mVolt+ adds advanced voltage and power controls for RTX 50 GPUs

mVolt+ is a relatively new overclocking utility that has been receiving rapid updates since launch, with the latest version adding advanced power‑channel and voltage controls for Nvidia GeForce RTX 50 series GPUs – options not currently available in tools like MSI Afterburner.

As spotted by Videocardz, mVolt+ Release v0.36 introduces separate power‑channel limits for the core and memory, alongside voltage controls across the Core, XBAR, SYS and Video domains. These additions allow certain GPUs to exceed total power limits defined in their VBIOS, enabling behaviour previously restricted to XOC BIOS or shunt‑mod configurations.

Over on Reddit, users have already begun sharing results. One RTX 5090 owner posted a 3DMark Steel Nomad run showing the card pulling close to 700W under load. Another reported core clocks between 3.15GHz and 3.20GHz, with an XBAR frequency around 2.8GHz.

Despite the expanded controls, mVolt+ cannot bypass physical hardware limits. The developer warns that extreme voltage tuning may cause instability and void warranties.

KitGuru says: While mVolt+ unlocks impressive benchmark scores, the massive increase in power draw makes it a bit too risky to run permanently.
