I think I've finally found the sweet spot for my rig.
The 1008 BIOS allowed me stability at speeds that under 1007 just weren't stable.
I'm currently running:
2.4b (b0) @ 2970 1.8v (reported, 1.75 in bios...Goes to 1.75 reported under load)
Dual Channel DDR412 cl2/2/2/5/4 VDDR 2.65-2x Buffalo 3200 (winbond) CPUZ Calls it Melco 2700
Only thing I did to the mobo was some as3 on the NB.
Case has ~520cfm going through it at max. Usually run @50% on all rhetostats
Some bench pics:
Also have a pic of the case if anyone's interested. Was a lot of work getting all the fans in there correctly. Had to basically redo the entire lower front and rear backplane. Then the usual agp/chimney blowholes.
I'd highly reccomend trying the 1008 beta bios.
Also I've noticed something odd about memory scores between all bioses. At 1:1 (ddr 330) I pull about 3850 in sandra mem bench. PAT brings it to ~3900. But what really struck me as odd is that the bench scores between ddr333 Dual and DDR400 dual are so close. All timings being equal the spread between dual ddr333 and ddr400 is only about 200 points. I kind of hoped for more but until I find a heretofore unknown rich relative who remembers my upcoming birthday this is as good as it's going to get.
PS: PAT has negligible effect on asynchronious mem speeds
