The reason I ask is I couldn't get my 100HZ refresh rate to show on CRU until I ran the pixel clock patch for my GTX 970. I actually got it to show 75HZ, but for some reason would not show 100HZ until I ran this patch.

That depends on the limit. The patch is needed for the 330 MHz dual-link DVI limit when using CRU but not when using the NVIDIA control panel. The 165 MHz single-link limit on dual-link DVI ports affects both, but that's mostly useful for 1080p monitors.

HDMI does not need the patch if HDMI support is defined in the extension block. Otherwise, HDMI will act like single-link DVI, which requires the patch for the 165 MHz limit when using CRU.
