SLI with PCI Express and PCI Express 2 Cards?
Hi guys, I'm trying to set up SLI under Fedora 11 with my existing Nvidia GeForce 7900 GS and my new GeForce 9500 GT.
I've installed the drivers and my system is picking up both cards. I've also added the SLI option to my Xorg.conf file. However, looking in the Xorg.o.log file shows these errors... Code:
--snip-- Thank you for any help. It is greatly appreciated. Also, I'm aware that apart from me using SLI under Linux, this has almost nothing to do with Linux but I don't know where else there is such a high concentration of intelligent people on the Internet that may be able to help me. |
It will be nice to see from the very start and then to the end of the log. Snipping it does not help and I do not like it. I think it is recognizes two different graphic cards of the different models which you have. nVidia's documentation on how to setup SLI is informative about the assigning of addresses for each card and about the requirements of SLI. From what I read and common sense, SLI will only work if two or more cards are equal models. A GeForce7 7900 and a GeForce9 9500 are not equal, so SLI will not work.
Since you are going to buy a video card, spend the money on a GeForce GTX 285. It provides more grunt than two GeForce9 9500 in SLI mode and with more compatibility with any program. You can then use the GeForce9 9500 for a secondary video card. You can watch a HD video on the GeForce9 9500 with the help of VDPAU and play a game on the GeForce GTX 285 |
I looked into getting a GTX 280 but, unfortunately, the only thing stopping me from getting it is that it simply won't fit in my case. Besides, I only want two cards for CUDA and the possibility of going to a tri-monitor setup in the future. The 9500 should suffice for that. Anyway, I ordered another 9500. I'll try it all again when it arrives. Thank you for your help Electro. :)
