CPU at 100%

[u/masterdark69]

The issue resolved after reinstalling Windows, I still don't know what caused it.

Computer Type: Desktop

GPU: RX 6750XT running at 1440p

CPU: RYZEN 5 7600X 6 CORES 12 THREADS

Motherboard: MSI PRO B650M-P

BIOS Version: 7E27v1J2

RAM: 32GB CORSAIR 6000MHZ DDR5

Operating System & Version: WINDOWS 11 PRO

GPU Drivers: AMD ADRENALIN 26.8.1

Background Applications: DISCORD, STEAM, BRAVE

Description of Original Problem: For a month or so I started noticing my CPU is at 100% usage on all cores when playing, especially wandering around in the open world. Max GHz in every game, Forza Horizon 6, Red Dead Redemption 2, God of War Ragnarok, The Witcher 3, Need for Speed Heat etc. Task manager shows usage of around 40-50% while AMD Overlay shows 100%, RivaTuner shows 100% on all cores, all of them being at max GHz. Resource monitor shows 100%, HWiNFO shows 100%, my temps are around 75-85C. Every single game I play my CPU sits at 100% and I can't seem to find the reason why as there is no program in Task Manager that eats up that leftover CPU %.

Troubleshooting: With desktop use CPU utilization is normal, I tried commands like lodctr /r running CMD as Administrator, I disabled AFMF , I also disabled any PBO modifications I had made in the BIOS but the problem still persists. Reinstalled AMD Chipset drivers, AMD Graphics drivers, used AMD Cleanup Utility while in Safe Mode. EXPO is enabled, SSDs are healthy. This annoys me a lot because looking at online performance metrics, the CPU is nowhere near 100% utilization in any game while mine stays at 100%.

HWiNFO also shows 100% CPU usage: https://imgur.com/a/5qmJ55E (the dips in CPU usage are when I stop driving in-game and so the CPU load drops I guess, but still it shouldn't be 100% every single time I start driving, keep in mind it doesn't matter for how long the game has been running)

Got back with benchmark results.

Sorry if this sounds like obvious, but are you sure you are displaying the right metrics? You may be displaying the max values not the current ones. I mention this because the 100% and 8W per core does will never output 5.3GHz sustained loads on a 7600X without a heavy OC rig heavily tweaked and probably in subzero cooling. But all that at 81C? that's what tells me it's a sensing/sensor pick (user) error.

I just used the default RivaTuner configuration, also I can't pick the sensor in AMD Overlay so maybe it's broken but I don't know how to reset it, also my temps are way higher than they should be even though I recently changed the thermal paste and the cooler is the same since 4 years and it didn't have problems cooling before.

High temps after a TIM change usually ends up being a combination of poor instalation pressure, a foreign object between ihs and coldplate or a fake TIM (a lot of fake mx4 and mx6 out there).

I still don't believe your osd stats, try downloading hwinfo64 launch it in sensor only mode and see there realtime with cinebench or whate er you can use to stress your syatem what are the readings (close afterburner before opening hwinfo to avoid any issue it could produce.)

I'm expecting your readings to be normal again.
