GoKawiilNvidia driver update disables mVolt+ overclocking tool on RTX 50-series GPUs
Nvidia's newly released 615.56 driver blocks the core power limit adjustments that the third-party utility mVolt+ used to push RTX 50-series GPUs well past their rated power limits. Users report the screen goes black, mimicking a driver crash, whenever the tool tries to apply extra current, regardless of the settings used. The app had previously let enthusiasts drive cards like the RTX 5090 to 650-700W and an Asus ROG Astra RTX 5080 to 680W without VBIOS swaps or hardware mods.
GoKawiil's interpretation of the reporting above, not reported fact.
mVolt+ offered a rare software-only route to extreme overclocking that normally requires custom BIOS flashes or physical PCB modifications, making high-power tuning accessible to a wider group of enthusiasts. By closing this loophole, Nvidia reasserts control over how much power its GPUs can draw, likely to limit warranty and safety risks tied to unofficial overvolting. The move also signals that Nvidia actively monitors and patches driver-level exploits used by overclocking communities.
- Nvidia's 615.56 driver disables mVolt+'s core power limit overrides on RTX 50-series cards.
- mVolt+ previously enabled power draws up to 700W without hardware modifications.
- The update shows Nvidia is closing software loopholes that bypass official power limits.
