THINKMATE SuperServer DDR4 3200 ECC RDIMM kit

This 64 GB kit contains eight 8 GB DDR4 3200 registered ECC modules built for THINKMATE SuperServer platforms. It targets administrators who need validated, error-correcting memory for 620P-TR, 620P-TRT, 220P-C9R and 220P-C9RT systems.

Registered 288-pin modules for populated server

Each stick is a 1Rx8 288-pin RDIMM running at 1.20 V with CL22 latency. The registered buffer reduces electrical load on the memory controller, allowing all eight slots to be filled without signal degradation. No heat spreaders are fitted, so airflow clearance follows the chassis design.

Eight matched modules tested under load

The kit ships as a single 8 x 8 GB package, stress-tested at rated speed before dispatch. Matching rank, voltage and timing across every module eliminates mixed-DIMM timing issues during POST and keeps the memory subsystem stable under sustained workloads.

Questions about this item

Will the registered design and 1.20V voltage limit how long the kit can run at DDR4 3200 under sustained load?

The 1Rx8 registered modules operate at 1.20V with CL22 timing, a combination built for continuous server workloads without thermal throttling.

How much heat or fan noise will eight 288-pin RDIMMs add to a Supermicro SuperServer chassis running all day?

Bare modules without heat spreaders rely on chassis airflow; in a properly ventilated Thinkmate system they add minimal acoustic load.

Which Thinkmate Supermicro models must I already own for this 8x8GB kit to work?

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