RE: I'm wondering if there

I'm wondering if there is an incompatibility of that driver with older Nvidia GPUs.

ie, it won't allow older GPUs to run alongside of the 1080

I just checked the nVidia site. Although the "Supported Products" tab for the 368.25 drivers only list the geForce 10 series, with 1080 in the list, the release notes Table 3.1 (page 34) seems to indicate it supports previous series as well:

If you try placing the 900s

If you try placing the 900s series in the download driver section, you get the version before 368.25 but it may very well be that the new driver does support the older GPUs

But I guess what I'm really asking is can you put both GPUs in the same computer and have them both run?

Which PDF / page are you looking at? I didn't see one on the GPUPRO beta page.

Oops. I was looking at the driver page for current options in particular my Pitcairn. They had a rather lengthy PDF file for Ubuntu 15 which I think also applies to Ubuntu 16.

Something I saw by way of

Something I saw by way of release notes a few days ago kind of said that 368.25 was released with less testing than a fully supported production release should have to support initial 1080 shipments, and that if one did not have a 1080 one was probably better off not using it.

That is utterly different from stating that a computer with dissimilar GPUs won't work.

If this question is still pending in a couple of weeks when I hope to have a 1070, then sometime in the testing I can put in a 750Ti with the 1070 for a cycle just to check.

But I would be very surprised if mixed GPU machines don't work, and suspect more likely than not they already do with 368.25.

EVGA 1070 FE pre-orders are live on Amazon. Probably won't be purchasable by the time you click this:

Regarding GPU mixing on the

Regarding GPU mixing on the same machine, does anyone here know whether it works to have an AMD GPU and an Nvidia GPU on the same PC and have Einstein running on both? Would BOINC have to be clever enough to download both CUDA and openCL work?

My guess is that this does not work, and perhaps the conflict is even more fundamental than running Einstein jobs, but I don't know and would value accurate information.

I failed to think about this point in my earlier comment on getting a 480 to try, which I still well may do, but this consideration makes it seem likely to me that putting a 480 on a PC would mean dedicating that PC to AMD-only. For some months now I have been running all three of my GPU PCs with two cards, so this is something of a consideration.

Yes it will work(*), there are some examples

and

https://einsteinathome.org/host/12175545/tasks&offset=0&show_names=0&state=4&appid=29

good luck!

edit: (*) in theory.

Arch, You can run both

Arch,

You can run both AMD and NV in the same case, but there is a specific order that the drivers have to be loaded.

That being said, that cavet is only for Pre 10*0 GPUs.

I can't speak for 1080 or 1070. My experience has shown that the 1080 doesn't want to work with any previous generation NV graphic cards.

Others might be able to get it to work, who knows.

Could you tell us more about that experience?

At this moment Dave's machine is the only one I'm aware of running a 1080 here, though I'd not be surprised if there are others.
