HP Enterprise P07646-H21 32GB DDR4-3200 ECC Registered DIMM

Server memory failures and capacity bottlenecks can bring critical workloads to a halt. The HP Enterprise P07646-H21 memory module addresses this by delivering 32 GB of reliable DDR4 capacity with error correction, engineered for HPE ProLiant servers and workstations that demand uninterrupted operation.

Who is it for

System administrators and IT professionals managing HPE ProLiant servers or workstations who need to expand memory capacity while maintaining data integrity and performance under continuous load.

Main features

• 32 GB DDR4 module operating at 3200 MHz for high-speed data access
• ECC (Error-Correcting Code) detects and corrects single-bit memory errors, reducing downtime
• Registered DIMM (RDIMM) architecture improves signal integrity and allows higher memory densities in servers
• Dual Rank (2Rx4) configuration balances capacity and performance for demanding applications
