Installing DDRII Modules

1.The memory module has only one notch on the center and will only fit in the right orientation.

2.Insert the memory module vertically into the DIMM slot. Then push it in until the golden finger on the memory module is deeply inserted in the DIMM slot.

Important

You can barely see the golden finger if the module is properly inserted in the DIMM slot.

3. The plastic clip at each side of the DIMM slot will automatically close.

Volt Notch

Important

-DDRII modules are not interchangeable with DDR and the DDRII standard is not backwards compatible. You should always install DDRII memory mod- ules in the DDRII DIMM slots and DDR memory modules in the DDR DIMM slots.

-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.
