Sleeping Dogs uses a lot of wattage on AMD cards, be careful until you get it under water. Make sure you have the power limit at +20%. Sounds like you exceeded the cards TDP limit and it shuts off to prevent damage.

Not sure setting one then using the other may conflict. Trixxx should have a power limit in there of some sort. It did when i used it last. I suppose you can try setting the power limit in CCC then apply clocks in trixxx maybe.
Jim it could be your psu crapping out. It does the same to me with my 7990 on a 750W psu. Does it crap out on the very last scene indoors? Something about that part does it every time for me if i run a big overclock on my 7990. Orangey reported something similar on his 850w psu with 2x290's water cooled.
Well i can go up to 1200/1690 maximum depending on the bench. However sleeping dogs flakes out around at 1140/1650 on that final scene. Pc freezes then powers off and restarts. Just sleeping dogs that does it. For gaming though i just run stock clocks of 1000/1500 as i enjoy the quiet 'Auto' fan profile.
This guide was for Tahiti and older AMD cards but most of it still applies. I should do a new one and will put it on the to do list.
AUX is basically PLL voltage. It does very little but it may allow you to overclock the memory a little bit further. With Hawaii though memory overclocking is tied to core voltage mostly. So if you need more voltage to overclock the memory further, increase the core voltage. Best to focus mainly on the core and overclock the memory afterwards once you've maxed out the core.
I think so. I'm not totally convinced on the benefits or negatives of AUX yet. However it should allow you to eek out a bit more overclocking headroom on the memory if and when you get a black screen. Keep an eye out for reduced performance (lower benchmark score) when overclocking the memory. Then you'll know you've reached the limit, or you can try adding some AUX.
Use 13.12 drivers and ensure you have +50% power tune set. If you get a crash make sure you restart the pc and reapply clocks before trying again.
It's been a while since i tested it to be honest, but from memory i don't recall there being any difference. If you have two bridges attached only one is used.
