Yeap, until you run 2.1 vdimm and fail, you don't have much of an argument. Besides,other factors like high fsb and improper NBV and timings could also be factors. Give a little higher cpu volts too, just to eliminate the possibility of that being an issue.

I highly doubt that PL <= 7 is reachable above 600mhz on ram without much volting MCH/RAM.

Ive already done that with success and with using much lower nb,ram volts like A-Grey. Thats the prob...

You can't compare volts, some sticks require less - some more. I would start with 2.3v on ram.
