  • Buffer typeRegistered
  • 512 GB total capacity from sixteen 32 GB modules
  • DDR5 6400 speed with CL52 latency for rated throughput
  • Registered ECC design corrects single-bit errors on the fly
  • 1 V operation matches the server memory controller spec
  • 288-pin RDIMM form factor fits the Supermicro H14DSG-OD motherboard

Purpose-built server memory kit

This 512 GB kit consists of sixteen 32 GB DDR5 RDIMMs rated at 6400 MT/s with CL52 latency and 1.10 V operation. Registered ECC circuitry and 2Rx8 organisation let the memory controller address every slot at full capacity while correcting single-bit errors on the fly.

Suited for fully populated Supermicro H14DSG-OD

Administrators who need the exact rank, voltage and timing the board expects will see immediate recognition at rated speed. Systems that require unbuffered UDIMMs, SODIMMs, lower densities or different DDR generations cannot use these modules.

KIT delivers sixteen matched RDIMMs

The package supplies all sixteen 288-pin modules in a single verified kit, removing the guesswork of mixing batches. No heat spreaders, software utilities or additional accessories are included beyond the memory itself.

Questions about this item

What motherboard must I already have for this 512GB DDR5 6400 ECC RDIMM kit to be recognized at full capacity?

The kit is validated for the Supermicro H14DSG-OD motherboard; its memory controller expects the exact 2Rx8 registered ECC profile at 1.1V and CL52.

If I keep older DDR5 RDIMMs in the same server, will this 16-module kit run at its rated 6400 speed?

Mixing ranks, voltages or timings forces the memory controller to down-clock all channels; the board manual shows the supported population order for full-speed operation.

How can I confirm the 512GB kit is operating at DDR5 6400 with ECC active after installation?

Check the BIOS memory-info screen or run a tool such as dmidecode; it should report 6400 MT/s, CL52, 1.1V, registered ECC and all 16 modules present.
