Asus P8H61-M2/TPM/SI - Manual (Page 16)

ASUS P8H61-M2 Series 1-4
1.4.2 Memory configurations
You may install 512MB, 1GB, 2GB, and 4GB unbuffered non-ECC DDR3 DIMMs into the
DIMM sockets.
• You may install varying memory sizes in Channel A and Channel B. The system maps
the total size of the lower-sized channel for the dual-channel configuration. Any excess
memory from the higher-sized channel is then mapped for single-channel operation.
• For dual-channel configuration, you can:
-
Install the memory modules from the blue slots;
- Install two identical DIMMs in DIMM_A1 and DIMM_B1; or
- Install four identical DIMMs in all four slots; or
- Install one identical DIMM pair in DIMM_A1 and DIMM_B1 (black) and another
identical DIMM pair in DIMM_A2 and DIMM_B2 (blue).
• 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 either 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 memory on
the motherboard.
• This motherboard does not support DIMMs made up of 256 megabits (Mb) chips or less.
