mVolt+ version 0.36 exposes hidden Blackwell power controls, letting overclockers push the RTX 5090 to 700W and RTX 5080 to 680W without shunt modding. The new Core Power Limit bypasses VBIOS restrictions, enabling power draws far above NVIDIA's rated 575W TDP. Enthusiasts report gains of up to 50W on the RTX 5090, while lower-tier cards like the RTX 5060 Ti see only marginal increases.

Key Facts

mVolt+ v0.36 exposes Core and Memory channel power limits, GPU clock ranges, and voltage-demand offsets for Core, XBAR, SYS, and Video domains.
Reddit user u/SyncFail_ pushed an RTX 5090 to 700W, nearly 50% above the rated TDP, while another user reached 700W at 3.2 GHz core and 2.8 GHz XBAR clock.
An ASUS ROG Astral RTX 5080 was pushed to 680W, exceeding the official ASUS BIOS limit of 450W TGP.
An RTX 5060 Ti gained only 20W from the new Core Power Limit, showing results vary by GPU model.
The new Core Power Limit increases total power draw beyond the VBIOS-set limit, adding about 50W on the RTX 5090.

Hidden Power Controls

mVolt+ v0.36 exposes low-level controls for NVIDIA GeForce RTX 50 series GPUs, including Core and Memory channel power limits, GPU clock ranges, and voltage-demand offsets for the Core, XBAR, SYS, and Video domains. Unlike conventional overclocking utilities that only raise the power-limit slider, mVolt+ exposes an internal power constraint called the Core Power Limit. Once this restriction is raised, GPUs can continue drawing power beyond the limit imposed by their VBIOS until another constraint becomes the bottleneck. The tool has become a favorite among enthusiasts for pushing RTX 50 series cards beyond limits impossible with conventional tools.

Overclocking Results

Reddit user u/SyncFail_ pushed an NVIDIA RTX 5090 to 700W with mVolt+ v0.36, nearly 50% above the rated TDP. Another user reached 700W as well, running the GPU at around 3.2 GHz with a 2.8 GHz XBAR clock, improving on a previous best of 3.0 GHz with MSI Afterburner. Some enthusiasts report reaching 600-650W on the RTX 5090, still remarkable given the default limit of 450W. An ASUS ROG Astral RTX 5080 was pushed to 680W, exceeding the official ASUS BIOS tool limit of 450W TGP for that edition. An RTX 5060 Ti reportedly gained only 20W from the new Core Power Limit, indicating results vary considerably between GPUs.
