7950x3d undervolt reddit. 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. 13900k is probably the best cpu when you combine productivity and gaming. I'm currently running a manual VSOC of 1. It seems that anytime I apply even a modest undervolt (-10), I get consistent bluescreens. I did a quick and dirty undervolt on the 7950x (0. View community ranking In the Top 5% of largest communities on Reddit. The new scores were 18674. 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. 88 seemed to give best results. 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. 85ghz down to 5. For my work with Adobe products, the speed and overall stability of the 7950X3D is a complete game-changer. Prefer frequency option is bugged and doesn't work with PBO on, but it seems to not matter anyway. 42 and the next point is a stock 55x of 1. Passed a few months of mixed workloads and stability testing before I swapped over from x570 / 5800x. 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. 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. 0. But then we also need to talk about power draw and heat. The 7950x3d not only boost higher on the cache CCD but also has 32mb more of L3 cache. 011v) and limited the settings to the same as the 5950x, just to see how it would compare. Big thanks in advance. 1. Stop using an all-core curve optimizer offset. I can't get my head around how I should set my voltages for my 7950x3D. 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. Since you play a few games and not a whole slew of them, the 7950x3D would give you both worlds and is power efficient (except idle I guess). Is that normal? I’m building a carry-on build with a 7950x and I plan to 65w eco mode and undervolt it until I stop traveling and throw in an AIO. AS01, go in Bios to: Advanced\AMD CBS\SMU Common Options and select CPPC Dynamic Preferred Cores to Cache. Here are my specs: 7950x3d, Gigabyte Aorus Master B650E, Corsair 32GB DDR5 C30 6000mhz, Gigabyte Gaming 4090. You could always do the 13900f which is a slightly nerfed 13900k, but uses significantly less power. 42v is the stock boost voltage for MSI boards on 14th gen. However. My wife has the 7950x3d and for w/e reason, she gets way more fps in games that we play together. I currently use the Threadripper 3970X, but it's primarily a workstation that I game on. 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. Temps around 85c under cinebench r23 Working on a special SFF build and I decided to undervolt the 5800X3D. In some cases, the 7800x3d is slightly faster than the 7950x3d. 8% over the Core i9-13900K at gaming performance, and +2. As for tuning, you can undervolt the CPU with Curve Optimizer and if necessary you can run it in Eco Mode or manually tune for a lower POT/TDC/EDC. Do it the hard way, and test each core using a per core offset. You can cut system power draw but quite a bit. 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. 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. . 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. TLDR; Page 1 : AMD has launched the $599 Ryzen 9 7900X3D, a 12-core CPU with a base clock of 4. 25ghz max. Learn to overclock, ask experienced users… Here's a Reddit post about it from ten months ago, I've checked with the latest 1. You'll hardly notice the difference in performance. All things overclocking go here. Actually using a negative 30 undervolt it's actually running at 5. The 7950x3d needs to be controlled by a driver, which may be a reason for the performance difference between the two CPUs. CO the 7950X3D if possible and undervolt the 4090. Most importantly, the games where the 7950x3d loses aren't by much and it's not game changing. I agree they are both great "gaming" CPUs but with some process lasso and tweaking, the 7950x3d beats the 7800x3d. As someone who favours productivity over gaming my gut says to go with the 13900K. 6 GHz. 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. 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. (Just a months later update, with the help of members and bios updates, everything is running nice. 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. Efficency even beats the Ryzen 5000 chips on their watt-constrained platform. You can run a stress test all night then BSOD opening Chrome. 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. 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. Skill 2x16 6000Mhz CL30 with Expo2 enabled and manually adjusted timings. 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. 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. Your current undervolt is unstable - adjust slightly and see if it helps during normal PC use. The other 8 cores do not have the x3d cache, but they clock higher at 5. We're still at least a year away from zen 5. 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. 20. 285K subscribers in the overclocking community. 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). 95V will consume 100W+ less of power and produce less heat as well. My Cinebench score decreased by 200-300 points. I'm thinking about buying 7950X3D or 7950X and I want my pc build to be quiet. 7950X3D B650E-I 64GB Trident Z5 Neo (6000MHz, CL30) 4TB FURY Renegade (Gen 4) EK 240 Basic AIO (NF-A12x15 + T30, PTM7950) 4090 FE Silverstone Extreme 850R SFX DreamBigByRay Custom Sleeved Cables (24pin - 140mm, CPU8pin - 245mm, 12VHPWR16pin - 245mm) Settings.

