To install your DIMMs, line your module up so that the pins fit into the slot. There is only one way that your DIMM can fit properly. Make sure that the short row of pins is lined up with the short gap in the DIMM slot. Figure 2-3 above shows how to sit the DIMM into its slot. To insert the DIMM, push down vertically on the module with even force, as shown in the photo. Do not shove one end in first; doing so will bend the DIMM pins.
To lock the DIMM into place, push the plastic clips on either end of the slot onto the notches in the ends of the DIMM (see Figure 2-4 on the next page). To remove your DIMM, simply pull the clips back, and pull up on the module. Place the DIMMs in an anti-static bag as soon as you remove them to avoid static damage.
The Trinity 100AT uses a 64-bit data path from memory to CPU and can accommodate up to 384MB of SDRAM. The 168-pin DIMMs (Dual In-line Memory Modules) must be of the 3.3V, unbuffered variety. The position of the notch in the SDRAM key position will tell you whether or not a DIMM is unbuffered (see Figure 2-5 below). All installed memory will be automatically detected, so there is no need to set any jumpers.
