Capacity 768GB (12 x 64GB)

  • Massive 768 GB capacity from twelve 64 GB modules
  • ECC protection detects and corrects memory errors
  • Registered design reduces electrical load on the memory bus
  • DDR4 2933 speed delivers high bandwidth for server workloads
  • Low 1.2 V operation cuts power draw and heat

768GB DDR4 ECC RDIMM kit

This kit supplies 768GB of DDR4 2933 registered ECC memory in twelve 64GB modules. It is built for servers and workstations that require error correction and registered signalling for large-capacity configurations.

Upgrading from smaller RDIMM sets

The jump is worthwhile when your workload exceeds the capacity of a lower-density kit and the motherboard supports 64GB dual-rank modules at this speed. Systems already running DDR4 2933 RDIMM can add this kit to reach the maximum supported memory without changing voltage or form factor.

Verify motherboard qualification list

Confirm the board accepts 2Rx4 64GB RDIMM modules at DDR4 2933 and that all twelve slots can be populated simultaneously. Check the vendor’s qualified-vendor list for the exact part number MR23400-924K12 before ordering.

Questions about this item

Will these 288-pin DDR4 RDIMM modules fit my server motherboard's DIMM slots?

These are standard 288-pin DDR4 RDIMM modules; they fit any server motherboard that accepts 288-pin registered DDR4 DIMMs.

What is the correct order to populate the 12 modules across the CPU memory channels?

Follow the motherboard manual's channel population guide; typically you fill one DIMM per channel per CPU before adding a second rank to any channel.

Do the Samsung, Micron or Hynix chips on these 2Rx4 modules require any firmware updates or periodic reseating?

No firmware updates are needed for the DRAM chips; reseating is only necessary if the server reports correctable ECC errors after prolonged thermal cycling.
