Memory configurations
You may install 256MB, 512MB, 1GB, 2GB, and 4GB unbuffered ECC and
non-ECC DDR2 DIMMs into the DIMM sockets.
•
For dual-channel configuration, install identical DIMMs in DIMM_A1 and
DIMM_B1.
•
Always use identical DDR2 DIMM pairs for dual channel mode. For
optimum compatibility, we recommend that you obtain memory modules
from the same vendor.
•
When you install a total memory of 4GB or more, a Windows
operation system may only recognize less than 3GB. Hence, a total
installed memory of less than 3GB is recommended if you are using a
Windows 32-bit operation system.
The motherboard can support 8GB physical memory on the operating system
listed below. You may install a maximum of 4GB DIMM on each slot.
