7950x3d not boosting Without core boost you'll end up with a cooler CPU and lose 5-10% of relative performance. 43 on my 7900X3D, ive My 7950x3D has never even come close to the boost frequency. Other values, such as tFAW and tREFI also likely have room to improve. to pass that test I need to use a CO of-10 on the first 8 cores and I can use-26 on the last 8 cores pretty satisfied by the result The cache on top limits the boost clock. 6 and memtest at 5. So, it’s one core that just does not like boosting past 5000mhz. 23V (after Vdroop). The only thing setting me back is scheduler issues and possibility of having a shorter support lifespan because of potential issues 7900X3D Low Power Draw and Not Boosting Just built a new system and I cannot figure out why my 7900X3D will not boost under 100% load (all cores stuck around 4. 7GHz in single threaded tasks but on start up it boosts to 4. In some cases, a handful of cores may not even be capable of reaching those speeds (while this is for Zen 2 and not Zen 3, I don't imagine AMD having changed their manufacturing methods to ensure all cores can turbo up to the advertised speeds). Not sure if this suppose to happen since I saw others use optimizer with 7950x3d. lol. Hello, I have an Asus 670E Proart Creator Wifi with a 7950X. The C-State Boost Limiter prev If you haven’t enabled PBO that might explain why you’re not boosting as high. So got fed up, and took advantage of the MC extended warranty to swap my board, CPU, and cooler to an Asus X670E-E WiFi and a 7950x3D. Re-updated bios seems to have gained me another 200-300 jump, gained about 15 fps from benchmark, but still not hitting the boost clocks, so weird. 7GHz, even with PBO enabled and the +200MHz offset. 7 GHz regardless of load. Discussion I have an Asus B650E-F board with 7950x3D and I am NOT seeing this. to no avail. So far the rig is amazing - came right up, hasn't had a glitch or an issue. literally no difference in performance in games vs 7950x3d. When I run standard flat games, CCD1 is parked as expected, and everything runs smoothly. The PC did fine in all these tests and did not show anything out of the ordinary. The 7950X3D will feature an additional 4MB of L1/L2 cache alongside a peak single-core boost of 5. Bad for scoring but necessary for your CPUs lifespan When that's done, and if the temperature actually gets into a cooler state. 2 or 5. Skill 2x32GB 6000 GPU: EVGA GEFORCE GTX 1080 CPU Cooler: NZXT Kraken 360 Cooling Setup: 2 Noctua NF-A14 PWM Intakes on Top 1 Noctua NF-A12 PWM Exhaust In Back NZXT 360mm Radiator In I just got a 7950x3d and put it in an 11 litre case. 43. With a manual voltage setting, the CPU won't boost, it'll just run at the base clock of 4. You see, by default, the V-Cache die on the Ryzen 9 7950X3D, and 7900X3D comes with a lower boost clock than the vanilla Zen 4 die due to thermal restraints. Also 1. 2ghz all core where as the 7800x3d caps at 5. 5800x3d is not actually a 4. The closest I got was 5. While this offers better performance in light workloads, the Problem 1: 7950X3D is ignoring "Prefer Frequency" in Win11 and Win10 and tasks go to CCD0! But this happens when PC just sits without anything large to work on. 105 eCLK -100 fmax PBO Enhanced Level 1 90c, scalar x6, LLC 8, no CO and it was almost fully stable boosting up to 5197 but again SHA3 killed it. 5ghz. 2 GHz. But looking at HWInfo, i do see 5250mhz, or sometimes 5299 (im sure this is a reporting error) cause the max fused boost clock is 5250 for the vcache cores. Already did their latest bios update. The new Ryzen™ 9 7950X3D and Ryzen™ 9 7900X3D are the fastest gaming processors in the world and offer top-tier performance for content creation. 7-4. A premium air cooler like the Noctua NH-D15 is recommended at a minimum. If I use PBO2 it'll sometimes say in Ryzen master max boost is 5050mhz, But not boost past 4200mhz. I'm not able to boot at -20 or -30. The Ryzen 9 7900X3D will have a base and boost clock of 4. I sorta fill that niche for productivity, but more in the gaming crowd. Updating to win 11 fresh is my last hope rn. The issue is that 80% of people will use it stock for the life of the chip without changing anything. 