Unlock a DIMM socket by pressing the retaining clips outwards. 2. Aling a DIMM on the socket such that the notch on the DIMM exactly match the notches in the socket. Firmly insert the DIMMinto the socket until the retaining clips snap back in place. 3. 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. 4. 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. 5. Reverse the installation steps when you wish to remove the DIMM module. Notch Locked Retaining Clip 14
