It does not matter which MoBo you get.
You don't want to use either Crossfire or SLI, just the vid cards.
The whole idea behind Crossfire and SLI is to combine two or more vidio cards into one device to improve the output.
But if you do that, then the drivers only see one vid card and hence you can only run one client.
Not the one client per card you could if Crossfire/SLI was disabled.

I run multiple nVidia cards on an ATI MoBo with no troubles.

Luck ......... :D

OK :) Assumed that as it's a ATI mobo it's assuming 2 cards are therefore ATI :) so wouldn't recognise 2nd NVIDIA card! oh well, was just a thought ;)

Hi susato

I'm having similar problems. Did you ever find a solution?

After uninstalling Nvidia drivers and on reboot, kill the "found new hardware wizard.
Assuming you have the executable Nvidia drivers (NVIDIADisplayWin2k(178_08)Int.exe or some other version) somewhere on a HD or memorystick, doubleclick it and run through the installation.
The GPU2 client should be able to run on both cards whether you choose to reboot as instructed or not.

Happy folding!

Thanks for the followups Christopher and ei57. For now I'm still running a single card on that system, with a classic F@H unit running at around 60% of a core to occupy the rest of the dual-core CPU. Just haven't had the time to play with it again. I may have been contributing to the problem by failing to reboot Windows after every hardware change, driver install or driver uninstall. (Linux and OSX don't require this but apparently it's standard operating procedure for Windows, as ei57 indicates above)

ei57, do you recommend using "driver sweeper" or any other helper program for uninstalling?

I've only used the "Add or Remove Programs" in XP for uninstall and rebooted. I added a second gpu in this PC about a week ago and if my memory is correct, I didn't reboot after driver install until today. When installing new drivers, I clicked "yes" to overwrite old files. There should be no need of other SW to clean out old mess.

You will probably have to set up the display and extend Windows to the second gpu. I don't remember if I had a dummy connector attached to the second card, but I think not.

Remember to add -gpu 0 and -gpu 1 in Additional Client Parameters in the Advanced section in config.

I've finally sorted out my machines, the problem was from a competely unexpected source. Take a look at this thread http://foldingforum.org/viewtopic.php?f=38&t=6886, it may give you some inspiration.

The link was to a topic location from 9 or more years ago. It probably has moved or been deleted since then. Most likely the information is no longer applicable to more recent hardware or software.

Another possibility: When moderators merge topics of the same subject, one threadID is retained and the other no longer exists.

When I merge topics, I do consider that process and do make an attempt to aim known references at the persistent topic number. I don't guarantee my efforts are 100%.

Is there an open ticket to correct this at phpBB?

Given that the EOL for 3.0.10(the versioning that the installed themes have) was November 2015, probably not. :roll:
