I have a Ryzen 3600 running at 4.5Ghz all core, stable on OCCT at 1.35v. 99% of the time it stays under 65c, the problem is that under a multithreaded AVX workload temperature spikes quickly with a 124 watt load compared to about 85 watts normally. I’ve tried just about every setting in PBO but nothing works. I’ve had no issues with wattage limits or AVX offsets on Intel, is switching back really my only option? I’ve tried this on two different motherboards now as well, an Asrock Phantom 4 X570 and a Asus Prime X570.

Hi people

Have been doing some overclocking on my CPU (i9 13900kf) and 4090FE. Since upping the GPU OC the benchmarks have revealed that the 990 Pro is underperforming, at least at half speed. I've removed the GPU OC and reran tests but the performance hit is still there. I've checked, it's in a PCIE Gen4 slot, and it's health in Samsung Magician is OK. Firmware is up to date on the M2 and bios etc. Any ideas what I am doing wrong? Prior to this the M2 was fine. Temperatures seem fine, not going above 55C on the M2

I have a Ryzen 9 5950x on a ROG Strix B550-F Gaming (Wi-Fi) motherboard. So I decided to enable PBO and was using PBO2 Tuner to find the best values for my PC.

Basically what I did was set the PBO values to Auto in the BIOS, and then use PBO2 Tuner to modify the values. Then I run Cinebench R23 and note down the score for each combination.

After hours of tuning and testing, I decided that the following combination gave the best performance: PPT 205, TDC 135 & EDC 145. With those values I could get about 27500 multi-core score in Cinebench R23.

To make this setting applied at start-up, I put those values into BIOS. Saved and restarted the PC. Opening PBO2 Tuner and Ryzen Master showed that the values were correctly applied. The problem is when I ran Cinebench R23, I got a significantly lower score of about 26100 multi-core. I tried restarting the PC a few times and rerunning Cinebench, but the results were consistent.

So I am rather perplexed by this. Why is the CPU underperforming when PBO is set in BIOS versus being set via PBO2 Tuner? To analyse the matter further, I captured screenshots of HWiNFO64 while Cinebench was running the multi-core test. I did it for both cases, with PBO values set using PBO2 Tuner, and the values set in BIOS. The screenshots are as follows:

HWiNFO64 screenshots

I highlighted the relevant values. You can see that in the first case (left screenshot), we got a max TDC of 135 A, max EDC of 145 A and max PPT of 189 W. The CPU Core Current reached a max of 135 A. On the second case (right screenshot), we only got a max TDC of 123 A and max PPT of 168 W. Only EDC reached the set limit of 145 A. CPU Core Current reached max of 123 A.

I don't understand what is going on here. Why is the CPU performance seem to be depressed when PBO values are set in the BIOS? Can someone please help explain?

Hi guys, just wanted to know if there's a way to underclock vram further with MSI afterburner. -1000 or something like that. My 3060 is kinda broken and lowering the vram clock seems to fix it.

Thanks!

I thought this sub might like a laugh.

Been water chilling for years, real simple setup:

100l reservoir, 2x 240mm rads in reservoir. 2xdda at full speed as the loop is nearly 20m long

Loop temp 6c

CPU temp max 96c LOL

I usually push 5ghz but I'm slowly bringing the voltage down.

Clock Stretching*

This is with Kombo strike 3. The same thing happens with Kombo Strike 2.

Sometimes the core effective clocks don't match the core clocks when running prime95. I haven't had any crashes with KS3 enabled while gaming and video encoding.

Without Kombo Strike my core clocks don't reach 4.450 MHz at all under multi-core load.

Cinebench scores are higher with KS3 than stock.

I have a taichi 7900xtx and was led to believe its one of the better if not best air cooled cards you can get and would see decent performance improvements over the reference. However when running passmark with my own overclock settings, i get 1800 points below average score of the same card. Have I just lost the silicon lottery and do nothing or any tips to squeeze more performance out of it?

My own OC settings are: 1030mvs 3ghz clock max 2.4ghz clock min 2.7ghz Vram clock

When checking temps they stay below 90c so it might not be thermal throttling, but any suggestions?

Just posting my memory overclocking experiment with the new BIOS

Platform: Ryzen 7700X, MSI B650 Edge

Memory: F5-6400J3239G16G (6400MT/s 2x16GB 32-29-29-102 CR1T Hynix A-die)

XMP only OC in AGESA 1.0.0.7A stable BIOS:

• XMP only, no change
• BeforeOC.png

6200MT/S After OC in AGESA 1.0.0.7A stable BIOS:

• Downclocking to 6200MT/S to pass Memtest64 here is a must
• Same OC settings as Buildzoid's stable Hynix timings
• AfterOC.png

6200MT/S After OC in AGESA 1.0.0.7C beta BIOS:

• I'm using the iGPU on 7700X here which cumbers some performance
• Same OC settings as Buildzoid's stable Hynix timings
• Read, Write, Copy & Latency has improved
• AfterOC-BIOS173-6200.png
• AfterOC-BIOS173-6200-2.png

6400MT/S After OC in AGESA 1.0.0.7C beta BIOS:

