CPU Speed stuck at 3.6Ghz
CPU Speed stuck at 3.6Ghz
Hello,
I experienced some unusual buzzing from my PSU and possibly from the CPU or a nearby motherboard component. I resolved it by disabling Core C6 State in the BIOS. Since then, the buzzing stopped, but the CPU speed remains at 3.6Ghz, which is slightly above its normal 3.3Ghz. Turbo core reaches 4.2Ghz. Attempting to overclock to 4.0Ghz without using Turbo in BIOS caused a Windows crash with a blue screen. I also encounter random black screens, though the system still boots even when Core C6 State is enabled or disabled.
Details:
- AMD FX8300 + Gelid Tranquillo rev.3
- R9 380 4Gb
- Asus M5A97 R2.0
- Kingston 8GB KIT DDR3 1866MHz CL10 HyperX Fury Black Series
- EVGA 600B
- 1TB WD Blue HDD
- Windows 10 Education
Is this a CPU issue or something else?
It seems your VRM is probably restricting power delivery to the CPU. Are you adjusting the FSB frequency or multiplier settings?
have you used DIGI power control options for your voltage regulator? they may influence system behavior if configured improperly.
CountMike's analysis suggests the VRM on the MB might be restricting power to the CPU. It seems overclocking on FSB or multiplier could be the issue. The problem was linked to Core C6 State; disabling it restores normal speed but causes a buzzing noise from the PSU. Apologies for the delayed response.
