Boards ASUS P5B Deluxe (P965+ICH8R , 4 GB MAX ) & ASUS P5K Premium/WIFI-AP (P35+ICH9R, 8 GB MAX) have option in BIOS kind of :- Advanced ->ChipsetSettings->NorthBridge->Memory Remapp : Enabled (4GB & 8GB corespondently) or Disabled (3 GB avalilable on P5B Deluxe, ability to load CentOS 5.0 (x86_64), F7 (x86_64) with usual kernels ) I never disabled it on P5K Premium/WIFI. The most recent F7(64 bit) install ran smoothly with this mentioned option enabled. > > Of cause this also depends on the chipset used on > the > mainboard, there are chipsets that can't access > memory > at addresses >= 4GB.
