Max clocks and temps for R7 260x?

I frequently underclock my GPU clock to 830 mhz and overclock my memory clock to 1800mhz. Will overclocking memory clock this high damage my card? It runs at 70°C after a while and doesn't go a degree up. What are the safe temps for R7 260x?

I use Sapphire TriXX.

70C is perfectly safe. Keeping the GPU clock down is never a bad idea, unless you're really looking to geek out and watch it go. As to your maximum safe temperatures question: AMD/ATI are well known to run over 100C. You could probably push the memory clocks a great deal higher (I don't know a number, but) and safely operate the thing over 90C for a long time.

Best of luck.

Thanks man, very helpful.

Can someone that has overclocked this card give me frequencies?

 
each card will OC to different freq. so its best to bench mark and stress test on your own. I recommend heaven benchmark for the stress testing once you OC it. for example i have 2 friends both with gtx780s and one is OCed about 75mhz then the other with no artifacts. each card can be different.
 

How do I tell if my card has any problems during benchmark?
