Use Sapphire Trixx to modify the VDDC.

Thanks for reply.
I bought the card, tried it in Asus p5vd2-mx se motherboard (which has PCIeX16 slot) and it did not boot. I was not sure if it motherboard or videocard problem, sent videocard back.
Bought GIGABYTE GV-R785OC-1GD Radeon HD 7850 1GB card, but it did not boot either. Than I realized I need a new motherboard (yes, motherboard had BIOS updated). I bought ASRock E35LM1 AMD E-240 APU AMD A50M Mini ITX Motherboard/CPU Combo and now it is running fine. The only thing is it looks like card voltage is locked and I can not underclock it with Trixx. Card came clocked to 900MhZ and it works nicely on 1000MhZ and I do not want to push it more. I would like to underclock it if there was a way to do it without losing the warranty. Otherwise card works cool enough (70C) and quiet with fans running around 40-44%.
