192GB DDR5 ECC RDIMM kit for Supermicro H13SSH

This 192GB kit delivers twelve 16GB DDR5 4800 Registered ECC modules built to the exact rank, voltage and timing the Supermicro H13SSH motherboard expects. It targets administrators who need the full 192GB capacity recognised at rated speed without manual tuning.

Registered ECC stability at full population

Registered buffering offloads the memory controller so all twelve slots run fully populated at 4800 MT/s, while ECC corrects single-bit errors on the fly to prevent silent data corruption. The 1Rx8 organisation and 1.1V operation match the board's population rules, so headroom ends when the platform's maximum supported capacity is reached.

288-pin DDR5 RDIMM form factor

The modules use the 288-pin DDR5 RDIMM form factor required by the H13SSH; they are not compatible with UDIMM or SODIMM slots. Verify your system manual for approved DIMM population order and maximum capacity before purchase.

Questions about this item

Will this 12-module DDR5 4800 kit run at rated speed alongside any existing RDIMMs I keep in my Supermicro H13SSH?

The kit is an exact-match upgrade for the H13SSH; populate all 12 slots with these 1Rx8 Registered ECC modules at 1.1 V CL40 and the memory controller will recognise the full 192 GB at DDR5 4800 without down-clocking.

How can I verify the kit is operating at DDR5 4800 CL40 with ECC active after installation?

Check the BIOS memory information screen — it should show 192 GB total, DDR5 4800 MT/s, CL40 timings, 1.1 V, and ECC Registered status for each of the 12 DIMMs.

What exactly ships in the box and is anything else required to install it?

The package contains the 12 x 16 GB DDR5 4800 288-pin ECC Registered RDIMMs only; no heat spreaders, cables or tools are included and none are required for standard server DIMM slots.
