System-Specific ECC RDIMM Kit

This 32 GB kit contains two 16 GB DDR4 3200 registered DIMMs built for the THINKMATE SBGrid-CryoEM Workstation. ECC and registered signalling protect data integrity in long-running scientific workloads. Modules run at 1.20 V with CL22 timing and use 2Rx8 organisation across 288 pins.

For memory-bound Cryo-EM pipelines

Suits administrators expanding a validated THINKMATE SBGrid-CryoEM node where ECC RDIMMs are required. Not for desktop boards that accept only unbuffered non-ECC UDIMMs. Not for systems limited to lower DDR4 speeds or different pin counts. Not for buyers needing heat spreaders or RGB lighting.

Registered ECC with 2Rx8 organisation

The decisive spec is the combination of registered ECC operation and dual-rank 2Rx8 layout at DDR4 3200. Motherboards that demand registered modules and support this rank configuration will accept the kit; those requiring unbuffered or single-rank DIMMs will not.

Questions about this item

What does the 3200 MT/s rating mean once these modules are installed in the ThinkMate workstation?

The modules will run at up to 3200 MT/s, delivering PC4-25600 bandwidth for the SBGrid-CryoEM workload.

How does the registered ECC RDIMM interface affect what the memory controller can do?

The registered design adds a clock cycle of buffering, while ECC corrects single-bit errors, both required by the workstation motherboard.

Will the 288-pin RDIMM sticks fit the ThinkMate SBGrid-CryoEM DIMM slots without a heat spreader?

Yes, the 288-pin DDR4 RDIMM form factor matches the workstation slots, and the low-profile design has no spreader to clear.
