7950x3d undervolt reddit. I'm thinking about buying 7950X3D or 7950X and I want my pc build to be quiet. May 13, 2023 · The only way to undervolt now is through the curve optimizer, but the way that works is a bit weird and it won't bring down the peak voltage, just the average voltage. Jun 11, 2004 · Performance loss for watts saved seems to be much better for Ryzen's new chips. You can cut system power draw but quite a bit. 7% over the Core i9-13900KS. Prefer frequency option is bugged and doesn't work with PBO on, but it seems to not matter anyway. I tried to replace thermal paste but it didn't help. The problem is that 190w is still significantly more than the 120w rating of the 7950x3D. I’ve mounted and remounted both CPUs 5X each. There's going to have to be some sort of software component needed for the CPU's to know what cores to allocate to what games to make sure games are loaded on the right CCD. Efficency even beats the Ryzen 5000 chips on their watt-constrained platform. Ryzen 7950x3D . ive been running -30 curve optimizer since the day i bought it (last 2 weeks ago) been playing warzone, left the pc on for 2 days because i was downloading games (on a 10mbs internet, its free intertnet in my apartment) seems to be stable, i never had a blue screen or random restart. It also draws half the power (140W vs 282W) that the 14900K does - which means less heat, and therefore less noise. 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. You can but it’s mostly meaningless because it’s gonna just boost within spec anyways, you want to undervolt it because the cache is so heat sensitive and it’ll push high frequency at the same voltage. I currently use the Threadripper 3970X, but it's primarily a workstation that I game on. 13900k is probably the best cpu when you combine productivity and gaming. This means the clock speed delta between the 7950X3D and 7950X at the same PPT should shrink as you drop PPT more and more. The other 8 cores do not have the x3d cache, but they clock higher at 5. 4 GHz and an overclock speed of 5. This is absolutely a wait for benchmarks situation for the 7900/7950X3D. 85ghz down to 5. Then I won't have problems with the E-cores and P-cores, and the 7950X3D has 16 equal cores over 8 P-cores the Intel has, not to mention, even a Threadripper is easier to cool than an Intel CPU. 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. My 7950x3d is very similar sort of ratio @ -30 and -15, except the top 2 non x3d cores at -5. My current settings that are verified stable are stock + Enhancement 1, Core Flex preset, DOCP Tweaked, Core Boost enabled, and Medium Boostit enabled. 4455 Megahertz ist the Max only singlecore spikes go to 4555. Temps are usually around 50 c in idle, 79 c in cinebench and can go up to 87 during shader compilation in The Last of Us for example. If you want to get a power efficient gaming cpu, the answer is same as last gen, the 8 core x3D part, so the 7800x3d. 20. Here are my specs: 7950x3d, Gigabyte Aorus Master B650E, Corsair 32GB DDR5 C30 6000mhz, Gigabyte Gaming 4090. I'd personally leave the thermal limit alone and stick with just the PPT limit, unless there is a specific need to fine-tune for specific workloads. I have a per core undervolt on the first ccd of -30 and I was wondering what VSOC's you guys use and what's the cons are of going too low. 60 votes, 19 comments. But then we also need to talk about power draw and heat. View community ranking In the Top 5% of largest communities on Reddit. Can report back because there’s so little content on this. And no, you don't need to RMA. By spec, it is supposed to be set to the same value as the DRAM_VDD/VDDQ voltages, so it should in theory be safe up to 1. Are These Normal Temps For 7950x3d Under Stress Test? many people use PBO to undervolt -20 Most of the games I'm most interested in seem to prefer the 7950X3D Starfield being the only outlier. My wife has the 7950x3d and for w/e reason, she gets way more fps in games that we play together. By the way, tutorials specifically for 7900x3d I can't find, and I really wouldn't want to mess anything up. You could always do the 