Exact-Match Server Upgrade

This 192GB kit delivers four 48GB DDR5 RDIMM modules rated at 6400 MT/s with CL52 latency and 1.1V operation. It is built specifically for the Supermicro H13SSW motherboard, matching the registered ECC 2Rx8 layout that the board's memory controller expects for full-capacity recognition.

Capacity and Headroom

Populating all slots with 48GB registered DIMMs provides 192GB of error-correcting memory for virtualization hosts, database nodes, or compute clusters. The registered architecture keeps the memory controller stable when every channel is fully loaded, while ECC corrects single-bit errors before they affect workloads.

Verified Fitment and Support

The kit is validated against the H13SSW's population rules, so the 288-pin RDIMM form factor installs without UDIMM or SODIMM mismatches. Buyers who need a different total capacity, a UDIMM form factor, or non-ECC modules should look elsewhere. Lifetime replacement coverage and US-based technical support are included.

Questions about this item

Will this 192GB DDR5 6400 kit run at full speed in all four slots of my Supermicro H13SSW?

The registered 2Rx8 design is built for full-population stability on the H13SSW, so the memory controller recognises all four 48GB modules at the rated 6400 MT/s without down-clocking.

How can I confirm the ECC RDIMM kit is operating correctly after installation?

Enter the BIOS and verify that all 192GB are detected at DDR5-6400 with CL52 timings at 1.1V, then run a memory diagnostic to confirm ECC error correction is active.

What exactly is included in the MR51200-4828K4 package and do I need anything extra?

The box contains the four 48GB 288-pin DDR5 ECC RDIMM modules only; no heat spreaders or additional cables are supplied, and no extra parts are required for installation on the H13SSW.
