1.7.2 Memory configurations 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 configuration. Any excess memory from the higher-sized channel is then mapped for single-channel operation. • We recommend that you install the memory modules from the blue slots for better overclocking capability. • Always install DIMMs with the same CAS latency. For optimum compatibility, we recommend that you obtain memory modules from the same vendor. • Due to CPU specification, AMD® 100 and 200 series CPUs support up to DDR3 1066MHz. • When overclocking, some AMD CPU models may not support DDR3 1600 MHz 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: - 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. • 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 2.4 Ai Tweaker menu for manual memory frequency adjustment. • For system stability, use a more efficient memory cooling system to support a full memory load (2 DIMMs) or overclocking condition.

Memory configurations
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 configuration. Any excess
memory from the higher-sized channel is then mapped for single-channel operation.
•
We recommend that you install the memory modules from the blue slots for better
overclocking capability.
•
Always install DIMMs with the same CAS latency. For optimum compatibility, we
recommend that you obtain memory modules from the same vendor.
•
Due to CPU specification, AMD
®
100 and 200 series CPUs support up to DDR3
1066MHz.
•
When overclocking, some AMD CPU models may not support DDR3 1600 MHz 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:
-
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.
