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

[Cibic]

There's no hard and fast rule to this, You can feel free to experiment with every combination of the GTL Refs. For example I set +20mv for all my GTL Refs the other night doing some testing, you are not going to hurt anything unless you have a very high Vtt and the Vref goes over 1.10v.

You can try for example, +50/+10/+50/+10 or +50/+20+/+50/+20 or +50/auto/+50/auto or +40/-5/+40/-5 would give you your ~46mv difference if you find that to work better.

(*)I tested my CPU on prime95 small fft's on 3.6GHz 1.42v 9x multi at 1600FSB and passes 8 hours.

Ram at stock, memtest 8h pass. Still get freezing on blend.
I have been at this for a year now, only thing left is gtl refs.

Raised voltage to sensible levels but still higher than needed.

I've tried from +50/+10/+50/+10 to +90/+50/+90/+50
tried minus too +30/-20/+30/-20
core 0/3 from 2/4 always 40 difference. If I'm out of the calculated result i get instabilities even sooner.

But I always leave the NB at +50 (+46 needed,calculated).

I need to know this:
if I get bsod and restart means is the CPU gtls(*)?
If I get freezing is it the NB gtl?

Also should I decrease or increase the NB gtl? VTT is at 1.49v, NB is at 1.5v
Trying +80mv now, all the way from +50mv are unstable for me. Strange, they take almost the same amount of time to freeze or gimme the the BSOD then freeze.
