Chapter 2: Installation 2-6 Installing Memory CAUTION! Exercise extreme care when install- ing or removing DIMM modules to prevent any possible damage. The MEC must be populated in the manner described in Step 2 below. ! 1. Memory support: The P3TDLR supports 128/256/512 MB and 1 GB registered ECC SDRAM DIMMs. PC133 and PC100 memory are both supported at their respective speeds. However, the memory bus is synchronized to the front side bus speed meaning you can not use PC100 with a 133 MHz FSB. Using PC133 with a 100 MHz FSB will result in 100 MHz memory operation. 2. Memory Slots: The P3TDLR has four DIMM slots. There is no need to install the DIMM modules in pairs.
The P3TDLR is not sensitive to the installed position of the memory DIMMs in the DIMM slots. 3. Installing memory modules: Insert each DIMM module parallel to its slot's guide rails. Pay attention to the orientation of the two notches along the bottom of the module to prevent inserting a DIMM module incorrectly. Gently press down on the DIMM module until it snaps into place in the slot (see Figure 5-4). 4. Memory Position: The capacity of the memory modules can be mixed; however, the memory speeds should all be the same for best results. Figure 2-4. Side View of DIMM Installation into Slot Notch Notch Release Tab Release Tab Note: Notch should align with the receptive point To Install:
Insert module vertically and press down until it snaps into place. Pay attention to the bottom notches. To Remove: Use your thumbs to gently push each release tab outward to free the DIMM from the slot. 2-7 DIMM
