Custom Resolution Utility (CRU)

[BlinkUW]

Geforce GTX 670
Crossover 34U100 (100hz native at 3440x1440)
Win 10 x64
Geforce 381.65 WHQL drivers
Connected via DP 1.2

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.

Any suggestions? Thanks!

P.S. this monitor is awesome so far. 3440x1440@101hz passes the frame skip test, as well as 2560x1080 @ 144hz
