ULPS is a power saving feature enabled on all cards but only works on slave GPUs.
ULPS acts like PowerPlay/ to a certain extent, but is a step further in reducing the idle power consumption of slave cards.
ZeroCore acts like ULPS does, but works on master and slave cards (drops total power draw to zero, using secondary core during standby).
I think ZeroCore is part of PowerPlay.
Correct me if I'm wrong. redface.gif
Now why certain PP functions work when it's supposedly disabled, I don't know.
My idle clocks were correct when I disabled PowerPlay with the release drivers and throttling went away...
Not anymore it seems (normal idle clocks).
I think I can have my own "KHAAAAAAN!" moment now...

That's a good summary. I just added a little more info on ZeroCore.

Yeah was using a flashed Asus Bios. My card just did not like it. Tried all methods of flashing and re-flashing and gave up.

Yeah good summary.
Strange, the full clocks issue with AB, is this with the new AB beta? I was using AB a few days ago and downclocked fine for me.

Using AB confused the hell out of me. frown.gif
I was seeing this when I should have been seeing that if you know what I mean.

Like unofficial overclocking set to 1, that shouldn't disable PowerPlay but it does.
Anyway... I was wrong with the terminology.
I confused certain features of PowerPlay with ULPS.
I thought ULPS disabled on a single card would actually screw with idle clocks, but it was AB or the drivers (in conjunction with each other) that did.

*sigh*

mmm well i'm using the new AB now and it is downclocking fine for me....

UO 1 doesn't disable powperplay but if you think about it, by existence it cannot co-exist with powerplay. AB wants to keep clocks at X value, all the time according to your profile. Powerplay wants to downclock whenever it sees low load on the the 2D desktop. The values in powerplay are not compatible with AB's minimum profile. Thus it's a conflict and neither wins and this is why we get strangeness from AB. You should disable powerplay (in fact all of AMD tech) and solely use AB for full control.

1. 1.45 volts is fine on SandyBridge, depending on your temps. Heat kills hardware, not volts (within regulation). What is you gaming/folding temps?
2. You need powertune if you are heavily overclocking your card and are being throttled during benching/gaming.

That's with unofficial overclocking on, right?
Did you flash your card to the "unlocked" BIOS?

1: I would say it is fine assuming temps are ok.
2: Makes the performance near tdp limits more constant, will not drop fps violently up and down. So it is a good thing.
