7900x undervolt reddit. Adrenaline is fairly robust and can "survive" many problems. The 7800x3d is purely an 8-core CPU with 96MB v-cache, while the 7950x3d is an 8-core CPU with 96MB v-cache and an additional 8 cores with regular 32MB cache. These will be fun chips to tune for anyone with the interest and know-how. bagaget. I wouldn't expect major issues with cooling using an NH-D15, and you can always just set a more aggressive fan More than a year user of 5900x, recently started using it undervolted to 1. I see some info on the 7900xtx from a few months back, but I wonder if there’s a good resource out there where some enthusiasts have figured out a good starting point for the 7800xt for undervolting and OCing. CPU: AMD Ryzen 9 7900X. Title says it all, did I get a bad chip? My auto over clock runs at 3-3100 but undervolting has been a nightmare. Very well done video and not too long either. 22W of the 44W goes to the CPU. 7800x3D doesn't need a premium board to perform at its peak. Also, saw in a video of Linus, that you can "release" the capped tdp of the 7900 to perform near the 7900X version. If you notice any instability, change one value at a time. I get 55. No-Nefariousness956. Test using benchmarks, stress tests, games, apps, etc. 985v but the windows time is always drifting, getting late. The longer boost tends to be more beneficial for cpus vs aiming for top boost speed. So i recently bought a Rx 7900xtx (the xfx model) and its been great but i do have a few questions for undervolting because this is my first amd card. i just built my pc and the cpu is getting 63. I’ve been working on optimizing the perf/watt on my 7900x. This also results in about a 14-15% performance loss, but so did running the extreme UV method for the limited amount of time a game would run to get an fps reading. Undid the undervolt and that same game ran for hours. Currently running: 500MHz MIN frequency. Intel Core i9-12900K at 125W and 65W | Club386. Still running 73-74 C and all I have open is my browser. At stock, it might produce more heat than your cooler can remove. Minimum recommendet PSU for the reference RX 7900 XTX with 350W TGP/TDP is 800W PSU. Boots to 4. 0750 to 0. with that said, 5mv is joke, won't do much. Well, ryzen master is good for quick configuration, monitoring and testing, but from my experience, its better to reset bios after you are done with it and put all your settings directly in the bios. Same also for my gpu undervolt, ran every benchmark everyone said to try and test, some for hours, it was all good. Skill Trident Z5 RGB, 16GBx2, DDR5, 6000MHz, 36-36-36-96. However, I haven't noticed any changes to idle temperatures (50c), or boost 5. 5800X3D is 82,6%. 5v. AMD doesn't have boost power settings like Intel does (think PL1 and PL2). #amd #ryzen9 #7900x #pbo #eco #mode #power #limit #undervolt #undervolting #undervoltage 00:00 Intro00:11 Unboxing00:30 Board Build02:13 Bench Test System02: It's a decent board for its price. Welcome to /r/AMD — the subreddit for all things AMD; come talk about Ryzen, Radeon For example, an undervolt might help you get bPtter performance when squeezing every ounce of performance in Cinebench R23. Gets me more performance but I'm trying to either overclock or undervolted for more gaming performance, any tips? Guilty-Sector-1664. I'm happy I didn't buy 13600k yet. But it seems like the boost algorthmn is broken, stating if you lock the FPS it should naturally use less power even without an undervolt. 3Ghz again without going above 75@ under longer loads but decided to keep it more quiet. • • Edited. There's plenty evidence that a (mild) undervolt on the RTX 3090 drastically reduces the "peak" wattage it sometimes requires, which is what kills some GPU's and has shutdown or even killed many PSU's. OptimumTech's ryzen undervolting video showed him lowering the PPT/TDC/EDC to 180000/480000/640000 whereas overclock. 8% over the Core i9-13900K at gaming performance, and +2. 