Honestly not that high, but I was just aiming for a stable, cool OC around 2500mhz.
rofl tho....i set my cpu voltage to 1.45, and i've seen it drop to 1.40 (and one time to 1.38) too many times. Never buy a 680w thermaltake psu!!! Junk!
Rig is:
AMD X2 4400+ @ 2.53GHz with Zalman CNPS9500
ASUS A8N32-SLI Deluxe
2GB Corsair TWINX2048-3200C2PT DDR400 PC3200 XMS Platinum memory
1 x BFG 7800GTX 256MB OC
1 x 150GB Western Digital Raptor HDD
Creative Labs Soundblaster X-Fi Extreme Music
Windows XP Pro SP2
I need better cooling though, as I could hit 2.6 and above if the processor would stay cool enough. I think I'll go with an SI-120, but I'm not knowledgeable on the best fan for the win.
