Brand new Phenom II 970.. Sanded to awsomeness

post #1 of 7
Thread Starter 
So I decided to see how concave the Stock HS and IHS was on the new 970's..
Unfortunately I did not take pictures throughout the process... Just final products.. Its Lapped to 1500. The IHS had a huge bump in the center I used 2 full sheets of 600 grit to get it flat....... The HS Had the same issue Huge bump in the middle. It also came With the contact point sanded with like 220ish.. It was a horribly rough surface...

Out of box the CPU with default Clock and Volt settings could not run prime... It comes stock clocked 3.5 @ 1.4v... Wich in testing is about .750v too high. The chip runs 5 hours prime stable 3.5 @ 1.325v

So I will have to write a follow up in a week. Im using AS5 tim.. So final temps will not be correct until it fully cures.

Unlapped fresh AS5
Prime95 Exceeded TJMAX 3.5 @ 1.325v
Folding 24/7 - 57-58c

Unlapped Cured AS5
Prime95 1 hour - 57-58c 3.5 @ 1.325v
Prime95 1 hour - 59-60c 3.75 @ 1.365v
24/7 Folding 54-55c 3.5 1.325v
24/7 Folding 59-60 3.75 @ 1.365v

Lapped fresh AS5
Prime95 1 hour 57-58c 3.5 @ 1.325v
Prime95 1 hour 59-61 tjmax 3.75 @ 1.365v
24/7 Folding 52-53 3.5 @ 1.325v
24/7 folding 57-58 3.75 @ 1.365v

Lapped Cured AS5
Pending...

Pictures!

The CPU IHS Was ridiculously concave... The hump in the middle was so bad on the first pass showed copper in center with 600 grit....

Nice! It's too bad of all my years of overclocking and a member of this forum for close to 5 years i'm still to chicken to lap my cpu/heatsinks. I keep thinking i'm going to mess it up somehow lol.
