The Official Opteron 939 Overclocking Thread

[4Qman]

Anyone else experienced a drop in needed volts to make your chip stable over time?
When i first got my opteron 146 it needed 1.6v to be stable @ 3g or 3.1g, now a couple of months on its stable with only 1.52v @ 3g its saved me about 3c in load temps aswell on my watercooling.

What htt is everyone running? my old winchester never liked anything over 1000 so i always ran 3 x htt, but this opty runs fine at 4 x 300

I also have had the same drop in voltage required. need 1.62v to Prime at 3Ghz stable. I run it at that for around 3mths, once i removed the IHS its now SOLID in primt at 1.52v

Also lads are the CABYE 0540 FPAW Cold BUGGED?

Nothing special but here it is - Opty 148 with IHS removed & on water;



How about a rendertest at 3.2GHz?

28C @ burn???

28C @ burn???

Actually no!

DFI Expert mobo reports too low CPU temp, I'd say add 8-10 'C to those 28'C.
That's closer to the truth.

Btw, removing the IHS reduced load temp by 4-5 'C.
And it's water ...

( It's a cacje but the exact stepping I've forgot )
