Exact-Match 48 GB DDR5-4800 RDIMM

This 48 GB DDR5-4800 module is built to the precise 2Rx8 registered ECC specification that the GIGABYTE MZ33-CP1 motherboard expects. It installs as a single 288-pin RDIMM so the memory controller recognises the full capacity at rated speed without manual tuning.

1.1 V operation and registered buffering

Running at 1.10 V, the module keeps power draw low while the registered architecture buffers address and command signals. This reduces electrical load on the memory controller, allowing every slot to stay populated at full speed with minimal thermal impact.

ECC protection and population rules

On-die ECC corrects single-bit errors in real time, preventing silent data corruption that can crash production workloads. The board's manual defines the approved DIMM population order; following that sequence ensures the registered modules initialise correctly in every slot.

Questions about this item

How do I install this 288-pin RDIMM in the GIGABYTE MZ33-CP1, and which slot order do people get wrong?

Power down, open the chassis, align the 288-pin key with the DDR5 RDIMM slot, and press firmly until both clips lock. Follow the motherboard manual's population sequence — typically fill channel A first — because skipping the prescribed order prevents the 48 GB module from being recognised at full 4800 MT/s speed.

What maintenance or replacement will this 48 GB DDR5 ECC RDIMM need later?

No routine maintenance is required; the module has no heat spreader or moving parts. ECC corrects single-bit errors on the fly, but if uncorrectable errors appear in system logs the DIMM must be replaced — lifetime replacement coverage applies.

What limit appears first when this CL40 1.10 V registered DIMM runs sustained workloads?

The registered buffer and ECC logic add latency, so the CAS-40 timing at 4800 MT/s becomes the throughput ceiling before thermal or voltage limits are reached.
