Exact-match upgrade for Supermicro H13SST-G

This 192GB kit contains four 48GB DDR5 4800 RDIMM modules built to the board's precise rank, voltage and timing requirements. Registered ECC architecture offloads the memory controller so every slot runs fully populated at rated speed. Designed for enterprise workloads that demand full-capacity stability and on-the-fly single-bit error correction.

Check your system manual before ordering

Server memory support varies by model and BIOS revision. Verify the motherboard manual for approved DIMM population order, maximum supported capacity per slot and any required firmware updates. Confirm the board uses 288-pin RDIMM slots rather than UDIMM or SODIMM form factors. Ensure the 1.1V operating voltage matches platform specifications.

Kit delivers four matched modules for full

The package provides four 48GB RDIMMs so all available channels can be filled in a single step. Matched capacity, timing and rank across the set removes the guesswork of mixing sticks from different lots. Registered buffering and ECC work together to maintain data integrity under sustained load without additional software configuration.

Questions about this item

Does the kit include anything besides the four 48 GB RDIMMs, or do I need to buy heat spreaders separately?

The package contains only the four 48 GB DDR5 4800 CL40 1.1 V 2Rx8 registered ECC modules; no heat spreaders or extra accessories are included and none are required for installation.

Should I choose this 192 GB kit or a different capacity for the Supermicro H13SST-G?

This 192 GB kit matches the board's supported population rules with four 2Rx8 RDIMMs running at DDR5 4800; select it when your workload needs the full 192 GB, otherwise choose a smaller kit that follows the same rank and voltage spec.

What does the 4800 MT/s rating actually deliver once the modules are seated in the server?

The memory controller will recognise the 4800 MT/s PC5-38400 speed at the rated 1.1 V and CL40 latency, giving full bandwidth across all four slots with registered buffering and ECC active.
