This will work 100% guarenteed on my Sapphire 4850? I don't really feel like bricking it

Does it matter that I changed the heatsink, and that theres nothing plugged into the fan header? (DuOrb uses molex)

@HUGE DINK: I have modded the voltage for the hard OC 4850 BIOS so it will work perfectly man.

@SLINGKEY: Im sure that if you flash you bios to the Hard OC version I am sure you will be able to go up to 845/1100. 100% man!!

Good to know temps dont rise much with the extra volts... What cards were these BIOS taken from and do we know the compatability with other manufacturers cards.

Back in the day of the 9800 Pro and XT we had problems with some because they used different RAM, some Hynix some unbranded etc etc... Is this a problem we may face with these cards.
