350 MH/s on each GPU is what you should be getting...

sorry i ment 350 per card, since each card has 2 gpu's i should be getting 700+ per card

card 1 (device 0) is now running at around 700
card 2 (device 1) still having troubles, 1 of the gpus is idling at 157mhz...

I had that problem with my 5970 last year when I had it. I had to manually adjust the profles idling speed manually to 900 core, or else it would stay at a super low idle speed.

thanks guys it's now sorted, the unplug and replug method did it in the end, the probplem was, i assumed:

Device 0 was card 1 - GPU1 GPU2
Device 1 was card 2 - GPU3 GPU4


turns out its more like this:

               Card 1 |   Card 2
Device 0 - GPU1   &   GPU3
Device 1 - GPU2   &   GPU4


so before the unplug method wouldn't work because i was starting the wrong devices.

thanks again every1 who helped Smiley

Have you tried dummy plugs or the plug in monitor, start client, then unplug trick?

If you do the monitor trick this is the order.

1) Plug into first card
2) Start miner on first card
3) Unplug monitor
4) Plug monitor into 2nd card
5) Start miner on 2nd card
6) Doesn't matter if you want to unplug and put the monitor on the first card

Did you not read the rest of the thread? That's exactly what I posted before.

Relax. I quoted you before about you suggesting it. He just didn't say whether or not he did it so I just wanted to make sure he tries it and correctly if he doesn't know exactly how to do it.

getting closer,
what i needed to do was run two instances off one device, i now have 2 off device 0 at 350 each
but device 1 is down to about 150 each..

Interesting, I dont have dual gpu cards so I didn't know that. But when you pointed out when you ran it on Device 1 it was at like 150 Mhz and wasn't in CrossFire. It's the common side affect of people not knowing the have to do what dingus suggested above or what I posted for the 2nd card.

Are you sure? Have you actually done this or is this speculation?

WTF there is all sorts of crazy wrong information here.

1.  There are two devices per card, your devices will be -d 0 and -d 1 (or -d 1 and -d 2 depending if your CPU is listed first).
2.  You will have a total of 4 devices, -d 0 through -d 3
3.  A stock 5970 will get at best 350 MH/s per core, 600 - 800 is the combined output of both cards.

You need a dummy plug for the second card if it is not CrossFired "OR" you can plug a second monitor into the 2nd card.

Also if you use a dummy plug. Make sure you go to Display and Enable the psuedo display and Extend Desktop.

What happens is if you don't have the cards Crossfired it detects that the 2nd card is idling if there is nothing connected to it. Even if you are running a gpu mining client on that card. It will not up clock it to the normal speed.

Also, if you don't have a dummy plug just start the first 2 instances for the first 5970, unplug your monitor and plug it into the 2nd 5970, and then start the 2nd 2 instances of your miners.

On mine I had to install catalyst a 2nd time in order for windows to properly detect both cards.  Try that and see if the second card is picked up.

Are the cards Crossfired or not?

checked catalyst and it says both cards have 90%+ activity on them.. when i close device 1 the second card drops to 0%
so device 0 is card 1 and device 1 is card 2...

did not know that, thanks, but when i try to run the 3rd n 4th i get this error

http://imgur.com/99B9m

device 3 n 4 aren't detected...

the card is detected as i have the option to change settings for it in catalyst
when im running just the 2 instances of phoenix the 1st cards fans are 80%ish
and the second card seems to be just idling, so this lead me to deleive devices 0 & 1 are both on the 1st card.

also it seems im runnign catalyst 11.5 if that has anything to do with it
