384GB DDR4 3200 ECC RDIMM kit

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.

Sustained load behaviour with 4Rx4 organisation

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.

Installation notes for six-module population

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.

Questions about this item

How much power does the 6x64GB kit draw at 1.20V when the server runs continuously?

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.

Which ThinkMate Supermicro models must the buyer already own for this MR25600-944K6 kit to be compatible?

The kit is validated for ThinkMate Supermicro SuperServer 620P-TR, 620P-TRT, 220P-C9R and 220P-C9RT systems.

Will these 4Rx4 CL22 modules work alongside older 2Rx4 DDR4 DIMMs already installed in a ThinkMate server?

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.
