Sorry, but I had to share my excitement. I haven't tested to see if it's stable yet, but I finally hit 3GHz! The idle is still 35, which is very good for my case.
...WOW, I just noticed my RAM was running at 231MHz... I could've sworn I had a 3:2 FSB:RAM ratio. This is strange; is XP Home just more stable than X64? It would never do this under X64.
EDIT: Aww, I got the "NOT EXACT IN ROUND" errors consistently in SuperPi.
My computer still hasn't restarted yet though!
ASUS A8N32 SLI-Deluxe, AMD Athlon X2 3800+ @ 2.8GHz, eVGA 8800GTS 320MB, 2GB Corsair XMS DDR400, 160GB WD HDD + 320GB Seagate Barracuda 7200.10, AC Freezer 64 Pro, 700W OCZ GameXStream, NZXT Zero :D
I think I've decided to leave... maybe I'll come back sometime.
