I know that there are no motherboards with 2 pci-e slots available today. But I was refering to the old fashioned pci slots :) I have seen a picture on the webpage of the openvidia project with 6 pci cards inside, but there is no real information to be found. > > Anybody experiences with such an unusual combo ? > > we have several systems running with dual fx[3|4]400 and also dual > 7800gt. under linux you can configure dual head as well as quad head > mode. we also use a dual head setup where each head has a twinview > setup. as for 64bit you should be aware the cards itself are not > really 64bit ready because they get mapped below the 4GB into local > addr. space. this means you want at most 3GB memory on the board or > some certificate from the board vendor that the memory range claimed > by the pci-e device is "redirected" with bios magic (actually > supermicro does this on the x6-dai-g board). nvidia has section in > their linux driver readme (76.xx). you should also consider a > dual/dual-core cpu system to keep the pipes filled :) It is not so much a problem keeping the pipes filled, the graphic cards are not used to produce continous scene updates, instead each of them produces a single image every few seconds. I just have one application running multiple times on the system, each of them having a different big model loaded. Transfer rate is not of any concern nor is it processor power (of course it wouldn't hurt if both are available ;) ) Regards Matthias ------------------------------------------------------- SF.Net email is sponsored by: Discover Easy Linux Migration Strategies from IBM.