• I'm using the iGPU on 7700X here which cumbers some performance
• Same OC settings as Buildzoid's stable Hynix timings
• Another visible bandwidth improvement, without a change in latency
• It passed MemtestPro, all 16 threads in 29760MB for 1.5 hours test with ease (manually stopped at 121% coverage)
• It passed y-Cruncher for with each algorithm taking 120 seconds, manually stopped after half an hour
• However, I only got it to boot once & never again, it appears to be stuck on POST. I have tried these following (which involves resetting BIOS for ~30 times) but non of them worked
  • Raising DRAM voltage (VDDQ, VDDIO, DRAM-VDD) from 1.35V to 1.38V
  • Raising SoC voltage from 1.25V to 1.28V
  • Reducing PBO2 negative offset from 26 to 25 (CPU LLC mode 3)
  • Turning on SoC LLC mode 3
  • Combining all the changes above together aswell
• I ended up fixed it by dialing back DRAM speed to 6200MT/S and everything went back to normal, so I conclude this as a beta-BIOS thing, it needs a stable BIOS upgrade later

When I run cinebench r23 my 13600k never gets above 85c, but when I've been playing baldur's gate 3 recently it occasionally spikes up to 95c ish. It never stays there long (like a few seconds maybe) and then goes back down to 65-70c. Is this something to worry about? My cooler is a noctua nh u14s and I used a thermal grizzly carbonaut pad which may also have something to do with it. Thanks.

Hello everyone. I would like to go direct die with my 10900k since it's now quite "old" and it is no longer under warranty. I've got a pretty good sample which can go 5.3GHz allcore at 1.335V, problem is that i'm extremely restricted thermally, so I tought about going direct die. Rockitcool direct die frame is out of stock everywhere and since it's an old cpu I don't think it's ever going to be restocked, what should I do here? Does anyone know any alternative?

So I recently built a new PC, and everything that i've read has said that my i9-13900K should trying to turbo itself so much that it thermal throttles and should hit 100 degrees Celsius, my experience however has been the opposite of that. Running Cinebench R23 I never get above 68 degrees Celsius for CPU package with a ~35500 score, and power draw is limited to ~235 watts with the P core ratios stuck at 50x. The BIOS defaults to a target P core ratio of 58x for two cores and 55x for the other 6. Does anyone know why my chip is presumably power limiting itself and what BIOS settings might be wrong? The BIOS settings are mostly at defaults, the only things that should be changed is the DRAM Frequency was set to 4800Mhz (from 4400Mhz), and in hopes for increasing my power draw, I set CPU Core Unlimited Current Limit and GT Unlimited Current Limit to Enabled. As this is a workstation/server motherboard I'm sure its settings dont default to what you would see in a typical gaming board. Please note that the W680 chipset this motherboard has is the same thing as a Z690 but also enables ECC memory as it seems that Intel's plans are phase out the Xeon E series.

BIOS Settings:

CPU: Intel i9-13900K

CPU Cooling: EKWB Nucleus 360mm AIO - fans replaced with 120mm Noctua Industrial PPC 3000RPM fans at 100% speed. Thermal Grizzly contact frame installed with a calibrated torque driver to 0.045nm. Thermal Grizzly Kryonaut Extreme thermal paste.

I have no idea how to overclock, and just set my CPU to 3.9 ghz overclock with a core voltage of 1.35. Launched cinebench and ended up crashing because my CPU went over 100C with the stock cooler...

Do I have to change my voltages or should I lower the CPU clock to a more comfortable 3.8 or something even lower?

If anyone had thoughts about getting a 12/13th gen contact frame, it was the best $13 ive ever spent.

15c Drop on the hottest core? almost 1c per $1 spent. I swapped out my stock bracket and corsair TIM for a contact frame and TG- Kryonaut

Dont roast me too hard on the pic quality, Top pic is stock after 3 runs of R23, Bottom is Contact frame and TG TIM after 3 runs of R23, 12700k 5.1ghz Pcore 4.1ghz Ecore, Custom loop

My system recently ( past 6 months) began having crashes almost instantly after pressing the power button, immediately after the screen begins to light up but before the bios screen. My ram and cpu have overclocks or PBO, and I was wondering what the ways were to narrow it down. I had the system for over a year without this happening.

So hwinfo is giving me some (bugged?) readings for my ram.

The voltages are super high and not updating at all.

Is this just a bug or something to worry about? What about those PMIC warnings? Are those worrysome?

Hi! I saw i can buy 4070 strix insted of tuf, anyone have it? Anyone can tell me which one is louder? Temps? And is 12vhpwr to 2x or 3x 8 pin take more power than direct 12vhpwr to 12vhpwr?

So I've been trying to be careful here cuz I definitely don't want to do anything problematic to a GIGABYTE product after all, but I've been struggling for days to optimize my system for games and I am getting bitches here or there with the tdp dropping low 100s correlating with stutters and 10-20 fps drops in my games (however I'm fully aware it very well could be the games themselves) the main source is that it does happen in more demanding games cyberpunk, BG3, RDR etc etc I play at 1440p and yeah have absolutely used the DDU utility (fixed a lot that one) removed propriety software and bloat and minimize my sensor usage, all the basic stuff to lessen memory load and whatever could cause it.

Best I can tell my 4080 is just NOT using it's power effectively rarely goes above 220tdp and I feel like I'm losing my mind cuz when I use timespy it fully draws the card to 320 watts and runs brilliantly, hence why i think it might be software (aka the games) but there's nothing I can easily find detailing a solution to my worries.

I run a Gigabyte b650 aorus elite with a Ryzen 9 7900x 2x16gb gskillz neo ddr5 6000mhz (expo on, tested and no correlation) and a gigabyte aero 4080oc at 1440p

I'd love to just feel like I'm being a stickler and just need to accept some games will just be annoying but figured if there is anywhere to ask it's here yeah?
