System-Specific 512GB DDR4 Kit

This 512GB kit contains eight 64GB registered ECC DDR4 modules built for the THINKMATE SBGrid-CryoEM workstation. It targets IT teams running memory-intensive scientific workloads that require error correction and registered signalling.

Straightforward DIMM Installation

Modules seat in standard 288-pin DDR4 RDIMM slots without tools; the kit arrives as a matched set to avoid mixing ranks. The main risk is populating slots in an order the workstation manual does not support, which can prevent the system from posting.

Registered ECC With 4Rx4 Organisation

Each module uses a 4Rx4 layout at CL22 latency and 1.20V, delivering registered ECC operation at DDR4 3200 speed. Workstations that need unbuffered memory or a different rank configuration cannot use this kit.

Questions about this item

How do I verify the kit is running at 3200 MT/s with CL22 after installation?

Enter the system BIOS or UEFI and confirm all eight modules are detected at 512GB total with the speed showing 3200 MT/s and CL22 timings; then run a memory stress test to confirm stability under load.

What comes in the box and is anything else required to install the 8 modules?

The package contains eight 64GB DDR4 3200 ECC registered RDIMM modules; no additional parts are needed for installation in a compatible THINKMATE SBGrid-CryoEM workstation.

Which capacity option should I choose for the THINKMATE SBGrid-CryoEM workstation?

This kit provides 512GB total across eight 64GB modules and is the only capacity configuration offered for this part number.
