I have one box with a GTX260 which I use for Seti. I recently, well yesterday, installed a 5970 as I want to lift my MW performance a little.
I was running BOINC 6.10.29 happily until I installed the drivers for the ATI card.
All I get now is the message "Connecting to localhost" in the manager, with the client MIA.
I downgraded to 6.10.24, then 6.10.18, in case that was the problem but still the "Connecting to localhost" message.

MSI Afterburner shows all three GPU's are present, and I am running Windows 7. Is there some BOINC config file I need to modify?

EDIT: Given the ATI driver seems to be the cause of all my problems, I should say what it is, doh. Cal 10.1 Beta.

OK I have found the magic combination, finally!

BOINC 6.10.29
Cal 9.12 hotfix.

I now have Seti on the GTX260, and M@H on the 5970.
I did have to detach and reattach to get it all going.

Lets hope it is the same arrangement when Fermi comes out.

So what your saying right now is that you have an ATI and nVidia card in one PC and you can use both for computations?

That's exactly what I am saying. I am using the NVIDA 260 to crunch Seti and the ATI 5970 is crunching Milkyway, on both GPU's.

It was a concern for me because, one of my personal goals, is to have every project I start go over one million credits. So no GTX260 no Seti.
I was also, using MSI Afterburner 1.4.2, able to overclock the two 5970 cores, but leave the GTX2620 core alone.

Now that the whole thing is stable, I will, tomorrow, max out the system by adding another ATI 5970 to the mix and see how we go.

That is interesting, because iv got an 8600GT card in the PCIe slot and an integrated HD4200.

David, which motherboard are you using to have 3 PCIe slots? I know there are several, I'm just interested to know what you've got. Regards....

5970 has two GPUs, but use only one PCIe slot.

On two of the boxes I am using Asus P7P55D Deluxe, and in one the Asus p7P55D Pro, which is the non gamer version of the above. They run the 1156 socket chipset I use.

The Pro version is the oil cooled one, which will end up with the four 5970 GPU's oil cooled and a Fermi GPU also oil cooled. According to my supplier the Fermis are buggers for heat. Even the single entry level GPU will run 200 watts.

I am about to install the other 5970 now, then on Tuesday we will do the conversion to oil cooling as the blocks for that have also, finally, arrived.

BTW: When I was cooling one of the the twin 295's I had in the box, with air, they ran in the high 80's to max at 91 degrees. When I converted just one card the temp dropped to a steady 38 degrees on that card and its neighbour dropped to low 80's. An eye popping difference I thought.

David, what liquid cooling system do you use?

There is a review of the 5970 blocks I will be using.

This is not the cheapest company to buy stuff from, but I like the security of using the best metal fitting etc that I can find. There is a serious amount of hardware depending upon it in my machine!
