Server DDR5 module for registered ECC systems

This 16 GB Crucial DDR5-4800 DIMM is built for servers and workstations that require registered memory with error correction. It operates at 1.10 V and uses a single-rank 1Rx8 organisation. The module has no heat spreader.

Registered ECC with CL40 latency at 4800 MT/s

The key specification is the registered ECC design combined with a CL40 CAS latency at the DDR5-4800 data rate. This combination determines compatibility with platforms that mandate registered buffers and error-correcting code. Systems needing unbuffered or non-ECC memory cannot use this module.

Standard 288-pin DIMM installation

Installation follows the usual 288-pin DIMM procedure: align the notch, press firmly until the retention clips engage. Because the module lacks a heat spreader, clearance is rarely an issue. The main risk is mixing registered ECC with unbuffered or non-ECC DIMMs, which prevents the system from posting.

Questions about this item

What does the 4800 MT/s rating deliver in a live server?

The module runs at DDR5 4800 (PC5 38400) with CL40 latency, giving your CPUs the bandwidth to keep more threads fed without waiting on memory.

How does the registered ECC interface affect usable speed and data integrity?

Registered buffering adds one cycle of control stability, while on-die ECC corrects single-bit errors in real time, letting the 4800 MT/s bus run reliably under sustained load.

What physical slot and power does the 1Rx8 288-pin DIMM require?

It fits a standard DDR5 288-pin RDIMM socket and operates at 1.10 V, with no heat spreader to clear oversized CPU coolers.
