FX 8320e overclock multiplier drops in prime95
FX 8320e overclock multiplier drops in prime95
I recently acquired an FX 8320e for some testing and overclocking purposes. It’s currently running at 4.2ghz with a voltage of 1.375v. During stress tests in prime95, the multiplier would temporarily drop from 21 to 7 (from 4.2ghz to 1.4ghz). I attempted to use AIDA64 for stress testing, but it reported high CPU temperatures reaching 58°C while my cores stayed below 39°C. I’m unsure what to believe with that tool.
I’m back at prime95 again and still facing the same issue with the multiplier. I’m using HWmonitor, Open Hardware Monitor, CoreTemp, and SpeedFan to keep track of temperatures. All monitoring tools indicate core and package temps around 44°C, never exceeding 47°C except in SpeedFan where the CPU peaked at 68°C before dropping to 60°C (core still showing 44°C). The CPU load remains high during stress tests.
In the BIOS, I’ve disabled C1 state, C6 state, and CnQ, with the CPU fan set to full speed on a Hyper 212 EVO. I’m also noticing significant voltage droop in the BIOS—this is something I can’t find elsewhere.
For my part, I’m struggling to understand why the multiplier keeps dropping or if this is even an issue. It’s unclear whether it’s due to thermal throttling or something else. All signs point to temperatures being within normal ranges.
Any assistance would be greatly appreciated! Thanks!
Alright, thanks for the assistance. I believe I've resolved the issue. The CPU was slowing down because of high socket temperatures. My cores are fine and within temperature limits, but the socket temps exceeded 70°C which triggered the throttle. Anyway, thanks!
So apparently I lied. My socket temps were around 65°C and cores at 52°C with a voltage of 1.375V. Still throttling down the multiplier from 22.5 to 7. Not failing any tests but still annoying.
Btw I managed to get the vdroop issue under control—adjusted the Vcore offset so it runs at 1.4V when not idle, but drops to 1.36V under load according to CPU-z. Any ideas? This is really confusing!
