Trying to overclock this monitor using CRU, but the resolutions aren't showing up after I hit ok. They store within CRU, but I don't see them within Nvidia's "Change resolution" or in Window's display settings.

The only one that seems to stick is 101hz. That one shows up, any choice higher doesn't show up. Used pixel clock patcher since I'm on a Fermi card, not sure if that was necessary but no change. Also tried reinstalling Geforce Experience without luck.

GTX 670 is Kepler, not Fermi. Kepler is limited to 540 MHz pixel clock with DisplayPort. The patch does not get around DisplayPort limits. You might be able to squeeze in a few more Hz by reducing the totals, but not by much at that resolution. "LCD reduced" might give you 104-106 Hz if the monitor can handle lower totals.
