Server-grade DDR5 for 288-pin DIMM slots

This 32 GB Crucial module runs at DDR5 4800 with CL40 latency and 1.10 V. It carries ECC and registered buffering for error-corrected stability in multi-socket servers and workstations. The dual-rank 2Rx8 organisation helps maximise capacity per channel. No heat spreader is fitted.

Fits registered DDR5 platforms needing ECC

The 288-pin DIMM plugs into server motherboards that support registered DDR5 memory. Registered signalling reduces electrical load on the memory controller, allowing larger populations per channel. ECC corrects single-bit errors to protect data integrity in always-on workloads.

Replaces slower or smaller registered DDR5

Upgrading from lower-speed DDR5 or smaller-capacity registered modules adds bandwidth and density for virtualisation, databases and compute clusters. The jump is worth it when workloads are memory-bound and the platform supports DDR5 4800 registered operation. Not for consumer desktops or unbuffered memory slots.

Questions about this item

Does the 4800 MT/s DDR5 module hit a thermal limit first under sustained server workloads?

The module has no heat spreader and runs at 1.10 V, so sustained heavy loads will be limited by the server chassis airflow rather than an on-board thermal solution.

What is the power draw and noise impact when this 32 GB DIMM runs all day in a 288-pin slot?

At 1.10 V the module draws minimal power and produces no noise of its own; any audible change comes from the system fans responding to overall chassis temperature.

Must the motherboard already support DDR5-4800 ECC Registered 2Rx8 memory for this stick to work?

Yes, the board must accept DDR5 ECC Registered dual-rank modules at 4800 MT/s with a 288-pin DIMM interface.
