I still believe that ASUS need to add more DDR3 RAM support for their LGA775 Rampage Extreme X48 based boards. 4GB DIMMS seem to be the norm these days and it would be nice for ASUS to upgrade the RAM compatibility.
Not only that but the ICH9R ROM and Marvell ROM's desperately need upgrading too.
Oh and the QX9650 CPU RATIO COLD BOOT issue needs resolving as well.
Thankfully ASUS support have provided me with a BIOS not to be issued externally which fixes the QX9650 manual multiplier cold boot issue and the ICH9R ROM, however ASUS need to issue these fixes for everyone.
I do appreciate LGA775 is old, but that is no excuse to leave the platform with an unfinished BIOS.
Please fix the remaining issues with 8GB and Quad Cores, MSR errors in BITS, update the ROMS and also add compatibility for 4GB DIMMS.
