    Confirmed with HWMonitor, 1.16v at load, 1.06v idle with F6 bios.

    That's why i think i can adjust voltage. And if i have vddc resistor, then its not analog then, more likely its digital, then i can adjust, not?

    Can you please check what is written to the SOC's voltage regulator?

    Mine says:

    uP6213AJ
    YCF986

    Seems like voltage adjust working, i just have a crap gpu.

    Increased voltage with OC Guru v1.00. I can do 930 core on default volts.

    I increased gpu volt to 1.3 and tried 995 core, stressed with furmark fullscreen 1680x1050 post fx, displacment mapping, after few mins gpu heated up to 93 degree with full throttle fan then crashed. That was with F8 bios. I switched to bios F6 then tried again with 960 core with little volt add. No luck, added a little more... nothing, added till got to 1.3v again, but still not stable, but my temps were 20 degree higher than default volt.

    Vddc always stays the same in GPU-z, the software is unable to read these cards voltages properly. This is the same reason you can't force MSI Afterburner to work either, you need to use Gigabyte programs for voltages.

    Right click/view image if small



    OC Guru (New version for sure, unsure about old) shows real time GPU core voltage, and you can also use SOC Tuner for ALL voltages in real time (Google - Xtremesystems SOC Tuner)

    As for cross flashing the BIOS that would be up to you to attempt, if it fails you will need a PCI or another PCIE card that works so you could flash back the proper BIOS.

    I know for sure you cross-flash OC with SOC BIOS as they are the same exact PCB just a sticker over the SOC name on the PCB of the OC card, and I've flashed one myself just a week ago.

    As for the UD model I am not sure what is possible in this regard. You would need to use force flag in DOS or the Force option in windows with winflash to cross-flash.

    You shouldn't need 1.3 Vcore at all and that's probably why you can't push it very far, I use only 1.23-1.27v for 1Ghz core and 1.63-1.67 for 1300-1325 Memory on OC and SOC cards, sounds like you are overheating it by using too much voltage.

    Try less volts and I'll bet you'll have much better luck

    With higher voltage i only got 5 mhz plus on core.

    Can you check the volt reg please ? I'm nearly sure i dont have the same pcb only same heatkiller :)

    Which chip is that, on what side? Show me a pic and I can check OC and SOC PCB (Which are the same)

    Thanks, I wasn't sure and I should know since I reviewed the SOC - but sadly I had to ask :(

    This is what is on each chip, in full.

    OC PCB:

    ADP4100

    KATA923A096
    KOREA

    SOC PCB:

    THX, mine is :

    uP6213AJ
    YCF986

    So there's no chance i can apply SOC bios :(

    BTW last night i was nearly able to exchange my UD to an OC version Gigabyte 1:1. The guy's card didnt adjusted the fan between 20-70% and annoyed him, but now he wants to send it back to store and get refund and buy HD6950. I think i read about that fan problem, and could solve it. Next time :)

    Ya, you are right then. I just googled uP6213AJ and find it used on some cards and none of them allow voltage adjustments.

    So even if you could flash OC or SOC BIOS onto it, there would be no voltage adjustments.

    Sorry man!
