-DDRII modules are not interchangeable with DDR and the DDRII standard is not backward compatible, you should
always install DDRII memory module in the DDRII DIMM slot and install DDR memory module in the DDR DIMM slot.
- In dual-channel mode, make sure that you install memory modules of the same type and density in different
channel DDR DIMM slots.
- To enable successful system boot-up, always insert the memory modules into the DIMM1 first.