850Ghz all the time. 6GHz, respectively. Using curve optimiser can squeeze a bit extra out of it. I swear some Ryzen CPUs are just funny about frequency. I agree they are both great "gaming" CPUs but with some process lasso and tweaking, the 7950x3d beats the 7800x3d. Why is that? ScatterBencher has overclocked the new Ryzen 9 7950X3D to 5. The cache ccd tolerates higher negative offsets than the frequency ccd. I'm especially interested in whether or not the 7900X3D will have a 6+6 for sure, which means they can bin better ccd'd for 7950x3d. Edit: Also, in addition to making sure the thermals are ok, I'd like to be able to turn down the fans a bit. But I'm on a 7950x3d on a 360mm set to full speed If PBO is off, the chip won't boost to 5050Mhz. I noticed this now in a few games. F5 Although if I adjusted the PBO curve to +20 all cores it would boot (although still WHEA after awhile) and the single core boost hit around 4600. The single core boost, on the other hand, can hit up 5. With per-core CO, the picture changes dramatically, as per earlier post with effective clocks. cpu-z shows a max of 5. but they forget the avg game performance difference is also %3 between the 7950x3d and 13900k lol. 3 ghz. As fast as the 4090 and XTX are, they should both be significantly bottlenecking the 7950X3D, not the other I was so eagerly anticipating buying a colossal 7950x3D, not having to deal with e core BS, just 16 monster cores boosted with tons of extra cache. 6ghz with 60 to 70 degrees, all core 5. This is kind of a pain in the ass procedure because it can be hours between crashes. Without multiple parts to swap out it might be hard to determine which. If I run CCD0 Core 1,2,3,4,5,6,7 Worth checking in case boosting is being masked by thermal throttling due to obscure fan powerplan settings that you may not have noticed. Spec: AMD 7950x3D (Latest chipset drivers 20/04/2023) Hi all, I'm noticed on my 7950x3d that my ccd 0 (VCache CCD) isn't boosting to 5. Apparently, there are suppose to be some optimizations through Windows 11. 3GHz all core, not nearly what mine is capable of. 2Ghz/5. Tried While you are correct, another issue is that the latest AGESA limits boost clocks for 4+ cores to 5. i don't often see it hit 5. üNDT³z !ÃÜ fiþ=— "UW¤* ~ظõX Ù gýëª ÉG _ ƒ š=üŸrËÿ¿×R@œ † H/0,a>A @·ðU\g\g\j¹÷¾÷¾žþÿ™ÕhºF³Ö®åÚ. 1ghz at 85 degrees, I can overclock to 5. 35V is low enough that you shouldn't burn up under a 12-core Also, I didn't care of the +25MHz that you can get with PBO Max Boost on the 7950X3D CCX2, because as you said it disables the AMD 3D VCache Optimizer Driver. Thread starter RanceJustice; Start date Jul 17, 2024; Jul 17, 2024 but it can be difficult to tell which options give the greatest performance increase up to the point of massive diminishing I understand that multi-core load should not boost to the max - I get about 4800Mhz on all-core load. Use the correct one in this folder for your power profile and disable that use driver setting in the bios, this works brilliantly, im not the creator, but he fixed core parking and somehow managed to allow cores to boost slightly higher, im using AMD Ryzen™ [Zen4-3D-2CCD] Ultimate HighPower 11-v5-Backup-2023. I can push it to 5500 This means that the CCD now thermally behaves like a regular Zen 5 CCD; and for this reason, not only will the CCD with 3D V-Cache on the 9950X3D/9900X3D have the same clock speeds and boosting behavior as the one without 3D V-Cache; but also the 9950X3D and 9900X3D are expected to ship with similar, if not identical clock speeds to the 9950X I'm not sure why I can't get this CPU to boost? XpanD. But a single-core load should be boosting to the max, that's what my previous 5800X did. 2GHz and then 2 seconds later it drops to 3. 7GHz on core 1 for short bursts only. Looking at skaterbenchs hwinfo screen when using PBO 7950x3d was at 5050 all core and one core spiking to 5250. When benchmarking single core it does not go much higher than 4. My system is fully updated (BIOS, chipset drivers, Windows 11 Pro (fresh installed), Game Bar, and Game Mode is enabled. Dear customers, please be informed that we will be closed on 25/12/24 (Wed) in celebration of Christmas Day. 29. best i can tell, all-core boost is maxed at 4. They were able to squeeze an extra 250mhz because thats just what it decided to boost to without the other CCD active. 250 GHz Core 1: -12 5. 1 To ensure an easy installation and proper operation of your system with a new Ryzen™ 9 7000X3D Series processor, please reference the step-by-step guide listed below. I don't get it. 8-6. 