Next week I'll receve an Opty 2350 and 2x2Gb PC2-6400 reg memories.
I still have to learn how to flash the modified bios into my board (WS)
However i think that the 0.501 bios from asus website is not working due to an incorrect flash.
I think that before using the asus bios you've to flash the older
tic tac bios, after that you can flash the 0.501.
