16 GB DDR5 UDIMM for Thinkmate VSX-R5-340V12

This 16 GB DDR5 4800 module is built for the Thinkmate VSX-R5-340V12 workstation. It uses a 288-pin unbuffered UDIMM form factor with 1Rx8 organisation. The stick runs at 1.10 V and carries a CL40 latency rating.

Capacity and headroom

A single 16 GB rank adds meaningful space for multi-threaded workloads and virtual machines. The 4800 MT/s data rate handles typical server tasks, but heavy in-memory databases or large render queues will exhaust the single module before the platform reaches its maximum slot count.

CL40 latency at 1.10 V

The decisive spec is CL40 at 1.10 V, which determines whether the memory controller can train without manual timing changes. If your board requires tighter latencies or a different voltage, this module will not post.

Questions about this item

Will this DDR5 4800 module run in my THINKMATE VSX-R5-340V12 alongside existing DDR5 sticks?

Yes — it is a 288-pin DDR5 UDIMM rated at 4800 MT/s, 1.10 V, CL40, 1Rx8, non-ECC and unbuffered, matching the workstation's native memory specification.

How can I verify the module is operating at 4800 MT/s with CL40 timings after installation?

Open the BIOS or a tool such as CPU-Z and confirm the memory frequency reads 4800 MT/s (PC5-38400) with CAS latency 40 at 1.10 V.

What exactly ships in the package and is anything else required to install it?

The box contains one 16 GB DDR5 4800 UDIMM (part MD38400-618K1); no heat spreader, cables or extra brackets are included or needed.
