Memory conﬁgurations

You may install 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 configuration. 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.

•

Due to the CPU spec., AMD AM3 100 series CPUs support up to DDR3 1066MHz.

With ASUS design, this motherboard can support up to DDR3 1333MHz.

•

When overclocking, some AMD CPU models may not support DDR3 1600 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

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 512Mb (64MB) chips or less

(Memory chip capacity counts in Megabit, 8 Megabit/Mb = 1 Megabyte/MB).

•

The default memory operation frequency is dependent on its Serial Presence Detect

(SPD), which is the standard way of accessing information from a memory module.

Under the default state, some memory modules for overclocking may operate at a

lower frequency than the vendor-marked value. To operate at the vendor-marked

or at a higher frequency, refer to section

3.4 Ai Tweaker menu

for manual memory

frequency adjustment.

•

For system stability, use a more efficient memory cooling system to support a full

memory load (4 DIMMs) or overclocking condition.
