So we've tried DDU and installing this driver, but it did not help. Afterwards, as leclod suggested, we tried to take out the M.2 SSD and mystery was probably solved. Game started to behave normally and GPU power in game was around 230 W on RTX 3070 (since it's in the PC atm because we tried to eliminate one of the possibilities). I still don't know, why it happens, because on a very similar setup (with the only difference being B460-F MB - my friend has B460-H) it doesn't affect performance at all.

Checked for update for the BIOS, found out that the latest BIOS is installed. (version 1620)

An NVMe drive was added a few weeks back (the 970 EVO PLUS), but I’ve added the same SSD to my system, but without performance drops. (I have same CPU, but only the MB is a bit different - B460-F instead of friend’s B460-H)

I did the test following the guide and here is the .csv file logging.CSV

Here are the screenshots from Cyberpunk on 3070, game is set to ultra on FHD.

Hi there, a friend of mine has a problem with his system. He’s experienced a performance drop by 20-30 % in the last few days. His specs are: OS: Windows 10 CPU: Intel i7-10700K GPU: ASUS TUF RTX 3080 MB: ASUS ROG STRIX B460-H (not sure of BIOS firmware, but it hasn’t been updated in the last few days) PSU: Corsair RM850x RAM: HyperX Fury Black 32 GB, 2666 MHz Recently the FPS and performance in general has dropped by the 20-30 %. Drop in 3D Mark from 15 500 to 13 200 points. Cyberpunk (itself installed on a Samsung 970 EVO PLUS) started dropping FPS. The PC case is clean, dust free. We’ve tried installing older GPU drivers (DDUing in safe mode the newer ones), with no effect. Also tried swapping GPUs for mine. (I have almost the same specs except for GPU, I have RTX 3070) That did not help either, since the performance was worse on his system with the RTX 3070 than on my system with the same GPU, CPU and RAM. Also tried reinstalling Windows, no effect as well unfortunately. The temps are not higher than before (the 3080 sitting around 65 degrees Celsius, the Intel with Noctua NH-U12A around 70-80 in high workload. We’ve tried OCCT power test for the PSU, but it seems ok (no crashing, nor low power delivery to CPU/GPU). We’ve run out of ideas, could anyone please help us resolve this issue? Thanks in advance.

Thank you all for your replies!

The little problem is that the CPU temps when at 125 W are OK (a bit below 70 degrees Celsius), but when it boosts it goes to the higher 70s and lower 80s, then it drops (because the turbo stops).

So, I have an Intel Core i7-10700K, when I use Folding@Home, it uses the CPU at 100 %. The clock is at 4,66 GHz (which should be normal), but after a while (about maybe 10 seconds) it drops to 4,33 GHz. I would like to ask, if that is normal (maybe that the first 10 seconds it is in turbo mode)? I have not done any overclocking to the CPU. My cooler is Noctua NH-U12A. I also looked into Intel XTU, when it starts the TDP goes to about 170 W and then it drops to 125 W (which is what the manufacturer says), so it probably is normal? Thanks for replies

I am happy to hear that! Enjoy your new PC! It is a great experience to build your computer for the first time, right? What components did you go for (CPU, GPU, etc.) if I may ask? P.S. Yeah, cables are really the worst!

I would put it the way, so that the fan is facing the hole on the bottom of the case.

A good thing would also be a good thing if some of your friends had some experience with building PCs to do maybe a video call with them, so they can also help you.

If you are careful enough and follow the instructions and reccomendations from build guides (and the included manuals from the PC parts), then it should not be a huge problem. It will probably be your first build, so it will take more time. But be careful! If you don’t feel like building it or not encouraged to do it, then it is totally fine and then you should probably wait a while and leave it to some proffesionals or experienced builders. Anyway, if you are going to do it, good luck and enjoy your new PC!
