I've just acquired a second Radeon HD 4850 and stuck it into my crunching box:
An Intel Q6600 with 2 GB RAM in an Asus P5B Deluxe, now with two Visiontek Radeon HD 4850's (previously only one).
No crossfire or anything is enabled, as I don't believe I want that, I just want two, separate cards, doing crunching (I do this with two different nvidia cards in my primary desktop and assumed I could do the same with ATI cards).
However the secondary display shows up in the drivers under the hardware tab as "Disabled Adapter", and I don't know how to enable it :/

You need to attach a second monitor or a dummy plug to activate the second card.

Bah, I don't have this problem with my nvidia cards...
Silly ATI.

Thanks for the help, connecting a monitor made it all better, some quick googling found how to make a dummy plug, so whenever I happen to get some resistors I'll do that.

Thanks a bunch Labbie! My crunching power has just doubled!

Okay, so far so good, all is well.

I have another question on-topic: once the card is detected as active, after booting, can I remove the VGA cable (to use on another machine for instance) ?


And an off-topic-ish question: Do I need to keep using the custom-added ATI apps or does this project support sending them out automatically via the stock BOINC client nowadays (using latest client)?

You need to keep it for now. Only a basic app is sent out currently. It was mentioned about setting it up to automatically send out the apps for ati and such, but no recent mention on that recently.

Yes you can. Once the card is recognised you can unplug it.

At the moment yes.

Travis' latest news post mentions getting all server s/w upgraded this week. Hopefully that includes the 'auto ati detection and proper opti app d/l' part
Then maybe my month-old 5870 can finally start crunching MW... though since I got it its been putting my Collatz rac through the roof.
Cheers,

PeterV

yeah for some reason MW will no longer crunch on my systems.
I download and install the app, verify that the .dll files are there...

It just tells me no ati device installed.
6.10.11.
And no I will not put an earlier version of boinc on as my main interest is collatz and it runs better on these newer versions.

You need at least 6.10.13 for all the new GPU stuff to work right. I'm running .18 on almost everything now without drama, so you may as well just jump to the newest public release.

Collatz runs better on .13+ than anything else because it will auto optimize for you (i.e. give you the best apps for everything you run, even if that's CPU + ATI + NV all at once).