50v. If you want to give your CPU an easier time, you can also set a lower temp limit, or lower PBO limits. RAM never exceeds 37c. 38v to 1. Is that sufficient for the 7900x? At microcenter they were saying 360mm minimum. At the same time, only a few reviews show really big performance gains: Only 5 of 18 test series show a performance . 150 but with 0. The 7950x3d needs to be controlled by a driver, which may be a reason for the performance difference between the two CPUs. Undervolt a 7900 XTX with a Ryzen 5 5600? So, the main issue is that it's running kinda hot, GPU is fine but as soon as it begins to game the fans go NUTS, the CPU as well, they run like 85% to 90% fan speed under stress, the overal temperatures are 75°C under stress with fans at high speeds and 55°C to 65°C idle, i got a Taichi GPU, and idk You totally can do it. • 1 yr. If temps is your main problem I'd just set a CO curve and lower the temp limit* instead of messing around with settings that may really affect your stability. What are some of the best undervolt/OC settings for the RX 7900 XT (2x8 pin connectors) I recently bought the MERC 310 RX 7900 XT and I'm wondering about what the best settings for it are. David_Cabr20. RAM: G. Only reduce the power limits if your cooling system cannot handle the extra heat. They gathered data from 19 reviews from all over the world. 6. Hi,I tried to set negative offset for my R3900X and i think im good with - 0. If you feed it a decent kit of DDR5, and a CPU with good silicon, she performs well. 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. Meaning it consumes much more power & frequency than needed regardless of resolution. Ryzen 9 7900X running hot. I’ve tried as high as 3200mhz and as low as 2500. So the answer is 'yes'. The 12700 and 12700h are different. The main reason the 2500K was relevant for so long was because Intel CPUs barely got better for 5 generations, you could OC the snot out of it (power draw/thermals be damned!), and PS3/Xbox 360 ended up being the longest console generation thus far (so most developers didn't bother upgrading CPU requirements). So far the system has been stable with no crashes. And a few of the games I'll really be playing. I'm still trying to understand the nuances of modern overclocking (used to OC all my desktops, but not for 12+ years). Followed this and got to 16. Restored to defaults and time doesnt drift anymore. Skill 64GB DDR5 6000 CL30 (2X32) MSI 3090Ti Suprim X 24G Seasonic TX 1600 PSU. However, UV settings are very different for different games, some won't run stable with any amount of UV (like Darktide). 4. •. Ryzen master can conflict with bios settings. I’m targeting a 95W PPT with a boost override of -100 for a 5. Oct 5, 2022 · How to achieve lower temperature with undervolting and overclocking with every Ryzen 7000 – Zen 4 CPU and every CPU cooler – air coolers included. I plan to test going lower than -30 and see what is stable but I highly recommend doing it. Because you need to buy a z690 z790 board for the 13600k peak performance. Hey r/techsupport, hopefully you can help me out before I go buy an AIO. Followed a youtube guide to underclock to 4. Enable it then select "All Core" and "Negative" then put in 15. Overclocking definitely feels replaced by undervolting/power limiting/underclocking. Productivity is a touch better in the X variant, but again at much higher power consumption. For reference, my curve optimizer after extensive testing is -21, -8, -13, -21, -17, -10, -21, -21. 7% over the Core i9-13900KS. When the CPU is drawing its max 95W, the socket is drawing 120W. Setting a thermal limit will give you less for less power. Do not waste your time with PL1 at 65W. Rate me! You can try undervolting more I think. This tunin Also you can enable eco mode to keep it at 65w even under all core work loads. This works for all RTX 3000 and 4000 series cards, but the 3090 (Ti) is particularly guilty. 280 mm is quite close to 360 mm in terms of surface area. It's better to run 1100-1120mv and limit clicks to 2300-2400mhz. The 7900X already auto pushes itself as fast as your cooling will let it. Yeah undervolt and overclock for non x is the same Yes ofc you need a cooler that can move the heat but all of the big coolers will perform pretty much the same, at 95C. Last edited: Oct 21, 2023. 