Exact-match 128 GB DDR5-6400 RDIMM

This registered ECC module delivers 128 GB at 6400 MT/s with CL52 timing and 1.1 V operation. It is built for the Supermicro H13DSH motherboard and uses the 288-pin RDIMM form factor that board requires.

Registered DDR5 limits

The RDIMM architecture buffers address and command signals so the memory controller can drive every slot at full speed even when fully populated. ECC corrects single-bit errors on the fly, but the module will not work in systems that accept only unbuffered UDIMMs or SODIMMs.

Major OEM chips no spreader

Chips from Samsung Micron or Hynix are mounted on a bare PCB without a heat spreader, relying on server chassis airflow for cooling. The 2Rx4 rank organisation fits the board's population rules, and the 288-pin keying prevents mis-installation in incompatible slots.

Questions about this item

Should I pick the 128 GB DDR5-6400 CL52 2Rx4 registered ECC kit or a different capacity for my Supermicro H13DSH?

This kit is the exact-match 128 GB DDR5-6400 (PC5-51200) 2Rx4 registered ECC module at 1.1 V CL52 that the H13DSH memory controller expects, so it is recognised at full capacity and rated speed; choose a different capacity only if your board manual lists it in the approved population table.

What does the DDR5-6400 (PC5-51200) rating mean once the module is installed in the server?

The module will run at 6400 MT/s with CL52 latency at 1.1 V, delivering the full PC5-51200 bandwidth the platform specifies when all slots are populated with registered DIMMs.

How does the 288-pin registered ECC RDIMM interface affect real-world stability and capacity limits?

The registered buffer offloads the memory controller so every slot can run fully populated at 128 GB per DIMM, while on-die ECC corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots.
