you dont actually change a voltage as in a supply voltage, but there is a GTL voltage which is used as reference to check if a signal on the fsb should be interpreted as a 0 or a 1, and this ref voltage can be meassured.

Ill check where the measuring spots are on different boards and will check how accurate the bios settings are.

so do you guys want the actual reference voltage as a setting or do you prefer the 0.67x vtt setting that asus and others are using?

as for what gtl setting works best, i think even among 9650s theres a difference from cpu to cpu, intel reworked their 45nm process a couple of times and there should be a difference between c0 and c1 stepping as well... but yeah, the settings raja recommends should work well for most 9650s or be close to the best setting

if your reading this, thanks again for the good work raja