2ns with my below settings. Something like thermal grizzly Kryonaut would be good for thermal compound and aio, unfortunately,I do not have enough info to suggest one. Following the recent incidents where AM5 X3D CPU's got fried, allegedly due to too high voltage settings applied when enabling EXPO, it seems that some Motherboard manufactures have reacted already and silently released BIOS Any good resource on undervolting and OC/tweaking the 7800xt that a noob can follow? Overclocking. Ryzen 9 7900 undervolting. They are throwing everything the CPU has to offer to get all the performance out of these. All of the boost is included in the one current number. I added 2 additional 140mm fans to the case to exhaust. Basically in terms of raw performance it's about the same as Nitro+ but consumes less power. This is just a cap on performance and will not yield as good of results as undervolting. Ive limited my GPU to -10% though as for example in CP77 on 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. I'm using std EXPO timings/voltage on my Ram (Corsair DDR5-6000 [30]) and have successfully tested so far to -42 on all cores in curve optimizer (OCCT stability test - extreme - 3 hrs) and am 7900x high temps. Undervolting is a pitaand not really a game changerthe best uv i had was 1135 mv, but it wasn't stable in all gamesif you just want to lower the temps/ tjunc just do a repaste and hope Edit: Full System Specs: AMD Ryzen 7 7800X3D (PBO, CO -30) Asus X670E Hero G. Looking to keep temps under 60celcius. I struggle to draw comparision between these two after undervolting. 1-4. I use -10 offest on 4 cores and -12 on the best two cores. Played a game and ran fine for hours, then tried another game and it constantly crashes after every 5mins. Struggling to undervolt 7900xtx. xDoWnFaLL. 13500HX is maybe 10% faster than 12700H in multicore, but it also consumes more power. Ancient Gameplay has found that undervolting massive helps reduce power usage often by 70W on the XTX. Tried many more tests and basically had to turn the undervolt down more. LoserOtakuNerd. With 105w and CO, its more easy to maintain a steady clock and temp since its not being fully pushed. You will get better performance, but if you don't push the CPU to max and use it for daily, it be no different to a full 7900x since your not pushing it to the max. 40v (seems to depend on core). It's better than manually putting a negative voltage offset. It may reset the tuning, but the saved settings can be loaded again. V. Not every launch review shows the AMD processor in front, there are also counter-examples. Undervolted 7900x is okay but need gaming overclocking tips! I recently have a 7900x undervolted, running by core and have the most powerful cores boosting higher by reducing the power draw of the others. Undervolting my 7800X3D made my performance noticeably higher and my system run cooler. Many enjoy longer boosts with an undervolt vs an overclock which provides a shorter boost length at a faster speed. 5 to 70. By default, PBO2 wants to start CCD0 at a roughly 1. Plus x variant is now cheaper. OP's socket was being supplied 44W. Also the $140 price difference will also be lessened. AMD's official TDP/PPT/TDC/EDC #s for the 7950x/7900x are 170W/230W/160A/225A. net says to lower PPT/TDC/EDC to PPT 142,000 TDC 110,000 EDC 170000, which is wildly different from OptimumTech's. Some custom designs might have higher maximum TGP/TDP @ default settings but this will be mentioned on the Manufacturer website. Only assholes do that. GPU: MSI GeForce RTX 4080 SUPRIM X. 7Ghz, so on that chip yeah you might be losing 1GHz on low threaded work, but the performance impact is not something you could blind test convincingly. Quite well. 15 @4. I set a -30 offset on all cores and I bagged an extra 1000 points in Cinebench r23. Double or triple that immediately. 75ghz on the others. Rate me! : r/overclocking. That's how I'm running mine. Can't find that many posts or videos about it. 7900 is 65w CPU with same amount of cores and threads it will be more efficient choice. I run a 280 Rad though so you should get 4. undervolting is about getting more for less power. I looked at Armory Crate and saw that it's idling That's not necessarily a good thing. 