7900x undervolt reddit. I watched a couple of YT videos on undervolting with using Curve Optimizer in Ryzen Master (figured I'd try it first after getting great results undervolting a 6700 XT with Adrenalin). This helps a lot. 38v to 1. 08v. From forums I’ve looked at, everyone keeps saying to go until you start noticing instability, so I’m wondering if I should keep going or if I should stop? just built new pc,using noctua dh-15, could only fit the 1 middle fan and online says the 7900x is built to run at 95 C 24/7 but im just downloading some stuff and itll jump to like 88 C 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. 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. What I’ve found so far is impressive undervolt capability. Need help choosing between 14900k, 14700k, 14600k, 7950x3d, 7800x3d, 7900x, 7800x and 7700x.

My System: CPU Ryzen 9 7900x CPU Cooler Artic Freeze II 240mm AIO MOBO TUF X670e Plus (non-wifi) with latest bios. Doubtful, I have EXPO enabled on my 7800X3D with an ASUS board and it runs pretty cool after BIOS updates. That’s about equivalent to -150mV undervolt on an Intel system which would be a godlike undervolt. Stability tests passed: Hey all, So I will admit I'm new to undervolting, and am seeking some advice. Games are different and some may work at 1050, while some need 1120 of full 1150. If I wanted to undervolt, just yeet the vcore down in chunks and test. The chip, which leverages AMD's second-gen 3D V-Cache to boost L3 capacity to 128MB, beats Intel's Core i9-13900K in gaming by 7%. I have always lowered voltage and ran a test until it crashed is that the best method or should i also use the min and max freq sliders I have the same card, with the settings you used with 1020 mv undervolt, have you changed anything? Atm I’m running 2300 min 2600 max with 1030 mv 2700 vram. Undervolting 7900x. I'm following the guide from Optimum Tech. It seems like this cpu lost the silicon lottery if it can’t handle all core undervolt. Imagine running a review on a gpu that's had driver updates and being like welp, guess the card runs like shit because the drivers it default came with were Sep 2, 2022 · AMD Ryzen 7000 "Zen 4" processors can hit up to 95 °C at stock settings, with cooling most appropriate to the TDP level. RAM 2xG. By default, PBO2 wants to start CCD0 at a roughly 1. I’m targeting a 95W PPT with a boost override of -100 for a 5. The game is an action roguelike game that is well worth the small $4. With regards to your confusion: 240-280mm refers to an AIO cooler (all-in-one). Wondering if it's going to be viable to run mid-high 30x series GPUs (3080ti) + 7900x with the PCO2/undervolt on a single 240mm rad loop. 25GHz. 985v but the windows time is always drifting, getting late. Port Royal 20,492: https://www. E. Productivity is a touch better in the X variant, but again at much higher power consumption. 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. But the other six cores handle -30 curve without issue. I just got a Ryzen 9 7900X and a DeepCool AK620 CPU cooler and noticed that in a couple specific cases it would turn off, primarily in World of Warships but also when I ran a benchmarking test. Remember to undervolt them for optimal performance! If you prioritize multi-threaded performance and power efficiency, the Ryzen 9 7900X might be the better choice. 40v (seems to depend on core). Temps around 85c under cinebench r23 I have my mem clock on 2714 no fast timing, min freq 500 MHz, max +-3000 MHZ, +15 PL. With intel over the years I just plonked the thing in, and hit go. The restrictive power limit is what makes undervolting work so well on these cards. TLDR: My 7900x is stable (at least from 24 hours of torture testing and ovber 48 hours of normal usage) with a -30 Offset per Core. Overclocking. If you’re doing all core undervolt then your preferred cores is going to limit you. After this has been carried out, performance is pretty much identical. 