Well I wanted to do some PCmark runs with this setup, so I don't even care about stability - all I want is to bench at 4,5-4,6 which that 3848A352 Xeon can handle it its sleep. Thanks for the skew values, will try messing with them a little. Like I said I can't even get 210 BCLk to boot, 205 max. If I raise to 210 with SetFSB it's an instant BSOD as well.
