A new community-driven utility, NV-UV, promises to offer Nvidia RTX 50-series owners a more streamlined way to manage the power and thermal characteristics of their “Blackwell” hardware.
Developed by cubi2k82, NV-UV (via PCGH and VideoCardz), which is still in closed alpha, is designed to work as a companion app for MSI Afterburner rather than a standalone replacement. It arrives as a direct response to changes in Nvidia's NVAPI, which reportedly no longer allows for the same direct write access to the Voltage-Frequency (VF) curve that enthusiasts enjoyed with previous generations.
The tool aims to make manual undervolting more accessible by automating and providing presets. Initially, it features a one-click interface with four primary profiles: Eco, Balanced, Performance, and Max. These presets allow users to quickly switch between efficiency-focused settings and raw performance targets without manually plotting points in a curve editor.
Perhaps the most innovative feature is the UV-Pilot mode, which reportedly uses a database of over 570 titles to detect supported games and automatically apply matching undervolt profiles. For those who prefer a more hands-on approach, the utility includes an Auto-UV scanner equipped with its own DX12 and DXR (Ray Tracing) stress tests, live telemetry, and a specialised crash recovery system that can automatically downclock the GPU following a driver failure.
As for compatibility, NV-UV currently supports the RTX 5090, RTX 5080, RTX 5070 Ti, and RTX 5070. To use the utility, the developer recommends NVIDIA 590-series drivers or newer, a Windows 11 64-bit environment, and a fully updated copy of MSI Afterburner with voltage control enabled. The tool is distributed as a portable executable, meaning it requires no formal installation or separate .NET framework to run.
KitGuru says: As the tool is still in alpha, you should proceed with caution. If you have little experience tinkering with overclocking and voltage curves, you may be better off waiting for a more stable version of the app.
