Hi Guys,

I have just got my R9 280X and it comes with Boost clocks of 1100.

Well I've always had cards which had a "speed" none of this Boost stuff, but I've noticed during gaming that my boost clocks haven't kicked in, When I boot windows up and do a Render test in GPU Z it did, but this morning even a Render Test doesn't initiate the boost clock.

any idea?

How hot is the card when it is NOT entering boost clocks?

EDIT: Also note that the card will not do boost clocks unless it is in a 3d state like gaming in FULL SCREEN mode!

60C top, using stock fan curve, it doesn't even hit 30% fan,

funny thing is, it has started to run at 1100

Do you have MSI afterburner installed? If so you can put in a game and game for a few minutes then look at the MSI clock chart and see what the clocks were while gaming in full screen mode. I have a feeling your looking at the clocks when the card is not in 3D mode.

Nope, I don't use Afterburner but using GPU Z and Aida on my secondary monitor and got 1000mhz clock however the game only pushed to 80-85% so maybe it was that.

I've added a 10% power limit,

Would that cause it to work sometimes, as I've noticed sometimes it is Boosting to 1100, sometimes it is not.

I suppose possibly, the whole thing with the power limit is that once it hits the cards TDP ceiling it will throttle, unless of course you raise the power limit in CCC, that just gives it a greater overhead, not sure if it would prevent the card going into turbo though.

The best way to measure really is to download the Valley benchmark and run it, then go to the thread and compare scores with 280x's running at around 1100mhz, if you are comparable I would suggest you have nothing to worry about, I could run mine at 1100mhz to see if it helps, there will of course be some differences due to cpu's and speeds but it would give an indication.
