ASUS says that existing 990FX-based motherboards all support the new flagship AMD FX-9000 Series processors at memory speeds up to 2400MHz, without the need for a BIOS update. The ASUS Crosshair V Formula-Z, Sabertooth 990FX R2.0 and M5A99FX Pro R2.0 motherboards all feature AM3+ Socket with full support for AMD?s FX-9370 and FX-9590 processors. With eight-cores and unlocked clock speeds up to 5GHz, the FX-9000 Series requires incredible amounts of power and generates considerable heat ? AMD recommends a 1200W power supply and liquid processor cooling.

Existing ASUS 990FX motherboards also support rock-solid stability at memory speeds up to 2400MHz with selected DDR3 DIMM kits.
