Server memory kit for Supermicro H13DSH

This 256GB kit contains eight 32GB DDR5 RDIMM modules rated at 6400MHz with CL52 latency and 1.1V operation. It is built for the Supermicro H13DSH motherboard and uses registered ECC architecture for enterprise workloads.

Registered ECC DDR5 constraints

Registered DIMMs buffer address and command signals so the memory controller can drive all eight slots at the rated 6400MHz speed. ECC corrects single-bit errors automatically. The modules require a motherboard that supports 288-pin DDR5 RDIMMs with 2Rx8 organization and 1.1V voltage.

Verify your server configuration

Check the H13DSH manual for approved DIMM population order and maximum supported capacity per slot before ordering. Ensure the BIOS is updated to a version that recognises this exact 256GB 8x32GB configuration at full speed.

Questions about this item

Should I pick the 8-module 256 GB kit or buy single 32 GB sticks to reach the same total?

The kit delivers eight matched 32 GB RDIMMs tested together, so the memory controller sees identical rank, voltage and timing across every slot. Buying singles risks mixed batches that can prevent full-speed operation or cause population errors on the Supermicro H13DSH.

Will the DDR5-6400 rating actually run at 6400 MT/s in my H13DSH server?

Yes, the modules are spec-matched to the board's memory-controller requirements — 1.1 V, CL52, 2Rx8 registered — so the platform will recognise the full 256 GB and operate at the rated 6400 MT/s without down-clocking.

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

The registered design buffers address and command signals, letting the H13DSH run all eight slots fully populated at 6400 MT/s. Unbuffered UDIMMs would hit electrical-loading limits well before that.
