Exact-fit server kit

This 576GB kit contains twelve 48GB DDR5 4800 CL40 2Rx8 ECC registered RDIMMs at 1.10V. It is built for administrators who must populate every slot on a GIGABYTE MZ33-AR1 motherboard with the precise rank, voltage and timing the board expects.

Registered ECC requirement

The motherboard requires 288-pin registered ECC RDIMMs; unbuffered UDIMMs or SODIMMs will not work. Matching the board's population rules ensures all twelve modules are recognised at full capacity and run at the rated 4800 speed.

Kit convenience

The package delivers all twelve matched modules in a single shipment so the server can be fully populated in one maintenance window. No additional accessories or software are included.

Questions about this item

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

The modules will run at DDR5 4800 (PC5-38400) as long as the board's memory controller supports that speed with a fully populated 12-DIMM configuration; the registered design helps maintain stability at full capacity.

How does the 288-pin RDIMM interface affect what the memory controller can address?

The 288-pin registered DIMM form factor is required by the MZ33-AR1; the onboard register buffers address and command signals so the controller can drive all 12 slots at the rated 4800 MT/s without signal degradation.

What physical clearance does the 12-module kit need inside the server chassis?

Each module is a standard-height 288-pin RDIMM without a heat spreader, so they fit in the MZ33-AR1's DIMM slots with normal server airflow clearance; verify the chassis allows full-length DIMMs in all 12 positions.
