Well, I remounted my block and got a decent drop in temperatures even with a tad more voltage. Still, the stuff that comes preapplied to these Corsair H100i's must not be all that bad to allow for 5.0GHz on an SB-E.
5.1GHz
BTW...Grooveriding, what kind of voltage do you have to run at 5GHz?
I think about 1.48 or so, that is an old screenshot from when I was playing around with the chip I have now, so I'm not 100% on the voltage or what it would take now to get a bootup at 5ghz.
I have a pretty nice chip, it does 4.8 @ 1.38, which is really good for SB-E. I can't say that the 5ghz is stable though, never tried Linx on it, etc.
Cinebench is the CPU benchmark equivalent of what Unigine Valley is for GPUs; you can run it on a completely unstable overclock otherwise
Basically if you can boot in to Windows without a crash you can run Cinebench.
I'll try a 5.2 or something later today and see if I can get it to pass.
