You can install either single- or double-sided modules on this board. Each DIMM can
work respectively for single-channel mode and dual-channel mode. Please note that the
same type and density memory modules are necessary while using dual-channel,
otherwise it may cause system instability.
Please refer to the following table memory configuration.
NOTE:
While using ECC type memory, it will take longer time to post. Due to the manner in which it
counts the memory and has to write zero’s to every bit of the stick before progressing through the
POST.
3.5 – Memory Installation Procedure
When installing memory modules, make sure the modules align properly with the memory socket.
There should be keys (small indents) on your memory modules that fit according to the keys in the
memory socket. DDR modules and sockets have only one key, which is slightly near the center of
the module/socket. The method of installing memory modules is detailed in the following
diagrams.
