I bought two 980 TI Strix Factory Overclocked cards.
I run them together in SLI and set to a custom "My Profile" professional mode overclock with the boost clock set to 1317MHz (the factory rated overclock that the card advertises),
because in the regular simple mode selections (gaming & OC Mode) the card NEVER goes above 1119MHz (I seem to not be the only one who has this problem, also see here:

Anyway, my computer will suddenly shutdown while playing intensive games. It happened more frequently (i.e. after about 10mins of gaming) if I did it with a high personal overclock, i.e. 1400MHz. If I leave it at 1317MHz (rated factory OC), it shuts down after about an hour, sometimes two hours of gaming.
I am now testing it out running it at 1200MHz to see if it still happens.
Temps are 80-83C for the top card and 70-75C for the bottom card.
I've had the computer shut down on me right away upon starting a game (i.e. long before the top card reached 80+C), so I don't think it's temperature related (also nvidia says max temp is 92C for the 980 TI).
I have a feeling somehow the cards aren't stable. But I don't understand why it shuts my PC down?
While testing for the max overclock I could reach with the uniheaven benchmark I hard the driver restart and other problems, but never a sudden shutdown.
Any ideas? Should I RMA the card(s)?
Thanks for any input you guys might have!
