Exact-Match Server Kit

This 32 GB kit contains two 16 GB DDR5 RDIMMs rated at 4800 MT/s with CL40 latency and 1.1 V operation. It is built for administrators upgrading a GIGABYTE MZ33-AR1 motherboard that requires registered ECC modules in a 288-pin form factor.

Registered ECC Architecture

Registered buffering reduces electrical load on the memory controller so every slot can be populated at full capacity. On-die ECC detects and corrects single-bit errors automatically, preventing silent data corruption that would otherwise cause unplanned service interruptions.

288-Pin RDIMM Installation

Align the module notch with the slot key, press evenly until the retention clips engage, and follow the motherboard manual for population order. The most common issue is mixing RDIMMs with unbuffered UDIMMs or using an unsupported slot sequence, which prevents the system from posting.

Questions about this item

Will the ECC registered RDIMM modules need replacement after a certain period of operation?

The kit carries a lifetime replacement warranty, so the modules are covered for as long as you own them.

What limits sustained throughput on the DDR5 4800 CL40 kit?

The CL40 CAS latency at 4800 MT/s sets the timing ceiling for continuous workloads.

How much heat and power do the 1.1 V modules generate under all-day load?

Operating at 1.10 V with no heat spreader keeps power draw low, though exact thermal output depends on chassis airflow.