78GHz permanently and gets stuck Table of contents. I only use Process Excuse me Does anyone’s 7950X3D have a higher frequency of CCD0 than CCD1 when running software like R23 or R24? This is the case with my 7950X3D. I just did a cinebench R23 on it and the clock stays at 4. If I run CCD0 Core 1,2,3,4,5,6,7 I was not wrong when stating the C-State Boost Limit was not present with the hardware and BIOSes available at launch. Motherboard: ASUS ROG Strix X670E-A. The word "sloppy" falls short of this debacle. 3 Well, it’s complicated because how the boosting algorithm works on these CPUS, by limiting the boost clock you can put a higher offset because you will never boost over the offset and this works for SHA3, but most benchmarks will not even boost close to the max of the CPU, but SHA3 does for some unknown reason hence the reason for the BSOD. This new line of 3D V-Cache processors now features 12- and 16-core variants and does not have a reduced maximum boost clock. If I run CCD0 Core 1,2,3,4,5,6,7 Up to date guidance for optimizing a 7950X3D - PBO/overclocking, correct core behavior, and other performance tweaks ; expected temps, tools, more. Multi-core boost is lower. RAM: 4x32gb Corsair Vengeance DDR5-5200 (DOCP disabled because it won't POST enabled) And it does not boost to around 4GHz all cores, like it's boosting in all the various reviews, it's stuck at 3. So it's not thermally limited or anything. And the CCD0 boosts also up to a weird "wall" at 4. It is the same chip. All benchmarks lost 5-10% in performance. Now it wont boost higher than 5. A Lastly I activated Precision Boost Overdrive on AMD Ryzen Master which allowed my Single Core Clocks to reach the 4. 05 GHz (because AMD artificially limited its clocks that way). I seek perfect stability it seems that the heaviest test on this CPU is the SHA3 from Aida64. F5 Need some help. Following cause I'm still experiencing the same nonsense with my 7950x3d. However, some CPUs may be able to achieve higher clock speeds through manual overclocking. 2/4. When running. If your temps are normal.

But a single-core load should be boosting to the max, that's what my previous I used to own a 5800x3d and with PBOtuner I was able to get a -30 curve and was able to constantly boost to 4. 75 when I reset the bios. Temperature is 61C under full load. I'm on a MSI X670E Hi all, I'm noticed on my 7950x3d that my ccd 0 (VCache CCD) isn't boosting to 5. 7950x3d have large L3 cache that can boost single thread game to 20% or more when game is not gpu bound The total heat for 7950x3d is not that high, like 140w in cinebench or 60w in gaming. 2ghz no matter what. You could have a single core out of 16 set slightly too high, and that core might not pass that threshold and cause a crash for hours, then suddenly it does. check every core separately in aida64, y-cruncher N64 until there are freezes, bsods, reboots All 100% workloads are not the same with regards to boost and temps. To fully utilize the 7000X3D processors, you must update your mainboard’s BIOS to the newest one supporting 7000X3D processors and install the latest AMD It is normal for the Ryzen 7 7800X3D to have a boost clock of 4. 5-3. 5800x3D not boosting high after BIOS update Had 6 different intel 14900K and 14900KS chips which would not stabilize, each died in it's own spectacular way over time. reboot after like 20 runs even tho it passed FPU Julia, Cinebench, Y-Cruncher, CoreCycler (Prime95 non avx smallest) and many other tests. Not clear why, because even the 7950x3d is losing performance despite safety being better than stock (lower current, voltage and temperature all at the same time). Mind you, 7950x3D has higher clocks for x3d die than 7800x3d so you can have some gaming perfomance increase while you're at it. However with the 7950x3d I'm getting between 4. 1ghz single core either. 7ghz, roughly 5. Well, there goes my plans to buy an AM5 platform and a 7900X3D. Hence you can boost to 5. Guess I'll The Intel system is far easier to get RAM stable and overclocked on. as #1 I'm not boosting to 5. And I shouldn't need to activate PBO to achieve the expected clocks 7950x3d MSI x670 Meg Ace Mobo 4x 16GB G. Don't use all core though as it's just not very good for the 7950x3d (or the 7900x3d). It doesn't run into thermal or power limits. The precise settings for each of AMD's TDP numbers are above; note that a "120 W" TDP can As a quick refresher, the Ryzen 9 7950X has a remarkably high base clock speed (4. The reasons are obvious: Thanks to the 3D V-Cache, the voltage and thus the clock frequency are limited in order to protect the hardware from damage. Ones where the cache-only CCD still performs way better than most, but the game probably just can actually use >8 cores or something. Boost Clock Up to 5. this is why i kinda miss intel, ryzen cpu's try to be too "smart" and do all these backend adjustments According to Skatterbencher, negative boost clock override works on the VCache CCD, just not positive boost clock override on that CCD. The cpu is watercooled, and cpu temp never goes above 86c even after 12 hours of cpu stress testing. 