System-Specific DDR5 Kit

This NEMIX RAM kit delivers 128GB of DDR5 memory across four 32GB modules. It is validated for the THINKMATE VSX-R5-340V12 workstation. The kit targets IT professionals and builders upgrading that specific platform. Buyers needing registered ECC memory or a different form factor should look elsewhere.

DDR5 4800 CL40 Specification

The modules run at DDR5 4800 (PC5-38400) with a CAS latency of CL40 at 1.10V. They are 2Rx8 unbuffered non-ECC UDIMMs built with major OEM DRAM chips. This exact speed, voltage and latency combination determines whether the workstation will accept the kit without configuration changes.

288-Pin UDIMM Integration

Each 288-pin UDIMM installs directly into the workstation's desktop memory slots without a heat spreader. The four-module kit populates all channels for maximum bandwidth on the supported platform. It requires a motherboard that accepts non-ECC unbuffered DDR5 at this density and rank configuration.

Questions about this item

What does the 4800 MT/s speed mean once the kit is installed in the ThinkMate VSX-R5-340V12?

The modules run at DDR5 4800 (PC5 38400) with CL40 latency at 1.10 V, delivering the rated throughput as long as the workstation's memory controller supports that speed.

How does the 288-pin DDR5 UDIMM interface limit what the kit can do in practice?

As non-ECC unbuffered UDIMMs, the 2Rx8 modules rely on the motherboard's memory controller for error handling and signal integrity, so maximum capacity and stability are bound by the platform's UDIMM specifications.

What physical space and power do the four 32 GB sticks need to fit the workstation?

Each stick is a standard 288-pin DDR5 UDIMM without a heat spreader, operating at 1.10 V, so they occupy four adjacent DIMM slots and draw minimal power within the chassis.
