3x 5850. Only first one recognized by BOINC

post #1 of 8
Thread Starter 
Win7 x64. 11.4 driver.
I used to have only one 5850. Got two more today, and installed it.
BOINC and the Bitcoin miner poclbm says I only have device 0, which is the 5850.
GPU-Z, MSI AfterBurner, and Windows Device Manager all shows 3 GPUs installed.
AMD Vision control shows I have 9 available video outputs, which is correct, 3 for each card, total of 9.

Went into CCC, it says that CrossfireX is not enabled, because I did not install the link cable.
My motherboard is the older MSI K9A2 Platinum with 790 chipset. I don't even know if it supports crossfire.
Even if it did, the Sapphire 5850 Xtreme card I have only have 1 Crossfire link on top, NOT two. So I don't see how I can connect all 3 cards together.

What is causing BOINC and bitcoin miner poclbm to only see device 0?

I thought dummy plugs were only a problem with nVidia 8 and 9 series cards, and were later fixed with a new driver.
AMD is still in the dummy plugs age?
Can I make one out of DVI to VGA adapter?

Shut down boinc. Make yourself a cc_config.xml with Notepad with the following in it:

<cc_config>
<options>
<use_all_gpus>1</use_all_gpus>
</options>
</cc_config>

Put this in your Boinc folder. Start boinc and if it worked correctly you'll get a message saying use all coprocessors in the messages tab.

By BOINC folder you mean the BOINC program or the data folder?
I placed it in BOINc program folder, it doesn't work.
Then I placed it in BOINC data folder, and it doesn't work either.

It goes in the boinc data folder. And make sure you name the file with the .xml extension. You might have to enable "veiw extensions" in the folder options.

Weird that it still won't work. This thread shows you how to do it. But its the same thing I already told you.
