[Question/Request] Z87X UD3H Intel HD RAM allocation and Fan pwm control

Hey guys, i have a question and in case if its possible, a request that im willing to donate.
Currently im using a Z87X UD3H board with a custom Bios. The bios has a limit to the maximum intel HD graphics RAM allocation. Is it possible to mod this value to increase it?
Also, on the Fan speed configuration, is it possible to mod the values of the PWM speed?
If you need more information or screenshots, let me know

Thanks for the info.

Pepeo.