7 GHz on a core that has no fast access to extra cache, or you can run on core that has more cache but won't boost as high (but still a bit higher than 7800x3d). Not a good thing for something that was sold to us as a finished product. 25 GHz in games, whereas the 7800X3D will top out at 5. 1ghz but now for some reason no matter what I play with in the BIOS my clocks wont boost past 5. AGESA 1003 re-introduces the Precision Boost C-State Boost Limiter, which was not present on the launch motherboards & BIOSes. With pbo enabled in both places in the bios the cores will not boost past 4. I assume this boost a bit better than the 7800x3d and leave ccd's with a couple of bad cores they can turn off for the 7900x3d. The 7800X3D must be binned differently then the 7950X3D CCD0; on isolated single core without CO, at least some cores in CCD0 of the 7950X3D hit 5200 and, the rest distributed still well above 5 giggles. This is because that problem core just might not have a reason to try boosting really high. I have the latest AMD chipset driver 5. This article deals exclusively with special benchmarks for the AMD Ryzen 9 7950X3D. To clarify first I'm using W1zzard's settings from his techpowerup review of rthe 7950x3d to try to get my CPU to consistently boost to 7950x3d. Looks alright, 95C is max boost temp. And that, too a relatively lower upper limit. Skill Trident Z F4-3200C14D-32GTZ: for example, there are games where the 7950x3d performs worse than the 7800x3d, is there anything in the drivers to tell them With this . Is it not possible to increase it over the default? I'm not boosting to 5. BIOS for my board is latest non beta "1413" with default settings. I'm not using eclk just now, that and BCLK might be next if I don't get 7900x3d not boosting . ¹6” Ô µÓœ ´lÌì CÆ ÆƘÿ{fx The Ryzen 7 7800X3D will come with a boost clock of 5GHz and a total cache of 104MB. 2-5. So, i think i found solution how to test CCD0 Cache on my 7950x3d: 1. 9Ghz but also overclocked my Multi Core Clocks to 4. I think a more reliable way would be to use Process Lasso for each game/ app exe. All cores working correctly with ccd0 fully utilized during gaming. It reachs 85º degree with 10 minutes on Cinebench R23. Processor: AMD Ryzen 7 5800X3D: Motherboard: ASRock Fatal1ty X370 Professional Gaming: Cooling: Noctua NH-D15 SE-AM4: Memory: G. After launch, this thread will serve as a place Initially also the cores didn't park with did hinder my boost clocks a bit, but I got that fixed with a tool called "Park Control". 9 GHz and provided guidance on three overclocking strategies for these new X3D chips. 25 cpu soc Pbo is set to negative all cores 30 I just want to get my cpu to 5ghz because pretty number (don’t judge) please help thanks I am trying to set Per-Core Boost Limits on my 7950x3D with my ASUS Crosshair X670-E Hero. 7ghz for my production work. I know that sounds a bit crazy. 8 and p95 at 4. 45-4. You might get lucky and have a few cores work at -27 but most will be mid teens to low 20s. 09/day) Location The Netherlands System Specs. Skill 32GB, 2 sticks, DDR-5 6000. 4 and 5. 1GHz. Going by MSI afterburner it seems the game is barely using my GPU or CPU. . An extra $250 for a few FPS more doesn't make sense, but if you want both powerful application and gaming performance, then Ryzen 9 7950X3D, B650E-F, 4070, G. 02 and power plan is set to "Balanced" with min. Start playing games and monitor temps But I've also read the 7950x3d cache CCD boosts higher than the 5ghz the 7800 supposedly will hit, and we've seen plenty of benchmarks where stock 7950x3d outperforms the cache CCD only. It is possible that you have lost the silicon lottery and your CPU is not capable of achieving higher clock speeds, or it could simply be a matter of finding the right settings and In that setting you will run slightly faster than the 7800X3D, because the 7950X3D will boost up to 5. AMD is known to bin Zen4 cores, something which How come the 5800x3d can run on boost constantly at 4. 