NEMIX RAM
A 384 GB DDR4-3200 ECC registered server memory kit of six 64 GB RDIMMs at CL22 and 1.2 V, validated for Thinkmate Supermicro SuperServer 620 and 220 series
This 384GB kit contains six 64GB registered DDR4 modules running at 3200 MT/s with CL22 latency. It is built for THINKMATE Supermicro SuperServer platforms such as the 620P-TR, 620P-TRT, 220P-C9R and 220P-C9RT. The ECC RDIMM design targets administrators who need maximum capacity and error correction in multi-socket server chassis.
Each module uses a 4Rx4 organisation and operates at 1.20V, allowing the memory controller to interleave across ranks during long-running workloads. Registered buffering reduces electrical load on the bus, helping maintain stability when all 384GB are populated and the system runs continuous database or virtualisation tasks. Samsung, Micron or Hynix major-OEM chips are selected to meet the PC4-25600 specification under extended thermal stress.
The 288-pin RDIMM form factor fits standard DDR4 server slots, but every slot must be filled to reach the rated capacity, so verify the motherboard supports six modules per CPU socket. No heat spreaders are present, which eases clearance around tall CPU coolers but leaves the DRAM exposed to direct airflow. Consult the Supermicro memory population guide for the correct slot order; incorrect sequencing is the most common cause of POST failures with this density.

Each module operates at 1.20V DDR4 standard voltage. Total system power depends on the platform's memory controller and how many ranks are active under load.
The kit is validated for ThinkMate Supermicro SuperServer 620P-TR, 620P-TRT, 220P-C9R and 220P-C9RT systems.
Mixing 4Rx4 and 2Rx4 ranks is not recommended; the memory controller will typically down-clock all channels to the lowest common speed and may disable multi-rank features.
