HPE - Memory 64GB PC4-3200AA-R 4Gx4 - 64 GB - 64 GB - DDR4 - 3.200 MHz ECC DIMM R-DIMM CL22

The HPE DDR4 64GB 3200MHz ECC memory module delivers 64 GB of DDR4 server-grade memory with ECC support and a 3200 MHz clock rate. This 288-pin DIMM is designed for HP Enterprise server platforms and compatible systems that require high-capacity, error-correcting memory to maintain data integrity under load. The module supports registered/buffered or load‑reduced configurations as specified by system requirements and is intended for use in multi‑processor server environments where stability and predictable performance are important.

Advantages

This memory module combines high capacity and a fast 3200 MHz clock speed with ECC technology to detect and correct single-bit memory errors, reducing the risk of data corruption. The 288-pin DIMM form factor ensures compatibility with standard DDR4 server sockets. Using server-qualified components from HP Enterprise helps maintain firmware and hardware compatibility, supporting consistent performance and uptime in virtualized, database, and compute-heavy workloads.

Suitable for

• Enterprise servers and rack-mounted systems
• Virtualization hosts and hyperconverged infrastructure
• Database servers and in-memory databases
• High-performance computing and analytics
• Systems requiring high memory capacity and error correction

Key specifications

• Capacity: 64 GB
• Memory type: DDR4
• Clock speed: 3200 MHz
• Form factor: 288-pin DIMM
• Error correction: ECC (error-correcting code)

How to use

Install the module into a compatible server motherboard DDR4 DIMM slot following the server manufacturer's installation procedure. Power down the system and disconnect power before fitting the DIMM, align the notch with the slot keyed position, and press evenly until the retention clips engage. After installation, power on the server and verify that the BIOS/UEFI detects the new memory and that ECC is enabled if required by the platform. Populate memory channels according to the server's population rules to ensure optimal performance.

Recommendations

For reliable operation, use this module in matched pairs or in configurations recommended by the server vendor, and check firmware and BIOS updates for memory compatibility. Avoid mixing different speeds or types of memory in the same channel to prevent performance degradation. Maintain proper cooling and airflow in the server chassis to support sustained operation at 3200 MHz.
