You will definitely need to load the new board drivers. It does work. go ahead and try it, you can always do a re-install after (back up old drive or even get a new one for system and use old for second drive). I experienced trouble with mine more because I had other issues going on. Good luckCan i change my mobo without format n install a new window OS?No, Windows configures itself as per the Surrounding peripherals to give you the best performance. If you do the change without a reformat your system in most probability will crash. Back up all your files and do a reformat.
