192GB DDR5 ECC RDIMM kit

This 192GB kit contains four 48GB DDR5-4800 registered ECC RDIMMs built for the Supermicro H13DSG-O-CPU motherboard. The modules run at CL40 with a 1.10V operating voltage and use a 2Rx8 rank layout. Registered buffering lets every slot stay fully populated at rated speed. ECC corrects single-bit errors to prevent silent data corruption in production workloads.

Suits verified Supermicro servers.

The kit is validated for the Supermicro H13DSG-O-CPU motherboard and its specific memory-population rules. Builders using a different motherboard, a workstation that requires UDIMMs, or a system that cannot accept registered DIMMs should look elsewhere. Laptops and consumer desktops that only support unbuffered memory are also incompatible. Always consult your system manual for supported capacities and approved DIMM installation order before purchasing.

Registered ECC RDIMM form factor

The 288-pin registered RDIMM form factor is the single specification that decides fitment. This board requires registered (buffered) DIMMs, not UDIMMs or SODIMMs. The 2Rx8 rank structure and 1.10V voltage must match the memory controller expectations for full-capacity recognition. If your platform calls for a different form factor or voltage, this kit will not work.
