hehe, just finished assembled my dual-core rig. last week
that's all i can get stable with the crappy mobo...
btw, i'm running it on stock hsf, full load temp. 51 celcius,
as for the stepping.. , i forgot the whole code.. but i know it's 0606 production as i remember there's 0606 code on the processor..

*refer to my siggie for more detail info.

if only i got biostar6100 ..` then i'm sure i can touch 2.6 or 2.7 ..
sadly..` i bought this suxxing asus mobo >__<
