If you compare the original BIOS to the MOD BIOS than you know that ASUS did some work on the option ROMs and made the DRAM CLK Skew on Channel A Delay 100ps and DRAM CLK Skew on Channel B Advance 100ps the default for the original BIOS but didn't fix the stability problem.

Managing option roms is not Asus job... they just intergrate what manufactures provides to them. I personaly think that option rom changing VITAL things like memory timings is a fluke (or design flaw) in the long run... option roms should have one function only, and that is to provide support and compatiblity for certain integrated hardware and not change functions that you might not want to be changed... But since this could be design flaw (and mobo manufacutes knows about it), this might be a reason asus is so reluctlant to update them, because they know it might effect stability. Funny thing is, all mobo manufacuters that actualy updates option roms every once in a while have award or efi bios. Dont think i ever saw mobo with AMI bios that manufacture also updates option roms... coincidence? could be... or not :<
