Exact-match DDR5-6400 kit

This 128 GB kit consists of two 64 GB DDR5 Registered DIMMs rated at 6400 MT/s with CL52 latency and 1.1 V operation. The modules use a 2Rx4 organisation and on-die ECC for single-bit error correction in server workloads.

Suits Supermicro H13SSL-N builds

It is designed for administrators populating the Supermicro H13SSL-N motherboard with the precise rank, voltage and timing the platform expects. Systems that require unbuffered UDIMMs, SODIMMs or a different DDR generation will not accept these modules.

Handles full-capacity registered loads

Registered buffering lets every slot run fully populated at the rated 6400 MT/s speed while ECC protects data integrity. The kit provides 128 GB total capacity; configurations needing more memory or a different form factor must use other modules.

Questions about this item

Does my Supermicro H13SSL-N motherboard need to support 288-pin DDR5 RDIMM slots for this kit to work?

Yes, this kit uses the 288-pin DDR5 RDIMM form factor that the H13SSL-N requires; it will not fit UDIMM or SODIMM sockets.

Can I mix these 2Rx4 Registered ECC modules with older single-rank DDR5 RDIMMs already installed in the server?

Mixing ranks is possible if the motherboard manual allows it, but population rules usually require identical rank and capacity per channel for stable operation at 6400 MT/s.

How do I confirm the kit is running at its rated 6400 MT/s CL52 after installation?

Check the BIOS memory information or an OS tool such as dmidecode; both should report 6400 MT/s, CL52, 1.1 V and 2Rx4 Registered ECC for each module.
