128GB DDR5-6400 RDIMM kit for Supermicro H13SRH

This 128GB kit contains eight 16GB DDR5 registered ECC modules rated at 6400 MT/s with CL52 latency at 1.10V. It is built for servers and workstations that require the exact rank, voltage and timing the H13SRH memory controller expects.

Registered ECC limits and DDR5 population rules

Registered DIMMs offload the memory controller so all eight slots can run fully populated at rated speed while ECC corrects single-bit errors on the fly. DDR5 population rules vary by motherboard, so the manual must be consulted for supported capacities and approved slot order before installation.

1Rx8 rank and 1.10V voltage decide compatibility

The modules are single-rank 1Rx8 at 1.10V; if your platform requires dual-rank DIMMs or a different voltage the kit will not be recognised at full capacity or at its rated 6400 MT/s speed.

Questions about this item

Should I choose the 128GB 8x16GB kit or a different capacity for my Supermicro H13SRH?

The 128GB kit uses eight 16GB 1Rx8 RDIMMs, matching the board's DDR5 6400 registered ECC requirements for full-slot population.

What does DDR5 6400 CL52 mean for real-world server performance?

The modules run at 6400 MT/s with CAS latency 52 at 1.10V, delivering the rated throughput and error correction the H13SRH memory controller expects.

Does the 288-pin RDIMM interface limit speed or capacity on this motherboard?

The 288-pin registered DDR5 form factor is exactly what the H13SRH requires; it supports the kit's 6400 speed and 128GB total capacity when populated per the manual.
