Chapter 1
• Due to the memory address limitation on 32-bit Windows ® OS, when you install 4 GB
or more memory on the motherboard, the actual usable memory for the OS can be
about 3 GB or less. For effective use of memory, we recommend that you do any of
the following:
a) Use a maximum of 3GB system memory if you are using a 32-bit Windows
®
OS.
b) Install a 64-bit Windows
®
OS when you want to install 4 GB or more on the
motherboard.
c) For more details, refer to the Microsoft
®
support site at http://support.microsoft.

• 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.
• 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.
• For system stability, use a more efficient memory cooling system to support a full
memory load (4 DIMMs) or overclocking condition.
• Always install the DIMMS with the same CAS Latency. For an optimum compatibility,
we recommend that you install memory modules of the same version or data code
(D/C) from the same vendor. Check with the vendor to get the correct memory
modules.
Memory configurations
You may install 4 GB, 8 GB, and 16 GB unbuffered and non-ECC DDR4 DIMMs into the
DIMM sockets.
