But yeah, I'm at 400 strap and at 2.00D with same voltages and just the changed mch reference above and currently priming in blend mode, and it's gone a bit further that it has before at 333 strap...still feels unstable though (sluggish)

edit: Okay just got a bsod after 15 minutes in blend...ill try more settings....keep em ideas coming

Anyone? I can't seem to get 500 x 8.5 no matter what I do. Prime 95 Small FFT is fine but Blend most of the time will just cause a bsod (says uncorrectable hardware something), and rarely will error. It will error if I leave the MCH reference at .76 (1.20 VTT) and any lower reference will cause a BSOD after 10 minutes of blend. have tried a bit of clock skew but not a lot. im using f8 bios
