Is the memory clock suppose to be running at Max speed when watching youtube?

it would have to be way over 5 watts as even my power usage goes up more than that on youtube even with my memory staying at idle speeds.

Yea, this issue drove me nuts with my 5850 and really turned me off to AMD. My displays would flicker every time a web video was loaded because of the changing memory clock. The "solution" was to just peg the memory clock constantly. Absolutely zero problems since dumping AMD and picking up a pair of Nvidia cards.

I still have a 5850 and it never flickers (the only problematic thing is with multiple monitors), the behavior with flash video (on IE or FF, I haven't tested Chrome with this card, and I've heard it's difference because it doesn't use UVD the same way as FF/IE!?) accelerated is that the card runs with the UVD clock (400/900), while it runs at 157/300 with hardware acceleration off,

nothing wrong, the only trouble is that it locks at 400/900 with any flash video open, so if I try to play a game with a flash video open it's going to stay at this clock and not the full clock until I close the video, which makes no sense, but the UVD clock overrides the catalyst settings I think, the only way to change this clock is perhaps editing the bios!?
the easy way is just to disable hw acceleration, almost anything can handle 1080p youtube anyway.
