Exact-match DDR5-6400 ECC RDIMM kit

This 64 GB kit contains two 32 GB DDR5-6400 registered ECC modules built to the 288-pin RDIMM form factor. It is validated for the GIGABYTE MZ33-CP1 motherboard and uses 2Rx8 Samsung Micron or Hynix chips running at 1.1 V with CL52 latency.

Registered DDR5 population limits

Registered architecture buffers the command bus so every slot can be populated without signal degradation, but the motherboard still enforces a maximum total capacity and a specific slot-filling order. Exceeding the board's approved DIMM count or ignoring the population sequence will prevent the system from posting at the rated 6400 MT/s speed.

Upgrade from non-ECC or lower-speed DDR5

Replacing unbuffered non-ECC DIMMs or slower registered modules eliminates single-bit error risk and restores full bandwidth when all channels are filled. The jump is worthwhile when the workload demands continuous uptime and the platform's qualified-vendor list includes this exact part number.

Questions about this item

Should I choose the 2×32 GB kit or a different capacity for the GIGABYTE MZ33-CP1?

The kit provides 64 GB total as two 32 GB modules, matching the board's DDR5-6400 RDIMM slot population rules; consult the motherboard manual for approved DIMM order and maximum supported capacity before buying.

What does the DDR5-6400 rating mean once the modules are installed in the server?

The memory controller will run the RDIMMs at 6400 MT/s with CL52 latency at 1.1 V, delivering the rated PC5-51200 bandwidth when all slots are populated per the board's configuration guide.

How does the 288-pin RDIMM interface and registered ECC design affect real-world operation?

The registered buffer reduces electrical load on the controller so every slot runs at full speed, while ECC corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots.
