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

[spoof]

Yeah mate it's exactly the same as for the cpu.

GTL Ref x Vtt = NB Vref

If you have +/- mv settings use them to alter the ratio.

For example my NB GTL Ref = 0.64x

So 0.64 x 1.2v = 0.768v

So, how much should be NB Vref? Cause i can get stability with 1.49vNB and 0.64 - not sure if this is safe.
