Installing and Removing 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 19 for the location of the standby power indicator LED location). Failure to
do so could damage the memory and the board.
The 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
board will not boot.
Incorrect insertion of a RIMM module or a CRIMM module in a RIMM connector can damage the
D850MD and D850MV boards.

Installing Memory

The 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 13. 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
(PC600 or 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 11).
