1.4.2 Memory configurations You may install 512MB, 1GB, and 2GB unbuffered non‑ECC DDR2 DIMMs into the DIMM sockets. • Always install DIMMs with the same CAS latency. For optimum compatibility, it is recommended that you obtain memory modules from the same vendor. • Due to the memory address limitation on 32-bit Windows® OS, when you install 4GB or more memory on the motherboard, the actual usable memory for the OS can be about 3GB or less. For effective use of memory, we recommend that you do any of the following: - Use a maximum of 3GB system memory if you are using a 32-bit Windows® OS. - Install a 64-bit Windows® OS when you want to install 4GB memory on the motherboard. • When you install 4GB memory on the motherboard, the memory that the system can detect is less than 4GB. • This motherboard does not support DIMMs made up of 256 megabits (Mb) chips or less.
