Tried Rampage-IV-Extreme-ASUS-2003.CAP rename to R4E.CAP and roll back USB BIOS Flashback?

Remove all your RAM and video card. Remove the battery for a while and put it back. CLR CMOS, and put back your ram and video card. Boot and check for the result and see if you are back to normal again.
Change is the law of life. And those who look only to the past or present are certain to miss the future.

If a new bios does not offer features you need ??? then why update?? If its stable keep it simple and dont update.

After a full system clear i would try switching to the secondary bios and booting from that to check if the problem still exists it may be a corrupt bios flash. Also check the dimms are seated correctly.

Another option is to use a fat formatted usb stick and do USB flashback with the old 1404 Bios on it renamed to ERALL.rom

@lenehan ; ıts not worked.
@tl@asus ; ıst not worked.
@8pack ; its not worked. i can back 1404 but cant see the ram
