So far the best I've been able to do is 2.08GHz at 160MHz FSB

, so today I took off my heatsink to find out what I really have under the hood, as it were. So I find out my cpu is a AXDA2100DUT3C-AIUHB0304MPMW :D . Word on the web is this pedigree can be a great overclocker if I bring up the Vcore, so I did manage to do the socket wire trick to set the Vcore to 1.80V. I debated about changing the multiplier at the same time, but decided to leave it at 13 for now.
BTW, it was a very hot day her today - over 90F (32C), so I cranked her up and waited to see what happened. She posted fine at 166 but not at 180, so now we're cruisin' at 172FSB setting giving me 2236MHz, with cpu temp at 50C working at 100%. I'll try more settings later. Hope to get over 2.4 gigs.
Anybody else have this cpu or something similar? What Vcore/multi/fsb works best for you?
