Max i have seen so far is 70c.

At the moment i have:

+40 core
+200 memory

Seems to run stable in heaven. What do i try next? Is there a guide anywhere about this new overclocking method?

You just use the exact same method as with any other graphic card. See this post i made earlier in this thread. The only difference is you can't change the voltage yourself and that's it.

so you dont need to touch power control or core voltage??

You can't even change the core voltage, it won't do anything. I think on the Asus model you'd want to set the min voltage to 1.175 and increase the power target a bit, try 121% (max) and see how high you can get and then once you're at your max stable overclock at 121% start bringing that down and see if you end up boosting higher. If dropping the power target doesn't increase performance or causes instability, then put it back at max.

from what I've seen if you raise the power control it will "self boost" way higher. And the core voltage is locked so you can't change it anyway

Also, from what I've seen, the default Asus fan curve is really bad. In a couple of the reviews, the card would be at 78C and the fans would only be at like 35%. You definitely want to make a custom fan curve so you stay below 69C at 100% gpu load. This might not be true of the Asus model, but with the reference 670s they start throttling the boost at 70C.

I have never seen my 670OC go above 91%, let alone close to 111% (max on GIGABYTE). No matter what game I try.

Dude thats great. It has some way of knowing what each card can handle. It sounds like you got a beast if its hitting 1241 at stock. Really drooling over the DCII now.

But the 70c thing sounds like reference cooling. Make a better fan curve. My windforce maxes at 55c with 50% fan.

Every Asus TOP will hit around 1250 at the stock factory overclock. It's at 1137 boost, so if you add the kepler boost of 120-180 (that's the range i've seen so far), then it's a minimum of ~1257 and a maximum of ~1317 depending on luck.

yep mines running at 1267mhz standard and if i set it to 1170mhz boost clock i get exactly 1300mhz core. Problem is even at 100% fan it goes over 70c then starts to throttle. I'm getting the hang of it...the max power target for my card is 0117 which means it runs at 1300mhz or whatever the maximum boost clock is until it hits 70c.

Im not so sure ill bother overclocking it much if it throttles at 70c anyway. If im getting 1267mhz core standard with my card, 1300mhz doesnt seem to make much of a difference other than a maybe the odd FPS and reaching 70c quicker.
