So, I finally decided to test how well my DFI DK X48 T2RSB+ could clock my Q9300. I am taking the slow and steady approach advocated by the posted guide. I've set some low goals and decided to start with 3.2 (426FSB). After mucking with VTT and NBcore a bunch I have come up with a stable overclock that puts the Vcc at nearly 1.3v. I've seen these 45nm chips get lauded so much for their low voltages so I'm just concerned I might be missing something if I have to raise Vcc so much to get 200Mhz out (I had previously been rock stable @ 3Ghz Vcc 1.2, everything else at its lowest setting).
I haven't optimized temps yet (running a Domino ALC at its lowest setting so far) so is it possible that any instability is coming from high temps? (Load temps read 70-73 on CoreTemp, 62 on the ALC's display) In other words, if I cooled it more aggressively, would I be able to lower Vcc?
This is my first time being really systematic at this, so far I am impressed with my Corsair XMS2 2x2GB kit, it plays real nice at just 1.8V and am obviously quite happy with the mobo which seems to love FSB. Maybe I'll find something funner to put inside it and clock up.
