HPE MEM 32GB 2Rx4 DDR4-2666MHz RDIMM

The HPE 815100-B21 Memory Module provides 32 GB of DDR4 server-class memory with a 288-pin DIMM form factor and a 2666 MHz clock speed. This ECC module is intended for systems that require data integrity and steady performance, and is compatible with HPE server environments where qualified HPE SmartMemory is recommended.

Advantages

HPE DDR4 server memory is engineered for performance, power efficiency and reliability. The module supports error-correcting code (ECC) to protect data integrity, uses a 1.2 V operating voltage for reduced power consumption, and is built from selected DRAM components that undergo HPE qualification and testing to ensure signal integrity and stable operation in server workloads.

Suitable for

• Enterprise and SMB servers requiring 32 GB DDR4 memory
• Virtualization hosts and hypervisor platforms
• Database and business-critical applications that need ECC protection
• Systems using 288-pin DIMM slots compatible with DDR4 2666 MHz modules

Key specifications

How to use

Power down the server and follow the manufacturer's service manual for safe memory installation. Insert the 288-pin DIMM into a compatible DDR4 slot until the module latches securely. Populate memory channels according to the server's memory population rules to maximize performance and maintain ECC functionality. After installation, power on the system and verify that the BIOS/firmware recognizes the new 32 GB module and that ECC is enabled where applicable.

Recommendations

Install HPE-qualified memory modules in matching pairs or per the server vendor's channel population guidelines. Use HPE SmartMemory options where supported to ensure full compatibility and access to server-specific memory features; consult the server compatibility matrix and firmware updates before upgrading.
