Background:
AMD FX6300 @ 4.12Ghz and 1.425 volts
ASrock 880 GM LE FX Mobo
Coolermaster Seldon 120v water cooling unit
EVGA 500B 500 Watt PSU
I don't think anything else there is relevant.
I built this system back in the fall of 2013. It has worked great, but even at stock speeds the stock cooler was nearly useless. Before today, the CPU under heavy load would work it's way up to 70C and then start throttling itself. The freq would drop to 2ghz range until it cooled, and then back to 4.12Ghz. Basically whatever it needed to keep the CPU right around 70C.
So I installed the water cooling unit. It seems to be functioning great. So I start up prime95 and run a stress test and the temp tops out at about 54C. After about 2 minutes, with the temperature still at 54C the cpu will drop to 1.4GHZ and the VID to 0.9 something. The temperature drops rapidly of course, and then it will pop back to 4.12. It repeats this cycle approximately every 30 seconds. 30 at 1.4, 30 at 4.2, over and over and over. The temp doesn't matter.
I tried disabling CnQ.
I went back to stock speed and voltage.
I even disabled cpu thermal throttling in in my bios.
Nothing helps.
I have no idea what is going on but this is not what is supposed to be happening. Any ideas? Don't be afraid to get technical as I have an associates degree in computer science.
