If you're wondering if your device should be labelled as Cypress, no, it should not. 69xx series are part of the Northern Islands architecture, I believe 6970s are caymans.

If you're wondering about device #, that varies by computer, device 0 happens often, sometimes device 1 happens.

You don't really need to ask in such a cryptic way.

So it should be something along the lines of:

Device:
  • Cayman

You forgot to mention the most important part : the voltage of your GPU.

I used GUIMiner for quite awhile and decided to give Phoenix a try a couple days ago. I just recently posted it into https://en.bitcoin.it/wiki/Mining_hardware_comparison .

I am able to get 423 mh/s. Stales are a little higher but not too much more. Here are the settings I used if you're interested.

ATI Tray Tools, Clocks=995/331.25, WORKSIZE=128 BFI_INT AGGRESSION=11 VECTORS ,68C @ 65% Fan, HAF932 Case

One other thing to note. I can surf around on my pc and the hashing never drops below 410. With GUIMiner if I added -f0 I could get about 415 max and the pc was unusable.

Don't mean to hijack just figured I'd let you know.

Also, it's a Sapphire 2GB card in case that makes a difference.

Can you just post a screenshot? Your GPU doesn't need to be mining, I just need a screenshot.

what kind of performance increase does BFI_INT really give?

Also interested in knowing this...as far as I know I think it's just an optimization to improve performance on AMD cards.

Is there a reason you don't use BFI_INT?

I thought it was directly integrated into the program?

Edit: how do I use it?

Can't grab a screenshot right now, but I use "-v -w128 -f15"

My 6970 is clocked at 940MHz and in the Overdrive control panel I set power to +6%

With these settings I get 398-402 Mhash/s.

Without the +6% power, '-v' causes a performance decrease.



What does it says next to "Device"?
