About This Product
Overview
SK Hynix 64GB DDR4 ECC Registered DIMM server memory is designed for business-class systems that require dependable capacity and stable operation. With a 3200MT/s memory speed and PC4-3200AA specification, this module is suited for server environments where consistent performance matters. The 288-pin RDIMM design and ECC registered architecture make it a practical choice for compatible Dell PowerEdge and HPE ProLiant platforms. As a 2Rx4 dual rank module, it offers a balanced configuration for server memory expansion while maintaining compatibility with systems that support DDR4 RDIMM modules. The listed model HMAA8GR7AJR4N-XN helps identify the exact module for procurement and replacement planning.
Performance & Scalability
This 64GB module provides a straightforward way to increase installed memory in supported servers, helping systems handle larger workloads, virtualization tasks, database activity, and general enterprise applications. DDR4 ECC Registered memory is commonly used in server builds because it is engineered for stability and error correction, which are important in always-on environments. The 3200MT/s speed supports responsive data handling, while the dual rank 2Rx4 layout can help deliver efficient memory access in compatible platforms. For IT teams managing upgrades or replacements, this module can be used to expand capacity without changing the overall memory technology already in place, making it a useful option for maintaining system consistency across supported server fleets.
Storage Flexibility
While this product is a memory module rather than a storage device, it plays an important role in how effectively a server handles storage-related workloads. Additional RAM can improve the performance of applications that rely on caching, indexing, file services, and data processing, helping systems respond more efficiently when working with local drives or shared storage environments. In servers that support Dell PowerEdge or HPE ProLiant memory configurations, adding a 64GB RDIMM can be a practical step when balancing compute resources with storage-intensive tasks. The server-grade design and ECC support make it suitable for environments where reliability is a priority alongside capacity expansion.
Why Choose This Product?
This SK Hynix module is a strong fit for buyers looking for a clearly identified, server-grade DDR4 memory option with the specifications needed for compatible enterprise systems. The combination of 64GB capacity, ECC registered design, 3200MT/s speed, and 288-pin RDIMM form factor makes it well suited for targeted upgrades and replacements. Because the module is listed with a specific model number and compatibility notes, it is easier to match to existing hardware requirements during maintenance or expansion projects. For organizations that want to extend the useful life of supported servers while keeping memory configurations aligned with platform requirements, this module offers a practical and straightforward solution.

Why Buy a Refurbished Products?
Refurbished enterprise servers offer enterprise-grade performance at a fraction of the new price.
Up to 70% Cost Savings
Refurbished R650xs units deliver identical hardware capability to new, at significantly lower upfront cost — freeing budget for CPUs, RAM, and storage.
Fully Tested & Verified
Every unit undergoes comprehensive hardware diagnostics before dispatch. POST tests, burn-in, memory checks, and power supply verification are standard.
Immediate Availability
Unlike new enterprise servers with lead times of weeks or months, refurbished stock is ready to ship within 24 hours of ordering.
Same Performance
The hardware inside the R650xs performs identically whether purchased new or refurbished. The 3rd Gen Xeon platform, PCIe Gen4, and iDRAC9 are unchanged.
