With ASUS design, this motherboard can support up to DDR3 1333MHz. **Due to OS limitation, when installing total memory of 4GB capacity or more, Windows® 32-bit operation system may only recognize less than 3GB. Hence, a total installed memory of less than 3GB is recommended. ***Refer to www.asus.com for the memory QVL (Qualified Vendors Lists).

AMD® 890FX Chipset is designed to support quad PCI Express, so in essence this chipset is far from tame. Not only do we have great power on the graphical side of things, but this chipset also fully supports the new AMD X6 series of processor. Great system performance and overclocking capabilities.

Also worth mentioning is that the AMD® SB850 Southbridge natively supports next-generation Serial ATA (SATA) storage interface, this gives users the potential of up to 6.0 Gb/s transfer rates. Right on the pinnacle of innovation, 6G drives will soon be the mainstream interface on the SATA side of things. Remember, this is double the bandwidth of the traditional SATA drive bus system.
