Exact-fit DDR5 kit for Supermicro H14DST-FL

This 512GB kit contains eight 64GB registered ECC RDIMMs built to the DDR5 6400 standard at 1.10V. It matches the rank, voltage and timing the motherboard's memory controller expects so every slot is recognised at full capacity and rated speed.

Registered DDR5 6400 interface limits

The 288-pin RDIMM form factor is required; UDIMM or SODIMM modules will not fit or function. Registered buffering offloads the memory controller to allow full population at the rated 6400MT/s, while ECC corrects single-bit errors on the fly.

512GB capacity with eight 64GB modules

Eight dual-rank 2Rx4 DIMMs fill all available slots for maximum density. Headroom ends when the board's supported capacity or population rules are reached; consult the system manual for approved configurations before installation.

Questions about this item

Should I buy the 512GB kit or build the same capacity from individual 64GB modules?

The kit ships as eight matched 64GB RDIMMs tested together, so the memory controller sees identical rank, timing and voltage across every slot — something that is not guaranteed when modules are purchased separately.

Will the DDR5-6400 CL52 rating actually run at that speed in my Supermicro H14DST-FL?

Yes, the modules are spec-matched to the board's qualified vendor list, so the memory controller will initialise them at 6400 MT/s with CL52 timings at 1.1V when all eight slots are populated.

What does the 288-pin RDIMM interface limit in a fully populated server?

The registered 288-pin RDIMM format is required by the H14DST-FL; it buffers address and command signals so the memory controller can drive all eight slots at the rated 6400 MT/s without signal degradation.
