It is working and fast but everything is working up to par.
Boinc downloads 48 task but only does the bottom 2 then get new ones so it stays at 48. The 3rd from the bottom start when the other 2 are reporting but never completes because when the new task are downloaded the bottom one start and the 3rd from the bottom restarts each time. I have set Milkway to no new task and it worked from the bottom up and every 4th task ran 1 second and got a error. I let them all complete then change it back to allow new task then it reported all the task and downloaded 48 more repeating what it did before. Also the status of the downloaded the 1st is ready to start and the 2nd is waiting to run(0.05CPUs + 1.00 ATI GPUs) and this repeats for all 48.
I will force the task to complete before the expire.


I was having the same problem. As soon as a new Wu was downloaded it would start crunching it and leave the unfinished one sitting there. When it restarts the unfinished Wu it restarts at 0%, wasting time...

Installed 6.6.36 over 6.10.4 and removed the
<coproc>
<type>ATI</type>
<count>1</count>
</coproc>

from both places in App_info.xml.
When restarting the new boinc install all three machines errored out. Had to reinstall Boinc6.6.36 using the repair setting.

Working good so far for me. Runs three at a time now. Also no more errors.


Vista64, HD4870, Boinc 6.6.36(64) ,Milkyway 0.20ati(64)

also on two other machines

Winxp(32), HD4850, Boinc 6.6.36(32),Milkyway 0.20ati(32)

I have a couple boards that have extra PCIe slots. What do I need to do to get this to run on both cards at the same time.

No crossfire right?
Do I need to have a monitor pluged into the second card or use a VGA dummy?

So far I have two 4830's, 4850, and a 4870 running with Winxp32 8.12 19b.
I have two more 4850's in the mail. Waiting to get a 4890 for my machine...

4830's seem to be the best bang for the buck ($89.00). Both of mine overclocked to 650 (max) and run at 51c...

They all run quiet under full load.

Does the GPU App work with Vista32 or Vista64 ????

Does CPU speed matter when running Gpu app?
Does 1 to 4 cpu cores make any difference while running Gpu app?

Does this look right?? Its putting out 4 at a time in just over 2 min.
No other projects running.

Would a 4850x2 work with the Gpu App? Use both cores?
