128GB ECC RDIMM kit for THINKMATE SBGrid-CryoEM

This 128GB kit contains two 64GB DDR4 3200 registered DIMMs built for the THINKMATE SBGrid-CryoEM Workstation. Each module runs at PC4-25600 with CL22 latency and 1.20V voltage. The 4Rx4 organisation and ECC registration target data-integrity workloads on qualified server boards.

Sustained-load behaviour

Registered buffering and on-die ECC keep signal integrity stable during long compute runs on the SBGrid-CryoEM platform. The 4Rx4 density allows high capacity per channel without exceeding the workstation's qualified memory topology. Modules are stress-tested under load before shipment to verify reliability in continuous operation.

Pre-order checklist

Confirm the workstation accepts 288-pin DDR4 RDIMMs at 3200 MT/s with 4Rx4 rank layout and 1.20V operation. Verify the motherboard supports 128GB total capacity across two slots and that the BIOS recognises registered ECC modules. Cross-reference the MR25600-944K2 part number with the system's qualified-vendor list before purchase.

Questions about this item

How much power does the 128GB DDR4 3200 CL22 ECC RDIMM kit draw at 1.2V when running continuously?

Each 64GB module operates at 1.2V; total draw depends on the motherboard's memory controller and workload, so consult the workstation's power specifications for exact figures.

What motherboard slot and chipset support are required for these 288-pin 4Rx4 registered DIMMs to function?

The kit needs a DDR4 RDIMM slot on a motherboard qualified for 4Rx4 registered ECC modules; verify the THINKMATE SBGrid-CryoEM workstation's memory QVL before installing.

Will the 3200 MT/s CL22 registered ECC modules run stably alongside slower DDR4 RDIMMs already installed in the workstation?

The memory controller will clock all installed RDIMMs to the lowest common speed and latency; mixing ranks or speeds can reduce bandwidth or prevent boot, so match specifications exactly.
