The Official Opteron 939 Overclocking Thread

i think my 1M time was slightly faster too with this setting

That's a pretty good time there d22. Is that on wc?

I put a 146 in an old neo2 rig they use in the house. When your used to a dfi with all the memory tweaks and then you only have the basic 4, it really makes a big difference in how much of a stable oc you can get. I didn't want to mess around with the TT BT or the hyper6 so I put a smartcat fan on an old silent boost cooler. If I remember right, the MSI core center did not read temps right. It shows 52c idle but I can feel all around it and it doesn't feel hot at all. Anyway, here's a ss with zero memory tweaks (that's why the time stinks). I could run windows at 3000 1:1 but pi wouldn't finish.

Just realised I had ram on 2t.

thanks....yeah i'm on water................BUT I have some problems with 32M times.........not as bad as AFI but certainly pissing me off.............has anyone else compared their 32M times against their old SD or Venice figures here

1M times are unbelievably fast BUT 8M and 32M times are house..........

Abit AN8 Ultra with Venice at 2.9Ghz RAM on 263MHz 2.5-3-3-6 (GSkill TCCD)
32M SuperPI 25m 50sec



DFI SLI-D with Opteron at 2.9Ghz RAM on 290MHz 2.5-4-3-7 (GSkill TCCD)
32M SuperPI 26m 00sec

Here is the first Opteron 175 with some OCing action from a fellow OCAU member

some more results

2600mhz @ 1.39v 32m Super Pi stable


just for a laugh decided to see how low could get vcore

1.2v @ stock speed 32m Super Pi stable, 0.11v below stock


boots at 1.15v but is not stable.

2700mhz @ 1.46v 32m Super Pi stable

load temps around 46c
2750mhz @ 1.54v 32m Super Pi stable

load temps are around 50C

finally cracked the 30min barrier for both cores lol

yeah one core is happy with 1.46 @ 2750 mhz, the other needs the extra volts to be stable.
