Verified DDR5-6400 RDIMM upgrade

This 64 GB DDR5 module runs at 6400 MT/s with CL52 latency and 1.10 V. It uses a 288-pin Registered ECC design built with major OEM chips. The kit is validated for the GIGABYTE MS04-CE0 motherboard so the memory controller recognises the exact rank, voltage and timing at full rated speed.

Registered ECC stability under load

The registered architecture buffers command and address signals, reducing electrical load on the memory controller when every slot is populated. ECC detects and corrects single-bit errors in real time, preventing silent data corruption during sustained compute or database workloads. The module maintains its rated 6400 MT/s throughput without downclocking when the system is fully populated.

Low-voltage operation and thermal profile

Operating at 1.10 V, the module draws less power per gigabyte than higher-voltage alternatives. No heat spreader is fitted, relying on chassis airflow for cooling in typical server environments. The registered design and ECC overhead add minimal latency while keeping power draw predictable during continuous operation.

Questions about this item

How much power does the 1.1 V DDR5 6400 module draw when the server runs continuously?

The module operates at the standard 1.1 V DDR5 voltage, so power draw scales with the 6400 MT/s data rate and 64 GB density; exact wattage depends on workload and the GIGABYTE MS04-CE0 memory controller.

What motherboard slot and firmware does the GIGABYTE MS04-CE0 need to accept this 288-pin RDIMM?

The board must provide a DDR5 288-pin RDIMM slot and a BIOS that supports 64 GB 2Rx4 registered ECC modules at 6400 MT/s; consult the MS04-CE0 manual for the approved population order.

Can I mix this CL52 2Rx4 registered ECC stick with older DDR5 UDIMMs I already own?

No — registered RDIMMs and unbuffered UDIMMs use different electrical signalling and cannot be installed together on the same platform.
