Memory Configurations; Ddr2 Qualified Vendors List - Asus I220GC User Manual

Memory configurations

You may install 256MB, 512MB, 1GB, and 2GB unbuffered non-ECC DDR2
DIMMs into the DIMM sockets.
• For dual-channel configuration, the total size of memory module(s) installed
per channel must be the same (DIMM_A1 = DIMM_B1).
• Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules from the
same vendor. Refer to the DDR2 Qualified Vendors List on next page for
details.
• If you are using a Windows 32-bit operating system (e.g. 32-bit Windows
XP, 32-bit Windows Vista) without the Physical Address Extension (PAE)
support, the system will allocate a certain amount of memory space for
system devices.
• We recommend that you install only a maximum of 3GB system memory
when using a Windows 32-bit version operating system without the PAE.
The excess over 3GB of installed memory will not cause any problem;
however, the system can not use this excess memory space and the
system will display less than the total size of physical memory installed.
• This motherboard does not support memory modules made up of 128 Mb
chips or double-sided x16 memory modules. .
