Due to the memory address limitation on 32-bit Windows
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

•
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 2.5 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.
