Sorry I'm a bit shocked right now. Now I've killed 2 780 ti matrix cards in 1.5 weeks for no reason and now I would have to rma even the board aswell, life pisses on me lol. Last night while watching on youtube the whole system just shutdown, everything was at stock and the xcb board for matrix was disabled. I tested psu and it works and pc runs fine with another card but that one. I tried powering the system with the card inplace but without pci-e cables and slot disabled I heard a small clear electrical shock sound like zap, but system kept posting like normally. The rig wont even power on now with that specific card in slot lol, it like grounds the whole rig and nothing happens when you press start button.

Why did I buy the matrix cards lol, nothing but problems. Something must be shorted in the graphics cards power delivery, zzolio on kingpin forums told me to measure pci-e connectors and the left one has 3 pins that don't beep or give resistance value at all, where as on the other connector they do fine. Other pins are identical. I really don't know what it is.

Sorry for writing all this, but I have never RMA'd anything in my life before lol and now in 2 weeks I should rma 3 quite expensive products lol, 2 matrix 780 ti cards and one z97 board. And both cards were amazing samples, both did around 1450 on the core with nvidia locked voltage of 1.21v, other one did more. see here: http://www.youtube.com/watch?v=rji3G-11MAs

Not the best day of my life...
