Exact-match DDR5 kit for GIGABYTE MZ33-CP1

This 512 GB kit delivers eight 64 GB DDR5 RDIMMs tuned for the GIGABYTE MZ33-CP1 motherboard. Registered ECC modules operate at 1.1 V with CL52 timing so the board recognises full capacity at rated speed. The 2Rx4 organisation and 288-pin form factor match the platform's memory-population rules precisely.

Registered ECC with 2Rx4 rank

Registered buffering offloads the memory controller while ECC corrects single-bit errors on the fly, preventing silent data corruption during sustained workloads. The 2Rx4 dual-rank layout allows all eight slots to run fully populated at DDR5-6400 without signal degradation. Samsung, Micron or Hynix die provide enterprise-grade stability for production servers.

Eight-slot population frees expansion space

Populating every DIMM slot with 64 GB modules reaches the board's maximum supported capacity in a single kit, leaving no empty sockets for future upgrades. No heat spreaders are fitted, so clearance for tall CPU coolers or dense chassis airflow is preserved. Verify the motherboard manual for approved population order before installation.

Questions about this item

What does the DDR5 6400 speed rating deliver once the modules are installed in a GIGABYTE MZ33-CP1?

The kit runs at 6400 MT/s with CL52 latency at 1.1 V, providing the exact data rate and timing the motherboard's memory controller expects for full-capacity operation across all populated slots.

How does the DDR5 RDIMM interface and ECC registration affect practical performance limits?

Registered buffering reduces electrical load on the controller so all eight slots can run at the rated 6400 MT/s, while on-die ECC corrects single-bit errors in real time to prevent silent data corruption.

What physical clearance and slot requirements must the chassis and motherboard meet for these 288-pin RDIMMs?

Each module uses the standard 288-pin DDR5 RDIMM form factor without a heat spreader, so they fit any motherboard slot wired for registered DDR5 provided the chassis allows full-height DIMM insertion.
