Compatible DDR5 Upgrade for Thinkmate VSX-R5-340V12

This NEMIX RAM module delivers 8 GB of DDR5 memory at 4800 MT/s with CL40 latency and 1.1 V operation. The 288-pin UDIMM is built with major OEM chips and tested for the Thinkmate VSX-R5-340V12 workstation. It is a non-ECC, unbuffered single-rank stick designed for straightforward installation.

Replaces Slower or Smaller Factory Memory

The module upgrades systems originally equipped with lower-capacity or slower DDR5 DIMMs. The jump is worthwhile when the workstation handles larger datasets, virtual machines or multi-threaded workloads that exceed the original memory ceiling. No heat spreader is fitted, so clearance inside dense chassis remains unchanged.

Suits IT Teams Maintaining Qualified Thinkmate

Buyers who need guaranteed compatibility with the specified Thinkmate model will find this part validated for that platform. Builders requiring ECC error correction, registered buffering, higher frequencies or larger single-module capacities should look elsewhere. The single 8 GB stick also limits total capacity on boards with few slots.

Questions about this item

Will this 288‑pin DDR5 UDIMM fit the memory slots in my THINKMATE VSX‑R5‑340V12 workstation?

Yes, the module uses the standard 288‑pin DDR5 UDIMM form factor that the VSX‑R5‑340V12 expects, so it seats directly into the board’s DIMM slots.

What is the correct way to seat this single‑rank 1Rx8 module, and what step do builders often miss?

Align the notch with the slot key, press firmly until both side latches click, then verify in BIOS that the 4800 MT/s speed and CL40 latency are detected.

Does this non‑ECC unbuffered stick need any firmware updates or periodic replacement?

No firmware is required; the module runs at 1.10 V with major‑OEM DRAM chips and is covered by a lifetime replacement warranty if a fault ever appears.
