Dell Server Memory Kit

This NEMIX RAM kit supplies 64GB of DDR4 3200 ECC registered memory in a matched pair of 32GB modules. It is built for Dell servers and workstations that require registered DIMMs with error-correcting code for data integrity.

Two-Module Matched Pair

The kit contains two identical 32GB RDIMMs tested together to ensure stable dual-channel operation at PC4-25600 speed. Using a validated pair removes the guesswork of mixing individual sticks and helps the system initialise cleanly at the rated 3200MHz frequency.

2Rx4 Registered ECC Configuration

Each module uses a 2Rx4 organisation with registered buffering and ECC, a combination that many Dell platforms mandate for capacities above 32GB per slot. Systems that require unbuffered UDIMMs or non-ECC memory will not accept these RDIMMs.

Questions about this item

Will the 2Rx4 ECC RDIMM modules need firmware updates or scheduled replacement?

No firmware updates are required for these DDR4 3200 ECC RDIMM modules. They are designed for continuous server operation and carry a lifetime replacement warranty from the manufacturer.

What limits sustained throughput on this 64 GB kit running at CL22?

The CAS latency of 22 cycles at 3200 MT/s sets the primary latency bound, while the registered buffer adds one cycle of command delay under heavy sustained loads.

How much heat and noise do the two 32 GB sticks produce in a Dell server running 24/7?

The modules operate at 1.2 V without heat spreaders, relying on chassis airflow; they generate minimal heat and produce no audible noise.
