Note: Check the Supermicro web site for recommended memory modules:

CAUTION
Exercise extreme care when installing or removing DIMM
modules to prevent any possible damage. The MEC must be
populated in the manner described in Step 2 below.
Memory Support: The P4QH8/P4QH6 supports 128MB/256MB/512MB/
1GB and 2GB registered ECC DDR-266/200 SDRAM DIMM memory
modules*. Non-ECC or unbuffered SDRAM memory is not supported.
1. Removing the MEC (Memory Expansion Card):
You should remove the MEC whenever installing or removing DIMMs. The
MEC is attached to a retention plate with four screws. Do not remove
these. Instead, remove only the two screws that secure the MEC
retention plate to the chassis. After removing the board, place it on an
antistatic bag before inserting the DIMMs.
2. Populating the MEC:
Important: Because memory is accessed by a four-way interleaving
scheme, you must install modules four at a time and in the order shown
in Figure 2-2 and described here: Always install DIMMs from the bottom
of the MEC card up and in groups of four. If four DIMMs are to be
installed, you must populate the four DIMM slots along the bottom of the
MEC (see Figure 2-2). If eight are to be installed, you must populate the
eight bottom DIMM slots, and so on. It is recommended that all installed
DIMMs be the same brand, type, size and speed.
3. Inserting DIMMs:
Insert each DIMM module vertically into its slot. Pay attention to the notch
along the bottom of the module to prevent inserting it incorrectly. Gently
press down on the DIMM module until it snaps into place in the slot (see
Figure 2-3). If you use too much pressure when inserting the DIMMs you
may bend and damage the MEC.
*Note: TheP4QH8/P4QH6 has been designed to support 2GB DIMM
modules in each memory slot, but it has only been validated for 1GB
