Capacity & Configuration

This RIMLANCE kit provides 64GB of DDR4 memory in a matched pair of 32GB modules. It is built for servers and workstations that require registered ECC RDIMMs to maintain data integrity under heavy workloads.

Installation Notes

The modules use the standard 288-pin DDR4 form factor and operate at 1.2V, so they seat in any compatible registered DIMM slot. The critical step is confirming that the platform supports DDR4 registered ECC memory; consumer desktop boards and laptops will not accept these modules.

Target Audience

This kit suits administrators expanding memory in DDR4-based servers or workstations that specifically require registered ECC RDIMMs. Buyers who need unbuffered ECC, non-ECC UDIMMs, or a different speed grade should look at other products.

Questions about this item

How can I confirm the 2666 MHz speed and CL19 latency are active after installing the 2Rx4 RDIMMs?

Enter the server BIOS or UEFI and check the memory information screen; it should show DDR4 2666 (PC4-21300) at CL19 with registered ECC mode enabled.

What exactly ships in the box and what must I source separately?

The package contains two 32 GB 288-pin DDR4 RDIMM modules for a total of 64 GB; no extra brackets, cables or software are included or required.

Should I choose the 2Rx4 32 GB sticks or look for a different rank configuration?

Select this 2Rx4 kit when your server's memory qualification list approves dual-rank x4 registered DIMMs at 1.2 V for maximum capacity per slot.
