Capacity and fit

This NEMIX RAM kit delivers 1.5TB across 12 modules of 128GB each, built as DDR5-4800 RDIMM with ECC and registered buffering. It is made for the Supermicro H13SST-GC motherboard and targets servers that need maximum registered capacity with error correction.

Pre-install checks

Verify the motherboard manual for supported capacities per slot, the required DIMM population order and any BIOS version minimums before ordering. The kit uses 288-pin RDIMM form factor so the board must accept registered modules and not unbuffered or SODIMM types.

Build and daily use

Modules operate at 1.1V with CL40 timing and 2Rx4 organisation using major OEM chips without heat spreaders. Registered architecture reduces electrical load on the memory controller when all slots are populated while ECC corrects single-bit errors to protect data integrity in production workloads.

Questions about this item

Does the 1.5TB kit ship as twelve 128GB modules or do I need to buy additional DIMMs?

The kit contains exactly twelve 128GB DDR5 RDIMMs, giving 1.5TB total capacity with no extra modules required.

Should I choose a different speed or latency if my Supermicro H13SST-GC supports faster DDR5?

This kit runs at DDR5 4800 CL40 1.1V 2Rx4, the exact specification the board's memory controller expects for full-capacity recognition and rated-speed operation.

What does the 4800 MT/s rating mean when all twelve slots are populated on this motherboard?

Registered ECC architecture lets every slot run fully populated at the rated 4800 MT/s while ECC corrects single-bit errors on the fly.
