THINKMATE DDR5 4800 ECC RDIMM 192GB Kit

This 192GB kit contains twelve 16GB DDR5 4800 registered DIMMs built for THINKMATE Supermicro SuperServer 611C-TN4R and 621C-TN12R platforms. ECC and registered buffering protect data integrity in mission-critical server and workstation environments. The modules operate at 1.1V with CL40 latency.

288-Pin DDR5 RDIMM Registered Server Memory

Each 1Rx8 module fits a standard 288-pin DDR5 RDIMM slot and requires a motherboard that supports registered ECC memory. The registered design reduces electrical load on the memory controller, freeing the platform to populate all available channels. No heat spreader is included, so airflow across the modules must be provided by the chassis.

192GB Capacity with DDR5 4800 Headroom

The 192GB total capacity handles large virtualisation clusters, in-memory databases and heavy compute workloads. Twelve 16GB ranks at 4800 MT/s deliver high bandwidth while the CL40 timing keeps latency predictable. Workloads exceeding 192GB or requiring faster DDR5 speeds will need a larger kit or higher-frequency modules.

Questions about this item

At what sustained load does the CL40 latency become the first bottleneck?

CL40 latency limits throughput whenever the memory controller issues back-to-back read commands faster than the 40-cycle window allows; under continuous bandwidth-heavy workloads this timing ceiling appears before capacity or voltage limits.

How much heat and power does the 1.10 V kit produce when running all day?

Each 16 GB module operates at 1.10 V without a heat spreader, so total power draw scales with the 12-module population and airflow must handle the combined thermal output of all ranks.

Which Thinkmate Supermicro SuperServer models must I already own for this 288-pin DDR5 RDIMM kit to work?

The kit is validated for the SuperServer 611C-TN4R and SuperServer 621C-TN12R; both platforms accept 288-pin DDR5 ECC registered DIMMs at 4800 MT/s.
