Installing Memory
CAUTIONS
Before installing or removing RIMM modules, make sure that AC power has been removed by
unplugging the power cord from the computer. The standby power indicator LED should not be lit
(see Figure 3 on page 18 for the location of the standby power indicator LED location). Failure to
do so could damage the memory and the desktop board.
The desktop board supports combinations of no more than 32 RDRAM components per RDRAM
channel. If the total number of RDRAM components installed in all RIMM sockets exceeds 64, the
computer will not boot.
A Continuity RIMM (CRIMM) module must be installed in any unused memory connector or the
desktop board will not boot.
Incorrect insertion of a RIMM module or a CRIMM module in a RIMM connector can damage the
Desktop Boards D850EMD2 and D850EMV2.
The desktop board has four memory module sockets arranged as bank 0 and bank 1. The pair of
sockets closest to the processor is for bank 0, as shown in Figure 11. The memory module
requirements are listed in the Main Memory section on page 12.
When adding memory:
•
Install a pair of RIMMs in the sockets in bank 0 first. The RIMMs must be the same speed
(PC800), size (64 MB, 128 MB, 256 MB, or 512 MB), and density (single- or
double-sided).
•
If the desired memory configuration has been achieved in bank 0, install CRIMMs in the
sockets in bank 1 (see Figure 9).
