How do I Stop GPU Downclocking?

[PleXya]

The core clock and memory clock of my ASUS 7950 Radeon HD downclock when I have a YouTube video playing while I'm gaming, when I'm using certain programs on the desktop, when I'm using OCCT (just the core clock), and when I'm in certain parts of PC games

Question: Is there any adjustment that can be made to make sure that both clocks remain consistent throughout any task?

I don't think this is a core or memory voltage issue. My overclock is stable at:

1050 core clock (MHz)
1600 memory clock (MHz)

1150 core voltage (mv)
+20 power limit (%)

I've passed many 30 minute tests with OCCT with error check enabled and I've also passed many unigine engines. I've also passed 3DMark 11 tests

I'm currently using MSI Afterburner.

My CPU overclock is stable @ 4.5 GHz with a 4.5 GHz cache; passed 8 hours with intel extreme tuning utility

Mobo BIOS is updated to the latest version

GPU is updated to the latest beta driver (15.4 Beta)

Any help would be greatly appreciated, thank you!

Download MSI Afterburner and under unoffical overclocking mode set 'without powerplay support'.

Your Video Card is "down clocking" to prevent itself from overheating and frying. It is a safety feature. It is being allowed by the manufacturer to run at a speed that it cannot support for long periods of time, and when the heat builds up to the limit, it steps down its speed just a little bit. That is how it is designed to function. It is NOT a problem.

Thank you for the suggestions. This is the thread that helped me STOP the GPU downclocking:

It was downclocking due to AMD's PowerPlay being enabled

SOLVED!

Wrong. PowerPlay is a feature designed to save energy.

Energy = Heat.
