16 GB DDR4-3200 dual-channel kit with CL22 timing and 1.2 V operation for Thinkmate VSX-R5 workstations
This 16 GB kit contains two 8 GB DDR4 UDIMM modules built for Thinkmate VSX-R5 workstations. It targets administrators and technicians who need a straightforward capacity increase without changing the platform. The modules are validated for the listed VSX-R5 variants and install in standard 288-pin slots.
Each module runs at 1.20 V with CL22 timings at 3200 MT/s, matching the JEDEC DDR4 baseline for unbuffered memory. No heat spreader is fitted, so airflow from existing chassis fans passes directly over the DRAM. Power draw stays within normal DDR4 limits for this density and speed.
The 2 x 8 GB configuration populates a pair of slots for dual-channel bandwidth while leaving remaining DIMM positions free for future expansion. No buffered or ECC circuitry is present, so the kit suits non-ECC consumer and workstation boards that accept unbuffered UDIMMs. Verify the motherboard manual for maximum supported capacity per slot.

Power off the system, open the chassis, align each module's notch with the slot key, press firmly until both side clips click, then verify the full 16GB appears in BIOS — the step often missed is seating both ends evenly so the clips engage.
No scheduled maintenance is required; keep interior dust-free for airflow. Replacement is only needed if a module fails — the lifetime replacement warranty covers that event.
The CL22 latency at 3200 MT/s sets the throughput ceiling; thermals stay modest at 1.2V without a heat spreader, so latency-bound performance is the first bottleneck.
