Gateway ALR 9200 Memory, To Remove the Memory Module, Removing the Memory Module

Installing Hardware

The server includes expandability features that allow you to add several types of hardware to the interior of the system. All of the procedures given in this section use the ESD precautions identified in “Static Electricity Precautions” on page 2. All of the procedures in this section refer to Chapter 2, “Installing Components”.

Memory

Main memory resides on an add-in board, called a memory module. The memory module contains slots for 16 DIMMs, each of which must be at least 32 MB, and is attached to the system board through a 242-pin connector. Memory amounts from 128 MB to 4 GB of DRAM are supported, with a 64/72-bit four-way-interleaved pathway to main memory. The 16 slots are divided into four banks of four slots each, labeled A through D. These banks support 4:1 interleaving. The memory controller supports EDO DIMMs only. The ECC used for the memory module is capable of correcting single-bit errors (SBEs) and detecting 100 percent of double-bit errors over one code word. Nibble error detection is also provided.

Removing the Memory Module

The memory module must be removed before you can change the memory configuration. See “Memory” on page 23 for memory size and requirements.

To Remove the Memory Module

1.Observe the safety and ESD precautions in “Static Electricity Precautions” on page 2.

2.Remove the access cover (see “Opening the System” on page 3).

3.Remove the foam cover over the electronics bay.
