Following ECS, ASRock will be one of the first ones to be out with an AM3 socket motherboard supporting the upcoming 45nm processors by AMD, as well as support for the newer DDR3 memory technology. The M3A790GXH-128M motherboard has been pictured by the guys at OCWorkbench. It is based on the AMD 790GX + SB750 chipset and features 128 MB of DDR3 Sideport graphics memory for the onboard Radeon HD 3300 IGP.

The most significant feature of this motherboard is support for up to 16 GB of DDR3 1333/1066/800 MHz memory. What's even more interesting according to the specifications OCW listed, is that the motherboard supports a range of AM3, AM2+ as well as AM2 processors that include Sempron and Athlon64, while featuring only DDR3 memory slots. There are three PCI-Express x16 slots ,which depending on the devices installed, arrange in lane configurations of (x16, NC, x4) or (x8, x8, x4). The IGP provides output from DVI, D-Sub and audio-routed HDMI ports. The SB750 southbridge provides six SATA II channels. The board also integrates a high-grade 7.1 HD audio CODEC, the Realtek ALC 889, which comes with a rated SNR of 110 dB. Overall, the motherboard features a simplistic construction. The cooling isn't extravagant, with heatsinks for the chipset. The CPU is powered by a 4+1 phase power circuit whose MOSFETs have no heatsinks. Pricing and availability isn't known at this point in time.