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. Only assholes do that. Same goes for an 7900X, it's a very good processor to undervolt slightly without losing any performance. PBO boost override disabled. Black, Dual-Tower CPU Cooler (140mm, Black) LINK For my ryzen 9 7900x. Wow, that seems like a banging deal for that model! I just build an ASUS B650-A/7900x/4090FE. Yup, cause its unstable at any undervolt. " Except the 7900x is cheaper than the 7900 on Amazon for the UK, so therefore does it make more sense to drop the wattage down on the 7900x? 26 votes, 21 comments. The best value/ performance case seems like the Corsair 4000d airflow, but it can only fit a 280mm aio top mounted. We saw rumblings of this kind of thing in rumors I finally got around to trying my EVC2 on the 7900 XTX last night and the results were impressive: Time Spy 38,725 GPU score: https://www. I went in using hardware info I found out what the preferred cores were (there are 2) and applied a -10 undervolt. Is that sufficient for the 7900x? At microcenter they were saying 360mm minimum. Trying to go for lower temps/less heat from the gpu. . Probably crazy trying to air cool the ryzen 9 7900x but i am interesting if its totally possible, I know the Noctua DH15 is amazing , but i was thinking about Deepcool AK620 ZERO DARK which i hear is also very good. I've had no issues gaming on this for months but can't make promises as every piece of siloc9n is different and I wish you the best :) 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. AMD variation: Ryzen 9 7900X + Asrock X670E Steel Legend + 2* 16GB RAM 32GB RAM (CL36, 5200MHz) GPU I planning to start RTX 3060 Ti or RTX3070 . And I'm trying to Set up PBO + Undervolting. I am trying to undervolt to max performance and clock speed and at the same time minimze temps I bought a 7900x, will arrive next week, but I wanted, for the first time, undervolt it instead of overclocking it. Welcome to the reddit community for Vampire Survivors. 7900x, 42 degrees idle (that's CTL, both CCDs are around 30-35 degrees) Single tower air cooler Stock - no undervolt, nothing For multicore chess calculation goes to 90 and above quite fast If it's above 50 idle i'd double check the cooler, or maybe something's running in the background Anyone have additional tweaks or resources they can point me to to mess around? 7950x w/ PBO undervolt by 100mv, 32gb DDR5-6000 EXPO CL30, Kraken X72 (without AM5 brackets), Gigabyte Master X670. CCD2 is stuck at 0 unfortunately. Mangaged -40 on the gold/silver cores and -37 on the rest on my 7600x. 011v) and limited the settings to the same as the 5950x, just to see how it would compare. So you may want to look at a per core undervolt. So, if I understood correctly "Eco Mode" is just a profile for the specific thermal and power targets for PBO. The boost is objectively for epeen since the power scaling is like 10% for like double the power. Those temps seem great for both CPU and GPU! Maybe a slight undervolt/voltage lock on GPU "will claim the 13600k is superior to the 7900x " Never seen anyone seriously making such a childish claim against a full-fledged 12-core 7900x regarding a full 6-core and some gimped 8-core-extra chip, still mfr'ed at 10 nano. 5% multi core @ same PPT with following changes: -45mv vcore offset. I can do about -13 on my 7900X without random stuttering/reboots. (YouTube has plenty of vids on this great little tool) it won’t be the absolute min max giga tuned option but it should make a substantial difference and it’s a simple click so why not. 6 GHz. Power limit 15%. 4 GHz and an overclock speed of 5. I don't see a dynamic vcore setting to offset the curve. Basically it can be set up at game-by-game basis if you wish (making performance profiles in drivers for them). just finished installing Windows10 Pro. Restored to defaults and time doesnt drift anymore. When i first bought the 7900x I was worried about the 95c temps during cinebench and the "low" average clock speed during the test. I have a 7700x and I went straight to -30 and had crashes. SoC voltage 1. com/spy/38493872. 6ghz max boost which seems ideal for this PPT. See photos for reference. These are liquid coolers which have a small puck that attaches over the CPU and is connected by flexible tubes to a radiator with fans that you mount somewhere else in your case. Not all chips can do -30. By manually using the curve optimizer (and power and thermal limit) we can fine tune those values to our particular silicon to potentially get better results than Eco Mode alone 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. Also, weirdly, RT titles did not stress the card harder than pure raster, but this is in terms of hitting instability from the undervolt. ) Gaming typically doesn't benefit from having as many cores as the 7900x has, although it's still a great gaming CPU. And when need it, stock it again. I still need a power supply, a cooler, and a case. Hello, I just