Capacity and form factor

This 64 GB DDR4 LRDIMM module uses the 288-pin DIMM form factor and is built for server and workstation platforms that require registered, load-reduced memory. It delivers a single-module capacity of 64 GB to increase total system memory without occupying additional slots.

Upgrade path and fit

The module replaces the Hynix HMAA8GL7CPR4N-WM part and matches its DDR4 2933 (PC4-23400) speed, CL21 latency, 1.20 V voltage and 4Rx4 rank organisation. The jump is worthwhile when the motherboard and processor support load-reduced ECC DIMMs at this frequency and rank configuration.

Installation notes

Install by aligning the 288-pin edge connector with the DIMM slot and pressing until the retention clips engage; the load-reduced design reduces electrical load on the memory controller. Common issues include mixing LRDIMMs with standard RDIMMs or UDIMMs, populating unsupported rank counts per channel, or using a platform that does not enable ECC functionality.

Questions about this item

Will this 288-pin DDR4 LRDIMM fit my server's memory slots?

Yes, the module uses the standard 288-pin DDR4 DIMM form factor and 1.20V voltage, so it fits any server slot designed for DDR4 LRDIMMs.

Do I need to configure anything in the BIOS after installing this 4Rx4 ECC module?

Most servers detect the 64GB 4Rx4 LRDIMM at 2933MHz automatically; the common mistake is mixing LRDIMMs with standard RDIMMs in the same channel, which prevents boot.

When should I expect to replace this 64GB DDR4 2933 module?

The module has no moving parts and runs at standard 1.20V; replacement is only needed if a memory test reports uncorrectable ECC errors or the server's maximum capacity is reached.
