7900x3d undervolt reddit
7900x3d undervolt reddit. TL;DR: Lower PPT to reduce temperatures! For my ASRock B650E the settings are: Advanced > AMD CBS > SMU > PPT in mW set to 75000. They seem comparable, at least, but I know a lot of the video tests I've been watching (Hardware Canucks, Machines & More) use the L12 against the 7800x3d with great success, and according to some tests it's quieter and more effective than the is-55. 7% of the performance. Could you imagine if the compiler/scheduler could use the v-cache ccd in games that benefit from cache, and then use the 2nd ccd for games that don't benefit from cache but rather like high speed more. 121 votes, 114 comments. Darktide get unstable at any level of undervolt. AM5 boot times are long the first time you boot with new settings as it has to train the memory. By upping the power limit while limiting peak clocks, the core undervolt is always sufficient. Just wondering if anyone here here has had similar issues with the 7600, and has had success with undervolting? It seems like this cpu lost the silicon lottery if it can’t handle all core undervolt. Tried to undervolt and it still throttles . By the way, tutorials specifically for 7900x3d I can't find, and I really wouldn't want to mess anything up. If you undervolt the CPU it keeps the temperature lower and the CPU can therefore clock higher. 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 :) 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. Whats the best way to undervolt. My stability test was playing the game because of which I did the undervolt in the first place - it runs as described above. Should I Replace my AIO ? BTW it’s a AIO that’s only 2 months old . That's not necessarily a good thing. true. On my 3080, with a very simple undervolt i was able to shave ~100w of sustained power consumption with a very low loss of fps. 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. there are good enough aio's, but you'd spend less getting just a decent waterblock and some soft tubing to still beat the best of best aio's 7900x3d and 4070Ti are both a terrible picks though for the 7900x3d, either go all the way with a 7950x3d (best in both games and productivity), or get the regular 7900 (great in productivity) or a 7800x3d (best in games). However, AMD has The 7900x3D promises to be a top tier price/perf CPU over time. . I removed my -22 undervolt and turned off PBO. Jan 8, 2023 · This thread was created to serve as a meeting place to share thoughts, speculate, and theory-craft on the upcoming AMD Zen 4 Raphael-X 7XXXx3D chips: The Ryzen 7 7800X3D, Ryzen 9 7900X3D, and Ryzen 9 7950X3d. It has a low idle power usage, it’s not significantly slower than the 7800X3D in gaming (10% slower on average), an absolute beast in programming tasks due to its large amount of cores, and you can undervolt to significantly decrease the load power draw while losing very little performance. 40 votes, 45 comments. 5% multi core @ same PPT with following changes: -45mv vcore offset. Productivity speed is overrated. All things overclocking go here. Pricing wise, if you are concerned MSRP being abit 'high', then don't buy it right on release, but most in this price bracket, don't exactly care that much for couple hundred in total build cost. Everyone knows more heat = less performance, so it makes sense to undervolt 100%, but ONLY for the X3D versions if you want performance gain in addition to it. I am not saying Cinebench was a stability test - I was just benchmarking. Are there any specific features or items you want/need in the build? (ex: SSD, large amount of storage or a RAID setup, CUDA or OpenCL support, etc) Nope Writing from multiple independant threads can get a ~2x boost because the write connection to the CCD's is only 50% of the total bandwidth to the IMC and Mem, but the Read connection is 100% and only gets very slightly improved through reduced downtime/bubbling. It was 33,329 for a 10 minute test, though the single run scored higher at 36,673. TLDR; Page 1 : AMD has launched the $599 Ryzen 9 7900X3D, a 12-core CPU with a base clock of 4. My CPU kept using 142w untill I found and changed the same settings in another tab. SoC voltage 1. I recently upgraded my system and got: Msi Mpg x670e carbon wifi MB Ryzen 7900x3D cpu G. The whole point of negative PBO is to "make room" (in voltage) for more and longer-sustained overclocking, including via built-in mechanisms like Core Performance Boost (CPB). Rightnow I run my CPU perfectly stable at +200mhz and per core undervolting range from -6 to -30 Reply reply More replies My 7900x3d thermal throttles on cinebench despite having a corsair h100x 240mm aio . 