purchase and bought Noctua NH-D15 chromax. Welcome to /r/AMD — the subreddit for all things AMD; come talk about Ryzen, Radeon… As far as i can tell if i set my 7900x in Eco mode 65w in Bios it will perform significantly worse than a 7900, about 15% in benchmarking at least, because you need to change other settings (effectively undervolt) too. I’m currently undervolting my CPU using PBO 2 in order to lower temps but have had no luck. I was able to get in on the microcenter bundle for the 7900x. I struggle to draw comparision between these two after undervolting. After some people said that it was boosting but limited by the heat and that was normal, I just kinda left it and didn't think much of it. In my 7700x core 1 and 5 are the preferred cores and can’t handle more than -10. The 7900X can seemingly get to 7900 "but 200mhz better", but it is difficult to compare to any X3D undervolt as I couldn't find much intel on that. 2-5. Darktide get unstable at any level of undervolt. However, if you’re looking for a more cost-effective option that still delivers excellent performance, especially in single-threaded tasks, the i7-14700K could be the way to go. I’ve been working on optimizing the perf/watt on my 7900x. Hey r/techsupport, hopefully you can help me out before I go buy an AIO. Coming from EVGA GM750 I'd say the Corsair SF1000L not much quieter than GM750, the fan spin up after 400w of load, and the noise is on par with GM750 of similar load. encoding, video editing, etc. I've had a Zotac 3090 and a 5800X on a Corsair SF750 platinum unit in this way, with zero problems. To undervolt safely you can download the ryzen master program and click the automatic curve optimizer and let it run on its own. Temp is 65c during gaming w/ 45% fan. The 7900x is faster in single core and mops the floor in multicore performance, no to mention bigger cache and better power management (thanks to being a 5nm chip. skill F5-6000j3038F16G 32GB T30 SSD Kingston KC3000 GPU 1080 EVGA FTW 3 Hibrid (i know I’ve tried to undervolt my 7900x to boost clock speeds to great success, however I’ve noticed diminishing returns happen before any instability issues.

I'm still trying to understand the nuances of modern overclocking (used to OC all my desktops, but not for 12+ years). I will choose after CPU because I have a limited budget but in the future I planning to upgrade the GPU of course if I buy RTX 3060 Ti I wanna upgrade to the RTX 3070 Ti or RTX 3080 :) We would like to show you a description here but the site won’t allow us. 775, but higher multi core scores and same single core scores. Even Optimum tech only managed -15 on his 7950X, and Level1Techs only managed -10 on his. My own 5900X (day 1 purchase), CCD1 can drop ~10-15. This is because the PPT (package power tracking) limits for the 170 W TDP processors is as high as 230 W, and for the 105 W TDP models, it's 130 W. Seemed disingenuous and lazy imo but that's why it helps to read multiple reviews. 99 price tag. I did a quick and dirty undervolt on the 7950x (0. Did a quick test on Ryzen 7900 with different PBO settings and Curve Optimizer and see how the performance scales and CPU temperature. Been like this for a few weeks and it’s great. Considering CPU temparature and Cinebench R23 performance, it looks 105W/125W Config TDP is good for my system. I also play on 3440x1440 (when supported of course). The SF750 on my other machine is a bit quieter than SF1000L. Edit: 'Idle Watts' and 'Cinebench Watts' are measured from the wall using a meter, and included the entire PC setup including two AW3418DW ultrawide monitors, usbhub, speakers, rtx3090, etc. (Asrock B650M PG Riptide). 6M subscribers in the Amd community. Still need to enable Expo and Eco Mode when I find proper videos. Feel free to ask any questions, start discussions, or just show off your runs! Min clock:2300 Max clock:3050 Undervolt: 1050 Memory clock: (108%, 2686 mhz) NO FAST TIMING, caused random instabilities. I wonder if anyone knows exactly what settings need to be changed to make them identical. I just set the undervolt to some random number and adjust until it doesn't crash. Basically, the 7900x has extra cores, which can be hugely beneficial for some productivity-related things, (ie. I'm wondering if this… CPU: RYZEN 9 7900X Motherboard: ASUS X670E-A BIOS Version: 0805 RAM: 64GB TridentZ RGB DDR5 6000MHZ CL36 Description of Original Problem: I have recently obtain 7900X combine with ASUS X670E-A.
