Hi,

For the past few months now, my CPU has been randomly throttling itself by reducing the multiplier from x15 to x4, effectively making it run at a quarter of the speed.

I have not completed ruled out overheating as when this throttling occurs, any application that can show CPU temperatures shows it at either 255 degrees (CoreTemp) or -185 degrees (AMD OverDrive Thermal Margin).

I have tried disabling AMD Cool 'n' Quiet as that causes the multiplier to vary, although that did not help. 

I am currently using:

AMD Phenom II X4 960T

nVidia GeForce 760T 4GB

MSI 970a-G45

Corsair 650W PSU

Any help in fixing this throttling issue would be greatly appreciated!

You could try manually setting the multiplier.

There should be no reason for Core Temp to not read the CPU temp properly in the 40C-70C range. Usually strange temp readings are a mobo issue if the software is known to be good. It's possible there is a BIOS issue also. You could try an older or newer BIOS if need be to see if it eliminates the problem.

FWIW- AMD Overdrive's "thermal margin" reads improperly so I would not recommend using it.

Building a reliable PC involves more than just assembling the parts. You need to be able to configure all of the BIOS settings appropriately. This can be quite involved and frustrating as it can require a lot of trial and error with stress testing. It is however often the only means to get a 100% reliable PC.

I am unable to set the multiplier myself. I set it to x15, but nothing actually changes. Someone else told me it could be a motherboard issue too, but could the motherboard also be causing the throttling as well as the incorrect temperature reading?

Also, I found that disabling something in my BIOS called 'Smart CPU Protection' stopped the throttling, buit the overall performance of the computer still felt slow and sluggish.

CPU Smart Protection is typically a safety device to prevent the CPU from overheating - by throttling it.

Yes the mobo/BIOS could cause the incorrect CPU temp readings and throttling.
