Hardware Installation Process
Installation Step:
1. The DIMM slot has a notch, so the DIMM memory module can only fit in one direction.
2. Insert the DIMM memory module vertically into the DIMM slot. Then push it down.
3. Close the plastic clip at both edges of theDIMM slots to lock the DIMM module.
4. The processor supports 64-bit mode and 128-bit mode configuration of the DIMMs. In 64 bit mode,
only DIMM 0 and 2 can be populated. Possible combinations of DIMMs in 64 bit mode are listed in
Table 1. In 128 bit mode, minimum of two DIMMs is required to create the 128 bit bus; therefore,
DIMMs can only be populated in even numbered pairs in slot 0 & 1, and 2& 3. Each logical DIMM
must be madeof two identical DIMMs having the same device size on each and the same DIMM
size. Regardless of mode, DIMM must be populated in order starting at the farest slotfrom the
processor. Table 2 & 3 shows the possible combination of DIMMs for 128 mode. Not all possbile
combinations are listed in the tables.
5. Installed DIMMs must be the same speed and must all be registered. For a list of suuported
memrory, please refer to the table of previous page.
6. Reverse the installation steps when you wish to remove the DIMM module.
