64 GB DDR5 ECC RDIMM Kit

This 64 GB kit provides two 32 GB DDR5 4800 registered DIMMs with ECC and a CL40 latency. It operates at 1.1 V and uses a 288-pin form factor designed for server platforms. The modules are built with major OEM chips and validated for Supermicro SYS-111C-NR, SYS-521C-NR and X13SEDW-F systems.

Who This Suits and Who Should Look Elsewhere

Administrators expanding memory in the listed Supermicro SuperServer models will find a tested, registered ECC solution that matches the platform requirements. Buyers needing non-ECC unbuffered DIMMs for consumer desktop boards cannot use this registered kit. Systems requiring a different speed grade, voltage or pin count should select memory specified for those parameters.

The Deciding Specification

Registered ECC DDR5 RDIMM format is the single attribute that determines compatibility. Only motherboards with DDR5 RDIMM slots supporting registered error-correcting modules at 4800 MT/s and 1.1 V can accept this kit.

Highlights

  • ECC protection prevents data corruption in critical workloads
  • Registered design stabilises signal integrity on dense server boards
  • 4800 MT/s throughput accelerates memory-bound applications
  • 1 V operation reduces power draw per module
  • Dual 32 GB sticks deliver 64 GB total capacity

Questions about this item

Does the 288-pin DDR5 RDIMM fit the memory slots on the SuperMicro SYS-111C-NR and SYS-521C-NR?

Yes, the 288-pin DDR5 RDIMM modules are designed for the DDR5 slots on the SuperMicro SYS-111C-NR, SYS-521C-NR and X13SEDW-F motherboards.

Do I need to populate specific DIMM slots first when installing the two 32GB modules?

Install each 32GB module into the primary channel slots indicated in the SuperMicro motherboard manual; the common mistake is using secondary slots before the primary ones are filled.

Will the Samsung, Micron or Hynix chips on these modules need any firmware updates later?

The memory chips do not require firmware updates; the only future action may be reseating the modules if the server is moved or vibrated heavily.
