Ive got an EX58-UD5 that is only detecting16gb instead of the 24 i have installed. Windows 7 Ultimate says 24 installed 16 usable. all the memory is the same stuff and all is tested and working fine. (corsair vengeance 6x4gb) I have updated to the newest non beta bios (f12)

Hi

Have you just installed more memory ? I am just unsure why this problem has just surfaced.

Did you also leave the BIOS settings on Auto ?

If so that is your problem. You have to compensate for the extra loading on the memory controlller and possibly alter the QPI/Vtt also. The timings will need to be inserted manually too.
