It has support for DDR667 -- 4 x DIMM, max. 8GB, DDR2 800/ 667/ 533.
I don't see any downloads for it, nor do I see its name exactly to search at ASUS support, but the motherboard does come with the user manual. You can also try setup defaults in the bios, it'll reset everything including the dram settings. I would recommend to try it set manually 667Mhz 5-5-5-15.
It's me after a week of tring to fix things I gave up.
I have tried million of metods but nothing seems to work.
All metods that you said didn't work.
Now i installed a new OS(Vista -> Xp) but i get error from 5 to 5 minutes.
I got BSOD even from browsing on internet.
Here is my dump file : 2shared - download Minidump.rar
Here are some screenshots : ImageShack Album - 4 images
Please don't tell me to remove a stick of RAM because that didn't work.
The above screen shots reveal you have 1024Mb Kingmax 800mhz in slot#3 and 2048Mb Nanya 667Mhz in slot#4.
The problem is that the sticks are not matching each other's specs and this is why you are getting blue screens. Remove Kingmax and put the Nanya stick in slot#1. Then load setup defaults in the bios.
