HP Compatible 627808-B21: 16GB DDR3 ECC REG RAM Module

Upgrade your HP server or workstation with confidence using the HP Compatible 627808-B21 memory module. This 16GB DDR3 SDRAM module blends ECC protection with Registered (REG) technology to deliver dependable performance for data-intensive workloads, virtualization, and memory-heavy applications. Engineered to fit HP ProLiant servers and other HP-certified systems, it provides reliable memory bandwidth at 1333MHz to accelerate multitasking, large datasets, and demanding software suites. With 16GB per module, you get a substantial boost for memory-hungry tasks without the complexity of specialized configurations. ECC (Error-Correcting Code) helps prevent data corruption, while Registered buffering maintains signal integrity across multiple DIMMs, making this a robust, server-grade upgrade. The memory module is backed by a lifetime warranty, offering long-term protection for your IT investment and peace of mind as workloads scale. Whether expanding an existing HP setup or planning a scalable memory upgrade, this DDR3 RAM is a cost-effective, plug-and-play solution that delivers immediate performance gains with reliable stability.

• 16GB DDR3 SDRAM Registered ECC RDIMM, 240-pin module, 1333MHz (PC3-10600) speed — ideal for virtualization hosts, large databases, in-memory caching, and memory-hungry applications in HP servers. The generous capacity reduces paging, speeds up data access, and allows more virtual machines or demanding processes to run concurrently without bottlenecks.
• ECC and Registered (REG) memory for reliability — ECC detects and corrects common memory errors to prevent data corruption during long-running analytics, databases, or virtualization workloads. Registered buffering balances electrical load across many DIMMs, preserving signal integrity in multi-channel configurations and delivering consistent performance under peak demand.
• HP-compatible and tested — specifically designed and validated for HP ProLiant servers and other HP-certified systems. This minimizes compatibility risks and aligns with HP memory population guidelines, ensuring smoother upgrades and stable operation when installed with compatible modules.
• Lifetime warranty and quality assurance — backed by a lifetime warranty, with rigorous testing to meet enterprise reliability standards. This means faster replacements and dependable support if you encounter any manufacturing defects, helping to protect your upgrade investment over time.
• Easy upgrade with immediate impact — a straightforward, plug-and-play upgrade that typically requires no BIOS adjustments. Expect improved multitasking, faster application response, quicker boot times, and better overall system performance in daily operations and workload-heavy tasks after installation.

How to install HP Compatible 627808-B21 memory module

• Power down the system, unplug power cords, and ground yourself to prevent static discharge.
• Open the server or workstation memory access panel and locate the empty DDR3 DIMM slots compatible with RDIMM modules.
• Align the notch on the memory module with the slot key and insert at a slight angle (about 45 degrees). Push down firmly until the latches on both sides click into place.
• If installing multiple modules, follow HP’s population guidelines to place memory modules in the recommended channels for optimal multi-channel performance.
• Replace the access panel, reconnect power, and boot. Enter BIOS or UEFI to verify that the memory is detected and running at the advertised speed. If available, run a memory diagnostics test to confirm stability.

Frequently asked questions

• Q: What systems is this memory compatible with?
• A: This module is HP-compatible and designed for HP ProLiant servers and other HP-certified systems that support DDR3 RDIMM ECC REG memory at 16GB per module and 1333MHz speed. Always consult your server’s memory compatibility list and HP’s memory population guidelines before upgrading.
• Q: What is the speed and standard of this RAM?
• A: It operates at 1333MHz DDR3 (PC3-10600) with ECC and Registered buffering, provided in a 240-pin RDIMM form factor.
• Q: Should I mix memory brands or speeds?
• A: For best stability and performance, use DIMMs of the same speed, capacity, and ECC/REG features across installed modules. Mixing different speeds or unbuffered/non-ECC memory can limit performance or cause compatibility issues.
• Q: What warranty is included?
• A: The memory module comes with a lifetime warranty, offering coverage for manufacturing defects and providing replacements as needed during the module’s lifespan.
• Q: Will this upgrade improve gaming performance?
• A: This memory is engineered for server-grade reliability and multi-tasking workloads. While it can improve overall system responsiveness in many scenarios, gaming performance depends on the rest of the system configuration. For consumer gaming, dedicated gaming-focused RAM configurations may yield different results.
