It may be down to the slots that you have the memory in. Make sure that they are in the correct slots for dual channel.

The only thing I can suggest is to put the BIOS back to the earlier version or try version F6

If I back BIOS on F6 or F5, than BIOS wouldn't recognize my AMD Phenom II X3 720 BE CPU!!!

I think that you need to contact GTS and dump it in their laps. It sounds like a BIOS problem that will only be cured by an update.

I recently updated my BIOS to F9 to accomodate my Phoenix ll x4 940.
In my BIOS I have the option to use 'ganged' or 'unganged' modes, it state that unganged is slightly faster.
Phoenix processors have two memory contollers, in unganged mode the work independantly on each memory module.
In ganged mode the work together in interleave mode.
providing you have matched modules you should still be in 'Dual' modeP
Chech with CPUZ.
Hope this helps'
