## Long description

HP 4GB DDR4-2133 ECC 288-pin DIMM is a single-module memory upgrade designed for compatible PCs and servers. This module uses DDR4 technology at 2133 MHz with CAS latency 15 and includes ECC support to detect and correct single-bit memory errors, improving data integrity in workstation and server environments. The module fits standard 288-pin DIMM slots and is intended for systems that support unbuffered ECC DDR4 memory.
Advantages
The module offers error-correcting code (ECC) functionality to reduce the risk of data corruption and enhance system stability under sustained workloads. Its DDR4-2133 specification provides a balance between performance and power efficiency compared with previous-generation memory. Compact single-module format allows straightforward upgrades or replacement in compatible systems without complex configuration changes.
Suitable for
Rack and tower servers requiring ECC memory for improved reliability
Workstations used for data analysis, virtualization, or database tasks
Memory upgrades or replacements in compatible HP and industry-standard systems
Environments where data integrity and uptime are priorities
Key specifications
Memory type: DDR4 SDRAM
Capacity: 4 GB
Clock speed: 2133 MHz
CAS latency: 15
ECC: error-correcting code support (single-bit error correction)
Form factor: 288-pin DIMM
Module configuration: single-rank (typical for 4 GB server DIMMs)
How to use
Power down the system and disconnect power before installing the memory module. Open the server or PC chassis to access the DIMM slots and consult the system manual for the correct slot population order and any platform-specific requirements. Align the module with the 288-pin DIMM slot notch and press evenly until the retaining clips engage. Reassemble the chassis, reconnect power, and power on the system. Verify that the platform firmware or operating system recognizes the new module and that ECC is enabled if supported by the system.
Usage recommendations
For reliable operation, install memory modules in matched capacity and specification pairs where the platform recommends dual-channel or multi-channel configurations. Use modules that are qualified for your specific server or workstation platform and ensure system firmware is up to date to enable any extended memory features provided by the platform.