13900f which is a slightly nerfed 13900k, but uses significantly less power. Looks like benchmarks show significant multi thread speed reduction but almost no reduction in single threaded/gaming application Where I live the pricing only really favors either 7800X3D or 7900X3D, as these are only ~50USD apart, while reaching for 7950X3D is another 250 USD extra, which definitly doesn't make sense at this point. I did a quick and dirty undervolt on the 7950x (0. Also no OC/undervolt to CPU. It is not efficient (undervolt could help??), and runs hot (this is by design so don't worry about it), but quite good at your workload 7950x3d is a weird cpu and if it fails to use the right cores for gaming you will have issues with performance. The 7900x3d is pointless. So for current Ryzen generation, get a 7800x3d or 7950x3d. Bringing the latest upgrades to the Ryzen 7000 "Zen 4" family, this processor rocks 3D Vertical Cache technology along with a massive 16-core/32-thread count, and its makers claim that it levels up to the Core i9-13900K both in gaming and multi-threaded productivity, making it the most powerful desktop Edit: temporary solution for 7950X3D owners until Asrock will fix it again or will reimplent what was working in 1. 285K subscribers in the overclocking community. 95V will consume 100W+ less of power and produce less heat as well. Mainly by looking at the 5800x3d vs raptor lake. Temps around 85c under cinebench r23 Working on a special SFF build and I decided to undervolt the 5800X3D. CO the 7950X3D if possible and undervolt the 4090. But the 14700K is also less expensive so there is that to consider. For my work with Adobe products, the speed and overall stability of the 7950X3D is a complete game-changer. 8% over the Core i9-13900K at gaming performance, and +2. 4v), you hit instability because MSI decided that it will just mimic the value of 55x for 56x. I will use 360 Pure Loop 2 FX with 6 Noctua's NFA12-x25 (push pull) mounted as front intake (wanna run noctua's at around 1000RPM). You're falling into AMD's marketing trick of advertising base TDP instead of boost. Course, the Raptor is right around the 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.

You'll hardly notice the difference in performance. D= I think i've tried all the videos everyone recommended in this post lol Given your needs, I would recommend 14700K, 7950x3D, and 7950x. The temperature results remain very consistent. 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. 42 and the next point is a stock 55x of 1. Skill 2x16 6000Mhz CL30 with Expo2 enabled and manually adjusted timings. 7950X3D is a 168W PPT value, so it's only 12% less power than a 190W-limited Intel chip, but it sounds great because hey, 120W is a lot less than 190W! 7950X3D is king in low latency DAW benchmarks. Thermals seems to have gotten better idle I'm around 39-42. I know it’s been done before but I’m just astounded at the extra performance with lower temps (using the AXP90-X47 with the Noctua NF-A9x14) Start at -10 and work your way down. All things overclocking go here. Most importantly, the games where the 7950x3d loses aren't by much and it's not game changing. The 7950x3d needs to be controlled by a driver, which may be a reason for the performance difference between the two CPUs. CPU (PBO2 -20 all core undervolt) The fan sometimes get too loud (even when I'm just on reddit) for a few seconds and then goes back to normal. 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 don't use buffer sizes larger than 128 as there's a noticeable input delay, so the X3D was the right choice fo rme. (Just a months later update, with the help of members and bios updates, everything is running nice. If you have one bad core that doesn't tolerate any undervolt, you're limiting the offset of all cores to that one core. We would like to show you a description here but the site won’t allow us. However. Passed a few months of mixed workloads and stability testing before I swapped over from x570 / 5800x. Do it the hard way, and test each core using a per core offset. But if I would get a consumer CPU then it would be the 7950X3D. 6 GHz.

