I don't see why you couldn't. The Asus utility is for Asus cards, it says it won't support SE or LE models but yours is XT. It should work if it's an Asus, but may I make a suggestion. Why OC an ald 2004 card while their are modern ones which could suit sour needs? The 9600 is obsolete.
I'm having problems with the fan on my card so I just wanted to get some readings and make sure it is not overheating will be buying a new computer soon so I don't want to put any money into this one if I don't need to thanks for your response
