Exact-match DDR5-6400 kit for Supermicro H13SSW

This NEMIX RAM kit delivers 128 GB across eight 16 GB DDR5 RDIMMs rated at 6400 MT/s with CL52 latency and 1.10 V operation. Registered ECC construction with 1Rx8 organisation matches the memory controller requirements of the Supermicro H13SSW motherboard so the full capacity is recognised at rated speed.

Suited for administrators populating every slot

The registered design offloads the memory controller allowing all eight slots to run fully populated while ECC corrects single-bit errors on the fly. Buyers who need unbuffered UDIMMs, SODIMMs, lower capacities, or modules validated for a different server platform should look elsewhere.

Straightforward 288-pin RDIMM installation

Modules seat in the standard 288-pin DDR5 RDIMM sockets; follow the motherboard manual for the approved population order to avoid a no-post condition. The most common issue is installing DIMMs in the wrong sequence or mixing ranks, which prevents the system from recognising the full 128 GB.

Questions about this item

What motherboard must I already have for this 128GB kit to be recognized at full capacity and rated speed?

The kit is spec-matched for the Supermicro H13SSW motherboard and requires that board's 288-pin RDIMM slots to run at DDR5-6400 with CL52 timings.

How do the 1Rx8 registered ECC modules behave when installed alongside other registered DIMMs already in the server?

Registered architecture offloads the memory controller so every slot runs fully populated at full capacity while ECC corrects single-bit errors on the fly.

How can I verify the kit is running at its rated DDR5-6400 CL52 1.10V settings after installation?

Check the BIOS or UEFI memory information screen — it should show all eight 16GB modules at 6400 MT/s, CAS latency 52, and 1.10 V.
