So what is the consensus on how many 7970's can run on one rig ? - page 2.

I understand the 8 card(gpu) limit but if I remember correctly, people just couldn't get more than 5 7970's working no matter what they did.

I have 8 GPU's going on one rig now, but all 5970 and 5870's. Most of mine have 6 gpu's minimum.

So I was wondering if those who have 7970 rigs could chime in. I remember jimm_64 saying he couldn't get more than 5 running in windows and he has many 8 gpu rigs (4x5970's)

I have the MSI GD70's and all the good mining parts, seasonic 1250 watt gold psu's ,etc.

Just don't want to buy a 7970 and be stuck with one extra as I have a rig with 3x7970 flying away right now, but I would like to max it out for efficiency.

Thanks.

The ATI drivers limit limit to 8. 32 bit Windows limits to 4. Most motherboards have their own limit tho, 3, 4, 5, etc.

I was under the impression that the limit was 8 GPU per AMD, windoze is 8 if you have the correct version, but most is 4 or 6 gpu. Hope you have a Large or multiple power supply for a rig like this.

I thought I saw that 5 was the limit in windows 7 64bit.

Anyone get 6 to run yet with newer drivers or a specific driver ?

I have msi gd70 motherboards so I'm all set with pci slots, etc.

Also, do these run OK with x1 risers?

Thanks in advance.
