Neither that's what it runs at since the day I got it, I'm running water so it's cool, but nope, I just maxed the settings at 2200mhz/1900mhz and off she goes. The maximum boost it records I've seen in GPUZ is 2164mhz, it never goes any higher no matter what I do... but it's stable enough to run war zone for 4 hours in a session on Saturday evening... and folding... Max Junction Temps in a 21C room is 78C I think it was, I've seen over the last few days but I reset GPUZ this evening so can't double check.
My old 5700XT wasn't as good as this one, it wouldn't clock the core above 2146mhz, so was I think if ememory serves around the 2080mhz on boost give or take... with the memory at 1900mhz as well.