8M subscribers in the Amd community. This being a DX11 game, the power saving is pretty optimal. The 7900x3d loses in literally every scenario to one of those aforementioned chips. 4 GHz and an overclock speed of 5. 152v or so, and it might be harder to undervolt aggressively. The memory controller slows down when you undervolt it, and since the VDDG voltages are derived from it, you also inherently must undervolt them ever further to hit the 40-75mV target distance between the steppings (SOC -> IOD -> CCD). 1. Just did a benchmark test and I know I can push my components quite harder and get better performance from them. I'm targeting the 7900X3D, and am very interested to see how it performs in reviews later this month. Welcome to /r/AMD — the subreddit for all things AMD; come talk about Ryzen, Radeon… I reported it here, on reddit, and surprisingly it been fixed. Also, weirdly, RT titles did not stress the card harder than pure raster, but this is in terms of hitting instability from the undervolt. it sounds like maybe you got bottom of the barrel silicon, or your motherboard's voltage regulation sucks ass. And now the 7800x3d still beats out the 7900x3d for gaming performance even with the good bit lower frequency. So that's a no go for 7900x3d, leaving it to be 7800x3d for strictly gaming, or 7950x3d for gaming and multitasking workloads, but the 7950x3d is way too expensive in my opinion. Hopefully they're just slow to update that list now that the 7800X3D is finally released, but I'd love to hear confirmation from someone who has actually plugged a 7800X3D into a B650 Aorus Thanks for the thorough reply! I will try this out when I have time. Keeping CCDs cooler (below 80C) generally helps stability when undervolting as heat increases internal resistances which needs voltage increases (or boost clock trimming) to Update 1: Improved to +1% single and -7. So i finished my build around 2 days ago and my 7900x3D reached 62°C max in cinebench r23 but stayed the most time between 60. Try using per core undervolt function. Min clock:2300 Max clock:3050 Undervolt: 1050 Memory clock: (108%, 2686 mhz) NO FAST TIMING, caused random instabilities. I knew there is similar bullshittery going on in the main hall of sanctuary, but i just don't care to record another report. AMD Ryzen™ 9 7900X3D With AMD V-Cache™ Technology. theres a reason theres guides to shutting cores off for some chips to improve thermals/gaming performance. I went in using hardware info I found out what the preferred cores were (there are 2) and applied a -10 undervolt. I have a 7700x and I went straight to -30 and had crashes. Mar 10, 2023 · AMD’s $599 12-core Ryzen 9 7900X3D is designed to take on Intel's Core i9-13900K, which it beats in gaming by 7% on average, proving it has the chops to take on Intel's finest. Confitur3 described it right. Highlighted bars show similar clock speeds and benchmark scores. Welcome to /r/AMD — the subreddit for all things AMD; come talk about Ryzen, Radeon… 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. 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). If this rig is for gaming, just get the 7800X3D. I agree if you don't care about finding the perfect undervolt then you can just leave it and it's probably fine depending on your cooler but as far as I know playing with undervolts is completely safe the only thing you risk is as you said instability which you can fix by changing it back to stock if needed. 0 and 60. The main way people seem to mitigate this is to go into the BIOS and set a negative curve in the PBO settings to undervolt the CPU which instantly can reduce temperatures. Game testing as of 5 December, 2022, by AMD Performance Labs using the following hardware: AMD Socket AM5 Reference Motherboard with AMD Ryzen™ 9 7950X, Ryzen™ 9 7950X3D and G. A 7950x3D is overly expensive, but also more advantageous. 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. But the biggest piece of the puzzle has been purchased, and will be here Wednesday. 