you are very welcome to ask anything. i enjoy answering your questions.
yes you can easily overclock it. i will recommend using MSI afterburniner. just google it.
i dont suppose that you have any overclocking experience. if thats the case i will not recommend just starting to try it without knowing what you are doing.
there are alot of videos on youtube that explanes how it works.
one of them is this one:
he is talking about extra fans and switching the stock cooler, but you dont have to do that, it helps for higher overclock but i dont recommend messing too much around with it considering that you are not an enthusiast.
he might also talk about setting the fan speed manual, but i dont do that. i want it on auto so that the card is not loud when i am surfing the web.
(on auto it will adjust it self after the need, but most of them dont go higher then 80% and thats why some will controlle the fan manually, but i just cant stand the noise. going over 80% is loud as f*ck)
