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

[CryptiK]

Hello ppll!

After some weeks of test to get my settings prime aproved i can only do Small ffts 15mts and sometimes more... but i cant get my Volts lower than this need your help!!!

Before i get to other values i want to get Prime Stable on this.

Any input helps! tks!

If that is not an E0 stepping, good luck going higher on that voltage, most top out at around 4GHz @ ~1.42v (real load). You can just try various GTL Refs, start with 0.63x on each one and move up to ~ 0.70x on each one. Whichever gives the longest time in orthos without an error is the best setting. However if you can only pass 15mins without an error, I doubt you can get 100% stable with GTL tweaking. id say your cpu is at its limit.

However you could try increasing the vNB, 1.32 is pretty low for DDR3 and that FSB with a quad. Those boards aren't really built for it so you may need to push it. Try 1.40 vNB.

I also assume you have tested the cpu & ram/NB separately using small FFT, large FFT, bootable memtest & windows memtest? What do you pass/fail? Prime is not the only test you need to run, and even with prime you need to run small & large FFT's. Try to give us as much info as possible or else its very hard to know what to suggest to you ok.

Ok, i have this - 1.4 vCPU, 1.54 CPU PLL, 1.36FSBt with x67GTLREF, vNB 1.57, DRAM CLK Screw A/B to Normal.
So, the idea was, that with more vNB, since i have 4 RAM blocks, i'll fix the mo****f****** lockup. Well, it still do it - just freeze. Is there anything more what i can do? What about SB voltage?

Try pulling out 2 ram modules and see if that makes a difference. if it does its your NB at fault.

Have you tested the ram/NB with bootable memtest & windows memtest?
