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.

• 

Due to Intel

®

 chipset limitations, DDR4 2133MHz and higher memory modules on 

XMP mode will run at the maximum transfer rate of DDR4 2133MHz.

• 

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. Profile 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 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 (2 DIMMs).
