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

[mikeyakame]

Why there isn't NB/CPU clock skew in RF 0410 BIOS? Or it's MoBo function and my P5E X48@RF doesn't have it?

I need to ask something - is VTT tight just with CPU or this voltage have something to do with the NB? I'm asking this, because i have trouble with RAM, i try it at 1130 (it's 1100 by default) and i got errors sec after starting memtest. vNB and vDIMM doesn't help, so, there reason is somewhere else.

If hardlocks are cause by fsb wall, mine is 470. Even 1mhz up and it locks in windows. So far, the only think, that helps are VTT and vNB.

Because Asus bios engineers too lazy to add it. It was added to P5E3 Premium and P5E64 Evo as far as I know. Rampage Extreme came with the option already there, and all P5Q bios have this too. We drew the short end of the straw it seems my friend.

Vtt and Vnb can help to a point, but from there it's clock skews and fine independant gtl adjustment which we have neither of.

Calling it a wall just simplifies the actual explanation of the problem.

From what I can make out, the "wall" itself manifests mostly from excessive skewing between independant clock waves within the scope of the MCH and CPU, which on top of becoming dirtier from jitter, external interference, ringback, etc as bus frequency, cpu frequency, cpu multiplier rises. It can be as minute as one of the clock signals for either die becomimg too dirty and slightly skewed more than the other and you will experience a "wall" or hard system locks. This is probably just a breakdown of inter-die communications or cross-bus comms, or even phase cycle timing going out of scope.

This is the simplest I can explain what appears to me to be actually happening.

I can reproduce the "fsb wall" on a P45 chipset just with cpu/nb clock skews alone and go between completely stable at high FSB on a Quad Core to near instant cpu load onset hard locks. This is the concrete proof I base my conclusions on.