823ghz on the good cores and 4. Sep 16, 2023 · Got a RX 7800 XT Pure and its stable @230w -10% Power Limit (1025mV) and also there is +2-3% performance increase over stock @255w. It seems no matter what I set the max clock to, I can’t go under 1110mv or I’m crashing. (Asrock B650M PG Riptide). Reply. 5 all core. 7900X close to a 7900 or, likewise, OC a 7900 to achieve 7900X power 851 votes, 331 comments. At this point, i don't know wheter to go to a 7900 or 7900X. -0. Just as with the 12900K and 5800X once your cooler is big enough for the volume of heat going bigger doesn’t get you better temps, because modern CPU are now made so much more compact than in the past. 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. Rx 7900xtx undervolting questions. 1Ghz, max temp is below 70C in 3d and video rendering. Considering CPU temparature and Cinebench R23 performance, it looks 105W/125W Config TDP is good for my system. Odd thing is, it ONLY happens when OCCT is open. 2 on a stock cooler all core with temps around 70'C. Average power usage is like 285w and your games don't crash. 2c idle when i tried to run fortnite it jumped to 95 and stayed there. and then it'll idle at like 58 C - 76 C. Probably best if you link in a screenshot. ADMIN MOD. I can get my 6700 XT to 1050 no problem. I started undervolting my 7800x3d and made it to -26 all core offset using bios curve optimizer and I started noticing this odd flickering when using OCCT cpu all core bench. 3. And when need it, stock it again. Same goes for an 7900X, it's a very good processor Basically the CPU will hit 95C, no matter the cooler. OCCT, HWiNFO, and CapFrameX are a great way to monitor the system. Best I can do is 28-2900mhz max at 1110 Im using Corsair RM750X (750W) with RX 7900XTX paired with R7 5800X and hadnt problem even with OC where my GPU used up to 450W (XFX Merc 310 7900XTX Black Edition which gives you maximum +15% Power Limit meanwhile models such as Red Devil by PowerColor give you up to +30% I think). BIOS Version: AMI UEFI 1. Computer Type: Desktop. Games that use an all core work load like The Finals sit at 4. Hunter422. It is stable also at 1. usually most 3900x, a negative offset will hurt single thread boost and increase multi thread boost since it will run cooler. The boost is objectively for epeen since the power scaling is like 10% for like double the power. What I’ve found so far is impressive undervolt capability. 47v max voltages, and as zen4 is very much "balls to the wall" it would not surprise me to see 1. Maybe start 15mv. Tuning and Undervolting my 6700xt . 7900x at a manual 105w eco mode is also really good. They are functionally identical CPUs when running with the same power limits, so you should just get the 7900. 7900X has base clock of 4. Tracker thread for AM5 Bios updates with voltage restrictions (to prevent X3D's frying) Overclocking. EDIT 2: Some suggested that my PBO CO offset was too aggressive for the 7800X3D, so I backed the under volt to -15 offset. Сooling system: DEEPCOOL AK620 ZERO DARK. Go to BIOS then Advanced>AMD Overclocking then Curve Optimizer. 150 pc was reseting short time after launch. The question of whether the 7800X3D + A620 chipset is inherently worth it comes down solely to AMD's featureset, in which case B650 and A620 are EXTREMELY similar: both PCIE 4. Now in Cinebench my scores are 7174 pts, with cores from 4100 to 4125 mhz (and temps dropped from 74 to 68-69 in C20) - is it good result? Take a look at the meta launch analysis from 3Dcenter. Performance per watt is increased, so temps should go down a bit in partial workloads only since the CPU doesn't have to work as hard--for example during a typical game load while the CPU is only being used 25-40%. Did a quick test on Ryzen 7900 with different PBO settings and Curve Optimizer and see how the performance scales and CPU temperature. Another review showing undervolting and/or power limits being hugely impactful in many workloads. You probably won't tell