  • 10 V operation matches the motherboard's memory-controller specification exactly
  • 288-pin RDIMM form factor fits the required slots without adapters or mismatches

Server-grade DDR5 kit

This 384 GB kit contains four 96 GB DDR5-4800 RDIMM modules built for the GIGABYTE MZ33-CP1 motherboard. Registered ECC design and CL40 timing at 1.10 V match the board's memory controller so the full capacity is recognised at rated speed.

DDR5 RDIMM constraints

The 288-pin registered form factor is required; UDIMM or SODIMM modules will not fit or function. Population rules in the motherboard manual dictate which slots must be filled first and the maximum supported capacity per channel.

384 GB capacity headroom

Four ranks per module allow the memory controller to address the full 384 GB when all slots are populated correctly. Workloads that exceed this total or need higher bandwidth than DDR5-4800 provides will require a platform with greater memory limits.

Questions about this item

Should I choose the 384GB kit or a smaller capacity for my GIGABYTE MZ33-CP1?

The 384GB kit provides four 96GB modules that fill every slot on the MZ33-CP1, letting the registered ECC design run at full DDR5 4800 speed with all ranks populated.

What does the DDR5 4800 CL40 rating mean once installed in the server?

The modules operate at 4800 MT/s with CAS latency 40, delivering PC5 38400 bandwidth while the registered buffer keeps signal integrity stable across all four DIMMs.

How does the 288-pin RDIMM interface affect compatibility and performance?

The 288-pin registered form factor matches the MZ33-CP1 memory slots exactly; the buffer offloads the controller so all four slots run at the rated 4800 speed without down-clocking.
