XFX ATI 6870 Core Clock weirdness...

[Dnabb10]

So, the 6870 core clocks fluctuate based on how much processor you need. I've noticed that, for example, when you play World of Warcraft it will go to 900Mhz (full capacity not overclocked). But, if you're playing World of Warcraft in windowed mode WHILE you have youtube up, the clock will idle at 300Mhz...anyone else have this problem? Oh and I made sure to check, once you close youtube, the core clocks go back up to 900.

I had this problem when I changed drivers on my 5850(flashed to ASUS, clocks at full capacity are 800/1125) to 10.11 ...on desktop it goes 400/300 and causes my browsers to go all fidgety while I browse (I run 3 monitors, use individual screens, not eyefinity)...it will clock itself to 400/900 when I have youtube tab open (or any other video), and everything goes stable.

In WoW (full screen, single monitor) the clocks fluctuate from 800/1125 -> 800/900 -> 800/300 causing the game to be unplayable. Hello system restore and old drivers! Problem solved for me at least. I won't be switching drivers anytime soon from my 10.5 or whatever it is I am using.
