    I also feel that its worth noting that my first card is plugged directly into my PSU using the PCI-E connections, however the second card is plugged in using the PCI-E chords it came with which has the PCI-E connection on one end, and a molex connection on the other.... my PSU is modular and if i had more of the same cords i used for the first i woulda done that with the second, but i didnt know if it mattered or not.

    i think that vcore voltage of 1.519 is set too high causing your system to overheat well playing games.
    what do your temps look like ?

    Voltage 0.875V - 1.5V
    yours is set to 1.519 thats why i'm saying it's set to high.
    the max should be 1.5v.

    ok cool thats good information to know then lol. for my future knowledge, think you can kinda elaborate on how high voltage like that can cause it to overheat or freeze up etc?

    the higher the voltage the more heat it makes. i'd turn it down to maybe 1.24v and see what happens. also putting to much voltage to the cpu can damage it. ( not saying it will just that it can).

    this site may help you out a little more with voltage settings and heat.

    Great link, learned a lot Im going to put all back on stock for now.... question though, what if in bios the voltage is on auto, if it is why would it put my volts so high, and should I just lock it at something like 3.5 etc.

    ok.. i tried bumping the voltage down to 1.375 and i could only play a game for about 10mins before massive freezing... im totally stumped here... before with 1 card and the voltage at 1.5v and OC to 3.6ghz i was having 0 issues, but add another card and all of a sudden im crash central.. no idea what to do now.