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. 7% over the Core i9-13900KS. Jun 11, 2004 · Performance loss for watts saved seems to be much better for Ryzen's new chips. 4455 Megahertz ist the Max only singlecore spikes go to 4555. The issue is that 80% of people will use it stock for the life of the chip without changing anything. 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. Get the Reddit app Scan this QR code to download the app now Undervolt it. This is absolutely a wait for benchmarks situation for the 7900/7950X3D. 7ghz The 3D cache ccd (cluster of 8 cores with the x3d vcache) will generally undervolt more than the other ccd Get the Reddit app Scan this QR code to download the app now Looking at skaterbenchs hwinfo screen when using PBO 7950x3d was at 5050 all core and one core With the price of the chip, plus the currently high price of am5 ITX with the enforced switch to ddr5 I feel anyone on an am4 motherboard the 5800x3d is a no brainer move if you are purely gaming focused, even a 7800x3d seems like it will be a substantial cost and only makes sense if you were planning to build a new system (although seeing some of the builds here I know price doesn't factor). This means the clock speed delta between the 7950X3D and 7950X at the same PPT should shrink as you drop PPT more and more. Aug 3, 2023 · VDDIO_MEM is the voltage that is used to transfer data from between the memory controller and the DIMMs. Mar 5, 2023 · AMD Ryzen 9 7950X3D: Integrated GPU Benchmarks, Overclocking and Test Setup Page 1: 3D V-Cache For The High End Page 2: AMD Ryzen 9 7950X3D: 2nd-Gen 3D V-Cache Tech, Latency Testing Page 3 It's not like you need or even want to run sustained multicore loads over 400w, use the current and power limits, undervolt, stability test one core at a time for the highest boost speeds, take advantage of different core frequencies with your best/worst cores, let it drop clocks and power when you launch some huge multicore load, let it fly at The best thing to do is undervolt. 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. 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%. And no, you don't need to RMA. Normal instability issues when undervolting. This is my current configuration: G. Feb 27, 2023 · The Ryzen 9 7950X3D review is here, AMD is ready to take on Intel's mighty Raptor Lake.

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. Also no OC/undervolt to CPU. 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. 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. 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. 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.

Can report back because there’s so little content on this. My current settings that are verified stable are stock + Enhancement 1, Core Flex preset, DOCP Tweaked, Core Boost enabled, and Medium Boostit enabled. You're falling into AMD's marketing trick of advertising base TDP instead of boost. 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. 7950x3D with a -10 negative on all cores (core 9 has a -5 offset). I don't have much time for gaming so I don't want any nonsense when I get an opportunity. 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. 7950x(7950x3d) is slightly worse in rendering and is superior in gaming. 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. It also draws half the power (140W vs 282W) that the 14900K does - which means less heat, and therefore less noise. 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. 775, but higher multi core scores and same single core scores. 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. 2ghz at its lowest speeds, and the ram kit is able to run at 6ghz just by turning on its expo profile. I tried to replace thermal paste but it didn't help. 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. On the hotter 7950X3D worst core is -35co, with best cores being -50co, where as the cooler 7950X3D it just likes all core -27co. But the 14700K is also less expensive so there is that to consider. Max clock went from 5. Mainly by looking at the 5800x3d vs raptor lake. My 7950x3d still boosts to max frequency on both cores quite often. 4V. 7900x3d kinda doesn’t have a place in this is my point. Everything is lightning fast and the difference is definitely noticeable. But if I would get a consumer CPU then it would be the 7950X3D. The temperature results remain very consistent. Which is why I found it pretty surprising. Thermals seems to have gotten better idle I'm around 39-42. The 4090 at 2715 Mhz and 0. You could use an X53 or IS-55 instead. I’ve mounted and remounted both CPUs 5X each. 2V with DDR5 CL36 6000 MHZ ram (EXPO on) and noticed that lower VSOC voltages gives lower CPU temps. If you have one bad core that doesn't tolerate any undervolt, you're limiting the offset of all cores to that one core. Hello, since you are AMD employee, maybe you can help me. 4v), you hit instability because MSI decided that it will just mimic the value of 55x for 56x. Make sure to stress test just like you would for an overclock. 4 GHz and an overclock speed of 5. 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. On average of 16 reviews, the Ryzen 9 7950X3D gain +3. We would like to show you a description here but the site won’t allow us. 60 votes, 19 comments. The problem is that 190w is still significantly more than the 120w rating of the 7950x3D. The chip that runs hotter is way better silicon than the cooler running 7950X3D. Meh I say. I want to ask about the stability of the system and how hassle-free is it. My 7950x3d is very similar sort of ratio @ -30 and -15, except the top 2 non x3d cores at -5. During gaming, i did notice a lot more fps but not as much as i thought. Hello, today I will walk you through how to set up the 7950X3D to have the best gaming performance! I have all my Bios settings, Ram timings, and Undervolt s The S300 supports up to 60mm CPU cooler height. 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. cltgajph cqjo vowhne wszdr xwvni fzca omvcv zkmv fog hsiqdsi
