Safe GPU voltage

[ltnmzh]

Hi guys

I believe high voltage will damage the GPU.

I'm looking at KFA2 670 EX OC, some review say the load voltage is 1.175v. Is this safe as the card will be a permanent fixture of my machine and I want to use it for years.

Anyone happen to know the load voltage for Gigabyte 670 Windforce?

neither card will go above 1.175v without hard-modding the PCB.

In short it is (at the moment) impossible to over-volt these cards.

"The default voltage is 1.175v under load which does seem rather high, and the boost brings the GPU up to 1200 Mhz."

however the screen shot shows GPU Voltage +100

With these 600s you just shove the power target as high as you can go. That tells the card what to 'keep it's power draw under' or whatever.

The card will be fine because the software will not allow voltage over that 1.175v and the card physically cannot pull more than 1.21v (680)

Makes sense, thanks.
