2 TB DDR5 ECC RDIMM kit for Supermicro H13DSH

This 2 TB kit contains sixteen 128 GB modules built to the DDR5 6400 standard with CL52 latency and 1.1 V operation. It is a registered ECC RDIMM designed for servers that require 288 pin memory and full population across all slots.

Verified fitment and enterprise stability

The modules are validated for the Supermicro H13DSH motherboard and use the 288 pin RDIMM form factor that board requires. Registered buffering reduces electrical load on the memory controller while ECC corrects single bit errors to prevent silent data corruption.

Check your system configuration before ordering

Server memory support varies by model so consult your motherboard manual for approved population rules and maximum capacity per channel. Confirm the board accepts 2Rx4 registered DIMMs at the rated speed and voltage before purchase.

Questions about this item

Does the DDR5 6400 interface cap at PC5-51200 on the Supermicro H13DSH?

Yes, the kit is specified at DDR5 6400 (PC5-51200) and the H13DSH memory controller will run it at that rated speed when populated per the board's rules.

What physical slot and form factor do the 16 modules need on the H13DSH?

Each 128 GB module is a 288-pin registered RDIMM; the H13DSH requires exactly this form factor, not UDIMM or SODIMM.

What is the correct installation sequence for all 16 RDIMMs on the H13DSH?

Follow the motherboard manual's DIMM population order; the common mistake is filling slots sequentially instead of the prescribed interleaved pattern for full 2 TB recognition.
