unlocked HD3850 512mb bios

[Thoth36]

Here you go
It's from GeCube 3850 512 X-Turbo III, works fine above 860, enjoy.

Thanks Greg_1, I tried that bios, and apparently it does not lock the system above 860, but I had to reinstall the drivers (not a problem).
Now I'm gonna have to check the voltages, because it was very stable at 850Mhz (1.38v) and when I tried it above 870Mhz crysis crashed to desktop (maybe need more voltage).

Edit:
Bumped the gpu voltage (pencil mod) to 1.46v (3D), and now it's stable at 918Mhz.

Long time lurker
seldom poster, in dire need of help.
I have two sapphire 3850 512mb cards. I cannot find a bios that works for the life of me. Everything is either subsystem IDs do not match or cannot find Vbios image file. I am using ati winflash, because I have flashed my 3870 with it so many times I think the card no longer knows what it is :/

I am looking to unlock it. By the way ATI overdrive limits these cards to 720 pretty low compare to others. Anyhoot my stock bios is attached if anyone can help out.

If you own an HIS turbo 512 card and havent checked the type of vram, you'll be glad to know its Samsung. Number on the chip reads SAMSUNG 743 K4J52324QE-BJ1A. All i know about that chip is that its very close to 1.0ns by comparing it with other model numbers... havent found any info on them.

Any easy way to tell voltage on vram? Im sure default 3850 volts would be quite limited... OCing to a stable 2000mhz on default vram volts is impressive, but I cant wait for volt tweaking software!
