yeah i mainly use 1.57v Uncore, IOH is actually best for me at around 1.26-1.28v. I've been using 117MHz PCIe but i can use up to 126MHz i think or maybe 128Mhz cant remember.............didnt seem to make a difference
as you said you can run uncore even higher which is very encouraging for high NB speeds
i also found CPU Skew 500ps can help in some situations ~when fighting for the last MHz
i've run PCI and PCIe Nvidia card
also single and Xfire ATI 4870 :up:
have you run 3D
what is your highest bus clock stable in 3D?
i'm at around 229 with this chip benching everything and 232MHz for 32M SuperPi
