I have Tahiti and Fury GPUs. They randomly finish a task in an hour, or not at all, no % GPU usage, just sit there. Not sure how long I should leave them. No CPU being used either. I'm now trying 8 at a time on the GPUs so they can work on another when one has dozed off. The cards are NOT incompatible, because I have successfully finished many tasks on them all.

Should be a problem with multi-GPU, the app doesnt have multi-GPU support, there must be a fix somehow but dont know yet. Excluding a card doesnt help either because you have the same multi-GPU setup. Its a real BOINC client issue, need one GPU WU on every card separatily.

You have a point there, my triple GPU machines are the two failing. The others work fine, they have single GPUs. I couldn't put my finger on it because I was looking at card models instead. Is there some way you can prevent them going out to multi GPU setups? Inform the user, etc? They seem to work then mostly fail or sit idle for ages. By the way, I didn't get an email to inform me of your reply.

Can you tell me the address it will be coming from please? I can simply add a whitelist exception like "microsoft.com" - for now I'll assume it's my-firewall.org (which to be fair on my ISP filter does look dodgy!)

I'm confused now. Earlier you said "Excluding a card doesn't help either because you have the same multi-GPU setup", but now you are suggesting (I think) I can keep SRbase off all but one GPU and it would work?

Cool! That seems to be working. Although I changed it to: <exclude_gpu> <url>https://srbase.my-firewall.org/sr5/</url> <device_num>2</device_num> </exclude_gpu> <exclude_gpu> <url>https://srbase.my-firewall.org/sr5/</url> <device_num>1</device_num> </exclude_gpu> Because the project is attached with https, and it doesn't seem to take two device numbers in one instruction.

You can try this...
