Star NVIDIA Pixel Clock Patcher
NVIDIA Pixel Clock Patcher modifies the NVIDIA video driver to remove the 330 MHz pixel clock limit for dual-link DVI and the 400 MHz limit for SLI and 400/500-series GPUs.

http://www.monitortests.com/nvlddmkm-patcher-1.2.6.zip

If you find this software useful, donations are welcome.

Requirements:
  • Windows Vista or later
  • 400-series GPU or newer
Compatibility:
  • Version 1.2.6 is compatible with 304.48 to 340.43. It can be used with future versions if it finds all the limits.
  • Test mode is not required anymore. Test mode can be disabled using this: testmode.zip
Getting started:
  1. Run nvlddmkm-patcher.exe. (Catleap/Tempest/QNIX/X-Star users with SLI or 400/500-series GPUs: run nvlddmkm-patcher-full.exe instead.)
  2. 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.
  3. Reboot.
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.

Known issues:
  • The full patch breaks HDCP support. It is only needed if the pixel clock is greater than 400 MHz with SLI or 400/500-series GPUs.
  • Titan and GTX 780 cards do not need the full patch for SLI.
  • 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.
Recent changes:
  • 1.2.6: Updated for 337.50. Fixed SL-DVI/HDMI limit for 64-bit. Fixed SLI limits for 32-bit.
  • 1.2.5: Updated for 334.67. Fixed SLI limit.
  • 1.2.4: Fix restore from backup for 32-bit (64-bit not affected).
  • 1.2.3: New SLI limit found.
  • 1.2.2: Removed SL-DVI/HDMI check false positive for 64-bit.
  • 1.2.1: Updated for 331.40. Fixed SLI limit.
  • 1.2: Test mode no longer required.
  • 1.1.6: Updated for 326.01. Fixed SL-DVI/HDMI limit for 64-bit. Changed SL limit on DL-DVI.

Yes, you have to stay in test mode to use a self-signed driver, but that doesn't affect anything. You can use DSEO to remove the "Test Mode" watermark from the desktop.

RE: NVIDIA Pixel Clock Patcher
It will work with future versions if the code doesn't change.

RE: NVIDIA Pixel Clock Patcher
Thank you very much! I donated because I appreciate your time and effort. It helped me make my decision to go with nvidia. I'll donate again when I get my card and monitor in a couple of weeks ,because I think 5 dollars is getting off cheap. Thank you again kind Sir!
