NV-UV
GPU Undervolt Companion Tool for NVIDIA RTX 50-Series (Blackwell)
NV-UV simplifies GPU undervolting by working alongside MSI Afterburner. One-click presets, automatic game detection, crash recovery, and a built-in DX12+DXR stress test scanner.
NV-UV is a companion tool, not a replacement for Afterburner. For overclocking, OSD, fan control and advanced curve editing, Afterburner remains the tool of choice.

Requirements
NVIDIA RTX 5090, 5080, 5070 Ti, or 5070
MSI Afterburner 4.6.6+ with RTSS
Windows 11 (64-bit)
Latest NVIDIA driver
Features
Voltage Lock — one click, GPU runs at an exact voltage/frequency point
4 Presets — Eco, Balanced, Performance, Max (community-validated per GPU)
OCS → UV Import — import AB OC Scanner results, build a chip-specific UV curve
Voltage Step Scanner — DX12+DXR stress engine with FMA math-error detection
Game Replay — automatic frequency step-down on crash, with per-game learning loop
UV-Pilot — detects 587 games, automatically switches to the optimal UV preset
Smart Hz — desktop 60Hz, gaming native Hz (experimental)
Mini View, DE/EN, System Tray, 3 Skins
How It Works
NV-UV reads and writes MSI Afterburner profile files to apply voltage/frequency curves.
Live telemetry via MAHM Shared Memory and NVML.
v0.92 Hotfix (27.03.2026)
Fixes:
WPF rendering optimized, the main window caused measurable GPU performance loss during benchmarks. For maximum scores use Mini View or minimize NV-UV to tray, your UV profile stays active in AB.
Log fix: Stock curve showed wrong value after wizard, internally everything was correct.
Version number in footer corrected (v0.92 instead of v0.36).
New features:
Auto-Mini on Gaming, Right-click UV-Pilot → "Mini View on Gaming". Auto-switches to Mini View when a game is detected, returns to full view on exit. Disabled by default.
3DMark in game database , recognized by UV-Pilot, no UV tier assigned. Your active profile stays as-is, a custom profile can optionally be assigned via the Game Browser.
Other:
Guides (DE + EN) updated: performance tip, Auto-Mini, 3DMark, RTX 40 "being explored"
Game DB: 588 games + benchmarks
