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.
Always install DIMMs with the same CAS latency. For optimal compatibility, we
recommend that you install memory modules of the same version or date code (D/C)
from the same vendor. Check with the retailer to get the correct memory modules.
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
following:
- Install a maximum of 3GB system memory if you are using a 32-bit Windows
OS.
- Use a 64-bit Windows
motherboard.
This motherboard does not support DIMMs made up of 512Mb (64MB) chips or less.
The maximum 32GB memory capacity can be supported with 16GB or above DIMMs.
ASUS will update the memory QVL once the DIMMs are available in the market.
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.
