You need only 5 and 8, but read all of it to understand it.

Thanks a lot, will try it and give feedback 2morrow smile.gif

/// EDIT

Tried 2 times, same effect. When i flash the bios using "atiflash.exe -f -p 0 newbios.bin", it does not reboot. Everything is installed sucessfully, but it does not restart pc, so the flash is not 100% completed. What am i doing wrong...?

How am I supposed to restart my pc from dos/atiflash?

Hard restart, man... smile.gif

Just press that button, but remove the usb, or make your HDD primary bootable device... smile.gif

Sorry, i am kind of a leak, but i don't fully understand what you mean thinking.gif Press what button? By pressing power button the pc just shutdowns itself. Or how am i supposed to make HDD primary bootable device, if i am not able to access mobo bios?

How did you flash the bios? Did you use a bootable usb? If that's the case, just pull out the usb stick and then restart the pc with the restart button.

The pc won't restart automatically.

For all of you who are having "broken" (not working) HDMI (or other) connectors. This also includes "PC doesn't boot" symptoms, as long as your monitor is attached to a "no longer working port". (which you might not expect!).

So.. as far as I understand, this happens when you try to flash a "foreign" BIOS. And by "foreign BIOS" I don't mean "a bios for other model videocard", more like "any bios which is not based on your factory BIOS found on your very own board". This probably has something to do with revisions or batches or.. i don't know to be honest. Personally I found that flashing a BIOS for the "same model" videocard from the very same manufacturer and the very same sub-model (e.g. Sapphire's TOXIC card) would disable some of my card's ports. On 7950 - the HDMI, on 280X - the two mini Display Ports, I guess it varies.

So.. here's the solution. Grab your very own BIOS (extracted by GPUz for instance) and tweak it as you want, then flash it back on the card. You can use the VBE7 v0.0.4 utility (just google if you haven't heard of it) and make the changes as you want them to be. I really mean v.0.0.4, because the newer versions have a "predefined" voltages table (based on VRM type) and you'll have to select one of the predefined values, and they're limited and non-editable. With v.0.0.4 you can actually "type" the values and put whatever voltage values you want. E.g. you want 1.30v (which is unnatural for 7950 cards) - okay, just type "1300" next to "Voltage mV" and voila. You can also alter the TDP, fan profiles and stock frequencies. Once you finish - save the file and the program will autimatically "fix" the check-sums for you, so you'll be able to flash it just fine. Well, that's what the author says, but you can always use the "-f" flag on atiflash.exe to flash it anyway if needed.

This should get you rid of the "hdmi lost" problems for good.

Well, it seems then that F43 bios won't work for me smile.gif So the only way to lower the voltage is by editing the bios i have atm?

Yeap, that's what I think. wink.gif
It's really easy, so give it a try. It might solve your problems. It did for my Gigabyte 280X at least..... tongue.gif

Ok, thanks smile.gif Btw, can i just flash the bios in the windows using cmd? Since i got the bios switch on the gpu anyway, I am not risking more than using bootable usb drive, am I?
