    See title. Is it at all possible? I did it with my D900F's 5870M, so I know my way around a little bit... Just want to know if there are any concerns.

    Thanks.

    Bios is integrated into the system bios so it's very difficult.

    The new MSI afterburner preserves powerplay when overclocking however so I would just stick to that.

    Damn. I just hate having a program open in the background all the time. Makes me crazy.

    But good to know. That means that with Afterburner, I basically just set the 3d mode level, and it'll still clock down when not in use? Being able to set each step along with overvolting were my main objectives via vBIOS overclocking.

    PhoenixTool works just fine with both Phoenix and Insyde BIOS. Insyde BIOS is a bit different from Phoenix, so the instructions above will probably not work. You will need to find the proper vBIOS file manually. You can use a GPUz tool to find your vBIOS version and then simply search for it in the extracted files (using hex editor?). Once you find it, then you just edit that file with ATI vBIOS tool. I think that is how it is done. I have never done this myself, so I am not even sure if that would work.

    As for the modded BIOS I posted, I do not have 4820TG, but I am 100% sure there is no simple video overclock menu in the BIOS setup. You have to manually edit vBIOS to change to the clocks that you want.

    I hope this helps.

    Nah, I was asking if the modded BIOS had 'User modified modules' enabled, from anything you'd read while discovering it.

    Didn't aylafan try out the freshly baked unlocked Insyder BIOS image for the 4/5820TG (same BIOS) in the other thread? Or is there a separate BIOS for the actual GPU module.

    There's the Insyde BIOS, and the Radeon VBIOS. Two different things, but linked together in this case.
