HD 6950 Power Control +MSI AB - Page 5

post #41 of 49
Power consumption doesn't really change too much, and nor does it give all that much more performance. At 0% (let's call the limit 200W for example at 0%) it will lower clocks (750Mhz for example) if the card tries to exceed 200W barrier in a really stressful application, but if you set to +20% then you can allow it to use up to 240W so it won't underclock so it may give more performance in really stressful apps.

Anyways the next version of Trixx will support voltage for all 6900 cards and powertune adjustment and no need to mess with annoying config files, so bye-bye Afterburner. =D

Too bad I can't I bye bye to it, I have a screen dedicated for temperature monitoring and TRIXX's gadget doesn't show multicards GPU usage etc. Is there any way to use AB without using the clocks? Isn't it so, that AB doesn't automatically apply the clocks when you start it unless you press the 'apply' button and don't have 'apply overclocking at startup enbaled' doesn't it?

Ok. No extensive 3DMark testing needed. I have confirmed, at least for my system, that the powertune stays active with afterburner active. I simply ran Furmark with powertune on 0% and monitored core clock with afterburner. The core clock throttles just like Razi3 said. Then I set powertune to 20%, applied overclock settings in AB again just to be sure, and ran Furmark again. No throttling this time. Here's a screenshot where you can clearly see the core speed throttle on the first run but not the second:

Very nice. Ill try that to.

Its when you overclock beyond CCC limits that Afterburner won't support it.

I had no idea. Sorry for the fuss
I'm really just using afterburner for the custom fan profile

I am running at 950/1300 @1.25. pretty sure that is over CCC limits for a 6950. I get the same type of graph that Dissentience gets if I overclock with afterburner but do not use the +20% in CCC. If I put the CCC to +20% then exit out of CCC, I get a constant clock of 950. If I could figure out how to get afterburner to not throttle without CCC setting then I would never install CCC. I use Radeon Pro for all my visual settings.

so i got it to work, but it's sort of tedious.

if you have afterburner to automatically load 2d and 3d profiles, you have to scrap the 3d profile because each time you load new clocks, you need to change the ccc powertune to +20% even though it says +20%.

If you are running 3d overclocks 24/7, you may not need to do this every time or every time you boot up (I haven't tested it).

So you load up 3d clocks in afterburner. Go into CCC and the slider will be at +20% and the apply button is greyed out. Move it to another value (anything), hit apply. Then move it back to +20% and hit apply. Now you are good to go.

so power control does work with AB? lol, sorry if im being redundant. I was ay 950/1435 @1.14v +10% control running fine. After reading a few threads, its suggested turning overdrive off, which resulted in crashing. So i turned it back on, and still crashed. I am just now realizing that i never increased the power control after resetting overdrive, and i'm hoping that why i couldnt even hold 925/1415 in any benches.
