1) Message boards : Questions and problems : Running two video cards (Message 25357) Posted 11 Jun 2009 by Desiredconcepts Post: Ok, So I got home and got it set up it looks like its showing both video cards the problem is its showing it as two 8800GTX cards and thats not the case one is actually a 250. Is there anything I can do to fix this or is it a problem that its showing as two of those cards instead of one of each card?

Funny you bring that up. not to be off topic, not sure if getting off topic is allowed but, I did have to do a fresh install to get everything set up to get my Physx card running again to play city of villains. I spent a while re-installing everything because i couldnt get rid of the newer physx updates that only have the updates and not the actual drivers for the card. After looking into the idea for quite some time I opted to go with putting the card back in because cith of villains only recognizes the actual physx card and not the physx emulator that nvidia has running on the new video cards. I have seen alot of posts against using the card and going with the physx enabled video cards instead but apparently because of the way the physx was designed in city of villains it will only recognize an actual physx card to do the physx portion because it was designed when physx was so new. Anyways in the midst of running into those problems it got me really thinking about getting more into BOINC and SETI alot more than I was at the time. I have been using BOINC consistently for a while but never really optimized my computer to crunch effectively. I decided to throw my older 8800 GTX back into my computer and see if I could set it up to use both cards to do CUDA and that brought me to this thread for more info on setting it up correctly. But I figured since I did do alot of gaming and had a diecent setup BOINC would be a good thing to run while I'm not gaming. Thanks again for your help.

Any suggestions for optimizing things to work as fast as possible. Any programs to lean out the unnecessary processes or optimize any other settings that you do use? I actually just did a fresh install on my computer so the overhead from any crap just floating around is gone I think I notice a difference already but, other than that any tips on stuff to optimize the computer for BOINC. I know eventually I need to or should get a dedicated machine but the one I have is pretty wicked so I will stick with it for now.

But said they had to make changes to their cc_config file. What changes need to be made to this. I am currently at work and am not infront of my client to see if it is registering both cards correctly. Should it automatically detect both cards and run good off the start or do I need to modify my cc_config file to make it function correctly. P.S. I forgot to add that I read your faq and the info in it on how to add certain programs to the cc_config file was just wondering if there were any changes that needed to be made to run the two cards. Would that just be the use_all_gpus line?

Another quick question I have is, with a program called game booster. Not sure if you are familair with the program or not. I used it while gaming and it seemed to help minimize the unnecessary running windows processes and other misc programs. I have been using that while running BOINC now and I wanted to know if you saw any problems using that program, do you see processes being stopped that are needed by BOINC. Sorry if it was confusing question but, just trying to optimize my computer for things like SETI especially while its not in use.

6) Message boards : Questions and problems : Running two video cards (Message 25343) Posted 11 Jun 2009 by Desiredconcepts Post: I was wondering if it is possible, or if it is supported yet to be able to run two seperate video cards. In my case a 250 as my main card for gaming and doing other tasks and an 8800GTX as a secondary to do CUDA work while I am using the computer. Is it possible to dedicate the 8800GTX to just CUDA work and nothing else? Thanks in advance for your help.
