1.5.2 Memory congurations

You may install 1GB, 2GB, 4GB, and 8GB unbuffered non-ECC DDR3 DIMMs into the DIMM

sockets.

• Memory module with memory frequency higher than 2133 MHz and its corresponding

timing or the loaded XMP Prole is not the JEDEC memory standard. The stability and

compatibility of these memory modules depend on the CPU’s capabilities and other

installed devices.

• 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 conguration. Any excess

memory from the higher-sized channel is then mapped for single-channel operation.

• We recommend that you install the memory modules from the blue slots for better

overclocking capability.

• 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

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 maximum 64GB 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 efcient memory cooling system to support a full

memory load (4 DIMMs) or overclocking condition.
