Memory configurations
You may install 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 configuration. Any
excess memory from the higher-sized channel is then mapped for single-channel
operation.
•
According to Intel CPU spec, DIMM voltage below 1.65V is recommended to protect
the CPU.
•
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
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:

•
This motherboard does not support DIMMs made up of 512Mb (64MB) chips or less
(memory chip capacity counts in Megabit, 8 Megabit/Mb = 1 Megabyte/MB).
•
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.
•
Due to Intel
mode will run at the maximum transfer rate of DDR3 1600MHz.
•
For system stability, use a more efficient memory cooling system to support a full
memory load (4 DIMMs) condition.
