1.5.2 Memory configurations You may install 1GB, 2GB, 4GB, and 8GB unbuffered non-ECC DDR3 DIMMs into the DIMM sockets. • We recommend that you install the memory modules from the blue slots for better overclocking capability. • 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 512Mb (64MB) 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.
