Where are the clock settings stored?

(In interest of thread consolidation, a compound question of similar sub-questions)


1.) Besides natively editing a card's BIOS (no longer possible), is there somewhere in the system that I can edit/change/view the "native" card clocks/modes? (...rather than "forcing" it through MSI Afterburner)


2.) Is it possible to "listen" to see what program or service is causing a card to jump between clock modes? (I've already disabled HW acceleration in all browsers and Flash Players)


3.) Strangely, even though Afterburner hasn't been running or opened since last week, my card can "jump" to clocks I've previously forced in Afterburner. It's like Afterburner is still running, even though it's not -- the card obeying some residual settings from it somewhere. Where might this be stemming from? (I've never used or even unlocked AMD's OverDrive, only OC'ing through AB)



Problem:

I'm getting sporadic and random clock changes on my card (7950, AMD 13.8B2). I'm trying to either find the source that's instigating the clock jumps, or I'd like to edit the clocks to set them all at a static memory speed (to prevent the flickering).

I used to do this in RBE Editor, editing the clock settings inside the card's BIOS. But due to BIOS signatures and checks, it seems this is no longer possible.


I've been on these drivers for a couple weeks and haven't seen the issue till now, so I don't believe they're the problem. I also haven't really changed or installed anything recently. I've already disabled all hardware acceleration in my browsers, Flash players, and movie software (i.e., no DXVA). I'm also not running any software that would be using 3D mode (at least visibly, that I'm aware of).
 
incleasesing clocks thorugh afterbriner is semi-permenant.

Its creates a "soft-powerplay" table in the registry.

Once you create it, it doent need to be created again untill you re-install the drivers, nor do you need to run afterburner to access the increased ceiling.

see here for some tools:

Possible causes for clock spikes: GPU video acceleration. GPU Web page acceleration. AERO acceleration.
 
Ah, gotcha. Good to know -- thanks.

Is there any reason to continue using Afterburner (or rather, keeping it open)?
