DFI Launches DK 790FXB-M3H5 AM3 Motherboard With the Lanparty DK 790 FXB-M3H5 DFI introduces a motherboard for AM3 processors. For the new board a 790FX chipset and a SB750 Southbridge are used. Thus the DK 790 FXB-M3H5 supports all Phenom II CPUs and up to 16 GiByte DDR3 RAM in four memory slots. Furthermore DFI integrated three PCI Express 2.0 x16 slots and support for CrossfireX. Due to a digital 4+1 phase PWM the DK 790 FXB-M3H5 might also be interesting to overclockers. The "Replaceable” design allows you to remove and replace the Northbridge cooler. Besides six SATA II and twelve USB 2.0 ports the DFI Lanparty board also offers a gigabit LAN port and two IDE connectors. A debug LED informs about the current stability of the board.
