Hey guys!!
I applied a little undervolt to my i7 13700k on my Z790 Tomahawk DDR5; I don't know much about this stuff, but I don't think I did anything wrong, exaggerated or fried anything… yet I experience very low fps on 2 games that should run way better.
I'll leave a photo of what I changed in BIOS but basically:
AC Load Line: 80
P1: 253
P2: 253
Current Limit: 307A
Lite Load Control: Advanced
Adaptive + Offset: –
Core Voltage Offset: 0.100
I also manually locked Pcores to 53 and Ecores to 42.
That's all I did.
I FINALLY was able to reach 30k scores on cinebench and TimeSpy both Normal and Extreme are giving the expected results… I lost 10k all over the place in all benchmarks on latest bioses;
But both Returnal and Cyberpunk 2077 are running very poorly and I can't underatand why.
I thought it was something I messed up in bios so I CMOS reset on the mobo itself, I left intel default settings and nothing changed… so I rolled back BIOS to a stable version with the 0x129 microcode (I was on the latest MSI bios with 0x12b microcode) and nothing changed again: I lost 20/30 FPS on Returnal (4K Ultra with Ray Tracing Native circa 80/90 FPS instead of 110/120 I was doing before) and lost circa 40 FPS on Cyberpunk 2077 (4K Ultra with Pathtracing, Ray Reconstruction and DLSS Quality, I should get around 60/75 FPS but I'm locked at 45FPS).
(GPU is a 4090)
I did 15 runs of C15, several runs of Linpack on OCCT, stress tested with TimeSpy Extreme and several runs of C23 and there are 0 errors nor Whea Errors, Vcore max is 1.315, I still thermal throttle (AIO Z73 KRAKEN 360mm) but ONLY under load with stress test utilities (65° on Returnal and 58° on Cyberpunk).
Weird thing is other games run as expected, such as Lords of the Fallen 2023, Deathloop or Dead Space Remake (4K, Ultra, Raytraced and I get 120fps), even Elden Ring.
Last resort is a clean install… but I didn't do anything software wise on Windows.
Does anyone have any insights to share?
Much appreciated, thank you!
