It's normal operation for BOINC to only use the better performing GPU if a system has two different GPUs types.

Have you tried using a cc_config file with use_all_gpus  set to 1?

It's been a few years since I did a comparison, but the GW CPU tasks offered significantly higher credit than the Fermi ones on my intel/win10 boxes.

Yes, 1000 versus 680 credits.

As I did mention, it's credit

As I did mention, it's credit per unit of time that would be the important metric for someone trying to squeeze every last ounce of RAC from the CPU cores.

I don't run CPU tasks but the last time I noticed (admittedly some time ago), it was possible to get nearly 2 GRP tasks done in the time to complete a single GW task.  It probably differs with different architectures so Tom would need to do a comparison on his host to be sure.  In the end, it probably wont make a great deal of difference.

Cheers,
Gary.

Joe,

If you check the first 30 odd lines of your Boinc log after you first start up Boinc it lists the available gpu even if you are not using them using the "use_all_gpus" parameter.

I am reporting that when I install an Rx 5700 GPU and an Rx 580 on the same system I get one GPU or the other GPU but I can't get both to be listed at the same time.  Don't get me wrong, the non-listed gpu is still functioning as a monitor driver.  But not as a cruncher.

I think I have replicated this across both Linux and Windows.  So something about the two versions of OpenCL don't play well together.

It would be really nice if we could run heterogeneous Rx video card setups.  It would make it cheaper to set up 5-7 GPU rigs with very high production levels (aka RAC).

It would also make the top 50 producers list even more production heavy.
