overclocking intel igpu *Read disclamer*

[dtuchhypercraft]

before complaining about this
1 im doing this with no expectations at all so anything is something
2 the laptops thermal solution allows for this (70c max underload)what
3 i know it laptops and igpu shouldnt be overclocked)
so ok
i downloaded intel extreme tuning utility
and managed to get a 14x multiplier on the gpu with 175 processor graphcs voltage offset
my qeustion is
what would the max processor graphics voltage be under safe operations? default is 0.500
and is putting the voltage offset to high dangerous?
its a intel hd 4400 running on a thinkpad s540 (sadly no gpu option so stuck with intel hd)






also the laptop has some defect keyboard keys ( the 8 i k and , key) they sometimes work and sometimes dont so ik spelling might be slightly off

Can't help with the graphics but if you remove the keyboard and re seat the ribbon cable that should fix the keyboard.

tried that doesnt help the keys work if you hold them for a couple of seconds (the entire row starts working for 2/3 mins) like right now
