click start optimizing. So I curious how much… May 3, 2021 · ASUS ROG STRIX B550-F GAMING (WIFI) RYZEN 9 5900X COOLER MASTER MASTERAIR MA610P RGB 2X16 3000 MHZ CORSAIR VENGEANCE RGB PRO MSI GTX 1080TI 11GB GAMING X SSD KINGSTON UV400/V300/Samsung 860 EVO | WD BLACK 5TB | WD BLUE 1TB AEROCOOL KCAS 700WFULL RANGE CORSAIR GAMER 4000D AIRFLOW BLACK I It's not just a 5 fps increase in the 100s, the difference is almost from Ryzen 7 to Ryzen 9, with sometimes 20 and sometimes 50 fps difference in CPU bound games. Unfortunately, nowhere says how to do this undervolt and what's a good process to Ryzen 9 5900x idle temps 28. 7900x, you save $50 and are all set for a 2025 CPU. 45,9min vs 46,8min. But TS doesn't work with AMD cpu, so I wonder if there is anyway around to undervolt and lower the clock speed in order to lower the temp. Ryzen Master is useful for users who don’t want to run a 24/7 overclock. It's not clocking down because of thermal throttling, it simply cannot go any higher. Do you think it's good? For indication on my rayzen 9 5900x Base temp : 88 °C After : 76 °C -13. One of the best tests I can offer you is to find your favorite extremely gpu taxing game, start streaming to discord with all settings bumped, and undervolt from around 1120mv until you crash. Like I said, this stuff is super foreign to me and I've been building since the late-20th Century. I did a dynamic undervolt, with 80 max temp and -20 of CO maybe I can reach -30 or switch to static undervolt. Also I'm running mine with All-Core -30 and a 200Mhz OC. It's not my first build and I haven't seen this probl The 7800x3d has more cores that are linked to these large cache reserves compared to a ryzen 9. It's alright that you took the 7900X: The 7900X3D would have been a worse choice: only half its cores have the extra cache which makes it potentially fiddly / hit-and-miss in games unlike a 7800X3D, and it costs extra versus the non-3D-variant that you got while not being faster in workloads that actually profit from all its cores. Smaller die=harder to cool. Feb 17, 2025 · 7900xtx nitro+, 2900 MHz, 1120 mV all games stable, fast timing 2714 MHz VRAM. a dual 120mm tower cooler like the thermalright Peerless Assassin 120 vs a 240mm AIO liquid cooler), there's basically NO advantage of using a liquid I just finished my first pc build and was wondering if i should undervolt my Ryzen 9 5900X with PBO2. 25GHz. CPU temperature is also lower at 91. A quick test with Curve Optimizer “-30” (minus 30) shows the Cinebench R23 performance is 5% better than stock. Please help me to lighten up the I've just built my first system with a Ryzen chip (7900X) and the lack of clarity on vcore, news articles and general "ooohh voodoo" about how it works are really irritating me. And the die of an Ryzen 9 HX is 5nm so smaller dan Intel i9 HX 10nm. My cpu is 33 degrees C while idle. Get the Reddit app Scan this QR code to download the app now But when idling my Ryzen 9 7900x runs between 55C and 60C. Now if you think you could Undervolt or -CO to get lower temps, thats also very limited with the RYZEN CPUs. Some CPU's are god-tier and can happily undervolt to the limits of Curve Optimiser, others can't budge a single point or even need more added. The longer boost tends to be more beneficial for cpus vs aiming for top boost speed. cores 9-16 @ -28 (2 cores at 24) PBO 2x and +50mhz On a cold boot MT - 39800 Single - 2070ish Took me 3-4 days to get something stable 95c is expected, if you want lower temps just undervolt vcore you can get similar results and shave 10c but won’t boost as high anymore (-110 to -120mv was stable) Oh and the thing with Ryzen 9 HX models is that they will boost to thermal limit, unless you set the wattages manually. Ryzen 7000 series processors are designed to operate at 95 deg celsius (89 if it's an x3d chip) and use more or less power to remain at that temperature. Is there any good guide out there? It seems like this cpu lost the silicon lottery if it can’t handle all core undervolt. CPU: AMD Ryzen 9 7950X3D PSU: Seasonic Prime PX-1000 BIOS Version: 2613 Memory: 2x 16GB DDR5 G. Yes, I do have Resolve Studio. This might get removed because it's not relevant but I noticed some major differences between my two CCD clock speeds and temperature on my Ryzen 9 7900x. Using Vsync or capping framerates allows me to maintain a nice 55c (default Wraith Stealth) when gaming, even while running Thats a bit Extreme Tbh. 6 GHz. Initially the game would be running the cpu at a cool 65 degrees but as soon as start playing a game for a few minutes it goes to like 81 degrees and just stays there while boosting between 5100mhz to 5250 mhz. AMD Ryzen 9 7950X temp question Others/Miscellaneous hi everybody , i recently got myself a AMD Ryzen 9 7950X 16-core CPU , while gaming it comes to 80-82 degrees celcius and sometimes (rarely) peak at 94degrees . So I got the Ryzen 9 7900x, the entire PC is brand new, the CPU has always chronically overheated ever since I got it It goes up to 98C without seemingly thermal throttling. 21v at max load) on the vcore which has dropped max temp on AIDA64 stress test from We would like to show you a description here but the site won’t allow us. 6GHz/76MB CACHE/AM5) Motherboard. I've tried to lower the wattage in Eluktronic Control Center but no luck. You would know if you used something like that. The list of supported processors is limited to Ryzen 2000 CPUs and newer, with feature support differing between CPU generations. Try first a -5 then -10 and lastly a -15 on all core and see how it goes, keep an eye on temps and vCore. Currently using Ryzen 9 7950x, ASUS tuf x670e motherboard, 64gb of corsair vengeance DDR5 6000 MHz RAM. 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 main difference between them is the CPU's. Ryzen 9 7900 undervolting I'm still trying to understand the nuances of modern overclocking (used to OC all my desktops, but not for 12+ years). Welcome to /r/AMD — the subreddit for all things AMD; come talk about Ryzen, Radeon, Zen4, RDNA3, EPYC, Threadripper, rumors, reviews, news and more. Tản: noctua nh-d15 chromax black- case: Lian li lancool-216+ ba con lian li p28 Also there's no way to fit a 7900x in a 500 quid budget. After applying a -30 to the all core curve optimizer and disabling limits, it significantly reduced my my cinebenchR20 score. tjajjxuexbwbpgwwjtaxznnqcokzxdiixayhnkuyrcfzldxhmakfn
