Servicing DIMMs (CRU)

This section describes how to service memory modules (DIMMs).

The Oracle Exadata Database Server X8-8 supports a fixed base configuration of forty-eight 64 GB quad-rank (QR) Load-Reduced (LR) DIMMs. Optionally, customers can expand system memory by upgrading to ninety-six 64 GB DIMMs

The following topics and procedures provide information to assist you when replacing a DIMM or upgrading DIMMs:

• DIMM Physical Layout and Numbering

• DIMM Population Rules

• DIMM Population Scenarios

• DIMM Operating Speeds

• Inconsistencies Between DIMM Fault Indicators and the BIOS Isolation of Faulty DIMMs

• Identify and Remove a Faulty DIMM

• Install a DIMM

DIMMs are customer-replaceable units (CRUs). For more information about CRUs, see Illustrated Parts Breakdown and Customer-Replaceable Units. For component serviceability, locations, and designations, see Replaceable Components.

Caution:

These procedures require that you handle components that are sensitive to electrostatic discharge. This sensitivity can cause the components to fail. To avoid damage, ensure that you follow antistatic practices as described in Electrostatic Discharge and Static Prevention Measures.
