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.
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.
According to Intel
CPU spec, DIMM voltage below 1.35V is recommended to protect
®
the CPU.
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:
-
Use a maximum of 3 GB system memory if you are using a 32-bit Windows
-
I nstall a 64-bit Windows
motherboard.
-
