Here's a look at the specifications of this motherboard:
CPU Phenom™ X4 / Phenom™ X3 / Athlon™ X2 / Athlon™ / Sempron™ processors
(socket AM2+ / AM2)
Compatible with Phenom™ II / Athlon™ X4 / Athlon™ X3 / Athlon™ X2 (AM3 CPU)
Supports 45nm CPU
AMD® Cool 'n' Quiet™ Technology
Chipset AMD® 790FX / SB750
System Bus Up to 5200 MT/s HyperTransport™ 3.0 interface for AM3 / AM2+ CPU
2000 / 1600 MT/s for AM2 CPU
Memory 4 x DIMM, max. 16GB, DDR2 1066* / 800 / 667 MHz, ECC and non-ECC,
un-buffered memory
Dual channel memory architecture
*Due to AMD CPU limitation, DDR2 1066 is supported by AM2+ / AM3 CPU for one
DIMM per channel only. Refer to
www.asus.com for the memory QVL (Qualified Vendors Lists).
**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.
