Exact-Match Server Memory Kit

This 1.5TB kit contains twelve 128GB DDR5 RDIMM modules built for the Supermicro H14SST-G motherboard. Each module runs at 4800MHz with CL40 timing at 1.1V using a 2Rx4 registered ECC design. The specification matches the board's memory controller requirements for full-capacity recognition.

Installation Notes

The 288-pin RDIMM form factor fits only registered DIMM slots; UDIMM or SODIMM slots will not accept these modules. Populate all twelve slots following the motherboard manual's exact population order to avoid boot failures or reduced capacity. No heat spreaders are present, so ensure adequate chassis airflow.

Suited For High-Density Servers

This kit suits administrators maximising memory density on a validated H14SST-G platform for virtualization or database workloads. It is not for systems that require UDIMM or SODIMM form factors, builds needing lower total capacity, or boards that do not support registered ECC DDR5 at this density.
