I live in South Africa, so I am not sure if ASUS would accept the card all the way back from here. Im going to speak with the local supplier where I got the card from here.
Also forgot to mention this is my second card, I had the same first one replaced like a week after I got it cause the HDMI port was dead out of the box.
No I have not as I dont have much experience messing around with it and I am afraid of breaking it
