1090t Multiplier Drops to x8, PWM Problem?

post #1 of 7
Thread Starter 
Build:
AMD Phenom X6 1090T
G.SKILL 2X 4GB DDR1600 (1.5V - 9-9-9-24-2N)
ASUS M4A88TD-V EVO 880G Chipset
COOLER MASTER Silent Pro 600W
Cooler Master HAF 922
1TB HDD
100GB HDD (I use for overclocking purposes)
Asus ATI 6870
Noctua NH-D14

While im under full load on my 1090t, i get to a point where my multiplier will drop from 15.5 to 8. CnQ and Turbo is disabled and everything. My current overclock is 240 x 16.5- 3960. With the noctua NH-D14 this is what happens while under full load of prime95.

I start prime 95, after 30 secs, it will be at 240x16.5 for 30 seconds. It will hit 42 degrees (Thats my high), and then it will drop to 240 x 8.0 for 25 seconds and go back to 240x16.5.

I do not believe this is a temperature thing because with my stock cooler, i had the same issue, but the temps were higher and it was a lower overclock.
Heres a picture from with my stock cooler

Ive read alot about how other people are having the same problem, alot to have asus mobos, but they all do not specificy how they fixed this.

Not the cpu temp casuing my throttling, but pwm, I had stated in the thread earlier that they were getting really warm and had sinked them, as I had the board on the bench I had also a fan blowing directly onto the area. Now in the case I just had them passive cooled, just stuck 2x60mm fans on them and now no throttling as you can see.
So by 'them' is he talking about the northbridge? Is this an asus thing? Is this the only way to fix this? It will make my build look terrible if i have a fan on my northbridge.

Your high is 54C CORE.

If your CORE is hitting 54C, then your CPU is probably over 64C which means you're probably hitting the thermal limit on the chip and it's throttling itself down.

Obtain a better cooling solution.
