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.
About this memory module
SK Hynix 64GB DDR4-3200 ECC RDIMM, dual rank module HMAA8GR7AJR4N-XN to the PC4-3200AA specification, for the highest capacity DDR4 server builds. Tested and stocked in Doha, delivered across Qatar within a day.
SK Hynix's HMAA8GR7AJR4N-XN is a 64GB DDR4 ECC Registered DIMM at 3200MT/s, the largest registered DDR4 capacity that runs at full speed without moving to load reduced modules. It is a dual rank 2Rx4 module built on 16 gigabit chips, on the 288 pin RDIMM form factor to the PC4-3200AA specification, server grade, for Dell PowerEdge and HPE ProLiant systems.
Buyers in Qatar fit refurbished 64GB modules to 15th generation Dell and Gen10 Plus HPE servers for the largest memory footprints, 1TB across two sockets with sixteen modules, for in-memory databases, analytics and dense virtualisation. ServerDove keeps it in Doha stock.

Specification
Sixteen gigabit chips are what make a 64GB dual rank module possible; older 64GB parts needed load reduced buffering or four ranks and ran slower.

On third generation Xeon Scalable processors the module runs at 3200MT/s with one per channel; on second generation processors at 2933MT/s; on first generation at 2666MT/s. Sixteen modules give a dual socket 15th generation server 1TB with every channel populated, and 32 reach 2TB at a reduced speed.
Hynix's HMAA8 prefix identifies its 64GB 16 gigabit die parts, and the XN suffix marks the 3200MT/s grade. Dell and HPE both ship this class of module with their 15th generation servers, so it is a factory matched choice for extending a large set as well as for building one from empty. With one per channel a third generation processor runs eight of them at 3200MT/s for 512GB per socket.
Installation
Unplug the server before opening it. Fill one slot per channel across both processors in the board's marked order, then second slots only if capacity demands it. Press each module until both clips latch; 64GB modules are no heavier than smaller ones but seat with the same firm pressure. Check the BIOS total after boot; large sets take longer to train at first power on, which is normal.
