920xm Throttling

So I was having throttling problems in games with the 920xm and 460m. I originally thought it was the 460m because the temps were around 70-80C on CPU so I figured that was okay.

Note: These are both stock/not overclocked

I decided to see how it was doing in Prime95.....low and behold once almost all cores hit 85C, I saw the CPU throttle and the temps dropped to around 74C
Is this normal? I thought it could run up to around 90C.

So I'm assuming it's a temp related problem and I would need to re-paste the CPU. Should I even have any power issues with a 920xm and 460m?

I underclocked the 920xm, and haven't throttled since even if I overclock my 460m. I put the multipliers to 22,21,15,15.

I guess my main question is, even after I repaste etc....would I run into problems putting it back to stock speeds because of power supply issue? Or is that out of the question and I shouldn't have any power issues at stock speeds and it's purely temp related as I figured out.

 

Repaste to help with temps and also use throttlestop to stop the throttling. (check the "chipset clock mod" option and make sure its set to 100%)

 

huh, didn't know checking that is supposed to help throttling. Okay thanks, I need to wait for my PK-1 paste to get here

 

That option should stop CPU throttling altogether unless of course your temps are getting close to thermal shutdown. As long as you can keep temps below 80C and using that chipset clock mod option you shouldn't really experience any throttling.

 

Okay thanks, yea seems to not reproduce the throttling when hitting 85C temps in Prime95. But still, the temps are way too high for stock clocks if I'm not mistaken. They only looked to keep increasing also given time. I've backed the multipliers to 24,23,15,15 for now. I just hope the system is drawing too much power to the point where the GPU is starved.

 

A stock CPU and GPU that's is officially supported by the m15x should be fine and neither should be starved.
