  • 384 GB total capacity from four 96 GB modules for dense server workloads
  • DDR5 4800 MHz speed with CL40 latency matches controller timing for rated performance
  • Registered ECC architecture offloads the memory controller and corrects single-bit errors on the fly
  • 1 V operating voltage reduces power draw per module at full load
  • 288-pin RDIMM form factor verified for GIGABYTE MZ33-AR1 motherboard compatibility

Capacity and Form Factor

This kit provides 384 GB of DDR5 registered ECC memory in a four-module configuration of 96 GB each. It uses the 288-pin RDIMM form factor required by compatible server motherboards and operates at 4800 MHz with a CL40 latency at 1.10 V.

Suitable Builds and Limitations

The kit is designed for servers that accept 2Rx4 registered DIMMs and can populate four slots at full capacity. Systems that require unbuffered UDIMMs, SODIMMs, or lower-density modules will not recognise this memory.

Deciding Specification

The registered ECC RDIMM design with 2Rx4 organisation determines whether the motherboard's memory controller can initialise all four modules at the rated speed and capacity.

Questions about this item

Should I choose the 384GB kit with four 96GB modules or a different capacity for my GIGABYTE MZ33-AR1?

This 384GB kit provides four 96GB DDR5 RDIMMs that match the MZ33-AR1's registered ECC requirements; verify your board's maximum supported capacity and population rules in the manual before deciding.

What does the 4800MHz speed mean once the modules are installed in the server?

The DDR5 4800 (PC5-38400) rating means the memory controller will run the kit at 4800 MT/s with CL40 latency at 1.1V, delivering the full rated throughput when all four slots are populated.

How does the 288-pin RDIMM interface and registered design affect what the system can do?

The 288-pin registered DDR5 RDIMM interface buffers address and command signals, allowing the MZ33-AR1 to run all four slots at 384GB total capacity while ECC corrects single-bit errors in real time.