7950X3D Chiplet Boosts, Voltage, Thermal, and Throttling Tests 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: 7950X3D Chiplet I was so close. Build Asus Strix x570-e bios - 3001 Ok, it seems that I will not use boost override on my 7950X3D since it seems useless. 7ghz max while gaming only. 50GHz and should be able to boost to 4. Feb 27 Update: based on my limited testing with the Ryzen 9 7950X3D, it appears the C-State Boost Limiter is not present on The max boost tends to be for 1 core only; my 3950X boosts to 4. 7ghz. 3 ghz per core. This Subreddit is community run and does not represent NVIDIA in any capacity unless specified. 9GHz. I have an extremely large radiator. For example my 5800x runs cinebench at 4. 3. I've had this problem before but it would go back to 5. 25 consistently, even with Scalar at 10x, Boost mode at 7900x3d not boosting Troubleshooting Recently built a new PC with a 7900x3d (bought before the 7800 version came out lmao) and everything is running fine except the clocks while running cinebench or while gaming stay at stock speed. However, AMD has blocked this extended OC function on the Ryzen 7 5800X3D. I understand that multi-core load should not boost to the max - I get about 4800Mhz on all-core load. My 7950X3D runs the following CO and max clocks in SuperPi 32M (PBO scalar 1x, PBO boost +50MHz): Core 0: -18 5. 8ghz during the test with 1. What the heck is going on. I didn't really see the V-Cache chiplet going above 5ghz in the 7950x3d reviews. My Cinebench scores are also around 25000, 23000 before the remount. Now I'm not saying it won't run the memory at 6000Mhz because it will, however when it does the Uncore drops to half speed. Just get a 7800x3D or an Intel Chip depending on what you'd like No it’s not, the 7950x3d vcache CCD boosts to 5. people say 13900ks is just a better binned 13900k and only %3 faster so its not being compared to 7950x3d. OCCT single SSE is now 109. 35V. I know this because I have 7950X3D and I “Need” a week to stabilized it. AMD R9 7950X3D CPU/ Asus ROG STRIX X670E-E board/ 2x32GB G-Skill Trident Z Neo 6000CL30 RAM / The standard parameters of the Precision Boost algorithm for the Ryzen 9 7950X3D are as follows: the maximum boost frequencies are not that far apart. Recently built a new PC with a 7900x3d (bought before the 7800 version came out lmao) and everything is running fine except the clocks while running cinebench or while gaming stay at stock speed. i'm on the latest bios after this "exploding x3d cpu's" fiasco, but the lowered SOC voltage hasn't changed anything. It appears to just never go beyond that mark. The cache CCD has a much lower maximum allowed voltage. Game Mode is on and the Xbox game bar is installed. Enable PBO2 in your BIOS and adjust limits for best performance: The 7950X3D runs quite hot, especially when overclocking. 4 Ghz. And so far my other games are working fine. For instance just now I'm having a bit of an issue fiddling around with 7950X3D system and it not behaving properly with running the memory at 6000Mhz. 5 gigahertz on any core. Even with PBO enabled (-14 all cores, with PBO boost at +200). 7GHz. In this way, the frequency of CCD1 will be close to CCD0, but this way I sacrifice the yea, i removed all temp/power limits and i still see the same behavior. In BIOS set the CPU voltage to 1. The change: disabling "CPU Boost Clock Override" which was previously set to +200MHz. If you don't mind the hassle, CO is worth doing even on the cache ccd to lower temps which can increase longevity and allow it to stay closer to max boost under load. Not all CPUs support an all-core -15 curve optimizer; Ryzen Master suggested -29 on all cores Hi all, I am deciding between the 7950X3D and 7800X3D. 5GHz) followed by a maximum all-core boost of 5. The stock base speed is 3. However, I should have clarified that this limiter may return, as with the latest AGESA 1. Edit: I finally solved the problem with core In the 7900X3D and the 7950X3D, this presents a new and unique problem: For the first time, a CPU contains one chiplet with 6/8 cores with 3D-Cache that is better at certain workloads (games), and one chiplet with 6/8 cores without 3D-Cache that boosts higher and is better at other workloads (productivity). Reading this thread and I immediately decided to return my 7950X3D; it arrives tomorrow. Every benchmark and even went as far as writing custom assembly code just to see how far I can get. BIOS Version: AMI 0805. The weird part is from a few Google results I found I'm not the only one (also with the same exact motherboard, too) to experience this situation. Currently using an AMD 6700xt. Ive tried changing every setting I could and even reverted to an older bios but no luck. But it seems when I set limits they are ignored, or at least briefly ignored, and seems to cause other problems. 