64GB DDR4 3200 ECC RDIMM for Thinkmate Workstations

This 64GB registered DDR4 module runs at 3200MHz with CL22 latency and 1.2V operation. It is built for Thinkmate SBGrid-CryoEM workstations that require ECC RDIMM memory. The single 64GB stick uses a 4Rx4 organisation and 288-pin form factor.

Registered ECC design with major OEM chips

The registered buffer and ECC functionality work together to maintain data integrity under sustained server workloads. Samsung, Micron or Hynix components are used depending on supply. No heat spreader is included, so airflow in the chassis handles cooling directly.

Verify RDIMM slot support and rank limits

Confirm the motherboard accepts 4Rx4 registered DIMMs and that the memory controller supports this rank configuration. Check the system manual for maximum capacity per slot and total population rules before ordering.

Questions about this item

Will the 4Rx4 rank configuration require any future firmware updates on the THINKMATE SBGrid-CryoEM Workstation?

The module uses a fixed 4Rx4 organisation and 288-pin DDR4 interface; no firmware resides on the DIMM itself, so the workstation BIOS handles any rank-related initialisation without further updates.

At continuous 3200 MT/s throughput, does the CL22 latency or the 1.20 V supply become the first bottleneck?

CL22 sets the minimum cycle delay at 3200 MT/s, so latency is the limiting factor before the 1.20 V rail reaches its thermal ceiling.

With no heat spreader on the 64 GB RDIMM, how loud do the chassis fans get during all-day ECC workloads?

The bare DRAM runs at 1.20 V; typical server airflow keeps module temperatures low enough that chassis fan speeds remain at their idle acoustic profile.
