  • 64 GB total capacity in a 4 x 16 GB kit for full server density
  • DDR5 4800 speed with CL40 latency matches the board's rated timing
  • Registered ECC RDIMM architecture offloads the controller and corrects single-bit errors
  • 1 V operation at 1Rx8 rank fits the motherboard's voltage and population rules
  • 288-pin DDR5 form factor verified for Supermicro H14DST-FL compatibility

Exact-Match Server Upgrade

This 64GB kit contains four 16GB DDR5 RDIMM modules rated at 4800MHz PC5-38400 with CL40 timing and 1.1V operation. The 288-pin registered ECC design matches the Supermicro H14DST-FL motherboard requirements for full-capacity recognition and rated-speed operation.

Enterprise Stability Focus

Suits administrators populating all slots on a Supermicro H14DST-FL platform where registered ECC memory is mandated for error correction and controller offload. Not suited for desktop boards that accept only unbuffered UDIMMs or systems requiring heat spreaders on every module.

Verified Fitment Kit

The four-module pack delivers the precise rank, voltage and timing configuration the board's memory controller expects for immediate compatibility. No extra software, cables or cooling accessories are included in the package.

Questions about this item

My Supermicro H14DST-FL board needs DDR5 RDIMMs — does this kit match the 288-pin registered form factor it requires?

Yes. The kit supplies four 288-pin DDR5 RDIMMs at 1.1 V, CL40, 4800 MT/s, exactly matching the board's registered memory slots.

Can I add these four 1Rx8 modules to existing DDR5 RDIMMs already installed in the server?

Only if the existing modules are also DDR5 4800 registered ECC 1Rx8 at 1.1 V; mixing ranks, speeds or voltages will prevent the system from running at full capacity.

After seating all four modules, how do I confirm the server sees the full 64 GB at DDR5-4800 with ECC active?

Enter the BIOS or use a hardware-inventory tool — it should report 64 GB total, 4800 MT/s speed, registered ECC enabled and the correct 1Rx8 rank per DIMM.
