Exact-fit 256GB DDR5 kit for Supermicro H13SRH

This 256GB kit contains eight 32GB DDR5-4800 registered ECC RDIMMs built to the precise rank, voltage and timing the H13SRH memory controller expects. Each module runs at 1.1V with CL40 latency and 2Rx8 organisation so the board recognises the full capacity at rated speed.

Suited for administrators populating every slot

Registered buffering offloads the memory controller while ECC corrects single-bit errors on the fly, preventing silent data corruption in production workloads. Builders using consumer UDIMMs, SODIMMs or non-ECC modules should look elsewhere because the board requires registered DDR5 RDIMMs.

288-pin registered DDR5 RDIMM form factor

The kit delivers 288-pin DDR5 RDIMMs at 4800 MT/s (PC5-38400) with 1.1V operation and CL40 timing, matching the physical and electrical interface the H13SRH demands. Verify your system manual for approved population order and maximum supported capacity before installation.

Questions about this item

Should I buy the 8 x 32 GB kit or a different capacity for my Supermicro H13SRH?

The 256 GB kit contains eight 32 GB modules and is validated for the H13SRH; choose it when you need the full 256 GB population.

What does the 4800 MHz rating mean once the modules are installed in the server?

The memory controller will run the kit at DDR5 4800 (PC5 38400) with CL40 latency at 1.1 V, delivering the rated throughput across all eight slots.

Is the 288 pin RDIMM interface compatible with my motherboard and what does it limit?

The H13SRH requires 288 pin registered DDR5 RDIMMs; this kit matches that form factor and the registered design lets all eight slots operate at full capacity.
