Any new BIOS's for OC'rs and Abit KA7?

[madthumbs]

I have used the RY evaluation BIOS and have gone to the latest official BIOS. I found that some game features work and it's more stable. Is there a new BIOS that allows cache divisor tweaking? I would especially like one that will allow me to bring a 700/900 core up to 1GHz. There was too many problems with the RY BIOS to make it work. TIA
