I can overclock easily to 96Hz, but as soon as I add the HDMI block in CRU it has a lot of artifacting. Underclocking the monitor below 55Hz also results in problems. Could this be an issue with my cable, or perhaps the graphics card? I have tried many combinations except for a different cable and gpu.

You can't overclock with HDMI. That monitor uses dual-link DVI, and HDMI is single-link, so it can only handle half the bandwidth. What happens below 55 Hz? That monitor should be able to handle lower refresh rates.