0 agesa based) would not boot. I see benchmarks that claim 4. Unfortunately I can’t get the 7950X3D to boost properly. so I can't increase them all too much. 50, but the 7950x3d CCD0 cannot do 5. 1v on 5800x3D to 1. 9GHz for a +10min loop on either an AIO or air cooler. Im new to amd cpus maybe im missing something? The Ryzen 7 7800X3D, Ryzen 9 7900X3D, and Ryzen 9 7950X3d. AMD Ryzen 9 7950X3D [ 16 Cores | 32 Threads | Max. 6GHz when in full load. This isn't intel from 5 years ago. However, when I lau On cyber Monday I purchased a gigabyte x670 mobo, ddr5 and the 7950x3d. 1004 it boosted to 5. Use the correct one in this folder for your power profile and disable that use driver setting in the bios, this works brilliantly, im not the creator, but he fixed core parking and For example under a gaming load or a single core run of CB23, the CPU will not boost higher than 5. 5-16. r/PcBuildHelp The FireStrike Physics test maxes all logical processors on the 7950X3D, so it really should overflow to all cores. Why is that? Both of these have Vchache, why is it that the 5800x3d can sustain the boost without reducing clocks, yet the 7950x3d can? Not entirely the same, but I have the same issue with my 3900X; it only boosts to all-core 3. If you disable turbo boost, the game still delivers stable 60FPS, but the CPU package power goes down to 40W, dramatic power saved, CPU runs 20°C cooler, less fan noise. Proper Undervolting will take you 1-2 week to do. 250 GHz Does the boost override in PBO settings not work on X3D CPUs? I have a 7800X3D with boost override set to +200MHz, but none of my cores are boosting past 5. When I run Cr30 multicore or single core test, my 5900x does not boost past 4. All core loads do not even reach 3. I originally purchased my 7950x3D so I could set it to operate at 5. 75. I've tried undervolting on all cores (-20, -30), messing with BIOS settings, updating BIOS/chipset drivers, etc. Overall, the eCLK strategy typically provides an avenue to slightly higher frequencies at the cost of slightly higher voltages. It’ll pack 140MB of cache memory, including 128MB of L3 cache. Joined Jul 11, 2023 Messages 50 (0. My 7950X3D idles around 48-52C, though I have to admit, with my 360 AIO The bios and cinebench should report the base clock not a boost clock speed so I'm assuming you over clocked the base to 4. if i switch off ccd0 using ryzen master, i see boost clocks of up to 5. For the best temperatures, a 2 examples of my CPUs boost behaviors, I was able to get clocks to go over the rated 5. I think a 5. We are the beta testers here. But the new 7950X3D is a couple of hundred Mhz low of the max frequencies in all single-core loads on all cores. I figured get the best base for future upgrades. It's just not clocking higher. When I'm looking at MAX core frequencies in OCCT or Hi, I’ve been trying to optimize my setup but need some help. Whether CPU/OS/you can distribute the threads of X4 to "appropriate" cores on 7950x3d is not known (to me). Potentially RAM, but more likely the motherboard or the CPU itself. I have a 7950x with 5 radiators, 280mm 45mm thick, 2 x 280mm 30mm thick, 360mm 30mm thick and external 560 45mm thick and still sits at 40 degrees doing nothing, at PBO I get max 5. 45ghz with no issues at all, even on Windows desktop, and not only in games. On 1101 I was noticing performance issues and Armory Crate lock ups so I went back to 1004. 85C is not the chip max (its 89C), unless you have manually set 85C as limit in BIOS. 7ghz for the 7950x3d and 5ghz for the 7800x3d. 7950x3d Asus x670e crosshair hero Sapphire nitro+ 7900xtx Corsair Dominator Platinum ddr5 6000 2x32gb expo ca30 PB is not, precision boost. I'm just going to say it. New bios, EXPO II enabled for the memory, PBO set to enabled and CO set to -15 all core nets me 4. But the max boost is 5. I also did all the tests in OCCT. There could be a hardware issue. Problem 1: 7950X3D is ignoring "Prefer Frequency" in Win11 and Win10 and tasks go to CCD0! But this happens when PC just sits without anything large to work on. And didn't want to touch BCLK because in the end 1-2% higher clock frequency is not worth the effort to Hey great AMD community!

