64GB DDR4-3200 ECC RDIMM for HP - R4S27A

Upgrade your HP server's memory with a high-performance 64GB DDR4-3200 ECC RDIMM designed for reliability, efficiency, and sustained workload performance. This ECC Registered memory module delivers the speed and stability essential for data-intensive enterprise applications, virtualization, databases, and mission-critical workloads. DDR4 technology brings notable improvements in bandwidth, power management, and thermal efficiency over previous generations, helping servers handle larger datasets and more concurrent tasks with less latency. ECC (Error-Correcting Code) protection helps detect and correct single-bit errors on the fly, reducing the risk of data corruption and system crashes. For HP environments, this 64GB module is crafted to integrate seamlessly with HP ProLiant and related servers that support DDR4 ECC RDIMM, enabling robust memory expansion without sacrificing reliability. Whether you’re expanding memory in a bi-modal data center, deploying virtualization, or scaling memory-intensive applications, this module is engineered to deliver consistent performance, long-term resilience, and straightforward installation.

• Enhanced performance and efficiency: DDR4-3200 delivers higher bandwidth and improved data transfer rates compared with older DDR generations, translating to faster application load times, quicker data processing, and smoother multi-tasking for HP servers. The 64GB capacity provides ample room for large databases, in-memory analytics, and dense virtualized environments, while enabling improved CPU utilization and reduced swap activity during peak workloads.
• ECC protection for data integrity: Built-in Error-Correcting Code detects and corrects single-bit errors automatically, helping prevent silent data corruption and system instability. This is critical for enterprise workloads, financial transactions, and server-based services where downtime and errors can have significant operational impact. ECC RDIMM memory is specifically designed for servers, delivering reliability alongside performance.
• HP-optimized compatibility: This module is designed to integrate with HP server platforms that support DDR4-3200 ECC RDIMM modules. It aligns with HP’s memory population rules, server BIOS expectations, and thermal/power envelopes to deliver stable operation in demanding workloads while maintaining compatibility with HP firmware and support ecosystems.
• Stability under load and scalable performance: DDR4 memory scales efficiently across channels and DIMMs, enabling better memory bandwidth utilization in multi-channel configurations. In enterprise scenarios, multiple modules (3DPC and beyond) can benefit from improved throughput and reduced latency, helping databases, virtualization hosts, and OLTP workloads respond faster under load.
• Power management and thermal efficiency: DDR4 memory is engineered to operate with lower voltages and improved signaling, contributing to lower overall server power consumption and thermal output. This translates to cooler operation, quieter data centers, and potential energy savings in large-scale deployments, all while preserving peak performance for HP systems.

how to install 64GB DDR4-3200 ECC RDIMM for HP - R4S27A

• Power down the HP server completely and unplug it from the power source. Ground yourself to prevent static discharge before handling memory modules.
• Open the server chassis and locate the memory risers or DIMM slots. Identify an available DDR4 ECC RDIMM slot that is compatible with HP memory population guidelines.
• Hold the RDIMM by the edges and align the module’s notch with the slot key. Insert the module at a slight angle and then press firmly until the retention clips snap into place, ensuring the module is seated evenly and securely.
• If you are upgrading a server with existing memory, consult the HP memory population guide to determine the optimal slot configuration and population order. In many cases, maintaining balanced channel population yields the best performance.
• Reassemble the server, reconnect power, and boot. Enter the BIOS/UEFI to verify that the system recognizes the 64GB RDIMM. Run a full memory diagnostic or stability test to confirm proper operation and stability under your typical workloads.

Frequently asked questions

• Q: Is this memory compatible with HP servers? A: Yes. This 64GB DDR4-3200 ECC RDIMM is designed for HP servers that support DDR4 ECC RDIMM modules. Always cross-check with HP’s official memory compatibility list for your exact server model and BIOS version to ensure full compatibility.
• Q: What speed does this memory run at? A: This module operates at 3200 MT/s (DDR4-3200). If the server’s configuration or BIOS settings limit the speed, the memory may run at a lower supported frequency while maintaining data integrity and stability.
• Q: Does this memory support ECC? A: Yes. ECC (Error-Correcting Code) memory detects and corrects single-bit errors, helping prevent data corruption and unexpected downtime in mission-critical workloads.
• Q: How much memory do I get? A: The module provides 64GB of total capacity. Verify your server’s maximum supported memory per DIMM and total system memory to plan the appropriate memory layout for your workload.
• Q: What about warranty and support? A: Warranty terms vary by retailer and region. Typical server memory modules come with a limited warranty and support options. Check the seller’s warranty policy and HP compatibility assurances before purchase.
