X48 Rampage Extreme BIOS

Hi there… anyone ever made a custom BIOS for this old 775 chipset bios? Last version is 1301. Idea is to try and use more RAM, than 8GB max support… going to try 16GB

bios mod wont help you there
hardware must support it
please add a link to your motherboard (or its full name)

Board is an asus rampage extreme

Max ram support state 8gb,but heard some users got 16gb working…
