High idle clocks while using afterburner. How to get 300/150 like in overdrive?

[stuff_me_good]

Hello, like usually these things google was not helping much and I'm in need of answers, so I turned on here.

I have power color radeon 7970 and since overdrive doesn't support voltage control and is capped at 1125Mhz, I had to start using afterburner. While overdrive can clock to 300/150 Mhz when idling, afterburner doesn't downclock at all if you have not set anything on 2D profile. Okay, that would be simple, but why afterburner doesn't let me set lower than 475/685 MHz clocks to my card? The bios has the idle clocks set already, but the program doesn't let me use them.

Is there any way to get the same default idle clocks that you get with overdrive in afterburner? Would be nice to not set any profiles, just overclock the shit out the card and then the bios does the rest.

I just finished benchmarking Assassin's Creed Black Flag and Saints Row Gat out of Hell on my 7950 OC, to test my digital recorder.

Assassin's Creed Black Flag 1920X1080 V.High 7950 @1.1Ghz CORE i5-2500K @4.8Ghz


Saints Row Gat out of Hell 1920X1080 Ultra 7950 @1.1Ghz CORE i5-2500K @4.8GHz

If you go at the end of the videos, I record MSI AB's stats for a more complete picture, where you will see that the card drops from, 1100/1500 to 300/150 as it should. The overclock itself is done with MSI AB.

I would check the following:

1) Is overdrive in Catalyst disabled? It can cause conflicts.
2) Do you use the latest catalyst?
3) Is ULPS at its default value in AB?
4) Are the automatic profiles in MSI AB's profile tab, blank?
5) Do you have any other weird option enabled, that would lock the frequency in high 3D?

Sure, right after I bother to bicth about this in the forums, the problem goes away. :facepalm: Well it's a good thing that now problem is gone.

I guess it has always been the fact that I think I had the overdrive enabled all this time, since yesterday before I wrote the thread, I ticked off the overdrive(since I was giving up overclocking all together) and after I read your instructions, I decide to give it another go and fire up the afterburner and set some mild overclocks. Voila, it works. So it must have been the overdrive wich has been enabled the whole time before.

Come to think of it, I've always had the overdrive enabled but still used afterburner. Then I set 2D and 3D profiles, but at the time there were some issues with AB and switching between those 2D and 3D profiles gave me some weird flickering on the screen and messed up seriously all flash, youtube, vimeo, etc. videos. So I got rid of AB and just settled on stock clocks. So now I know, all those problems moths ago were also user error and because I didn't investigate enough to realize to switch off overdrive.



ULPS is enabled, but I have single card setup, so I guess that doesn't bring anything to the table, like better overclocking?

Glad the problem is gone! Hope it will not come back!

I cannot be sure if ULPS has some effect on overclocking, because my 7950s are voltage locked and my OC is very limited unfortunately.

It didn't seem to have any effect on my 5850s though. Well the option is there, but I am not sure if it has any effect on Evergreen. Cannot recall.
