1.4 System memory

1.4.1 Overview

This motherboard comes with four Double Data Rate 3 (DDR3) Dual Inline Memory Module

(DIMM) sockets. A DDR3 module has the same physical dimensions as a DDR2 DIMM but

is notched differently to prevent installation on a DDR2 DIMM socket. DDR3 modules are

developed for better performance with less power consumption. The gure illustrates the

location of the DDR3 DIMM sockets:

Channel Sockets

Channel A DIMM_A1 & DIMM_A2

Channel B DIMM_B1 & DIMM_B2

1.4.2 Memory congurations

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

sockets.

• 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.

• 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:

- Use a maximum of 3GB system memory if you are using a 32-bit Windows

OS.

- Install a 64-bit Windows

OS if you want to install 4GB or more on the

motherboard.

• This motherboard does not support DIMMs made up of 512 megabits (Mb) chips or

less.

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

timing or the loaded X.M.P. 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.

• The maximum 32GB memory capacity can be supported with 8GB or above DIMMs.

ASUS will update the memory QVL once the DIMMs are available in the market.
