I cant remember at the moment, i think theres an option somewhere at the top.
im not on my desktop right now, im using my laptop right now bc a relative of mine was messing with my computer and removed the heatsink from my cpu and i didnt know. and my cpu is a 2.1 triple core that i had overclocked to 2.5 so it naturally melted pretty quick.
im waiting on my new processor which should be here tomorrow. ill check for you tomorrow and repost if you dont figure it out by then.
i havent played with poweriso for a while.
