Highest Stable Clocks for Quardo FX 770m

I've been trying to overclock my 770m but Im not sure how reliable my artifact scanner is(ATI Tool 0.27). So to double check, what kind of stable clocks are you guys getting? Also if not too much trouble, what's the max temp under load and 3DMark scores for your clocks if they differ from those already reported.

At the moment I'm running 600/900/1650 (core/mem/shader) with a max temp of 89C (normal heavy load is 87C) and 3DMark06 of 5950. Haven't gotten any artifacts yet but Im hesitant to take it any higher because of the old scanner and already high temps.

For reference, stock is 500/800/1250 under which my max temp of 82C and 3DMark06 gave me 5150.

 

That seems pretty sound, i wouldn't take it any further due to temps, the high temparature threshold is around 90C and your sat on 89 hehe.

Them clocks are nice though

 

Well the thing is, these temps were reached without a cooler. If I use a cooler my max temp becomes 80C so there is still room to push it higher. (I know...im greedy )
