Intel Core 2 Extreme QX6850
Abit IP35-PRO (Latest bios)
Chaintech Apogee GT PC8500 4x1gb (Link)
Antec Atlas (550w PSU) Link
Samsung 320GB SATAII
Samsung 20x SATA DVD-RW

OK, i have installed windows with 4gb and it was all fine...
i then reboot after i finished installing all the latest drivers etc and i the computer freezes after about ~2mins.

i then decide to run a memtest with the 4gb, and it errors like crazy after about 30mins..

I have

- upped the volts from 1.8-2.1v
- changed timings to 5-5-5-12
- ram is running below spec (ddr812)
- upped mch to 1.29v
- tested 2x1gb kits for hours (both kits test fine by themselves)


I have no idea wat to do, this is urgent and im all outta ideas

first of all...win xp sp2 32 bit does not support 4G's of memory.

second: you need to up the vdimm to about 2.25 to 2.3v

third: change your dram timming to 5-5-5-18(tRAS..or higher) and "tRC" to 42(or higher)

fourth: mch needs to be at 1.4x voltage minimum.
