Exact-match upgrade kit

This 64 GB kit contains four 16 GB DDR5 RDIMMs rated at 4800 MT/s with CL40 latency and 1.1 V operation. The modules are registered and ECC-enabled, matching the memory controller expectations of the GIGABYTE MZ33-AR1 motherboard. Each stick uses a 1Rx8 organisation and a 288-pin form factor. The kit is new and ready for installation.

Registered ECC architecture

The registered design buffers address and command signals so the memory controller can drive all four slots at full population without signal degradation. On-die ECC corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots in production workloads. This combination is required by the target platform for stable operation at rated speed.

Four-module population kit

The package delivers exactly four matched RDIMMs, allowing you to fill the board's supported channels in a single step. No heat spreaders are included, so airflow clearance follows the motherboard's standard DIMM spacing rules. Verify the manual for approved population order before installing to ensure the system recognises the full 64 GB capacity.

Questions about this item

What does the 4800 MT/s rating mean once the kit is installed in a GIGABYTE MZ33-AR1?

The memory controller will run all four 16 GB modules at DDR5-4800 (PC5-38400) with CL40 timing at 1.10 V, delivering the full 64 GB capacity at rated speed.

How does the registered ECC RDIMM interface affect operation on this motherboard?

The 288-pin registered design buffers address and command signals, letting the board run a fully populated 4-slot configuration at DDR5-4800 while ECC corrects single-bit errors on the fly.

What physical slot and clearance requirements does this 4-module kit have?

Each module is a standard 288-pin DDR5 RDIMM with no heat spreader, so it fits the four DIMM slots on the MZ33-AR1 following the board's population order.
