Hello guys new member here I built my latest rig with these parts.

C2D 2.66ghz 1333fsb
Asus P5E Mobo with bios 501
2gig Crucial Ballistik@DDR800
Asus 8800gts (G92)
Corsair 620w PSU

I looked up the Vdimm pin online and measured mine on a unused Dimm slot on the mobo (Pin-64) with my DMM.

With the bios set to 1.86 I was reading 1.917 at the pin under full load
+/- .002v

So the mobo is indeed overvolting the ram by .057 volts.

I wonder if Asus will be paying for peoples Ram if they crap out due to overvolting on this issue?

Hope this helps
