2-9ASUS TS500-E6/PS4

• Always install DIMMs with the same CAS latency. For optimum

compatibility, we recommend that you obtain memory modules from the

same vendor. Refer to the Qualied Vendors List on the ASUS web site.

• You may install varying memory sizes in Channel A, Channel B and

Channel C. The system maps the total size of the lower-sized channel for

the dual-channel or triple-channel conguration. Any excess memory from

the higher-sized channel is then mapped for single-channel operation.

• 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 or more on the

motherboard.

For more details, refer to the Microsoft

support site at

http://support.microsoft.com/kb/929605/en-us.

• This motherboard does not support DIMMs made up of 256 Mb (32MB)

chips or less (Memory chip capacity counts in Megabit, 8 Megabit/Mb = 1

Megabyte/MB).
