# Troubleshooting: Memory Components

Memory is internal storage areas in the server.

All memory is registered, low profile (1.125 to 1.2") 184 pin 2.5V JDEC standard form factor with gold contacts.

DIMM, or dual in-line memory module, is a small circuit board that holds memory chips. A DIMM has 64-bit path to the memory chips.

> CAUTION: Do not attempt to service the system except as explained in the documentation. Only trained service technicians should remove the system cover to access any of the internal components. Refer to the documentation for your server for complete safety information before attempting to service your system.

Visually Inspecting Your System

Improperly set controls and loose or improperly connected cables are common causes of problems with hardware components. When investigating a system problem, first check all the external switches, controls, and cable connections. If this does not resolve your problem, then visually inspect the system's interior hardware for problems such as a loose card, cable connector, or mounting screw. Refer to Visual System Inspection for instructions about how to verify that your hardware components are properly installed.

Troubleshooting the Memory Component

Following are possible causes of problems with the memory component:

- System Power problems.
- Check the configuration rules for DIMMs. Refer to the documentation for your server.
- Do not mix DIMM speeds or you may experience a performance impact.

Run the diagnostics tests for memory modules to locate and diagnose memory problems.
