THINKMATE DDR4 3200 ECC RDIMM kit

This 256GB kit contains eight 32GB DDR4 3200 registered ECC modules built for the THINKMATE SBGrid-CryoEM Workstation. CL22 timing at 1.2V provides stable throughput for memory-intensive scientific workloads. The 2Rx8 organisation and registered design suit multi-socket server platforms that require error-correcting memory.

Verify DIMM slots and registered ECC support

Confirm the workstation has eight free 288-pin DDR4 slots and that its BIOS accepts registered ECC RDIMMs at 3200 MT/s. Unbuffered or non-ECC modules will not operate correctly in this configuration. Check the system manual for maximum capacity per channel and any population rules before ordering.

Registered design needs compatible server platform

The modules require a motherboard wired for registered DDR4 ECC memory and will not function in consumer desktop boards. They free unbuffered slots for other uses while delivering 256GB total capacity across eight channels. No heat spreader is fitted, so ensure case airflow meets the platform's thermal requirements.

Questions about this item

Does the 256GB kit ship as eight 32GB modules or must extra sticks be purchased?

The kit contains eight 32GB DDR4 3200 RDIMMs, giving 256GB total; no additional modules are required.

Should I choose this CL22 2Rx8 kit or a lower-latency alternative for the THINKMATE SBGrid-CryoEM Workstation?

This CL22 2Rx8 registered ECC kit is validated for the THINKMATE SBGrid-CryoEM Workstation; a different latency or rank configuration may not be supported.

Will the advertised 3200 MT/s speed run at 3200 MT/s once installed in the workstation?

The modules are rated DDR4 3200 (PC4-25600) and will operate at that speed when the workstation's memory controller and BIOS support it.
