2 TB DDR5 ECC RDIMM Kit for Supermicro H14DSG-OM

This 2 TB memory kit contains sixteen 128 GB DDR5-6400 registered ECC RDIMMs built to the exact specification of the Supermicro H14DSG-OM motherboard. The modules run at 1.1 V with CL52 latency and a 2Rx4 organisation so the board recognises the full capacity at rated speed.

Who this suits and who should look elsewhere

Ideal for administrators upgrading a Supermicro H14DSG-OM platform that requires registered ECC DDR5 RDIMMs in a fully populated configuration. Not suitable for systems that accept only unbuffered UDIMMs, SODIMM form factors, lower-density modules, or a different DDR generation.

Deciding specification: 16 x 128 GB 2Rx4

The kit delivers 2 TB through sixteen dual-rank 128 GB RDIMMs, each registered and ECC-enabled at DDR5-6400 CL52. This precise rank count, voltage, and timing combination determines whether the motherboard will initialise every slot at full capacity and rated frequency.
