Though I need to consentrate on CPU's temps during the bench, I'll bring a friend of mine so to help me out by pooring LN2 in one of the VGAs and I'll have the other one and the CPU......I can't do it alone with 3 x pots and ALL of them at the "edge".....
seems u've already done
yes, controlling 3*pots under LN2 is nightmare and it's mission impossible to running CPU on the edge.

Never even had a chance to get it up to speed under the cascade.

My vapo is a beast though, I can pi, am3 and 2k1 at 4.65ghz, trying for until I get a replacement or bios update.
evga 680i, I dont think the pwm can provide good enough power to cpu.
and award bios is not good for qx6850.
as I've tried on DFI, >333fsb becomes unstable while qx6800 can stable at 400fsb.
you got good cooling there, waiting for ur results
