cpu multi drops when cpu reaches 51c

post #1 of 11
Thread Starter 
so every time my cpu reaches 51c my multi drops to 4x. can any one explain why this is happening? is there a bios setting im forgetting to change?

It sounds like thermal throttling, it's a while since I've looked at an AMD BIOS but I think the feature is called Cool n' Quiet, try disabling that and see if the problem stops.

Are you seriously reaching 51c with a D14? Did you do a good seat? What is your voltage? At 1.475, I never went over 53C so a D14 should be doing much better.

Something is getting too hot. Voltage Regulators(MOSFETs) maybe?
Mobo model? Can not find M4A8TD. Wanna see how your MOSFETs look

Thats your problem. Cool them and everything should be OK.

EDIT: You need a heatsink for them

I have the same problem with an Asus M4A78 board and an old phenom 9500. I've update the bios, and that didn't resolve the problem, cool and quiet is disable. I have tried everything and nothing had work. I think is time for me to do an upgrade.

If you're trying to overclock a Thuban without MOSFET cooling you're going to have problems.

Find some heatsinks and tack them on.

The 87TD EVO, despite 8+2 phase, is actually known to get pretty hot. In any such case OCP may protect you. Since you're running the most TDP-heavy AMD processor on an overclock perhaps at high volts, and with the tower cooler you may not be getting any air down there, then a MOSFET heatsink may be indeed the solution.
