Installation Tips

Open the two plastic clips of memory slots then push down the module

vertically into the slot. See to it that the hole of the module fit into the notch of
the slot.

The two plastic clips will automatically close if the memory module is fitted in a

proper way.

We suggest that priority given to DIMM1 and DIMM3 in multi-DIMM installation.

System won’t start when you only install memory DIMM in DIMM2 and DIMM4.
