AMD® 785G / SB710
HyperTransport™ 3.0:up to 5200 MT/s for AM3 /AM2+ CPU
2000 / 1600 MT/s for AM2 CPU
4 x DIMM, max. 16GB, DDR2 1200(O.C.)/1066/800/667 MHz, ECC and non-ECC, un-buffered memory
Dual channel memory architecture
*Due to AMD CPU limitation, DDR2 1200/1066 is supported by AM3/AM2+ CPU for one DIMM per channel only.
**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.
