Thread Starter 

As tittle states is this normal? Happens when I watch videos only kinda weird, like when I use to have an OC profile and it switch when starting a game it seems.

Seems like a problem with the video card. Try furmarking it and watching your temps

I didn't see anything wrong in the video, but it is early.
Can you explain what's going on?

It is the screen flicker you are talking about, right?

Try different drivers... Is it only youtube videos that causes it.

If it's the flicker, that's normal

When watching youtube videos (or other flash content), the card downclocks A LOT to idle. That clock shift creates the flicker. When you exit the window, the clocks should shoot back up, and it should flicker again. At least, thats' what happens with my 5770.

To expound on what DeZant said, it's a problem with some of the newer drivers. I was on a nonreference pcb pair of crossfired 5770's for a while. Cat. 10.4 was the best for eliminating things like this as later drivers lowered 2d clocks too much.

Unfortunately, I had no luck with drivers past 10.4 (Open GL issues). So I stopped trying new drivers after 10.7. I can't comment on any between them & 10.12 (when I got my 5870). 10.12 didn't have any problems like that. However, 11.1 did for me, but 11.4 preview is great.

If it's the screen flicker you're talking about then thats normal, what causes it is the RAM on the card changing speed to decode the video. You can fix it by customising a bios so your graphics card ram stays at full speed all the time or turn off video acceleration of flash video.

That only happens when you're gaming and at the same time try to watch a video?

It's screen flicker. Used to be a huge problem with ATI card with dual monitors. They fixed it with 10.6 but it seems to be back. I dug-up my old nvidia one just do drive my second monitor.

There's nothing you can do, it's because the 2D clocks are so low to save power. You can flash your bios with new 2D clocks but it's complicated and risky.

When I have 2 monitors plugged in, the 2d clock is ramped to 500MHz (compared to 250).

That should be plenty.
