  • 1TB total capacity from twelve 96GB modules for dense server workloads
  • DDR5 4800 speed with CL40 latency matches the board's rated memory controller limits
  • Registered ECC RDIMM design offloads the controller and corrects single-bit errors automatically
  • 2Rx4 dual-rank organisation enables full-population stability across all twelve slots
  • 10V operating voltage aligns with the Supermicro H14DST-FL memory specification

Exact-match DDR5-4800 kit for Supermicro H14DST-FL

This 1.1TB kit delivers twelve 96GB DDR5 RDIMMs built to the memory controller's exact rank, voltage and timing requirements. It targets administrators who need full-capacity population on the H14DST-FL without guesswork. Buyers who need UDIMM, SODIMM or non-ECC modules cannot use this kit.

1.1TB registered ECC capacity with CL40 timing

Twelve dual-rank 2Rx4 modules provide 1.1TB at DDR5-4800 (PC5-38400) running at 1.10V with CL40 latency. Registered architecture offloads the controller so every slot runs fully populated at rated speed while ECC corrects single-bit errors on the fly. Workloads exceeding 1.1TB or requiring lower latency than CL40 will need a different configuration.

288-pin RDIMM form factor with major OEM chips

Modules use Samsung, Micron or Hynix components in a 288-pin registered DIMM package without heat spreaders. The form factor matches the H14DST-FL's slot keying and population rules exactly. Systems that require UDIMM, SODIMM or unbuffered memory cannot accept these modules.

Questions about this item

Will the 12 DDR5 4800 RDIMM modules populate every slot on my Supermicro H14DST-FL without reducing the rated speed?

The kit is verified for the H14DST-FL motherboard and uses the exact 2Rx4 registered ECC layout the board expects, so all 12 slots can run at the full DDR5 4800 speed when populated per the manual's population order.

How can I confirm the 1.1 TB kit is running at CL40 and 1.10 V after installation?

Enter the BIOS or use a hardware-monitoring tool such as IPMI to verify the memory frequency shows 4800 MT/s, the CAS latency reads 40 and the DIMM voltage reports 1.10 V.

Does the 12-module box include heat spreaders or any cables I would need to add?

The package contains only the 12 bare 288-pin RDIMM modules; no heat spreaders, cables or additional accessories are included.
