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 below). To remove
your DIMM, simply pull the clips back, and pull up on the module.

Place the DIMMs in an antistatic bag as soon as you remove them to avoid
static damage.
The Thunder X uses a 64-bit data path from memory to CPU and can accom-
modate up to 1024MB of SDRAM (2GB of SDRAM has not been validated).
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 the Figure 2-5 on the
following page). All installed memory will be automatically detected, so there
is no need to set any jumpers.
