7950x3d undervolt reddit. 2V with DDR5 CL36 6000 MHZ ram (EXPO on) and noticed that lower VSOC voltages gives lower CPU temps. 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. Feb 27, 2023 · The Ryzen 9 7950X3D review is here, AMD is ready to take on Intel's mighty Raptor Lake. 42v is the stock boost voltage for MSI boards on 14th gen. 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. 42 and the next point is a stock 55x of 1. Prefer frequency option is bugged and doesn't work with PBO on, but it seems to not matter anyway. 285K subscribers in the overclocking community. I removed my -22 undervolt and turned off PBO. 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. My wife has the 7950x3d and for w/e reason, she gets way more fps in games that we play together. If you have one bad core that doesn't tolerate any undervolt, you're limiting the offset of all cores to that one core. Learn to overclock, ask experienced users… Here's a Reddit post about it from ten months ago, I've checked with the latest 1. The 7950X3D consumes about half the power as the 13900K under load and thus also produces much less heat. 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. I don't have much time for gaming so I don't want any nonsense when I get an opportunity. On average of 16 reviews, the Ryzen 9 7950X3D gain +3. My Cinebench score decreased by 200-300 points. You could always do the 13900f which is a slightly nerfed 13900k, but uses significantly less power. Thermals seems to have gotten better idle I'm around 39-42. 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. Jun 11, 2004 · Performance loss for watts saved seems to be much better for Ryzen's new chips. And no, you don't need to RMA. Most importantly, the games where the 7950x3d loses aren't by much and it's not game changing. 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. 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. 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. 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. Hello, since you are AMD employee, maybe you can help me. I want to ask about the stability of the system and how hassle-free is it. 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. The 7900x3d is pointless. The other 8 cores do not have the x3d cache, but they clock higher at 5. 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. But if I would get a consumer CPU then it would be the 7950X3D. I tried to replace thermal paste but it didn't help. As someone who favours productivity over gaming my gut says to go with the 13900K. 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. 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. 85ghz down to 5. The 7950x3d not only boost higher on the cache CCD but also has 32mb more of L3 cache. 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. 4V. 25ghz max. Efficency even beats the Ryzen 5000 chips on their watt-constrained platform. 20. But if you undervolt/power limit each chip, the 3Dvcache is still fine, so there is no need to drop the clocks as much. It also draws half the power (140W vs 282W) that the 14900K does - which means less heat, and therefore less noise. This means the clock speed delta between the 7950X3D and 7950X at the same PPT should shrink as you drop PPT more and more. TLDR; Page 1 : AMD has launched the $599 Ryzen 9 7900X3D, a 12-core CPU with a base clock of 4. 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. My current settings that are verified stable are stock + Enhancement 1, Core Flex preset, DOCP Tweaked, Core Boost enabled, and Medium Boostit enabled. 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. 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. Mainly by looking at the 5800x3d vs raptor lake. You can run a stress test all night then BSOD opening Chrome. 2ghz at its lowest speeds, and the ram kit is able to run at 6ghz just by turning on its expo profile. Normal instability issues when undervolting. Temps around 85c under cinebench r23 Working on a special SFF build and I decided to undervolt the 5800X3D. 011v) and limited the settings to the same as the 5950x, just to see how it would compare. 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. Stop using an all-core curve optimizer offset. 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. 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. 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. I’ve mounted and remounted both CPUs 5X each. 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. Aug 3, 2023 · VDDIO_MEM is the voltage that is used to transfer data from between the memory controller and the DIMMs. Actually using a negative 30 undervolt it's actually running at 5. Ignoring the recent SoC debacle. 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). The 7950x3d needs to be controlled by a driver, which may be a reason for the performance difference between the two CPUs. The issue is that 80% of people will use it stock for the life of the chip without changing anything. Passed a few months of mixed workloads and stability testing before I swapped over from x570 / 5800x. 4v), you hit instability because MSI decided that it will just mimic the value of 55x for 56x. My 7950x3d still boosts to max frequency on both cores quite often. Do it the hard way, and test each core using a per core offset. Which is why I found it pretty surprising. 7950x3D with a -10 negative on all cores (core 9 has a -5 offset). But then we also need to talk about power draw and heat. Also no OC/undervolt to CPU. The chip that runs hotter is way better silicon than the cooler running 7950X3D. By the way, tutorials specifically for 7900x3d I can't find, and I really wouldn't want to mess anything up. 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. 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. 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. 0. Everything is lightning fast and the difference is definitely noticeable. 7900x3d kinda doesn’t have a place in this is my point. 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. 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. . The problem is that 190w is still significantly more than the 120w rating of the 7950x3D. 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. Here are my specs: 7950x3d, Gigabyte Aorus Master B650E, Corsair 32GB DDR5 C30 6000mhz, Gigabyte Gaming 4090. Not every launch review shows the AMD processor in front, there are also counter-examples. AS01, go in Bios to: Advanced\AMD CBS\SMU Common Options and select CPPC Dynamic Preferred Cores to Cache. 95V will consume 100W+ less of power and produce less heat as well.

Ryzen 7950x3D . However. 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. 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. 6 GHz. Max clock went from 5. 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. My 7950x3d is very similar sort of ratio @ -30 and -15, except the top 2 non x3d cores at -5. 60 votes, 19 comments. But the 14700K is also less expensive so there is that to consider. 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. I'm currently running a manual VSOC of 1. You can cut system power draw but quite a bit. (Just a months later update, with the help of members and bios updates, everything is running nice. 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. I'm thinking about buying 7950X3D or 7950X and I want my pc build to be quiet. 4455 Megahertz ist the Max only singlecore spikes go to 4555. 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. Big thanks in advance. It seems that anytime I apply even a modest undervolt (-10), I get consistent bluescreens. This is absolutely a wait for benchmarks situation for the 7900/7950X3D. 7% over the Core i9-13900KS. 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. CO the 7950X3D if possible and undervolt the 4090. Get the Reddit app Scan this QR code to download the app now Undervolt it. I did a quick and dirty undervolt on the 7950x (0. In some cases, the 7800x3d is slightly faster than the 7950x3d.
