Left pane, second box down, "PowerPlay" there will be a value for "Max Memory Freq. (MHz)" and whatever value you have in there is the absolute maximum the card will accept.
Question for you iSuX (just cos I think you might have the answer).
I've modded bioses with Polaris 1.6.7 and the One Click Timing Patch, etc. but I have noticed on the 570s that the max freq is 2250, with straps going up to 2000. However, when I try to OC above 2000 it just crashes. Anything 2000 and under runs fine.
So, my question, do I need to be adding extra timings above 2000 to allow it to OC above 2000?
I also see in the memory portion, there are freq and voltages up to 1750 mhz, but nothing above. Should I be adding in more freq/voltage pairs as well? Or is all of this unnecessary?
...
Happy mining everyone.
