Well I'm at 2.7ghz now because my 450w psu will no longer boot up, I have another 450w on it now (12v 20amps) but it doesn't have a PCIE connector. Hopefully my new PSU will get here today, at the latest it should be here tomorrow.

Didn't realize that it would boot up and come up with a msg saying it wasn't getting enough power- and that it underclocked automatically to be safe. It's at 350mhz core (-75mhz), memory hasn't changed.

Gratz on that nice opteron man, those babies are BEASTS! You will hit the big 3.0 in no time! Thank goodness you have the nice ram to back it up!

We'll see, right now I'm undervolting (1.325v) it and still running at 2.7ghz, temps are a bit high for what I'm seeing but I don't have my case fans going. New PSU should be here by tomorrow and I'll get everything hooked up and blowing full blast then.

temps run a tad higher on opty's. and technically they should be able to run at 1.3v stock speeds. i didn't see how far it could go up on 1.3v, but it should hit around 2.5 i'd say.

I just ran dual prime for a half hour at 1.275v @ 2.7ghz. Temps are still quite high, 46-48c was highest it hit, then again I did just re-seat the heatsink.

46-48c isn't that bad. my temps @ 2.8 Ghz was 44c and they pushed all the way up to 46c when i hit 3 ghz... w/o IHS

It's tempting to remove the IHS.. I'm just afraid that I'll kill a core putting the heatsink I have on. Are the cores pretty strong?, this thing has a bit of tension when I screw it down.

if its a bolt on heatsink just screw it down hand tight. if you're really scared of crushing your core get black electrical tape and make it 4 ply and stick it to each corner. it'll help support the heatsink. and cutting the IHS off isn't anything. you just get a paint scraping razor from your local home depot. it comes w/ a little handle thats the perfect size for measuring to make sure you don't hit the resistors under the IHS.

the cores are pretty strong. back before the IHS came on a lot of processors all the cores were just exposed die. you put a little drop of AS5 on it and put the heatsink right on.

Well temps are good right now, set to 1.275v in the bios and I'm running good at 2.7ghz- prime for a half hour (I'll do longer later or just try for 2.8- 3).

The highest temp reached in prime was 45 on the one core, 43 on the other. I'm thinking I'll be ok to bump up the voltage to 1.3 and see if I can go a little higher, 2.8 or 2.75.

Temps dropped a lot, installed the PSU that just came and hooked up all my fans again.

Wow you guys make me feel like crap! Currently I'm running 2.61GHz..highest temp in prime is 45C and can't go any higher on the oc with making it unstable. but good job,
