Initial overclock at 4.6ghz @ 1.47v linx stable... No idea why the gflops are so low though
Needs more tweaking I guess...

Turn off HT. Makes a huge difference.

1.47v seems like a lot to push through a 32nm chip. Is that even safe? The max recommended safe voltage for 45nm is 1.35v

I actually do a bit of video rendering and encoding, so I need the HT on

it varies from chip to chip to be honest. for example, max safe voltage for a a phenom ii x4 940 can be 1.5

that's fine, but that's also why Gflops are a little low. not like you're going to notice it on any real world application though.

i thought max safe for 55nm chips (i7 at least) was 1.55

yeah thats a little high. I would go 1.5v or below if you have good enough cooling...like 70C

Its a bit hard to tell how much these B1 980x's will really take until people start burning out their chips and posting the results here. I would expect 1.45v to be ok and wouldn't hesitate to run that, but id be careful pushing one that was mine higher until others have done so
