2nd SLI card to break in 2 months!

I'm currently running 2 gtx 760's in SLI and as I was playing Crysis 3, the game crashed. I reloaded the game and I had a terrible flickering going down my screen. I disabled SLI and the flickering went away.

2 months ago I had 2 gtx 680's in SLI and I had a very similar experience but in Battlefield 3, I figured it was just a defective card and I returned it.

Now I'm thinking there's something wrong with my system that's breaking my video cards. Any of you know what it could be?

I had a couple crashes recently while gaming causing me to hard reboot. I figured it was the nvidia beta driver so I went back to the last driver today-and shortly after my bottom sli card broke.

note: the original SLI bridge that came with my mobo ended up breaking (It worked perfectly fine until I got my gtx 760's so I swaped it out and the SLI worked fine). I also had both of the video cards overclocked (+50 on the core and +500 on the memory). Temperatures are fine, nothing exceeds 70c.

My system specs are:

corsair tx750 wat psu
asrock z77 extreme 4 mobo
2 gigabyt gtx 760's in SLI
1 1tb hdd
1 120gb ssd
dvd/cd drive
intel 3570k i5 clocked at 4.5ghz

When you overclocked your CPU, did you make sure the PCI buss stayed locked to 100MHz?

The flickering seemed to have gone away now, but I would still like to know what could be causing it.

Could my overclock break the card?

Some cards don't like PCI buss clocks over 100MHz. If you bumped your BCLK, set it back down to 100MHz, even if it takes a little off your OC.

I havn't touched my BCLK, it's still set to 100 MHz.

the issue came back! From what I can see it's only happening in Crysis 3 and it's black parallel bars going up and down on my screen.

I'd like to know if anybody has come across an issue like this before. I'm going to keep experimenting with my system. It seems like the bottom card is defective after a week of use, but again... This is the second time this has happened and I don't want to replace the card to see this happen again in the future.

Hmmm, not sure then. If it's only in Crysis 3, I'd suspect a software problem (driver-related) more than hardware though.
