hmm, im not a big fan on the steppings because they are misleading... You could have the best stepping in the world, made from the best place and still get the crappiest overclock ever... What matters the most is where on the wafer the chip came from... If it came from the center, it'll be a slightly better make, thus giving it a better overclock, if it came from the edge, the opposite... Steppings can't predict that... They are kinda like bios revisions... The manufacturer makes some small changes and what not, and that doesn't always translate into the best oc.... Basically, its all in the luck of the draw.... The SL7KC is made out to be the 4 gig achiever for the 3.2e's, but how many ppl are running their comps at 4 gig? Not that many... If all SL7KC's could do 4 gig, a lot more ppl would be doing it... I have an SL7B8 and that baby can do 4gig... Does that mean that everyone should buy that stepping? Ok ill end my rant...
