Default Flashing Sapphire 5850 bios

Hello hardwarecanucks. Currently I have two sapphire 5850 in crossfire, I wouldn't mind over clocking both a wee bit and do some benchmarks. I've read that you can flash these cards with Asus bios for increased overclockability. I was wondering if any of you out there have done this and if so what's your experience with it?

Well,
I've never done it, but I know that this site has the needed BIOS files:

techPowerUp! :: Video Bios Collection

It's weird that ASUS BIOSes are meant to allow more control over the VOLTERRA VRMs and no other manufacturer issued BIOS updates doing the same thing.

Hey an easier way to overclock higher is:

1. Download MSI Afterburner

2. Go into the program location

3. click the .cfg file and open with notepad

4. change the unofficialoverclocking to 1 instead of 0

5. open after burner and enjoy!

there crashing because your video card can't go that high Lol.

lower the settings, go up 10 mhz at a time while running kombustor.

Like he said, start overclocking from stock speeds and slowly push it up. I prefer using the FurMark or OCCT GPU Stress test though. Then a couple loops of 3DMark while I'm afk to test for stability.