much difference in performance unless stress testing, and probably heat generation using PBO2. Cinebench r23 results are consistent between 20 and 21k score. ago. 100V is a _massive_ undervolt - if you get instability this is #1 suspect. Undervolting is very good for RX7900 since you can increase power limit at the same time and have a card with the same temps and faster performance. AMD Ryzen 9 7950X vs. And the CPU clocks go up as long as the CPU isn't getting any hotter and/or the CPU is not hitting power limit. Both 12700h and 13500hx are 6p-core+8 e-core (total 20 threads), but 13500hx can undervolt and the frequency is better than 12700h. Overclocking. PSU: DeepCool PX1000G, 1000W, 80+ Gold. Motherboard: ASRock X670E Steel Legend. SirGeorgington. As 125W + Curve Optimzer -30 applied, the Cinebench nT performance is close to stock Ryzen 7900X. In OP's case, the actual CPU was being supplied 22W. 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. Depends on the adaptability to efficiency you could get on a U. Archived post. The answer btw is that these are likely single core maxes (completely normal) - I can't talk for zen4 as I haven't worked with one yet, but on zen3 you can get 1. With my Ryzen 7700X, I am doing 6200mhz CL28-36-36-36-30 with tRFC @ 400, using 1. 1v I started from 0. 105w + a small undervolt is better than stock performance with temps around 75-80 at load depending on how aggressively I set my cooling fans. If it doesn't boot or keeps rebooting then put in "10", if it does so again then "5". I'm pretty sure 13500hx is better, 12700h isn't 8 p-core. Intel sets the thermal throttling temperature to 100°C. So now I have 2 140mm fans bringing air in and 2 Out, plus two on the radiator. 7800x3D performs way better at lower power consumption. is this fine? pretty sure thermal paste is fine, do I need a different cooler and if so which one probably at least a 240mm aio and a high-end thermal paste. Ryzen 9 7900X can't undervolt and running hot. Only 5 of these reviews measure average FPS! Average gaming performance of the 13700K is 94,2%, relative, compared to the 7800X3D at 100%. That would be as equal as useful. MuchRefrigerator7836. Some bios, SMU won't allow negative offset. On average of 16 reviews, the Ryzen 9 7950X3D gain +3. 1. 7900x is the second-best gaming CPU that AMD has made, so probably treat it with a high end cooler and thermal paste. 0, 32 vs 36 PCIE lanes, the only difference is CPU overclocking and a limit of 2 10gbps USB ports, no 20gbps ports. I first started with heaven benchmark and started to drop the voltage and it kept going at a moment it was pushing 3+GHz and went as low as 1010 mV. For what I understand they both can be adjusted to be one another, non x with pbo becomes x, x variant becomes non x with eco mode. 85W PPT is also really low, 142-170W would be the range for 5800X to 7700X. She makes the somewhat complicated new way of overclocking pretty straightforward and shows the performance results of each step. Just pulled the card (Powercolor Hellhound XTX, its a 2 x 8pin card) apart and re-pasted Power Limit causes the cpu to run slower with the default voltage curve, and possibly stuttering under spikes. 2700MHz MAX frequency. You should definitely use a 360mm over a 280mm unless you limit power draw by a pretty good amount. 065v @4. Seems like AMD is expecting fierce competition to these. Most people who have done even a bit of stability testing on their undervolt/overclock will find there’s a couple cores that need more voltage, but you think yolo -15 is magically stable. Not that bad this time. 7950x underclock undervolt. 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. Ryzen 3900X undervolting results. 6ghz max boost which seems ideal for this PPT. 8MHz and undervolt to 0. 21. 5k in port royal, stock was about the same as hers. Its better to use ryzen master or bios. Yeah I saw the minimum requirement earlier today. Set both power limits to at least 200W so these limits do not interfere with maximum performance. It needs over 100W for its performance. 6M subscribers in the Amd community. ylrbhrpxpliuelvqqolc
