ThinkMate VSX-R5-340V12 DDR5 memory kit

This 64 GB kit contains two 32 GB UDIMMs built for the ThinkMate VSX-R5-340V12 workstation. It targets IT professionals and enthusiasts who need a validated DDR5 upgrade for that specific platform. The modules are non-ECC and unbuffered, matching the motherboard requirements exactly.

Rigorously stress-tested modules

Every stick is stress tested under load before shipping to ensure stability in mission-critical environments. The kit arrives as a matched pair with no extra cables, software or heat spreaders included. Installation follows the workstation manual and typically takes only a few minutes.

DDR5 4800 CL40 2Rx8 at 1.1 V

The decisive specification is the DDR5 4800 speed with CL40 latency, dual-rank 2Rx8 organisation and 1.1 V operating voltage on 288-pin UDIMMs. Systems requiring ECC, registered DIMMs, a different data rate or another pin count cannot use this kit.

Questions about this item

Will the 2Rx8 dual-rank layout on each 32 GB module require any future firmware or BIOS updates to stay stable?

The kit runs at the standard DDR5 4800 speed with CL40 timings at 1.10 V; no special firmware or BIOS steps are mentioned for the dual-rank 2Rx8 organisation.

What is the first limit reached when the memory runs continuously at DDR5 4800?

The modules operate at the JEDEC DDR5 4800 (PC5-38400) data rate with CL40 latency; sustained workloads will hit that rated speed and timing ceiling first.

How much heat and power do the two 32 GB sticks produce when the workstation runs all day?

Each module draws 1.1 V with no heat spreader fitted, so total power scales with the 64 GB capacity at the standard DDR5 4800 voltage.
