Ive got a bit of a problem

I have 3 295s installed in my Classified 4 Way while i run it in on air but Boinc is only detecting 4 CUDA devices

it will only crunch 2 WUs the rest error out

running Boinc 6.10.18
nvidia 195.62 for Vista 64

any ideas?

Hi b@llzilla, I don't know if it will do any help, but when i tried putting in a second graphics card, I had to edit the cc_config.xml file (or create it) in the c:/programdata/boinc folder and put in a few lines like this:

<cc_config>
 <options>
  <use_all_gpus>1</use_all_gpus>
 </options>
</cc_config>

And go to Advanced -> Read Config file.

With regards to the cards erroring, I can't help there. That could be caused by many things probably. They are not too hot are they?

just an update on this problem

lotsa problems, but its all running now

First up, to get the EVGA 4WAY Mobo working with 5 GPUs I had to go into bios and set "low memory gap" to "3G" instead of "Auto"...dont ask me why, but it worked :)

Next I had to roll back my drivers to 190.62

Finally in order to get BOINC to see the gpus they had to be active in nvidia control panel... enabling sli on my 295s allowed boinc to see 4 gpus, enabling physx on my 285 allowed boinc to see the 5th

Have you tried the 196.21 or the 196.34 drivers?

im back to trying 196.21 now... so far so good
