Hey! Yeah, title + a quick recap: I upgraded my entire PC, going from 12600k + 2060 super + 16gb 3200mhz to 14900k + 4070 ti super + 64gb 3200mhz.
The only things left from the old pc are two m2 drives, an HDD drive and a SATA SSD. My motherboard is the z690 a pro ddr4 wifi.
I installed this in two different batches, since I bought GPU, PSU and RAM separately and then CPU + AIO (ROG RYUO III) afterwards. In the meantime, I was using my 12600k with the 4070 ti super and I thought it was getting CPU bottlenecked since I started to see some stutters back then. It turns out that changing the CPU made this issue even worse somehow.
Basically I'm getting very short and weird frametime spikes or very bad 0.1% lows in essentially every game I play. The most affected games seem to be CS:GO, Little Nightmares 2 and Cyberpunk. In those games, I can easily recreate the issue by using CapFrameX just for 120s and then watch the frametime graphs over there. It's even happening in League of Legends which is extremely bad for me since my job is related to the game. The frametime spikes range from 10ms spikes all the way to 50ms spikes. They usually happen once a minute or so. There are some games which are better than others. League for example is quite good but still not perfect.
Even though this issue is very noticeable for me, I do wonder sometimes if I'm being too picky. I'll can leave an image with the frametime spikes if you guys want to judge for yourselves, but yeah, it's very frustrating to spend this kind of money on a PC just to have this sort of experience with it.
That being said, I have tried absolutely everything I could find online:
-Updated BIOS: First thing I did when I received the CPU. I did it with MSI center though, but I've confirmed that it is the last version so it should be fine. Intel Stock settings. I haven't tried going past the limits with that because it may void warranty from what I know.
-MPO, HAGS, MSI mode, Game Mode, Game Bar, etc: I tried basically every single software related option that I encountered through reddit posts and other online forums.
-RGB programs and static effects: I deinstalled SignalRGB which was causing constant stuttering. I installed Asus's Armoury Crate to disable the GPU rgb lighting effect, I tried deinstalling it too
-Hardware tuning: I undervolted my 14900k with LLC3, lite load 3 and 0.07 core offset. (Bullzoid video tutorial, I don't have experience on these kind of things
-Hardware swapping: I used my old PC to try out each component individually, it didn't seem to fix the issue at all. I swapped out GPU, RAM and CPU. The only thing I didn't change was my PSU
-Hardware testing: I used Intel XTU to stress test the 14900k.
-Monitoring software: I tried capping with RTSS, with NVCP. I also tested completely erasing every monitoring software I had.
-G-sync, V-sync: My vx2458-mhd monitor only supports Freesync, so I don't even have the option to enable G-sync from NVCP. V-sync doesn't seem to make any change at all
-In-game graphic settings: no effect at all. The AVG Fps vary, but the 0.1% lows / spikes are basically the same
-XMP: I tried on, off and adjusting memory timings although I don't have experience on this.
-Windows 10/11: I tried with 4 different installs. I tried installing win 10 and then upgrading it to the max. When I noticed stutters, I upgraded to win 11. After that, I reinstalled to a clean Win 11 install. Then I also tried replacing my m2 ssd for a sata ssd, and installing windows there, with no other disk connected.
-Temperature, clocks, power and usage: I checked the graphs from MSI afterburner and I found nothing weird about them, although I do not have a lot of experience troubleshooting like this. The only weird thing I saw was that the clocks tend to go up and down a lot. I tried using high performance modes + disabling C-states + disabling speedshift.
-Interrupt related: I disconnected every JUSB from my case, also the matrix RGB usb from ROG RYUO III.
I also ran this command which I found in a forum (not sure what it does but it did not help):
reg add "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\kernel" /v "InterruptSteeringDisabled" /t REG_DWORD /d "1" /f
-SMT, ECORES: I tried disabling hyperthreading, E-cores.
My guesses so far:
-Something related to my motherboard and I didn't notice it until I changed my GPU for some reason (maybe I wasn't looking at 1% lows)
-Maybe this CPU needs faster ram? I'm thinking of buying some fast ddr4 or a new motherboard with ddr5, although I would love to keep that money for IRL things ;(
-PSU related issue? My voltages seem fine on Hwinfo though.
-CPU issue. I have the possibility to RMA it but I'm not sure if it will get accepted because of the nature of the issue.
Either way, I'm fucking desperate to solve this and finally get to enjoy my PC.
PLEASE HELPPPPPPP
