NEMIX RAM
Eight 16 GB DDR4 3200 ECC registered DIMMs totalling 128 GB at 1.2 V for the Gigabyte WRX80-SU8-IPMI
This 128GB kit contains eight 16GB DDR4 3200 registered DIMMs built for the Gigabyte WRX80-SU8-IPMI motherboard. ECC and registered operation protect data integrity in server and workstation workloads. The modules run at 1.20V with CL22 latency.
Each DIMM draws 1.20V without a heat spreader, relying on chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller during sustained use. Power draw stays consistent with standard DDR4 RDIMM specifications.
The 288-pin RDIMM form factor fits only DDR4 RDIMM slots; it will not work in UDIMM or SO-DIMM sockets. Eight modules fill all channels on the target board for maximum bandwidth. No heat spreader means low-profile clearance for tight server chassis.

Power off the server, open the chassis, and insert each 16 GB module into the eight DIMM slots following the motherboard's channel-population diagram; the step most people miss is seating every module until both retention clips click, otherwise the system will not recognise the full 128 GB kit.
The modules have no heat spreaders and run at 1.20 V, so the only recurring task is keeping the server's airflow paths clean; if a module ever fails the ECC scrub will flag it and the individual 16 GB stick can be swapped without replacing the whole kit.
The registered 2Rx8 organisation and CL22 latency set the throughput ceiling; under continuous heavy traffic the memory controller hits its maximum sustainable bandwidth before temperature or voltage (1.20 V) become bottlenecks.
