Installing Memory
Overview
The P3000(D)BX2 contains two (2) 168-pin DIMM (Dual In-Line Memory Module)
sockets for memory (
Figure 18 ). This provides support for up to 512 MB of on-board
memory using PC100 DIMM's, or higher as technology becomes available.
Memory Banks
SIMM’s (Single In-Line Memory Modules) typically require two (2) sockets filled with
identical modules in order to compose a bank. DIMM’s require only one socket.
Any of the DIMM sockets can be filled in any order with modules of any acceptable
size. For example, a 16 MB DIMM can be installed in Bank 0, while a 32 MB DIMM
can be installed in Bank 1.
DIMM Types Three (3) DIMM memory sizes (64, 128, and 256 MB) are supported. DIMM's of these
sizes can be installed in banks 0 and 1 in any combination in any order.
Memory size is detected by the system BIOS. Memory timing requires PC100 SDRAM
modules.

Installation
The procedure for installing a DIMM ( Figure 19 ) is outlined in the following table.

Removal
The procedure for removing a DIMM is outlined in the following table.
The system can operate without Bank 0 (DIMM 1) filled. However,
Crisis Recovery mode requires Bank 0 to be populated. For more information
on Crisis Recovery mode, see
