NEMIX RAM DDR5 4800 768GB Kit

This 768GB kit contains twelve 64GB DDR5 RDIMM modules built for the Supermicro H13SST-GC motherboard. It is designed for server administrators who need maximum registered ECC capacity in a single validated package. Buyers who need unbuffered UDIMMs or laptop SODIMMs cannot use this kit.

Registered ECC DDR5-4800 CL40 1.1V

The single specification that decides fitment is the registered ECC RDIMM architecture running at DDR5-4800 with CL40 timing at 1.1V. The memory controller expects this exact rank, voltage and timing combination to recognise full capacity and operate at rated speed.

288-Pin RDIMM Installation

Each module uses the standard 288-pin RDIMM form factor that seats directly into the motherboard DIMM slots. The main risk is ignoring the board's population order; the manual must be consulted for supported capacities and approved slot sequence before installation.

Questions about this item

Will the 4800 MT/s DDR5 kit run at its rated speed in a fully populated Supermicro H13SST-GC?

The kit is spec-matched to the board's memory controller and population rules, so all twelve slots recognise the modules at the rated DDR5 4800 speed.

What does the PC5-38400 label tell me about real-world bandwidth?

PC5-38400 is the peak transfer rate for DDR5 4800; the registered buffer lets every slot sustain that bandwidth when fully populated.

Does the 288-pin RDIMM form factor fit the H13SST-GC memory slots?

Yes, the motherboard requires 288-pin Registered DIMMs and this kit matches that exact form factor.
