SLACR and OL9UM this is the stepping. the older stepping does not allow for much over clocking. I have the newer stepping and i was able to over clock to 3.4GHz with thermalright extreme 120 heatsink and a 120mm fan. i could have pushed it more but didn't want to risk burning up a new chip. i have it set to 3.0ghz and it's been running perfect for the last 6 months or so.


SLACR is the new G0 stepping. make sure you get this version for future OCing potential. also don't get that zalman. the thermalright extreme 120 beats it in every test and it only costs about $10 more

I got mine from the above link with a scythe s-flex 1600rpm fan and you can barely hear the damn thing. or you can save the $15 bucks and not OC it until you are ready. you can oc to about 2.8-3.0 even without the fan. fan just gives you extra insurance or allows you to oc higher.
