NVIDIA Pixel Clock Patcher modifies the NVIDIA video driver to allow higher resolutions and refresh rates by removing the 165 MHz pixel clock limit for single-link DVI and HDMI, the 330 MHz limit for dual-link DVI, and the 400 MHz limit for SLI and 400/500-series GPUs.
Compatibility NVIDIA Pixel Clock Patcher
- Version 1.4.8 is compatible with 304.48 to 442.50. It can be used with future versions if it finds the limits you need.
Known issues NVIDIA Pixel Clock Patcher
- The full patch breaks HDCP support. It is only needed if the pixel clock is greater than 400 MHz with 400/500-series GPUs or SLI with 600/700-series GPUs until 391.35.
- NVIDIA cards will not reduce clock speeds when idle if the vertical blanking/total is too low.
- 400/500-series cards will not reduce clock speeds if the pixel clock is greater than 404 MHz.
