NV-UV now supports RTX 40 series experimentally
NV-UV, the undervolting companion tool built around MSI Afterburner (yes, you still need to install it), has received a new v0.93 release called Cantor. We covered the project on as a GeForce RTX 50 undervolting utility, then again when it entered open alpha. The latest release shifts attention to Ada, with the developer now listing experimental support for GeForce RTX 40 series cards alongside existing RTX 50 support.
Cantor v0.93 supports RTX 5070, RTX 5070 Ti, RTX 5080, RTX 5090, and RTX 5060 Ti, while RTX 40 series support is marked as experimental. The developer says Ada preset tables are community-sourced and still need hardware verification, so this is still an early support phase rather than a fully validated rollout. The same release also adds preset tables for RTX 5060 Ti.
The new NVAPI Direct Mode writes directly to the NVIDIA driver during active scans instead of routing every step through Afterburner. The developer says per-point measurements that previously took 3 to 5 seconds now complete in around 50 ms. MSI Afterburner still handles final profile storage, overclocking controls, OSD, and fan settings.
NV-UV for enthusiasts
NV-UV is still not a replacement for MSI Afterburner. The project is a companion tool for undervolting, with features such as preset-based tuning, scan automation, game-specific profiles, and crash recovery. To use the tool, you need a password to download the tool, which requires you to ask for an invitation on Discord/PCGH forums. (Don’t tell anyone, but you can find the password in the Reddit post down below).
For RTX 40 owners, this is the first release that formally adds Ada support to NV-UV, even if it still needs wider tester validation. For RTX 50 users, the bigger change may be the faster scan path and added RTX 5060 Ti presets.
