Reply reply Top 1% Rank by With my 5700g, if I disable global c states, my cores are stable in the -20s (many on -30) in corecycler prime95 AVX2 (important: suspendperiodically=1) With c states enabled, I must reduce the CO to as high as -13 on some cores, because the above corecycler settings cause instafails and hard crashes. Keep SOC, CLDO VDDP, CCD, IOD voltages as low as you can for stability to preserve power envelope. Operating System: Windows 10 Pro 64-bit (10. 1V. If you disabled ALL C-states your CPU is running flat out all the time. I had to disable Global C state control in my bios to stop idle crashes. I actually did.

My fps is better with C -Global C-state control - Disabled-SMT Mode - Disabled-CPPC - Disabled-CPPC Preferred Cores - Disabled It states even there for a low latency workload, you should disable C-States for higher performance. From what I understand from reading around, the actual issue is that the CPU is not getting sufficient power when idle/under low load. C-states are low power states of idle cores while the system is running. It only booted when I disabled the "Global C-state Control" option in the BIOS. 4 on every core except 2 which won't go beyond 4. Disable C-State Ryzen 7950X Try going to Advanced > AMD CBS > CPU Common Options to see if "Global C-State Control" is there.

For those who don't know, Power supply idle control is for older (or cheaper) Disabling C-states just means the processor won't turn off unused parts of the processor while it's operating to conserve power. The freezes consistently stopped when I disabled the global C-state control in the BIOS. Every couple seconds the CPU feels it has time to “relieve” some weight while trying to keep the same clock, this can cause slight latency dips when transitioning in games, running benchmarks, and can help with 3D rendering stutter which offer lower performance. UPDATE 4/27 - So Reason I need to find it is I'm getting random partial windows freezes where things just stop working but my mouse still moves around. Some boards also place C-State options under Precision Boost or Global C-state control should be under Overclocking / CPU features. AMD CBS > CPU > Global C-State Control Enabled In terms of the 5800x3d, and you can test this yourself, it boosts better and gives u more performance. Disabling Cool n' Quiet on the other hand just wastes electrical energy by preventing downclocking of inactive cores and can thereby negatively affect the boost clocks you After I disable the "Global C-State Control" in BIOS, the system whill randomly suddenly reboot in idle. 8. ‎11-14-2024 03:44 AM. After some reading I found that this was an unfortunate common issue fixed by this.

I can still open task manager but it doesn't really do anything. To disable the C states, open the C States With HWInfo64 you can log the cores usage and C-State Residency to see if they are in C0 or keep transitioning from C7 when playing a game.
