New undervolting companion for MSI Afterburner targets RTX 5070 through RTX 5090
NV-UV, a new undervolting companion for NVIDIA GeForce RTX 50 series graphics cards, has entered open alpha. The tool is currently aimed at GeForce RTX 5090, RTX 5080, RTX 5070 Ti, and RTX 5070 users, and it works alongside MSI Afterburner rather than replacing it. According to the project documentation, users need MSI Afterburner with voltage unlock enabled, Windows 10 or 11, and .NET 9 runtime support.
The project focuses on simplifying VF curve tuning with one-click presets such as Eco, Balanced, Performance, and Max. It also includes features like V-Lock mode, direct per-voltage tuning, automatic profile switching by game, and a built-in scanner that searches for the lowest stable voltage point. The support thread says NV-UV already includes a game database with 587 entries for its automatic UV-Pilot profile system.

The current alpha build is version 0.89 is distributed through GitHub with access details posted in the support forum. The project is still in a rough state. The documentation warns users to back up their existing MSI Afterburner profiles before testing, and it lists several known issues, including scanner behavior that is still tuned around the RTX 5090 and does not yet load smaller Blackwell cards as intended. To put it another way, only use it if you have a 5090 or if you want to provide feedback to the developer so that the tool can support other cards properly.

At this stage, it is aimed at enthusiasts who are comfortable testing stability, recovering from bad profiles, and dealing with unfinished software. But the roadmap looks interesting, developer has already listed RTX 5060 support and laptop GPU support as planned features, which means the tool may become more relevant for lower-power desktop cards and notebook variants later on.
