  • Samsung, Micron or Hynix major-OEM chips ensure enterprise-grade reliability

Exact-match DDR5-4800 ECC RDIMM for Supermicro

This 64GB DDR5 module runs at 4800MHz with CL40 timing and 1.10V voltage. It uses a 2Rx4 registered design with ECC for error correction. The 288-pin RDIMM form factor matches the Supermicro H14DST-F motherboard requirements exactly.

DDR5-4800 speed ceiling and registered buffer limits

The module operates at the DDR5-4800 standard with PC5-38400 bandwidth. Registered buffering allows full-capacity population across all supported slots by reducing electrical load on the memory controller. ECC corrects single-bit errors automatically. Maximum capacity and population rules are defined by the motherboard manual, not the module itself.

Straightforward 288-pin RDIMM installation

Installation follows standard 288-pin RDIMM alignment in the motherboard slots. The critical step is consulting the Supermicro H14DST-F manual for approved DIMM population order and supported capacity configurations. Incorrect slot placement or exceeding the board's validated capacity per channel will prevent boot or limit recognition. Not for systems requiring UDIMM, SODIMM, or non-ECC unbuffered memory.

Questions about this item

Should I pick the 64GB DDR5 4800 CL40 2Rx4 RDIMM or a different capacity for my Supermicro H14DST-F?

This module is a 64GB DDR5 4800 CL40 2Rx4 registered ECC RDIMM at 1.1V. Match the exact rank, voltage, and timing your server's memory controller expects so it is recognised at full capacity and runs at its rated speed.

What does the 4800 MT/s speed mean once the DIMM is installed in the H14DST-F?

The module runs at DDR5 4800 (PC5 38400) with CL40 latency at 1.1V. Registered architecture offloads the memory controller so every slot runs fully populated at full capacity while ECC corrects single-bit errors on the fly.

Does the 288-pin RDIMM interface limit how many modules I can install on this motherboard?

The H14DST-F requires 288-pin registered RDIMMs, not UDIMMs or SODIMMs. Consult your system or motherboard manual for supported capacities, approved DIMM population order, and installation steps before purchase.
