But i never tried a bios editor. Can you edit the 9600pro bios? And is there ANY bennefit? If there is Id like this guide too.

i just saw a thread about this at guru3d forums this morning.i dont think i can link right to the thread but it is in the ati section titled bios editing.

There's not a whole lot you can do when editing a video card bios, unless you have a whole lot of experience with video bioses. Changing the default core and memory speed are fairly easy though. I'd try searching for a guide over at the www.rage3d.com forums.

If you use the latest version of radedit;

You can adjust default clock speeds and also the default refresh rate for 640, 800, 1024 resolutions. The latter is very useful since I find sometimes when i change between resolutions in windows, it'll randomly use 60hz. By setting it to 85hz, I don't get this problem.

Also, the default clock thing is equally as useful. I find that if I use a clocking utility that alters the clock on windows startup, sometimes it'll go 'badly' and all 3D apps will show hideous artifacts. But by having the card always be at an overclocked state (as done thru editing it's bios), you don't get this problem.

This thread at www.rage3d.com gives some good advice on flashing;

Get the flashrom program here;

Remember to ALWAYS make a backup of your bios with the utility, and ALWAYS make a .bat file on your boot floppy that'll automatically restore your original bios. This is very useful for doing a 'blind flash' incase the flash goes wrong.

Don't be scared though, I've flashed my 9700pro many times and it's often gone wrong. I've easily restored it though using my own made bat fix file.

anyone know compatibility issues between BBA bioses and G-byte, Sapphire or Tyan bioses? I couldn't find a BBA 9600pro bios....

All the cards are roughly the same, and use roughly the same BIOS. Some companies may tweak their BIOS for the specific ram they put on their to gain the best performance, but the worst that can happen is you get a little (as in minut) performance loss because of more lenient timings

Of course you could just extract your BIOS (which is extremely easy to do using ATi Flash which you can find at www.omegacorner.com) and edit it

i was looking in to doing that but i was hoping for a step-by-step "how to" (i am as dumb as i look)....either way, i'll be flashing and editing...thanks.

i did it...it was easy after all....i used a bootdisk i made from bootdisk.com (dos 6.22) and radedit. i started small since i leave for thailand tomorrow...bios default is now 425/324...i put on some ram sinks and when i get back, my crystal orb should be here and i'll raise the default....

You can get the same effect, by overclocking the card with rad linker in the video properties. Why mess with flashing and reflashing when you don't have to..unless you want to set it and forget it.

[Jarhead7236]

that's what i was goin' for...it wasn't hard at all....i saved my bios to disk and edited it, using radedit.

Make sure you have an untouched copy of the BIOS on hand also, just in case. You never know what might happen when flashing your BIOS.
