Memory Module Dell DDR4 32GB 2RX4 2400MHz

The Dell 32GB DDR4 memory module 2RX4 2400MHz (MPN: AA783422-RFB) is a single-rank (1x32GB) server/workstation DIMM designed to expand system memory capacity and improve multitasking performance. Operating at 2400MHz with a 2RX4 organization, this ECC-capable form factor is intended for environments where stable, sustained performance and compatibility with Dell platforms are important. The module supports memory-intensive workloads, accelerating data processing and reducing paging delays when upgrading from lower-capacity modules.

Advantages

This Dell DDR4 32GB module offers high capacity in a single DIMM, which simplifies upgrades and frees DIMM slots for future expansion. The 2400MHz speed provides a balance of throughput and latency suitable for servers and professional workstations. The 2RX4 configuration supports error-correcting features and compatibility with systems tuned for registered or buffered memory, delivering reliable operation under continuous load.

Suitable for

• Server memory upgrades in Dell PowerEdge and compatible systems
• Workstation configurations for CAD, virtual machines, and content creation
• Database caching and in-memory processing environments
• Virtualization hosts running multiple VMs

How to use

Power down the system and follow the server or workstation manufacturer’s service manual for safe installation procedures. Discharge static by using an anti-static wrist strap or touching a grounded metal surface. Open the chassis, locate the appropriate DIMM slot(s), and align the module notch with the socket key. Insert the DIMM firmly until the retention clips engage. Reassemble the chassis, power on the system, and verify memory recognition in BIOS/UEFI or the system management interface. If the platform supports memory configuration tools, confirm settings such as registered/loaded status and ECC operation.

Usage recommendations

For best compatibility and performance, install this Dell DDR4 32GB module in matched pairs or according to the server’s memory population guidelines. Confirm firmware and BIOS updates are applied on the host system prior to large memory upgrades. Use modules specified by Dell or validated by the hardware vendor to ensure full support for ECC, registration, and platform-specific memory features.
