Also, can you raise GTL Ref above 0.67x? I have seen some guys with C0 stepping 9550's needing around the 0.68x - 0.73x mark for 4GHz, but some also need around 1.42v load for stability at 4GHz.
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?
