Why my TA990FXE only can see two options "Compute 0" and "Compute 1" in BIOS setting? I used AMD FX-4100 4 cores CPU.
Due to AMD AM3+ specification, two cores combined in one module. So you will only see "Compute 0" and "Compute 1" in BIOS menu. Each of them will control two CPU cores.
Will A880GZ support DVI to D-Sub converter to use for display?
Due to motherboard design, A880GZ cannot support DVI to D-Sub converter to display analog display. A880GZ will support analog display only on D-Sub header and digital display on DVI header for the monitor support.
