great stuff eva, posted a question on your other site i4memory. Hope this board plays out for all I could hope for.

Damn ... I think I have another strange voltage problem on my new board...
If i measure with my multimeter the Cpu Vtt voltage the value is around 0.05v less than i set in Bios. For example: the stock value is 1.21v, but my measure show only 1.15v. It´s very strange, because all other voltages measured are absolutely perfect.
The Cpu Vtt is a delicate value, because we must always monitor their exact distance to Vdimm...

You sure it's that low ? maybe psu related as my CPU VTT under reports by 1/10th of what yours does ~0.005v under volts under load.

Did my own tests, PSU = HX1000

1. Vcore over reports slightly in VDROOP Enabled mode, but severely over reports with VDROOP Disabled i.e. 1.23v bios/SG reported = 1.206/1.203v idle/load DMM measured!
2. VDIMM over reports by 0.05v
3. CPU VTT undervolts by 0.012v to 0.014v at idle but jumps 0.009v higher under windows load but still is 0.005v under volted under load compared to what is set in bios. Note: for the requirements for VDIMM to be within 0.5v of Uncore (CPU VTT), it didn't change if you look at under load voltages. Bios reports 1.66v vdimm and 1.21v CPU VTT = 0.45v difference. DMM Measured 1.655v vdimm and 1.205v for CPU VTT = 0.45v difference under load or 0.459v difference at idle.