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%. yeah, that's the thing with CO, intensive use usually won't tank the cores unless it's INCREDIBLY unstable (but in that case it probably will BSOD immediately upon boot into windows) but if it's a little unstable you can get away with stress tests but itll crash out idling haha. 08v. So I was a negative nancy the other day, reading reddit while waiting for my 7900X3D to come in, almost returned it before I even got it just because of the "why get that when a 7950 is only a little more" "just wait for the 7800X3D" while both are true, after installing my 7900X3D with no issues on a B650 Aorus Elite and installing all the chipset drivers, it works like a dream. Learn to overclock, ask experienced users your questions, boast your rock-stable, sky-high OC and help others! Thank you for your suggestion. Now compare the same two configurations in terms of average and max temperatures. Other chips of this series will not get any performance gains from what I've read and seen. Yes, you want these voltages as low as possible, but as high as necessary, especially when pushing speeds 3600+. skill 6000mhz 2x32gb ram And FORTUNATELY i had almost no time to test the system but i want to prevent getting bitten in the back by these exploding cpu issues so i have my system configured like this, Amd PBO set to thermal limit 75°C (i have extremely good airflow using noctua d15 dual fan and lots of I jus installed 7800x3d and playing around with the undervolt. Please help me to lighten up the situation and guide me on how to undervolt my CPU in the right way. Mostly because last time i had to convince people that my PC isn't complete, total garbage and what i on purpose locked my fps at 60 with smoothing enabled As mentioned prior and you did too, most won't need the 7950/7900x3d. 7900X3D still is a fantastic CPU for any task other than gaming. Mar 10, 2023 · You can also now undervolt the X3D chips using the Curve Optimizer that can be accessed either via the BIOS or Ryzen Master, with the latter also having a built-in auto-tuning feature that How to achieve lower temperature with undervolting and overclocking with every Ryzen 7000 – Zen 4 CPU and every CPU cooler – air coolers included. As for cpu/cooler as mentioned above, my take is that the result will depend on some factors. Forgot the name of the tab but it is the one before the That said, are you dead-set on the 7900X3D? It's kind of a worst-of-both-worlds CPU at its price point - worse than the 7800X3D at gaming because the 7900X3D only has 6 cores attached to the 3D V-cache, and worse than the 7900X non-3D in most production tasks because the 7900X3D has lower clocks. My 7950x3d still boosts to max frequency on both cores quite often. It really depends. if you buying intel's best, get a custom loop. A 7800x3D will flat out beat it in gaming. Not sure if my temps are good but whenever windows switch the game to v cache ccd, my temps range from 78 to 83. PBO boost override disabled. 7% over the Core i9-13900KS. I was trying to set a maximum wattage and the problem is that the CPU undervolt/overclock settings were visible under the 'advanced' tab and not all settings from there were actually being applied. If nvidia didn't aggressively ramp up the voltage of their gpu's to extract every last cent of performance, perf/watt would be way better. PBO curves, by themselves, are not really a power reduction mechanism even if they do nominally reduce idle draw a bit. Power limit max, custom fam curve to keep Hotspot below 78. 88 seemed to give best results. Highly recommend getting custom cables of the right length to make your life easier. I've found out that CCD0 (0,1,2,3,4,5) maxes out at -14 while CCD1(6,7,8,9,10,11) can handle -30It seems that all cores belonging to a CCD actually behave the same, I will try some find tuning to see if tehre is any real difference between the cores on CCD0 Standard PBO if available for the 7900x3D, undervolt on the GPU. 8°C - did full 10 min run. Welcome to /r/AMD — the subreddit for all things AMD; come talk about Ryzen, Radeon… The 7900X3D would want one of the medium/larger coolers, so pick a slim GPU to give yourself more room if you go that route. The highest I have been able to achieve on Intel i9-13980HX is in the MSI GE78HX with a hefty undervolt on P-Cores, E-Cores, and Ring/Cache. The whole process of Curve optimizer and stabilizing undervolt and Fmax is “Full Week”. However right now, it's priced too high for its value. Games are different and some may work at 1050, while some need 1120 of full 1150. 