Setting a by-core offset in your v/f gets fucky on MSI boards because if the boost clock point is dropped below the stock voltage for any point below (which is very, very easy to do when stock 56x is 1. I'm currently running a manual VSOC of 1. The games where the 7950x3d wins by a lot, it is game changing and those games aren't likely to be reflected all that much in most reviews. Aug 3, 2023 · VDDIO_MEM is the voltage that is used to transfer data from between the memory controller and the DIMMs. This CPU is niche Please help me to lighten up the situation and guide me on how to undervolt my CPU in the right way. 42v is the stock boost voltage for MSI boards on 14th gen. 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. But if you undervolt/power limit each chip, the 3Dvcache is still fine, so there is no need to drop the clocks as much. The 4090 at 2715 Mhz and 0. Despite having performed all the various driver updates and activating DOCP (limiting my RAM to 6000Mhz since my MOBA doesn't support 6400), I noticed that the in-game performance was scuffed with a variable framerate and non-linear frametime. The 7950x3d not only boost higher on the cache CCD but also has 32mb more of L3 cache. As someone who favours productivity over gaming my gut says to go with the 13900K. My Cinebench score decreased by 200-300 points. Feb 27, 2023 · The Ryzen 9 7950X3D review is here, AMD is ready to take on Intel's mighty Raptor Lake. I removed my -22 undervolt and turned off PBO. It seems that anytime I apply even a modest undervolt (-10), I get consistent bluescreens. my guess is due to small amounts of 7950x3d being sold these So, i think i found solution how to test CCD0 Cache on my 7950x3d: check every core separately in aida64, y-cruncher N64 until there are freezes, bsods, reboots check 2 best cores together in aida64 CPU SHA3 until there are freezes, bsods, reboots (for me it's 1,3 cores) or check cores in pairs like 0+1, 2+3 etc. During gaming, i did notice a lot more fps but not as much as i thought. My 7950x3d still boosts to max frequency on both cores quite often. Could undervolt aswell if you’d like or apply a capped cpu temp on it so it I am planning a 7950x3d ITX build with MSI B650I edge and 2 sticks of 32GBx2 6000hmz RAM. . The one difference is if you allow the cpu to down clock at idle the more you undervolt the more chance you can run into idle stability issues from low voltage. Which is why I found it pretty surprising. On average of 16 reviews, the Ryzen 9 7950X3D gain +3. 011v) and limited the settings to the same as the 5950x, just to see how it would compare. The issue is that 80% of people will use it stock for the life of the chip without changing anything. Everything is lightning fast and the difference is definitely noticeable. 88 seemed to give best results. You could use an X53 or IS-55 instead. The chip that runs hotter is way better silicon than the cooler running 7950X3D. 2a AGESA and it is still broken:PSA - AM5's CPPC Preferred Cores (and thus all multi-CCX and vcache scheduling) is broken when using FO (PBO2 frequency override/offset) Welcome to /r/AMD — the subreddit for all things AMD; come talk about Ryzen, Radeon, Zen4, RDNA3, EPYC, Threadripper, rumors, reviews, news and more. 0. The new scores were 18674. 775, but higher multi core scores and same single core scores. On the hotter 7950X3D worst core is -35co, with best cores being -50co, where as the cooler 7950X3D it just likes all core -27co. 25ghz max. No the 7900x3d is a pointless cpu for example 7950x3d is better in both gaming and productivity, the 7800x3d is better in gaming and really close to the 7900x3d in productivity. In some cases, the 7800x3d is slightly faster than the 7950x3d. You can run a stress test all night then BSOD opening Chrome. Meh I say. 7950x3D with a -10 negative on all cores (core 9 has a -5 offset). I am currently on AMD Ryzen 2600 with MSI B450I , Where I faced a few stability issues like sleep mode not working, I jus installed 7800x3d and playing around with the undervolt. At stock settings it already consumes as much power as the 7950x in Eco mode, so I don't know how much more power you want to save. The default infra-limits for a 7950X3D (120W TDP) are: - 162W PPT - 120A TDC - 180A EDC - 89°C tCTL The official Eco-mode(s) operate by adjusting the PPT, TDC and EDC limits. If you do that route, you basically have a 24 core 7950x as the nerfing of it would make it match the 7950x(3d) in rendering, but then the 7950x(3d) would own the 13900f in 1. 1. I can't get my head around how I should set my voltages for my 7950x3D. I agree they are both great "gaming" CPUs but with some process lasso and tweaking, the 7950x3d beats the 7800x3d. Make sure to stress test just like you would for an overclock. 4V. Also to answer your other question, you can disable cores in the BIOS but it'll likely be less efficient than As such, I am eyeing the 7950x3d and have a few questions about it as all this talk about setting it up honestly seems daunting VS the simplicity of (from what I heard and understand) the one-and-done setup with the 7800x3d. Stop using an all-core curve optimizer offset. The 7950X3D consumes about half the power as the 13900K under load and thus also produces much less heat. apdy qdt bhamxfjt grhwd amvasn akrm jdnvjz kdfl vgs iopz  »
