NVIDIA Pixel Clock Patcher

[ToastyX]

It's working for me. Did you remember to disable the extension block?

I tested all the possibilities. In fact, they removed some limits starting with 313.95. The pixel clock limits don't apply anymore when using the NVIDIA control panel to add custom resolutions, but the driver still needs to be patched to use CRU.

SLI still needs to be patched to work properly beyond 400 MHz, but the Fermi workaround isn't needed anymore. You can use the HDCP-supported patch if you don't need SLI support beyond 400 MHz.

CRU:

Dual-link DVI works past 330 MHz with the patch.
Single-link DVI and HDMI ports work past 165 MHz with the patch.
Single-link DVI on dual-link DVI ports works past 165 MHz with the patch.
Fermi GPUs work past 400 MHz with the HDCP-supported patch.
SLI needs to be patched to work properly past 400 MHz.

NVIDIA Control Panel:

Dual-link DVI works past 330 MHz even without the patch.
Single-link DVI and HDMI ports work past 165 MHz without the patch.
Single-link DVI on dual-link DVI ports needs the patch to work past 165 MHz; otherwise, it sends a dual-link signal.
Fermi GPUs work past 400 MHz even without the patch.
SLI needs to be patched to work properly past 400 MHz.
