Is this a safe GPU overclock?

Hello.
So today, I decided to OC my EVGA GTX 770 ACX Superclocked. Not that it wasn't giving me good performance, I just wanted to try it. I overclocked the GPU clock from 1111 MHz to 1214 (which bumped up the boost clock to 1266) and the memory from 1753 MHz to 2000 MHz. I didn't touch any voltages. Is this a safe, stable overclock? Would it affect my temps too much? It has the ACX cooler. The max I've seen it go on factory OC was 71C. Would it be the same number with my OC?

EDIT: Just so you know, I used EVGA Precision X for the overclock, and GPU-Z shows me the overclocked speeds.

It's the silicon lottery, some people get great overclocking chips, maybe you, whereas some don't get great chips for overclocking, with a great cooler like acx, you should be able to go higher, if you have sufficient cooling in your case, you can go higher, a webiste review got 1333mhz, so you are no where near its limits I'd say, jut test it out, http://hothardware.com/Reviews/EVGA-GeForce-GTX-770-SC-with-ACX-Cooling-Review/?page=11 Here is the page where they got that speed, make sure your psu can handle it, and your case fans also :)

Ok, so I should decrease them, right?
I just made the GPU 1168 (boost 1220) and the memory 1847. Is that good?

You should check the temps and voltages , the overclocking process should be a lengthy process and one that you should invest time in it not just randomly turn it up to whatever. The Frequency bump is still a lot you need to do stress tests in order to find the card's sweet spot.

You'll have to test it out. Load up a resource hungry game and go. If you see a loss of FPS, too high of temps or distortions; then it's too much. The memory clock is Okay, but the Core clock gives you the most performance. You might want to kick memory back a bit and see if you can up the Core clock a little more.

well overclocking the memory does nothing really, but on on 780 and 780 ti's you can see like 10fps different on a overclock and no problem :)

check out other reviews first though, don't just read one and think it's all over :) it's better to overclock it and just compare the fps you got with the fps you got before a overclock, only way is to see for yourself :)
