Product Identity

This SK hynix module is a 64GB DDR4 2133 ECC Load Reduced DIMM built for server platforms that require registered memory. The 4Rx4 organisation and Supermicro certification indicate validation for high-density configurations in qualified systems.

Suitability

It suits administrators upgrading or repairing Supermicro-qualified servers that specifically call for DDR4-2133 LRDIMMs at 1.20V. Buyers needing standard UDIMMs, RDIMMs, non-ECC modules, or different speed grades should look elsewhere because those variants are electrically and mechanically incompatible with this specification.

Deciding Specification

The single specification that determines fit is the 4Rx4 Load Reduced ECC design at DDR4-2133; only motherboards qualified for this exact module type will recognise and operate the memory correctly.

Highlights

  • 64 GB capacity for memory-intensive server workloads
  • DDR4 2133 speed delivers high data throughput
  • CL15 latency supports responsive operation
  • 2 V operation reduces power consumption
  • Supermicro certified for validated compatibility

FeaturesWelcome to my Store. Your perfect source for all kinds of Computer, Camera and Phone memory, DRAM, Flash Memory, Camera Cards, USB Drives, Micro SD SDHC SDXC Cards, Please add me to your list of favorite sellers and visit often. This listing contains ECC Memory Modules! These are for servers only and not normal desktops! ECC Registered DIMMs & ECC UDIMMS can not be mixed. If your system came with ECC UDIMMs then use of registered DIMMs will require the removal of all existing UDIMMs.

Questions about this item

Will this 288-pin DDR4 2133 LRDIMM run in my older server that only supports registered ECC DIMMs?

No — the module is Load Reduced (LRDIMM), not registered. It requires a platform that specifically supports LRDIMM topology and 4Rx4 organisation.

How can I verify the CL15 1.20 V timing is active after installation?

Enter the BIOS or use a tool such as CPU-Z and confirm the SPD shows DDR4-2133, CAS 15 and 1.20 V; the Supermicro certification means the module will train at those settings on validated boards.

Does the single 64 GB stick ship with any heat spreader or extra cables?

The unit has no heat spreader and includes only the memory module itself; no cables, brackets or additional accessories are supplied.
