Is this true for the P45 also. From experimentation (system specs below). I was able to get stable at FSB 425 with vNB 1.28 and then drop one step to 1.27 by changing NB GTL to +30 from auto (aiming for about 0.67) and at 450 to drop again from 1.29 to 1.27 by going to +40 from +30. Each time I was stable (8h OCCT RAM) at the higher vNB and not at one step down, which became stable by altering the GTL up - whereas most posts here seem to suggest 0.58-0.6 is ideal GTL target for NB - which as I understand it would require a negative GTL offset as the default on this board is 0.64.i agree with that guy too! nb gtlref calculation is not exactly a science, well even less so than the cpu counterpart. i have a few simple guidelines i follow when setting the nb gtlref value...
1. you will almost never need to use a higher value than cpu gtlref unless you are attempting to use fsb frequencies which don't want to be used! if thats the case change the fsb frequency it's an actual solution to your problem! its so much easier than jacking voltages all over the place to find stability when it's in fact hiding from you because it lies about its good looks and fun times to feel a sense of importance!
CPU is on auto/-40/auto/-40 aiming for 0.63 on all.
Confused!!
