This Motherboard uses a socket AM3 that  carries the following features:

  • Accommodates AMD Phenom II/Athlon II/ Sempron processors (Socket AM3)
  • Supports HyperTransport (HT) 3.0 interface speeds

Hypertransport technology is a point-to-point link between two devices, it enables integrated circuits to exchange information at much higher speeds than currently available interconnect technologies.


The AMD 890GX Northbridge (NB) and SB850 Southbridge (SB) chipsets are based on the innovative and scalable architecture with proven reliability and performance.

AMD 890GX:

One x4 A-link Express III interface for connection to the AMD SouthBridge. The A-Link Express III is a proprietary interface developed by AMD basing on the PCI Express technology, with additional Northbridge-Southbridge messaging functionality. It supports the PCI- Gen 2.0 transfer rate of 5 GT/s. and is backward compatible with the A-Link Express Gate II interface.

Supports Two x16 PCI-Express Gen2 Graphics cards link

Fully supports ACIP states SI,S3.S4 and S5

Supports ATI HyperMemory

Supports 16-bit up/down HyperTransport (HT) 3.0 interface up to 4.8 GT/s

AMD SB850:

Compliant with the PCI 2, 3 specifications at 33 MHz

Two Lane PCI Express (PCIe) 2.0 interface supporting up to two general purpose devices. Supported configuration includes 1x2 2x1

Supports five Serial ATA devices with speeds up to 6Gb/s

Integrated USB 2.0 Host controller supporting up to fourteen USB 2.0 ports

Supports integrated RAID 0, RAID 1, RAID 5, and RAID 10 functionality across all 5 ports (RAID 10 requires use of 4 or more SATA ports)


  • Supports DD3 1600 (OC)/1333/1066/800 DDR3 SDRAM with Dual-Channel architure
  • Accommodates four unbuffed DIMMs
  • Up to 8GB per DIMM with a max memory size up to 32GB


  • 7.1 + 2 Channel High Definition Audio Codec
  • Meets Microsoft WLP3.x (Windows Logo Program) audio requirements
