Re: NVIDA & ATI (in the same system)

And for those of you that are using a version 6 with no issues, I'll tip my hat.

As you return 11k results per day you have much more experience :) But I'm a little lazy and don't like to change things that are working. And 6.10.58 works fine fore me. Zero errors or invalids. At next instalation I'll try.

Re: NVIDA & ATI (in the same system)


Running ATI and Nvidia together on the same machine might work but it's probably not worth the effort. The drivers seem to not play nice with each other.


This is what I thought the answer would be, but I was not sure.

Thanks for all the responses.

Re: NVIDA & ATI (in the same system)

<comment>
Managing multiple-devices for a resource-type is the job of the OS. In the audio area, the (Windows, and Linux) OS has an effective mechanism to manage multiple audio-devices. I'm not aware of an equivalent mechanism for visual-devices. The OS manufacturers may not have seen the visual-part coming which was quite understandable then, but clearly times have changed. We may thus have to tell the OS-makers for that.

Re: NVIDA & ATI (in the same system)

I am currently running 2 GTX 580's and 2 HD 7770's in my System (ASUS Rampage III Extreme, i7 970, Corsair 1200 psu, 12 GB ram with Windows 7 64-bit).
I am using 7.0.28. I am now going to see if I can run an app_info.xml to get them all to run multiple GPU WU's each...

Re: NVIDA & ATI (in the same system)

Hello HammerON,
Just a cautionary warning. BOINC is developing in a direction that deprecates using both ATI and Nvidia in the same system. You can do it now, but that may change sometime in the far future.

Re: NVIDA & ATI (in the same system)

To expand a little, that what is now being developed in work controls will not take account of ATI/NVidia mixes. The design is in early form and allows e.g. to config how many jobs are run on a type of resource [e.g. X of CEP2] which many have wished for for ages [long before CEP2], either CPU or GPU (And this *IS* WCG/Berkeley supported.). How that will affect the future of app_info? (There are several lines of french for that, depending on the POV).

edit: Oh and when? Like Lawrence said, in a [unknown] future. This will require a new client to recognize the configuration instructions.

Re: NVIDA & ATI (in the same system)

I inadvertently omitted my "cc_config.xml" the other day from BOINC (7.0.38, x64), and HCC ran fine on both an AMD HD 7770 and an Nvidia GT 240; I didn't even know it would run on a card that old. But it was slow on the GT 240 of course; 26 minutes instead of less than 5 minutes on the 7770 with the double work units.

But I will happily give that up for the ability to run more than one work unit without an app_info, when that time comes.

Re: NVIDA & ATI (in the same system)

I have also heard that Windows 7 works much better then previous versions as far as mixing the two brands in one system. I have not tried to do it since Vista was released, so YMMV.

Yes, XP is OK and Win7 is OK with mixed cards. But Vista does not like it at all; it has something to do with the driver model they adopted in Vista.
