2.4.2 Memory configurations You may install 512 MB, 1 GB, 2 GB and 4 GB unbuffered ECC and non‑ECC DDR2 DIMMs into the DIMM sockets. Recommended Memory Configurations Mode Single-Channel DIMM_A1 (yellow) - Populated Sockets DIMM_A2 (black) DIMM_B1 (yellow) - Populated - - Dual-channel (1) Populated - Populated Dual-channel (2) Populated Populated Populated DIMM_B2 (black) - - - Populated • 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. • Due to CPU limitation, DDR2 1066 MHz is supported by AM2+ CPU for one DIMM per channel only. For system stability, when four DIMMs are installed, all DIMMs run at DDR2 800 MHz as the default setting. • It is recommended to install the memory modules from the yellow 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 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 install a 64-bit Windows OS when having 4GB or more memory installed on the motherboard. • This motherboard does not support memory modules made up of 128 Mb chips. • The default memory operation frequency is dependent on its SPD. Under the default state, some memory modules for overclocking may operate at a lower frequency than the vendor-marked value. To operate at the vendormarked or at a higher frequency, see section 3.4 Advanced 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.
