Hi there,

I have an onboard HD3300 GPU and a pcie HD5450 GPU, both are enabled and visible by boinc but only the primary one (i can switch between these, restart my computer) will work at a time. I would like to have them both work simultaneously of course.

I have followed the instructions here: "http://boincfaq.mundayweb.com/index.php?language=1&view=471" to modify the config file but it still hasnot allowed me to make them both work at the same time.

Here's the event log:

If there isn't a dummy VGA plug or a monitor attached to the not used GPU, it won't be detected. But then, not sure what project or projects you run, but the AMD Radeon HD 3300 can't be used at (m)any projects anyway, mostly because it will lack the necessary workgroup size. Since that is something internal in the GPU and cannot be upgraded through software or drivers, you have to wonder if it's worth it to get it to work.

Added to that, most projects use OpenCL instead of CAL, and neither of your GPUs shows that it's OpenCL capable. That's because the HD3300 isn't OpenCL capable, but the HD5450 is, or should be.

Added to all that, I don't know what Catalyst version the driver 1.4.1734 is, but if it isn't one downloaded from the AMD driver site, then go there first and get the latest available, or at least the 12.2-12.10 version. Don't get 13.1, it'll have a bug in that breaks OpenCL capability on a lot of systems.

It's also a good idea to completely clean out the old GPU drivers before installing the new ones.

Thank you for your quick reply

there is at least one screen plugged in and used for both so that isn't an issue

I understand that, I've been crunching collatz mostly on the 5450, there was another project too that work on this card but I haven't added the project to this rig to see if it'd work. (this is my older rig that im just setting up to do stuff because, science!)

you are right, i didn't even realize that, I believe that is the legacy driver I first installed or the onboard. I installed the one for the 5450 on top of it and its been working fine. I will preform a clean installation and get back to you.

If your GPU is detected by BOINC but not used, you need to tell BOINC to use all GPUs. That's done by creating a cc_config.xml file in your BOINC data directory and inserting the <use_all_gpus> option. How to do that is described in the BOINC wiki: Client configuration.

I bought a new Nvidia gtx 650 ti and ive got both that and my onboard working now in the same rig. Thank for the help! I figured out the trick in the settings.
