System-Specific DDR4 Kit for THINKMATE

This 256GB kit contains four 64GB DDR4 3200 ECC RDIMM modules built for the THINKMATE SBGrid-CryoEM Workstation. Registered buffering and on-die ECC protect data integrity in continuous compute workloads. The 1.2V operating voltage matches the platform’s standard memory power rail.

Limits of the DDR4 RDIMM interface

DDR4 3200 sets the maximum transfer rate at 25600 MT/s and the modules run at CL22 latency. Four ranks per module (4Rx4) increase electrical loading, so the motherboard must support quad-rank registered DIMMs at this speed. No heat spreaders are fitted, so chassis airflow must handle the thermal load.

The capacity that defines fit

Total capacity is 256GB across four 288-pin slots. If the workstation has fewer than four free DDR4 RDIMM slots, or if the platform’s qualified-vendor list caps memory below 256GB, this kit will not be fully usable.

Questions about this item

Should I choose the 4 x 64 GB kit or a different capacity?

This kit provides 256 GB total across four 64 GB modules, designed as a matched set for the THINKMATE SBGrid-CryoEM Workstation.

What does the DDR4 3200 rating mean once the memory is installed?

The modules run at 3200 MT/s with a CAS latency of 22 cycles at 1.20 V, delivering the rated PC4-25600 bandwidth in the workstation.

Is this ECC RDIMM compatible with standard DDR4 DIMM slots?

These are 288-pin DDR4 RDIMMs with registered buffering and ECC; they require a server or workstation motherboard that supports registered ECC memory.
