can this be overclocking or not ???
its not the black Edition one 2
That will depend on your motherboard. but it's capable.
*Gigabyte - GA-MA785GM-Us2H - with Bios F11
*Readon Ati 5770 HD 1GB GDDR5
and if it can be done will it be faster ????
I'm pretty sure that motherboard supports overclocking.
how can it be done is there some special way u can tell me about ?
You have a lot of reading to do. For an easier overclock I'd try a little program called EasyTune and take baby steps with it. It's made by Gigabyte for their motherboards.
