Could you make a table with all yours miners/configs? Or would be too much work?
Yeah, when I get a chance.
Just found the voltage limit @ 840mv @ 925mhz... wow.
What is the MH/s and wattage at this voltage/clock?
This might blow your mind...
Wattage is measured at the wall plug as total system draw. Subtract the 290 watts of the system idle from the total then divide by 3 to get individual 7970 power draw. Mining results are of 7970 power draw only. My power supply has about 92% efficiency but I did not factor that into the results.
Three 7970's:
System Idle: 290 watts
Mining: 925/1375mhz, 1.17v, 630 watts
Mining: 925/340mhz, 1.17v, 625 watts
Mining: 925/340mhz, 880mv, 360 watts
Mining: 925/340mhz, 865mv, 345 watts
~1650mh/s
Single 7970:
System Idle: 290 watts
Mining: 925/1375mhz, 1.17v, 210 watts
Mining: 925/340mhz, 1.17v, 208 watts
Mining: 925/340mhz, 880mv, 120 watts
Mining: 925/340mhz, 865mv, 115 watts
550mh/s

Got them undervolted to 890mv @ 925mhz...
Try and get them at 0.9V and at 1125 MHz !
What BIOS did you have to use ?
Nah, Just trying to find the lowest core voltage right now @ 925 so they aren't so damn loud.
BIOS is just what it shipped with.
EDIT: 860mv now...

Ya, I'll post some results tonight.
new phoenix 1.7.3 should support it too.
Just try them all
Just try them all

Soo.. got them in.. What miner supports 7970's?
OP, just make sure your cards don't get delivered like this http://www.youtube.com/watch?v=PKUDTPbDhnA
Or they got send like this one: http://www.youtube.com/watch?v=6wpkbYL7wFA&feature=related
So that's what they mean by 'ground' shipping.

Not sure if you want to do all this but.
Kill-a-watt the following:
idle w/ only one card installed
idle w/ all three cards installed
full load w/ 3 card mining @ stock
full load w/ 3 cards mining @ highest stable overclock
As far as 5970 comparison yeah AMD changed numbering scheme. The 5000 series direct equivalent is the 5870.
5870, 6970, 7970 = highest single GPU card
5970, 6990, 7990 = dual GPU card
Still the 5970 is the king of the hill in terms of price, density, and efficiency right now so it will be an interesting comparison.

That's simple enough.
He forgot full load w/ 1 card mining at stock and another at highest overclock. This will better power numbers to work with (including the overclocked watts)

this will be good as DeathandTaxes has triple 5970 rigs to compare with. All my 5970 rigs are 4 per, except one (3x5970 + 1x6950).
We should not really compare these to 5970's though, being that 5970's are dual core and for whatever funky reason AMD did not keep the same numbering convention for 6970 and 7970, which are both single core. I would be very curious to see these compared to 3x5870 and 3x6970 though.
And also, make sure you kill-a-watt at wall on the machine before you run the cards as well. Would be nice to simulate some very light load on it with and without the cards before mining as well.
cheers

looking forward

Summary, haw fast is Yours quad 5970 ?
EDIT: NVM - got it from BFL thread - nice, i got 2.5GH from just 6 GPU
