does 37 seem kind of high? get's close to 50-55 1150 1.192 | 1800 1.624

well it is alot better then air...

Have you got the hardware64 monitor that can measure VRM temps on 7970?

check if those are good.

I wouldn't do it. Just clean the stock paste, repaste and done. Because it's not a solid copper and never will sit flush with the core surface. It's a vapor chamber. You might actually dent it and make it worse for contact surface.

50c is ok... doable.

Hey, why is your memory so high? Your card can do 1800 on only .024mv more voltage?

Oh okay.
I thought you were just taking it apart to replace the stock thermal paste (not a good idea).
But since you are replacing it with water blocks, awesome. thumb.gif

For the record, I can run OCCT with a 94c core temp (I did it on purpose) and not get errors at 1070 MHz.

Your 1070 MHz plateau is strictly in OCCT, then?

Might be able to get one of the stock coolers, might experiment with polishing it and keeping my original as a backup. thumb.gif

actually the 50-55 was a dogdy 1200 clock ... seeing 45-50 on loads now with lower volts

I just set it there .... I was at 1637 but was able to back it down ... so far so good

do any of you guys, preferably those w/ single monitor setups notice an occasional flickering? i'm using a displayport monitor and i believe it's one of two things... 1) mini DP -> DP adapter OR 2) Crossfire related

Probably crossfire related. I have no issues with flickering at all with either of my monitors, single or dual. And I'm using DVI and a mini DP adapter (to DVI).
