OC downclock problem

Hello, i have this "problem" for quite a while now, card is factory overclocked but same thing happens even if i manually overclock. My base clock is 1000mhz on 280X Vapor X Tri X, and oc is 1100mhz and everything works perfectly when i enter game, but if i play any type of video while i'm playing my gpu downclocks to base 1000mhz. How can i disable that, i disabled gpu acceleration in my browser but no luck. I didn't noticed that on my previous OCed cards...

Does the video play smoothly.

The reason you are experiencing this "downclock" is that the card typically sits at a very low idle clock (usually around 300Mhz) to save on power. When a 2D application is required, it typically ramps the clock up a bit (on a 290x typically to around 500Mhz).
You only really see the full clock when you go into an application that requires the whole processing power of the GPU.

For example my 290x's run full whap when in games like skyrim with a crap ton of visual mods (because it needs it) but for older title's like TF2 it rarely comes out of the 2D clock speeds.

Its just the cards trying to power save and isn't an issue.

Yeah i knew that it's not issue but i would love to have my gpu on 1100mhz while playing game and listening music on youtube if possible :). But yeah my gpu when idle is 300mhz and while watching videos 500mhz. If i could disable that power saving like on cpu that would be great, i mean 100mhz is not a lot but if it can run at 1100mhz why not ?

Oh, so if you are playing a game its running at 1100Mhz and when you start playing a video whilst in game it drops to 1000Mhz?

if you are not experiencing issues
this is normal load balancing
example.
If you max clock speed is 1100
And the task doesn't require that
it will bump downward.
As for thermal and power saving reasons

If you was experiencing issues
then I would look more into it
I find my msi 290x Likes to
pick a clock speed depending on
how many screens I have running and how many
3d operations are running.

In contrast.
Gpu clock speed, gpu utilization,
are the two things I really keep a eye on.
as every program and game applys a different
type of load to the gpu.

Try disabling UPLS and adding 'force constant voltage' (use MSI afterburner to do this as you will be able to swich them off when you are not gameing)

Yeah it runs 1100mhz core and 1500 memory, when i play any type of video only core clock drops to base 1000mhz, and it's not overheating or on 100% load... I don't get it i guess it's some power balance option, so i'm trying to disable it, cause this gpu should keep up with Bf4 and youtube at same time. And every program shows same clocks msi afterburner/gpu z/open hardware monitor. I used to play Unity and render a video (using gpu+cpu) at the same time and it still worked ond 1100mhz. As soon as i open video "nope nope can't handle this brah..."

I think i tried before forcing constant voltage before, but i'll try to find that UPLS thing... thanks everyone
