MY Xfire 7950 Gigbayte is 80c in Heaven.....too hot????

Check your VRM temperature sensors (GPU-Z shows them IF your card supports it, I'm not sure if Gigabyte does though)
They tend to run 5-10 warmer on my Twin Frozr and according to this test, up to 30c warmer than the GPU Temperature sensor

It does not monitor the powerstate and re-enable X clock settings. Think of it more as a manual app, a dumb app in essence. AB is much better for day to day overclocking due to it's profile capability. The other thing you have to confirm is that you've disabled hw accel in everything that uses gpu acceleration, though even after doing that it's not a guarantee but its the best practice that counts.

Personally I game with AB and bench with Trixx. I can't live w/o AB's OSD server. On boot up I have nothing loaded, ie. no AB or Trixx.
Hm, in my experience Trixx doesn't work the way you are describing. I tried a little test and took some screenshots of it.

1. http://i.imgur.com/vdb0ypZ.jpg
Overclock applied in Trixx. Youtube with video paused. Clocks are automatically down to 300/150 and voltage is also lower.

2. http://i.imgur.com/TW6eC7p.jpg
Video playing @ 1080p and HW acceleration enabled. Clocks seem now to be at stock speeds (900/1250) and voltage is a little higher, gpu usage ~20%.

3. http://i.imgur.com/oryLNq0.jpg
While playing games the clocks go to the true overclocked speeds.

The only bad side with Trixx that I see, is that it has to start up with Windows to apply the clocks. But if you have an SSD and plenty RAM, I don't think it matters much.

Scratches head, it did exactly what I said it would do. Trixx cannot keep the cards from changing powerstates. YouTube or Firefox etc are all apps that can kick the cards pout of 3d clocks amd into the various built-in powerstates, like for ex. uvd, idle etc. There's not much more say on the topic.

Ah ok, in that case I must've misunderstood. smile.gif
So I guess it's just the combination of overclocking and Powerplay on that caused all the glitches with AB. I suppose Trixx by default disables Powerplay? In that case I think I'll just go back to AB and set "UnofficialOverclockingMode" to 2 and save the system some resources by not needing to run the app in the background.

Edit: Scratch that, if "UnofficialOverclockingMode" is set to 2, the clocks just stay at the same overclocked speeds all the time. With the setting set to 1, I get the same glitches and flickering again as before. Must be a bug in AB I guess, for now I'm going to run with Trixx.

that is pretty hot isn't it... guess you need a bit more airflow around the card, but 80C is still relatively safe, just might make your card a bit less stable if you tried overclocking, a lot of chips overclock notably better under 65C (you want water at that point anyway really).

I pushed it to 1200 core +20 power and 1460 memory to get 80c.

No, you cannot disable powerplay but you can bypass it with AB using unofficial mode set to 2. But that only works in conjunction with properly configured 2D and 3D profiles. I would suggest you read the link with the video I posted earlier to get a more complete understanding of how the powerstates work and the overclocking process. It's not complicated but it has a lot of nuance or options to weigh.

Is it time to pick up that 2nd 7950 or move up a little higher?

Good time meaning.......

Technology doesn't get more expensive as time goes, but less. I got 2 gigabyte 7950 cards rev 2 with 6 games for $400 however sold 3 games voucher so my total cost for 2 7950 and 3 games is $375.

When these first hit the market 1 card was almost $500. Good deal? Yes in comparison to buy two and 3 games for $375 vs 1 and other games at almost $500.

Ok, thanks for the tip, but in my case I feel it seems just easier to run with Trixx and have powerstates functioning properly from the get-go.
