5-6 Installing Memory
1. Memory support
The P4SCi supports dual-channel, ECC or non-ECC unbuffered DDR-400/333/
266 SDRAM. Populating DIMM0A and DIMM1A and/or DIMM0B and DIMM1B
with the same size/same type of memory modules will result in dual channel
(two-way interleaved) operation, which is faster than single channel operation.
See the table on the following page for system configuration and the corre-
sponding memory speed support.
2. Installing memory modules
Insert each memory module vertically. 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 5-5).
!
CAUTION! Exercise extreme care when installing or remov-
ing DIMM modules to prevent any possible damage.
To Install: Insert module
vertically and press down
until it snaps into place.
Pay attention to the bottom
notch.

slot.
Figure 5-5. DIMM Installation
Note: The Intel E7210 chip supports unbuffered, non-ECC or ECC memory. If
ECC memory is installed, the ECC bits need to be initialized via BIOS before
beginning normal system operation. For system with 4 GB memory and a 2.4
GHz Pentium 4, initialization will take about 65 seconds before any video dis-
plays. Since ECC initialization takes time, the Watch Dog Timer select option
needs to be set to a time that will exceed the ECC initialization time.
