768GB DDR4 ECC RDIMM kit for ThinkMate servers

This 768GB kit contains twelve 64GB DDR4 3200 registered DIMMs built for ThinkMate STX-WS-QS12-12E2 and STX-WS-QE36-14E2 Windows NAS platforms. It targets IT teams expanding memory in mission-critical server or workstation environments that require ECC integrity.

Twelve-module kit enables maximum density

The bundle delivers the full 768GB capacity across twelve 288-pin RDIMMs, allowing administrators to populate every supported slot in compatible ThinkMate systems. Registered buffering and on-die ECC maintain signal quality and data accuracy across all modules during sustained workloads.

DDR4 3200 interface caps bandwidth at PC4-25600

The DDR4 standard used here limits peak transfer rates to 25600 MT/s per module, so total throughput cannot exceed this ceiling regardless of workload. Systems needing higher memory bandwidth or lower latency than DDR4 3200 provides will require a platform migration to a newer memory generation.

Questions about this item

Will the 12 modules in this 768GB kit require any replacement or maintenance after installation?

The DDR4 RDIMM modules are solid-state components with no moving parts and no heat spreader, so no routine maintenance or scheduled replacement is needed once they are seated correctly in the 288-pin slots.

What limit appears first when the 4Rx4 registered ECC memory runs at 3200 MT/s under sustained load?

The CL22 CAS latency at 1.20 V sets the timing boundary; the memory controller will hit that latency ceiling before bandwidth or voltage limits become a factor.

How much heat and power does the 12-module kit produce when the workstation runs all day?

Each 64 GB module operates at 1.20 V without a heat spreader, so the kit draws modest power and relies on chassis airflow to dissipate the low heat generated by the registered DDR4 chips.
