HD 5870 BIOS Flashing to OC past 900/1300

Anubis_386 · Oct 5, 2010

I'd like to flash the BIOS on my PowerColour HD5870 1GB with an unlocked version so I can overclock it past the 900/1300 max that CCC/Afterburner enforce.. Like in this guide..

However the Asus unlocked BIOS file is no longer on RapidShare and the link to a program for creating a bootable DOS disc is also dead..

Can anyone help?.. Cheeers! :beer:

you can flash your own bios if you want

i have never done it and never will, but you might want to at least see that.

I know how to edit and re-flash my bios but would prefer to overclock the card past 900/1300 through Windows so I don't turn it into an expensive paper weight..

is the gain really worth the risk?

With an unlocked bios, fair cooling and some more voltage most 5870 cores can hit over 1GHz .. The VRAM on my card doesn't clock too well tho which is a bit annoying

I was using MSI bios to unlock 5850 and I bet that most MSI bioses from reference cards will work for you the same as this asus one.

Have you tried going into MSIAfterburner.cfg and changing "EnableUnofficialOverclocking = 0" to "EnableUnofficialOverclocking = 1"?
