Is Windows freshly installed on this system?
Cpu temps with that cooler? Monitor with Hwinfo64 or Cpuz and check frequency along with temps. Also check all memory is accounted for and no significant portion in system reserve.
Which games are stuttering and try explain the kind of stutter like is it mini or lengthy pauses.
Have you tried disable efficiency cores in bios?
List the things you've tried to troubleshoot.
I've reinstalled Windows from scratch multiple times. Windows 10 and retrying everything on Windows 11.
CPU Temps are 60-65c (underload) once Hyperthreading is disabled. CPU is 22 to 30C while idle. Hyperthreading on causes temps to hit 75-95C Frequency stays 5.5 ghz at all times. Disabled E Cores and the system ran worse.
Memory is all accounted for only a very very small amount is portioned. Ran tests to check for memory issues and everything came back fine, no errors. System read 64 GBs running at intended speeds. 5600, OC to 6000 didn't help.
Every game is having stuttering issues / mini freezes. I throw a bomb in Vermintide 2 the whole system locks up for a good 3 seconds. A tank blows up in Battlefiled 2042 and my computer freezes. I shoot a gun for the first time and the game freezes for a second I just play little games like Don't Starve Together and I get stutters like on every other game, it's not once in a blue moon either its like 6 times every couple minutes it's so frequent.
I tried disabling Game Mode and Xbox Game Bar, Disabled Full Screen Optimizations. Changed my Power Settings to each one and didn't fix anything. I used DDU in Safe mode everytime I tried something new. I've used AMD Adrenalin on fresh install and manually did everything on other installations.
I made sure everything was up to date, removed all bloatware, undervolted my CPU and GPU, Overclocked everything, tried a mix of both. Followed guides online, tried 6 different drivers. Updated BIOS, cranked all fans to maximum, 20C system still stuttering.
Changed out my power strip, plugged directly into the wall. Upgraded my system 3 times now from i5-10600k to 11700k to 5800x3d to i9-13900k, switching out motherboards, RAM, M2s. 1080 ti, to rtx 3070 to 6950xt.
The games I play are Battlefield 2042, Total War Warhammer 3, Darktide, Vermintide 2, Warzone, Apex Legends, Dota 2. All stutter / freeze. The only game that runs well is Zombie Army 4 from the Sniper Elite franchise.
