Capacity and Configuration

This 128GB kit contains eight 16GB DDR5 RDIMM modules rated at 6400 MT/s with CL52 latency and 1.1V operation. The 1Rx8 registered ECC design matches the Supermicro H13DSH memory controller requirements for full-capacity recognition at rated speed.

Headroom and Limits

Eight registered DIMMs populate every slot the board provides, delivering maximum supported capacity with ECC protection that corrects single-bit errors on the fly. The kit runs at its specified 6400 MT/s when the platform memory population rules are followed; exceeding the board's validated configuration is not supported.

Build Integration

The 288-pin RDIMM form factor fits only motherboards wired for registered DDR5 memory — UDIMM or SODIMM boards will not accept these modules. Installation order must follow the Supermicro H13DSH manual to ensure all 128GB are recognised and stable.

Questions about this item

Will this 128GB DDR5-6400 RDIMM kit work in a Supermicro H13DSH alongside my existing DDR5 modules?

The kit is verified for the Supermicro H13DSH and uses the 288-pin Registered RDIMM form factor that board requires. Mixing speeds or ranks is not addressed in the supplied data.

How can I confirm the 128GB kit is running at DDR5-6400 CL52 1.1V after installation?

Check the BIOS memory information screen or a tool such as dmidecode; it should report 6400 MT/s, CL52 latency, 1.10V voltage and 1Rx8 registered ECC for each of the eight 16GB modules.

What comes in the box and do I need to buy anything else for the Supermicro H13DSH?

The package contains the 128GB kit as eight 16GB DDR5-6400 1Rx8 ECC RDIMMs. No extra parts are included or required for installation in the H13DSH.
