Has anyone tried to overclock the hz of this monitor and if so how did it go?

Here's a guide i found if someone wants to try it and report back.

Overclocking Quick Start Guide
AMD/ATI Video Cards

1. Use AMD/ATI Pixel Clock Patcher to patch the driver.

2. Use Custom Resolution Utility (CRU) to add higher refresh rates.

NVIDIA Video Cards


1. Use NVIDIA Pixel Clock Patcher to patch the driver (304.48 or later).

2. Use Custom Resolution Utility (CRU) or the NVIDIA control panel to add higher refresh rates.

Notes


If you use CRU, make sure "Include extension block" is not checked, and define the higher refresh rate as the first detailed resolution to make games use the higher refresh rate. Keep 2560x1440 @ 59.950 Hz as a secondary detailed resolution for driver updates, otherwise the unpatched driver won't have any resolutions to use.

If you use the NVIDIA control panel instead of CRU, you will need to install a monitor driver to make games use the higher refresh rate: catleap.zip (Install using the Device Manager -> Monitors -> Right-click "Generic PnP Monitor" -> Update Driver Software... -> Browse my computer for driver software -> Let me pick from a list of device drivers on my computer -> Have Disk... -> Browse for the .inf file -> OK -> Next -> Install this driver software anyway)

"Automatic - LCD standard" (CRU) / "CVT reduced blank" (NVIDIA CP) will allow the video card to clock down when idle. If your monitor can't handle that at 120 Hz, try "Automatic - LCD reduced" (CRU) / copy the settings below (NVIDIA CP). If that doesn't help, you will have to reduce the refresh rate.

What does overclocking a monitor actually do? Better picture or anything else? Obviously overclocking a CPU or GPU gives better performance but what are the gains of clocking a monitor?

Cru is an excellent tool, I was using it to push 120Hz over single link dvi on my old lightning :D

May try this later see if I can turn my 120Hz into 144Hz :p

Will they go any higher or are you just playing it safe? Noticed any problems or corruption?

each of mine go to a slightly different clock, so this is where I know all 3 will run fine so I don't keep having to try and remember which one will do what

I don't get any problems or corruption, I use the EVGA tool and click "set", if the monitor works then it comes back on and I see the countdown timer and I can click "ok" to keep it set... if it's too high then I just get "signal out of range" and it comes back on a few seconds later having reset itself to where it was before

none of mine will go over 90 though, they are all in the 86-89 range, so my OCD demands that I set it to the nearest 5 point for some reason

I tried pushing it to 70Hz but my DGM monitors weren't even recognised when I restarted, and I had to reinstall my graphics drivers to get everything back to normal..:confused:

Mine does this to. When i can get it working as soon as I restart my nvidia driver fails and I have to reinstall them and two of my 3 monitors arent detected. (including the dgm)