478 votes, 143 comments. Skill DDR5-6000C30 (F5-6000J3038F16GX2-TZ5N) with AMD EXPO™; ALL SYSTEMS configured with NXZT Kraken X63, open air test bench, GeForce 4090, Windows® 11, PCIe Puget Systems - AMD Ryzen 9 7900X3D and 7950X3D Content Creation Review The primary area where we found a notable difference between the 3D V-Cache processors was in thermals and power draw, where the X3D CPUs used around 30% less power and remained around 5-10 degrees Celsius cooler on our test benches. Been looking into it and I'm not too sure anymore. Only CPU watercooled 2x 360mm Radiator (Watercool Heatkiller S30) with each 3x Lian Li Unifan SL Inf@2100 rpm. Right now I have expo for ram enabled, no other tunes -30 all cores ppt to 88 all else auto I was reading on reddit that people recommend putting the ppt at 75, but this made my cinebench score much lower and also the boost clocks lower. Example: uncapped FPS here btw - just limiting core clock to 2500 does the trick. Just wanted to know if it's better to undervolt/overclock via BIOS or through the Ryzen Master app? Is the ASUS ROG Strix B760-I compatible with the 7900x3d? Rest of build: NR 200p Max, MSI 4080 Gaming X Trio, Cosair DDR5 32GB 6000Mhz, WD Black 4TB SN850X, Noctua NF-A12x25 case fans x 2, & Windows 11. 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 Yup, cause its unstable at any undervolt. Welcome to /r/AMD — the subreddit for all things AMD; come talk about Ryzen, Radeon, Zen4, RDNA3, EPYC, Threadripper, rumors, reviews, news and more. This was my assumption as well, but even on Gigabyte's own compatibility list it does not include the 7800X3D (but does include the 7900X3D and 7950X3D). I bought a 7900x, will arrive next week, but I wanted, for the first time, undervolt it instead of overclocking it. 4 to 5 degree reduction when setting a thermal limit. For those of you who do not like their x3d processors to run at 85+ degree temperatures, I've got a little trick for you to get peace of mind when running 100% loads on these chips. I have my mem clock on 2714 no fast timing, min freq 500 MHz, max +-3000 MHZ, +15 PL. Making the 7900x3d completely dead in my opinion. E. With 3D V-Cache in Zen 4, that CCD is already operating at a much lower voltage cap of 1. 6 GHz. 8% over the Core i9-13900K at gaming performance, and +2. Anyone serious about productivity software that can use multi-core effectively and doesn't care about gaming should get a 7950X and anyone serious about gaming and doesn't specifically need multi-core productivity should get 7800X3D. It gets around 4900mhz clock speed and starts throttling . yep, lots of cores on 1 chip generates allot of heat. Basically it can be set up at game-by-game basis if you wish (making performance profiles in drivers for them). My Cinebench score decreased by 200-300 points. Is there any good guide out there? Mar 31, 2023 · I noticed when playing a game tonight that the cpu temp was barely cresting the mid 60’s when before it would constantly be in the high 70’s, and my framerate was considerably lower in an area where it should’ve been much higher, so something wasn’t correct. Stability tests passed: 236 votes, 168 comments. If your productivity work is very time sensitive and you lose money because of slower speeds then go with the faster productivity CPU. g. Please help me to lighten up the situation and guide me on how to undervolt my CPU in the right way, I am really clueless I guess By the way, tutorials specifically for 7900x3d I can't find, and I really wouldn't want to mess anything up. Sep 16, 2023 · Also, no crashing like you can get with an undervolt and a -10% powerlimit, especially if you bump memory. It's mainly for temperature because this CPU is known to be hot. I tend to think that the x900 (7900X, 7900X3D, ) CPUs are a bad compromise. Not every launch review shows the AMD processor in front, there are also counter-examples. No-brainer to add a thermal limit: Reduces temps by 5°C, while maintaining 99. I'd say that the 7900x3D will probably end in that excellent sweet spot of below $500 top tier CPU, but that won't be for months. 7800x3d on 47mm cooler is definitely pushing it - but if your room is not hot and you get good silicon lottery for undervolting, then you will be ok, but don’t expect load temps <80c or idle <50c. For me the max stable undervolt was -25. On average of 16 reviews, the Ryzen 9 7950X3D gain +3. Will definitely be looking to OC/UV, as it has worked out quite well for my 6900XT. I thought AMD put out a chipset update that parked the 2nd ccd for 7900x3d and 7950x3d when gaming. If you go too low with the voltage it will make the system unstable so you have to find out how far you can undervolt your chip.
