    Pretty good Pifast and high speed 1M

    Haven't done 2D in a while, but I did so today with some left over LN2...used a 790i/GTX280 3D installation on a Rampage Extreme lol, so the OS is as crappy as you could imagine.

    CPU is a Q820A593 E8600 cooled with Dragon F1 original...the vcore is...high...as you can see.

    14.59 sec PiFast - 6403MHz



    The Rampage's only weakness is 1M...but anyways...6507MHz is pretty nice to look at

    Neither, I'm 99.999% certain it's a cache latency issue. I think the pre-45nm BIOSes have disabled features that we don't notice but speed up the L1 and/or L2. That's why only 1M and smaller SuperPi calculations get a boost. It's not memory related, as if it were, the boost would apply to 3D and 32M for instance, but it doesn't.

    I agree, Some form of error checking or acceleration feature related.

    Why did you change Fonts on your installation ?

    Very nice runs Gautam!

    46125 PP is possible with Rampage Extreme, didn't try real hard so perhaps even better should be possible.