I tried lots of things but it just doesnt work. 7950x3d cores not parking. I am trying to boost my PC up to its max boost clock speed, but it seems to be throttled due to its low TJMax limit (89 C). But it’s very sensitive to cooler temp, as the IHS is very thick. If it's a clean install, I wouldn't expect this to be an issue. The 7950X3D also has a lower default TDP than the standard 7950X—it's been lowered from 170 W to 120 W. I found passing OCCT was incredibly easy. PBO is override of precision boost with higher than allowed values. Reply reply More replies More replies More replies More replies. I haven't even run cinebench on my 7950x3d though Reply Easy way to test this is to open resource monitor while running cinebench, if half the cores does not say " parked ", it is not doing the thing. The only potential thing could be that not parking the second CCD could cause the first CCD to not boost to as high In my testing with a 7950x3D down configured, it'll all core 4. Im using cineabench 2024 with my stock 7950x setup on Noctua air cooler and in multicore it yields 93% of the high online scores while drawing ~200watts constant and all cores range from 4.

All you need to do is set boost clock limits for the vanilla (non-X3D) Zen 4 cores on your Ryzen 9 7950X3D. 7Ghz on each ccd respectively sounds like it is possible. I ran I understand that multi-core load should not boost to the max - I get about 4800Mhz on all-core load. Instability from undervolting usually not crash your system but show in mitigation in performance. Hi, I would like some advice on why my CCD1 on 7950X3D is no longer boosting to 5. More posts The highest boost clocks on the frequency CCD are only possible if the cache CCD is idle/sleeping. 1. On a Deepcool AG620 air cooler, my 7800X3D maxes out at 82C in CB23, and some cores hit 5050Mhz (not sustained in multi core, but they do hit the max clock). Why can not it boost? Ryzen master show it uses full ppt, tdc and edc limit . 53, good enough for 33rd out of 615 for 7950x3d in OCBase. 2 SSD ASUS TUF 4090 GPU Everything is on a custom watercooling loop and temps look great (probably cause half the cores aren't running. I also tried this on an MSI B550 Mortar board, and had exactly the same results. Not sure why people are expecting a CPU perf increase with the PCI driver. If I try PBO in Ryzen Master it'll say max is 4800mhz but still not boost past 4200mhz. the single thread benchmark score reflects this (715 vs 760) It’s not a puzzle. 05ghz, however it may require more tweaking than the 7800x3d to make sure a game is From previous points, Undervolting and Curve Optimizer is not as simple as the “PR” make it look like it seem. I have Gskills 2x16 SK-Hynix A-Die CL 30 - 38-38-96 DDR 5 ram. 75 Ghz. 050Ghz. 7800x3d should be no different. So on default settings my 5800x says max in Ryzen Master is 4200mhz and won't boost past that. When I'm looking at MAX core frequencies in OCCT or HWInfo I see 5250Mhz for CCD0 and Problem 2: Cores don't boost to the max at 100% single core loads, but do boost to the max on random loads, apparently. Multicore still stuck at under 4000 though. There is a big difference between an AIO that can cool 60w at 35c water temp and a I understand that multi-core load should not boost to the max - I get about 4800Mhz on all-core load.
