Server Memory Kit

This RIMLANCE kit provides 32GB of DDR4 server memory in a matched pair of 16GB Registered RDIMMs. It operates at 2133MHz with CL15 latency and includes ECC for data integrity in critical workloads.

Compatibility Constraints

These modules suit DDR4 servers and workstations that accept Registered ECC memory with a 2Rx4 organisation. They will not work in systems that require unbuffered UDIMMs, non-ECC memory or a different DDR generation.

Installation Notes

The 288-pin DIMMs install in the standard DDR4 server slots at 1.2V. The main risk is purchasing Registered ECC RDIMMs for a platform that only supports unbuffered or non-ECC memory, which prevents the system from booting.

Questions about this item

Will this 288-pin DDR4 RDIMM fit a standard desktop motherboard that uses unbuffered memory?

No — the modules are registered ECC RDIMMs, so they require a server or workstation platform that supports registered DDR4 memory.

If I keep my existing DDR4 2133 CL15 RDIMMs, can I add this 2Rx4 kit alongside them?

Yes, provided your system accepts 2Rx4 registered modules at 1.2 V and you populate slots according to the motherboard's population rules.

How can I confirm the kit is running at the rated 2133 MT/s with CL15 after installation?

Check the memory speed and timings in the BIOS/UEFI or with a tool such as CPU-Z; they should show DDR4-2133 and CAS latency 15.
