5-6 Installing Memory
Note: Check the Supermicro web site for recommended memory modules:
http://www.supermicro.com/TECHSUPPORT/FAQs/Memory_vendors.htm
CAUTION
Exercise extreme care when installing or removing DIMM
modules to prevent any possible damage. Also note that the
memory is interleaved to improve performance (see step 1).
DIMM Installation (See Figure 2-2)
1. Insert either two or four DIMMs as required for the desired system
memory. Two-way interleaved memory requires that memory
modules be installed in pairs (first in the two slots of Bank0 and
then in both slots of Bank1, if needed).
2. Insert each DIMM module vertically into its slot. Pay attention to the
two notches along the bottom of the module to prevent inserting the
DIMM module incorrectly.
3. Gently press down on the DIMM module until it snaps into place in the
slot. Repeat for all modules (see step 1 above).
Support
The P3TDER only supports ECC registered SDRAM memory. PC133 and
PC100 memory are both supported at their respective speeds. However,
the memory bus is synchronized to the front side bus speed, so using
PC100 with a 133 MHz FSB or using PC133 with a 100 MHz FSB, will
result in 100 MHz memory speed operation in either case.

CAUTION! Exercise extreme care when install-
ing or removing DIMM modules to prevent any
possible damage.
