I have a Diamond HD3850 512MB card, and I want to mod the BIOS to 1.33 volts, and if at all possible remove the 850MHz overclocking limit. Can anyone help me with this? Thanks

Ok, I have that exact same memory. I just flashed this Sapphire 3850 512MB BIOS to my card, and it worked. I'm currently having someone voltmod it, but Sapphire removed the overclocking limit on it. I searched to see if anyone had modded the native Diamond HD3850 BIOS yet, but no one has. Heres that Sapphire BIOS, http://www.ocforums.com/attach...tid=62162&d=1200859553

I found a modded version with 3870 voltages.

Yep thats the one I tried. However that HIS one here looks tasty, I'll give it a spin and see if it works with our Diamond cards.

Have a link to it? I found one too that was a Sapphire, but it didn't work when I flashed it, it simply came up with a blackscreen afterwards.
If it blackscreened, how did you "unflash" it?

It's been a while, but If i remember right.
The pc will still post,so you can blind flash it.
Boot into dos and type away,
or
You can put in a pci video card and use it's output so you can see what your doing.
I am however, more than happy to let Ghost recon88 live up to his screen name ,and check it out before I try it![]()

I don't know about the blind method, but I do recall the above method. I've done some crazy motherboard flashes (boot up system, remove bios after booted, insert screwed up bios chip from another system and flash, shut down) but not a video card.
