Compatible Server Memory Kit

This 768GB DDR4 3200 registered ECC RDIMM kit is built for THINKMATE Supermicro SuperServer 740P-TR and 740P-TRT tower systems. It targets IT professionals who need maximum memory capacity for virtualisation, database or compute workloads on these qualified platforms. The twelve 64GB modules use 4Rx4 organisation to reach the total density.

Twelve-Module Registered Kit

The package delivers twelve matched 64GB RDIMMs that operate at 1.2V with CL22 latency. Registered buffering and on-die ECC protect data integrity across all channels, while the 4Rx4 layout allows the platform to address the full 768GB without exceeding rank limits per channel. No heat spreaders are included, relying on server chassis airflow.

Standard RDIMM Installation

Modules insert into the 288-pin DDR4 slots like any registered DIMM; the kit is keyed to prevent misalignment. Builders must populate slots in the order specified by the Supermicro manual to enable all twelve ranks per channel. Mixing with different ranks, speeds or unbuffered DIMMs will prevent the system from posting.

Questions about this item

Will the 12 registered DDR4 modules need any scheduled replacement or maintenance after installation?

The 768 GB kit uses 1.20 V registered DDR4 modules built for continuous server workloads; no scheduled swap is required.

What limit appears first when the 4Rx4 RDIMMs run at 3200 MT/s under sustained load?

The CL22 latency at 3200 MT/s is the primary timing constraint during prolonged heavy use.

How much heat or noise do the 288-pin modules add when the server runs all day?

The modules have no heat spreader and draw 1.20 V each, so they add minimal thermal load and produce no audible noise.
