y
Always insert memory modules in the

slot first.
y
Due to chipset resource usage, the available capacity of memory will be a little less
than the amount of installed.
y
Based on Intel CPU specification, the Memory DIMM voltage below 1.35V is
suggested to protect the CPU.
y
Please note that the maximum capacity of addressable memory is 4GB or less
for 32-bit Windows OS due to the memory address limitation. Therefore, we
recommended that you to install 64-bit Windows OS if you want to install more than
4GB memory on the motherboard.
y
Some memory may operate at a lower frequency than the marked value when
overclocking due to the memory frequency operates dependent on its Serial Presence
Detect (SPD). Go to BIOS and find the
Memory Try It!
to set the memory frequency if
you want to operate the memory at the marked or at a higher frequency.
y
It is recommended to use a more efficient memory cooling system for full DIMMs
installation or overclocking.
y
The stability and compatibility of installed memory module depend on installed CPU
and devices when overclocking.
