QX9650
Do you have a BSOD?

Thanks I expected you used a QX9650 but just had to be sure. No after POST (before loading windows) I get a black screen w. white letters telling windows could not start because xxxxx.xxx file was missing or corrupt.

Right now I have been Priming for more than 2.5 h with these settings:

400x9.5, mem 1600
7-7-7-20 1N

CPU voltage: 1.4
CPU GTL: 0.65x
PLL: 1.50
FSB TV: 1.3
DRAM: 1.8
NB: 1.45
NB GTL: x0.67
SB: 1.2
clock O-C V: Auto
Load line cal: Normal (Performance will give me BSOD)

But with your settings (FSB 450) I could not boot to Windows even when setting the multiplier to 7 and leaving CPU voltage at Auto (to rule out my CPU can not handle 4.05 GHz)

I have notised that others (e.g. SIOUX) uses NB volt of 1.65-1.69 for FSB 490-505 on a 45 nm quad but I get almost instant freezes in Windows when setting NB voltage > 1.61.

Based on your timings I assume you are running 2x1GB memory. I suppose it is more tricky to run the higher density 2x2GB memory at 1800 (even though my memory are rated at that speed there is no warranty that the motherboard can handle this). However, SIOUX had no problems running 2x2GB memory on this board so I still expect this is posible for me, see: http://www.xtremesystems.org/forums/...=187371&page=3

Which subtimings and command rate are you using Sav? What about the other DRAM-related setting e.g. DRAM static read/write control (mine are all on Auto so far).

Thanks again Sav
