Hi.
As I see, there is a possibility to raise Overdrive limits in BIOS. Why do you modifying old BIOSes (1.0003)? Please, raise up limits to 800/1300 in new 1.0004 BIOS from PowerColor/Sapphire and release it with checksum fixed if that's possible. Please don't change anything else (including fan settings) - only limits. I need this BIOS in this form. Thanks in advance.
Regards,
sarmat.

And I don't change anything else!
Good luck! ;)

any chance of modding the bios Power Color and making it so 3d clocks = 1.2v 700/1000
have you tried using powerplay settings 160/500 in 2d? or is that a bit complicated
cheers :welcome:
All of these bioses say invalid bios image when I try to flash with atiflash?Quote:

leonarderman are you sure you got the checksums right?
It works for me on vista 64, are you using XP, because if you are you have to change the file extension so it shows up as a rom file and not a bin file.
I was able to flash his bios' no problem, but the one problem I have run into so far is that if I try to install the CAT 8.8 betas it won't recognize my card as a valid ATI card. The CAT 8.7's work fine though and didn't give me a problem. Which is why I'd like to have my own card's bios modded just slightly without messing with the checksums.
Have you tried atiflash from dos with -p -f 0 [bios.bin]?Quote:

Cool, good that that worked out. Hope you don't run into the driver issues like I have.
Same issue with catalyst 8.8 beta in my XP install....the catalyst 8.7 on my Vista worked fine :(
Its like a similar issue with 8.7 beta where modded bios didn't work...any ideas guys?
Well I tried both the asus and the powercolor but neither one are working with my cards. After I reboot I get no signal from either card with these bios. Had to go back to my original, the saphire one's work but I couldn't change any of the overdrive settings for some reason. Anybody else having this problem?
Edit: I've got a Diamond and a Powercolor
hello.
when i flash my gigabyte card with the powercolor bios, it sais that doesn't recognizes it. :confused:

Try to Done! :rolleyes:
can you do this with the vmod applied? my card needs more than the default voltage to get 700Mhz stable :pQuote:

But I think the card HD4850 is easy stable at core 700Mhz with vcore df. With my Sapphire HD4850, I can overclock core to 750Mhz stable easily! Try again or mod Vcore by Pencil to get more result! ;)
now im confused :p Does it bios come with the soft-vmod applied (to get around 1.2v underload) or not? the default voltage for the HD4850 is around 1.13v underload :)Quote:
