so how would I go about doing this? Multiply 1.3 * .63 and .67 for my two values?
because i'm not that comfortable poking my DMM around the board to measure VTT/GTL, i work backwards from the know DFI X38 GTL ref volts table and adjust cpu vtt according

i.e. if table says 110/105/85 = 0.812v/0.816v/0.812v then i know if CPU VTT in bios is showing 1.28v then i have roughly 63.4%/63.75%/63.4%

No idea if that's accurate but i use quad superpi/systool pi tests to test and for my QX9650 stability occurs at 1.28v VTT with 115/107/88 for quad pi tests. When it's unstable it just reboots at high fsb.
