My experience with unlocking and reblowing the BIOS on the 9700 non-Pro is that I went back to the original BIOS quickly! The OC problem you'll always have is that you can't overclock the inferior Infineon or Hynix BGA RAM that comes on all non-Pro 9700's. You can make the card "think" it's a 9800 or whatever, but 3.3ns RAM cannot be confused into "thinking" that it's 2.8ns RAM.
I'd suggest you go back to the original BIOS (if you can) and use Rage3D Tweak to OC the core. You should be able to do that easily. But forget about the memory, guys, it's a lost cause. My default memory clock is 297 MHz (which is actually pretty good), but I can't OC it to more than 305 MHz before it craps out and I have to reboot.
I've watched lots of people, including me, fight this battle for nearly a year now. You won't win. Next time I'm sure we'll all buy the Pro model of whatever is offered. But I'll tell you this: for the money I'll say that a Powercolor Evil Commando II 9700 non-Pro was and remains an excellent buy.
