Capacity and Compatibility

This 384GB kit contains twelve 32GB DDR4 3200 registered DIMMs built for THINKMATE Supermicro SuperServer models including the 620P-TR, 620P-TRT, 220P-C9R and 220P-C9RT. It targets administrators who need maximum memory density in qualified server platforms.

Registered ECC Design

Each module uses a 2Rx4 organisation with on-die ECC and a registered buffer to reduce electrical load on the memory controller. The 288-pin RDIMM form factor fits standard DDR4 server slots and operates at 1.20V without a heat spreader, relying on chassis airflow for cooling.

Upgrade Path

The kit replaces lower-capacity DDR4 RDIMM sets or mixed-rank configurations that limit total addressable memory. The jump is worthwhile when workloads such as virtualisation, in-memory databases or large-scale compute require the full 384GB ceiling and the platform's qualified vendor list includes this part number.

Questions about this item

Does the DDR4 3200 PC4-25600 interface cap real-world throughput below the rated speed?

The modules run at DDR4 3200 (PC4-25600) with CL22 latency; actual throughput depends on the server memory controller and populated channel count.

What physical space and slot type are required for the 12-module 288-pin RDIMM kit?

Twelve 288-pin DDR4 RDIMM slots are needed; each module is a standard-height registered DIMM without a heat spreader.

How are the 2Rx4 registered ECC modules installed, and which step is often missed?

Power down, open the chassis, align each 288-pin RDIMM with the keyed slot and press until the ejectors lock; the step often missed is verifying the motherboard supports 2Rx4 registered ECC population rules for all twelve slots.
