IBM - 33L5039 - IBM 1GB PC2100 ECC DDR SDRAM RDIMM

IBM 33L5039 1GB PC2100 ECC DDR SDRAM RDIMM

The IBM 33L5039 is a 1GB PC2100 (DDR-266) ECC DDR SDRAM registered DIMM (RDIMM) designed for enterprise platforms that require buffered memory and error correction. It’s a practical choice for maintaining or expanding legacy server configurations where PC2100 RDIMMs are specified, supporting stable operation in 24/7 environments.

This module installs directly into compatible IBM platforms via the server’s SYSTEM BOARD DIMM slots and is commonly used in older IBM server generations that support DDR RDIMM memory. For complete lifecycle maintenance, it is often upgraded alongside a matching CPU when balancing memory capacity with processor performance in production workloads.

If you are standardising spares across an installed base, this module is frequently relevant in IBM server families and configurations found in data center and remote-site deployments. It can also support repairs and capacity planning for compatible RACK SERVER environments where consistent memory type and ECC operation are required.

Key Features

Key specifications and deployment-relevant characteristics for this memory module:

• 1GB capacity RDIMM to add basic memory headroom for legacy server workloads and OS requirements.
• PC2100 (DDR-266) speed grade to match platforms that require DDR-266 registered memory.
• ECC (Error-Correcting Code) support to help detect and correct memory errors for improved system stability.
• Registered (buffered) DIMM design to support enterprise-class memory signaling and higher stability under load.
• DDR SDRAM technology to maintain compatibility with systems built for first-generation DDR memory.
• Designed for IBM server memory channels to support consistent population rules and predictable operation.
• Suitable for maintenance spares to keep older, business-critical systems running without platform changes.
• Appropriate for mixed fleet lifecycle management to extend service life where PC2100 RDIMMs are still specified.

Refurbished Quality and Warranty

This is refurbished hardware, cleaned and tested by technicians before entering stock to help reduce the risk of hardware defects. Refurbished memory is a cost-effective way to extend the lifecycle of existing IT environments while also reducing electronic waste compared to replacing entire systems.

All products from Direct Hardware Supply include a one-year warranty from the date of purchase (batteries, tape drives and tape libraries include a three-month warranty). Extended warranty options are available on request, and we ship worldwide from Denmark for international B2B projects.
