Does anyone HAVE/HAD one of the Saphire 7500 cards. I do..by the mistake of ordering through a wholesaler. I cant overclock it or edit the bios or ANYTHING. It just wont let any tweaker proggie touch it! I have tried EVERY tweaker out there believe me! The overclocking options in the tweakers will either be grayed out, reading the Mhz WAY wrong or the sliders would be moveable but make NO difference. What an immune card. anywhoo...does any one have any secrets/coments(besides a hammer) that they might be able to share?
