Asus M5A78L-M USB3 User Manual

1.7.2 Memory congurations
You may install 512MB, 1GB, 2GB, and 4GB unbuffered ECC and 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 conguration. Any excess
memory from the higher-sized channel is then mapped for single-channel operation.
• Always install DIMMs with the same CAS latency. For optimum compatibility, we
recommend that you obtain memory modules from the same vendor.
• We recommend that you install the memory modules from the blue slots for better
overclocking capability.
• AMD
®
FX™ Series CPU on this motherboard supports up to DDR3 1866MHz as its
standard memory frequency.
• Due to the CPU specication, AMD
®
100 and 200 series CPUs support up to DDR3
1066MHz. With ASUS design, this motherboard can support up to DDR3 1333MHz.
• When overclocking, some AMD CPUs may not support DDR3 1600MHz or higher
frequency DIMMs.
• 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
followings:
- Install a maximum of 3GB system memory if you are using a 32-bit Windows
®
OS.
- Use a 64-bit Windows
®
OS if 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.
