How to set up GTL Ref Values for 45nm & 65nm

[lowdog]

that can be done :P

Someone give me some example correct values and I can make a quicky console program to give you the mV rating.

The program just needs to know VTT and the fab Process of your CPU right? So you input your VTT, for example mine would be 1.25, and the fab process would be 45nm. So using that formula up there I would need -40mV right?

0) 0.635
1) 0.667
2) 0.635
3) 0.667

Thats the values in order on my mobo (Maximus Formula II) so I need to set 1 and 3 to -40mV right?

Correct, thats how I have mine set up as well.


Something interesting btw;

I had my Q9650 @ 4GHZ (9x450) with 1.28750 vcore, I had FSBTV-1.12v, NB-1.12v, PLL-1.51, LLC enabled and all other volts on one notch up from there lowest values. It was prime/linpack stable but I couldn't lower the vcore 2 notches below this setting or it would start to become flakey. CPU GTL's were 0 auto, 1 -40, 2 auto, 3 -40.

After reading here I decided to try something. Mobo MF2

I raised my FSBTV to 1.29v (which is now above my vcore) and I raised NB to 1.2v, I left the CPU GTL's as they were and left all other volts as they were as well...................then I droped my vcore down to 1.2500v (which is about 6/7 notches down) and the system is rock solid prime/linpack stable.

I'm useless at math and remembering tech terminology but with the first settings I think things fell below the .80 - 1.0 volt margin and were around the mid .7 setting.

After changing values the margin moved up over the .8 barrier and therefore enabled me to lower vcore for some reason. Probably an incorrect assumption as to why I could lower vcore by so much but perhaps there is some validity to it as well.
