Can't set custom resolution

[mycomputeralias62494]

I tried using this guide here to set my resolution to 1176x664 but it didn't work.
https://wiki.ubuntu.com/X/Config/Res...ed_resolutions

I got to the point where I input
xrandr --addmode HDMI-0 1176x664_60.00

X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 18 (RRAddOutputMode)
Serial number of failed request: 29
Current serial number in output stream: 30


Edit: Oh and I am using a geforce 210 gpu

Same problem here.
Same error output.

Anyone?
