Well i had a try on tekjunkie settings on my QX9650:
QDR/RAM=1780 Unlinked
PCIE1/PCIE2 = 100
SPP<-> MCP= Auto
vCORE=1.375(1.344 in windows per cpuz)
Loadline =Enabled
vTT = 1.28
PLL=Auto
vDIMM=1.9 (Manually put the stock voltage for your ram)
vSPP =1.46
vMCP = 1.55
CPU GTL_REF0 = -29mV
CPU GTL_REF1=-32mV
But QDR/RAM was set to 1800 Linked and Sinked.... and for the first time i was able to boot and load windows at 1800FSB on my QX9650



The problem is that i cannot finish Super PI and system seems to have some minor instability. In fact i forgot to enable Loadline Calibration and my memory is runnig at 1800Mhz 7-7-7-16 1T at 1.84V , and this, may be the cause...

But, for me, this seems the way to go i will work on his settings next days to see if i can run at 1800FSB with system stable and complete Super PI 32M without errors.

For now im limited with my NB temperatures that reach 61-63º under load, and this might be a problem for me, i will have to take the board out and apply some MX-2 grease on the NB and SB cooling blocks, and add a side fan to directly blow air to the NB, only then i will make more tests.
