You need to use the --addmode option. It's documented in the xrandr man page.

No ! Before "--addmode" I should define with "--newmode" .
Note : Read example in end of xrandr manual page .

Yes. According to your output above, you were already defining a new mode with --newmode. The next step is using --addmode, as I said.

How can fix this problem ?
My mode add to HDMI ! but i have not HDMI connection , I use VGA connection .

You
already know the answer. You use --newmode to create the mode, then --addmode to add it to the correcy output, just as it's documented in the xorg.conf file.
