Nvidia's current-gen Blackwell family includes some of the best graphics cards on the market with exceptional performance, but pushing silicon to its limit can always unlock more power. This is where enthusiast software, such as mVolt+, comes in, allowing users to overclock their GPUs beyond what's usually permissible. Unfortunately, it seems like a new driver update has shut down mVolt+ across all RTX 50-series cards.
Unlike mainstream GPU utilities like MSI Afterburner, mVolt+ bypasses standard driver restrictions and gives you more granular control over a few hardware blocks. The app can tweak separate power targets for the core and memory channels. It can also provide access to voltage and clock offsets for Core, XBAR, SYS, and VRAM. You can manually tune the power across the interconnect and video encoders, for instance, instead of relying on a global slider.
