My GTL's are set to a + value any change and it fails prime and linpack
The values dont match the formula I know but they work so I dont argue with them

CPU Voltage : 1.3875
CPU PLL Voltage : 1.53975
FSBT : 1.33850
DRAM Voltage : 2.095
North Bridge Voltage : 1.39150
South Bridge Voltage 1.5 : 1.5
South Bridge Voltage 1.1 : 1.1

CPU GTL Reference 0 : +30mv
CPU GTL Reference 1 : +20mv try +30/+40/+50mv
CPU GTL Reference 2 : +20mv try +30/+40/+50mv
CPU GTL Reference 3 : +30mv
North Bridge GTL Reference : AUTO
DDR2 Channel A REF Voltage : AUTO
DDR2 Channel B REF Voltage : AUTO
North Bridge DDR Reference : AUTO
If core 2 always fails, try increasing the GTL Ref for that core. I believe it is 'core 1' (as 4 cores are denoted 0,1,2,3) but also try increasing it on 'core 2' it *should* make a difference.
