32GB DDR4 3200 Kit for Thinkmate Workstations

This 32GB kit contains two 16GB DDR4 3200 UDIMM modules rated at CL22 and 1.2V. It is built for Thinkmate VSX-R5-140V12, VSX-R5-340R and VSX-R5-340R7 workstations that accept non-ECC unbuffered memory. The dual-rank 2Rx8 organisation suits systems designed for that density.

Check motherboard slots and memory mode

Verify the workstation has two free 288-pin DDR4 slots and that the board runs unbuffered non-ECC UDIMMs. Confirm the BIOS can operate at 3200 MT/s or will downclock automatically. Ensure the platform does not require registered or ECC modules, because this kit provides neither.

Adds 32GB without ECC overhead

The kit plugs directly into standard DDR4 UDIMM slots and draws 1.2V, leaving registered-channel capacity untouched. It frees registered DIMM slots for other workloads while expanding main memory for applications that do not need error correction. No heat spreader means the modules fit tight spaces where taller sticks would clash.

Questions about this item

Does the kit include only the two 16 GB UDIMMs or are any tools or cables supplied?

The package contains the 32 GB kit made up of two 16 GB DDR4 3200 CL22 2Rx8 1.2 V 288-pin UDIMM modules and nothing else.

Is there a single 32 GB stick option or is the 2 x 16 GB kit the only capacity offered?

This part number MD25600-628K2 is sold as a matched 2 x 16 GB kit; no other capacity or single-module version is listed for this SKU.

Will the CL22 latency at 3200 MT/s run at that speed on a ThinkMate VSX-R5-140V12 workstation without manual BIOS changes?

The modules are JEDEC-standard DDR4 3200 CL22 1.2 V parts, so they will operate at 3200 MT/s with CL22 timings automatically on the listed ThinkMate workstations.
