Has anyone overclocked this card? If so, what was your final clock speed and memory speed? And I have warranty on this card and was just wondering will this void my warranty?
No, overclcoking your core edition card will not void the warranty. The core editions have a restricted voltage regultor, so you cant apply to much juice and break the card, so there is not need yo worry about that. I have an xfx 7770 black edition with this same feature. As for what is a decent overclcok, without the voltage boost, the most you can hope for is around 10-15%. So thats 1150 core and 1400 on the mem. Its always hard to ask for specifics aas each card overcllocks to a diferent level. Hope this helps you
