The Opteron Skt 939 Overclocking thread !!!!

Thats what I want to find out, how much difference running single-channel and 2T makes. And im running 2 sticks, not one.
 
lol PRIME95 goes on until you stop it... it's a torture test for stability, and you should be able to run it error free for at least 12 hours to claim your overclock is stable.
 
I think it's 1.6 or slightly over, i'm going to try and measure it with a digital multimetre in a bit... though im not quite sure how to use it lol :)

There's a big dial in the middle and i'm not sure what to set it to for measuring. :o
 
Aghhh i've seen whereabouts to measrue it but not sure where the black and red goes where. Can someone please do a quick MS paint guide for idiots on checking Vcore on the DFI? :)
 
Hmm well I can't reach the bloody thing because of my SI-120 so i'll just save it for another time.

Ran 4 hours PRIME @ 2.7ghz fine while browsing so im moving up to 2.8ghz (there now) but voltage is a bit high lol, around 1.7v.
 
Nem if they both hit 3 Ghz can I have the worst one, preferably the 146? :D

EDIT - tatts i'm at 2.8ghz now and priming so i'll try and lower the voltage a tad if it proves stable. :)

i need more V to get past 9x300, now @ 9x310 1.6V (1.450 + 110%) :D

Heh I thought you'd need a bit more juice. Hopefully when this proves stable at 9*311 i'll be able to back down to 1.65 or so. Which may then leave me enough room to shoot for 2850 or 2900 with 1.7v. Probably a bit optimistic though... lol. 2.9ghz stable on a cabbage would be quite extraordinary with my cooling methinks. :D
 
I just stopped PRIME as it was making browsing VERY painful. But although im going to let it run for at least 8-12 hours when I get chance, 3 hours with no errors or warnings is looking good for 2.8ghz with ~1.7v. My heatsink is cool to the touch even straight after the 3 hours heavy load... these 120mm fans work sonders... my RAM is cool too.

And I know it's all due to the fan and the heatsink is seated correctly because the other day my fan stopped when a wire came loose and after 1 minute my heatsink was too hot to touch and my RAM heatspreaders were almost as bad. Great heatsink! :D

In the BIOS make sure the LDT multiplier is set to 3x, any higher and it will screw up at high HTT. Also, you may need to run a divider (if you're not already).
