Exact-match DDR5-6400 ECC RDIMM kit

This 512GB kit delivers eight 64GB registered ECC modules built to the DDR5-6400 CL52 1.1V specification. It targets administrators upgrading a Supermicro H14DSG-O-CPU motherboard that demands the precise rank, voltage and timing the board's memory controller expects.

288-pin RDIMM population for full capacity

Each module uses the 288-pin registered RDIMM form factor the H14DSG-O-CPU requires, not a UDIMM or SODIMM. The buffered architecture offloads the memory controller so all slots can run fully populated at the rated speed while ECC corrects single-bit errors on the fly.

512GB headroom with 2Rx4 organisation

Eight dual-rank 2Rx4 modules provide 512GB of addressable memory for large virtualisation clusters, in-memory databases or HPC workloads. Capacity stops at the kit size; boards with fewer slots or lower per-slot limits will not accept the full complement.

Questions about this item

Will the 1.1 V DDR5 modules hit a thermal limit when all eight slots stay fully populated 24/7?

Registered ECC RDIMMs offload the memory controller so every slot can run fully populated at rated speed without throttling.

How much noise or extra heat does a 512 GB kit of 1.1 V RDIMMs add to a server running all day?

The modules have no heat spreaders and operate at standard 1.1 V, so they add minimal thermal load and produce no audible noise.

What must the motherboard already provide for this 288-pin DDR5 RDIMM kit to work?

The board must support DDR5 Registered ECC RDIMMs, 2Rx4 rank structure, 1.1 V operation and eight populated slots per its population rules.
