NVIDIA Pixel Clock Patcher
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.
After unpacking the archive, run nvlddmkm-patcher.exe and press “YES”
- Windows Vista or later
- 400-series GPU or newer
- Version 1.4.7 is compatible with 304.48 to 435.27. It can be used with future versions if it finds the limits you need.
- Run nvlddmkm-patcher.exe. (Catleap/QNIX/Tempest/X-Star users with 400/500-series GPUs: run nvlddmkm-patcher-full.exe instead.)
- If all limits are found, click “Yes” to patch and sign. If a limit is not found or if multiple matches are found, the patcher needs to be updated.
You can then add higher refresh rates using the NVIDIA Control Panel or Custom Resolution Utility (CRU).
To restore the unpatched driver, run the patcher again and click “Yes” to restore from backup.
Unpatching is not required before upgrading drivers. Simply run the patcher again after installing the new driver.
- 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.
