Hi , first of all , sorry for my really bad english 
I have used your bios mod and love it from there,thank you so much^^. But 1306,5MHz of the GPU clock seem doesn't enough for me
, i would like to add some voltage to it so i can overlock the GPU more ( i'm currently run at 1442 (1306,5 + 135MHz overlock from msi afterburner with 67 to 68 degree celsius @ full load) )
=>my question is :I want to add some voltage and change the default GPU clock , could you help me known how to do this ? (do you think how much more voltage should be added to let GPU running at 1500MHz without any problem?, currently 1442MHz@1200mV is pretty stable in my case)
P/s: after many fail I have changed the gpu clock successfully but the voltage seem to be not changed, it is till keep running at 1200mV , do you have any ideas on this?
Hope you reply soon.Thank you ^^!
