Thanks. Then it's not throttling due to temps. Period.

The ASUS software reads "CPU Temp" also, which is from the sensor in the socket and again is not accurate under load. Forget it.

OK I wont bother finding the CD, any thing else that you think could cause this?

Throttling isn't always caused by CPU overheating. The motherboard will throttle the CPU for a host of reasons including inadequate power from PSU, too much voltage to CPU (over-current), inadequate cooling to motherboard, motherboards not designed for x6 processors or specifically the exact wattage of the CPU or CPU during overclocking.

OK thanks, I think that I can rule out the MB because I know its made for 6 cores, I will work on some other things and see if the cooling to the MB isn't enough.

Will post results.

Well I have looked into a few more things and haven't found anything different. The MB temps never change more than 1 or 2 degrees from idle to full load. And the CPU temp never goes over 57 deg ( I know ALUCARDVPR said it was inaccurate but I couldn't help myself.)

I did notice that if I let Prime run longer the CPU speed jumps back up to 4 GHz after about 30 secs at the slower speed. Then it takes a couple min and goes back down. It will do this as long as the test is running. My PSU is 950w so surely its not maxing that out.

I think I'm stumped unless their are other things to check.

Looks like this a well known issue on your specific motherboard. What BIOS version are you running on? BIOS to 1702 is supposed to resolve this issue.

Anyone have any suggestions how to fix this?

Thanks
Reseat your CPU and cooler.

I will check to see what version and if I need to update my bios when I get home this evening.


If that doesn't work I'm reseating my cooler with aftermarket thermal paste that I have instead of what came on it.

Your CPU downclocks because of your VRMs(MOSFETs).
Its an ASUS built in protection.

Use a small fan to cool the VRMs. It may help

You sir are correct, I also found the same thing when I did more research. I updated my BIOS and it solved all my problems.

Stable at 4.01 GHz!
