PCS+ 7950 powersaving mode?

[Menty]

Hi,

I have noticed with my 7950 that after a while being dormant the gfx card will drop down to half default speed (440 core).
This should be fine but this week noticed that my jittery BF3 session might have been attributed to this.
I had AB open while playing so it recorded my core speed at 440 for the duration.
I then ran Heaven (without changing anything) and noticed it was also jittery whereas normally it would be fine, checked and the speed was still 440 core.
When under load the card should revert to its normal speed but it did not.

I can quickly correct it by resetting it to default in AB but I should not have to?

The powersaving function is not working correctly or am I missing something?

Anyone had a similar situation with the 7950?

Cheers

Try using the latest drivers would be a random guess from me.

I think those might be what I'm using and the comments from other's are not generally good.
Think I will roll back to 12.1 and give that a whirl.

Are you only using AB to monitor, You have no clock profiles or anything like that ?

Yes just AB to see what the graphs show afterwards.

Clock profiles?

You can make your own 3D and 2D clocks in AB, but for the time being i wouldn't with a 7xxx card as AMD have been making lots of changes that can break that aspect of AB.

per unwinder:

/XCL eXtends Clock Limits for official AMD overclocking APIs. Which means that it also extends clock limits for CCC or any other other vendor specific tool using official overclocking interfaces provided by AMD. Considering that it is using official AMD overclocking interface, it is compatible with ULPS. This method is equal to flashing new VGA BIOS with extended Overdrive clock limits.
However, this method uses hidded VGA BIOS emulation debug feature of Catalyst driver. Once AMD decide to remove it from driver, it will stop working. It is also necessary to re-extend clock limit after driver re-installation because VGA bios emulator resides in Catalyst registry entries.

Unofficial overclocking uses old undocumented "hole" in AMD driver, which allows to re-program PowerPlay table and bypass Overdrive clock limits. AMD used this unofficial interface in the past for their internal AMDGPUClockTool. Currently the "hole" is not supported by AMD in any way, it is incompatible with some AMDs own power saving technologies (ULPS), it has many side effects due to "nice" AMD programming skills (such as resetting fan speed and powertune to defaults, etc, etc).
