Just read the whole thread start to finish - well done Cryptik for such an informative topic.

For me I have noticed some conflicting posts and would like some confirmation. Also, some of the terminology can be confusing.

With a 45nm CPU the GTLs are negative so when talking higher and lower values then mathematically that means closer to zero or positive values for higher and for lower values a more negative value is needed ??!!.

If something is controlled by a formula then it beats me as to why the bios cannot calculate this. I have a 45nm CPU so my GTLs should be negative which is partly backed up by my bios having increments of 5 in the negative range and increments of 10 in the positive range. Is that intentional or just luck ?.

I use a VTT of 1.4v so my CPU GTL should be -45mv.

So where I have read that NB GTLs are generally higher than CPU GTLs I need to look towards zero or a positive number.

Could someone please clarify on a quad core which GTLs correspond to die 0 and die 1 ?. One post said GTL 0 & 1 for die 0 and another GTL 0 & 2 for die 0. I also read a post that said GTLs 0 & 2 are generally higher than 1 & 3, if this is the case is the calculated value of -45mv the highest or lowest value ?.

For example :-
GTL0 -35mv (die 0?) - higher than calculated = smaller negative
GTL1 -45mv (die 1?) - calculated value
GTL2 -35mv (die 0?) - higher than calculated = smaller negative
GTL3 -45mv (die 1?) - calculated value
(please correct where appropriate)

Sorry for such a long post but thanks in advance for any help.
