How to use

Power off the system and unplug it from the mains. Open the chassis according to the system manufacturer’s instructions. Locate the appropriate 288-pin DIMM slot on the motherboard and align the module with the slot key. Press firmly and evenly until the module clicks into place and retention clips engage.
