Memory configurations
You may install 1GB, 2GB, and 4GB 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:
- 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.
• 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.
