found a work around, but it's not all that practical....  No "Join this team" link, looked up a random team with the link, copied the address for the link and changed the team id to that for Crunching@EVGA and it went through....

I've just added Collatz Conjecture project but my GPU usage, % is just ~87 instead of 99. I guess it's because of my rig's Win7 64-bit o/s.

 

This is probably normal. I have not tried Collatz recently but some project applications use the GPU less than 100%.

 

I'd performed some tinkering of Collatz Conjecture's app_info.xml (see below search for those parts which are bolded in blue) after reading http://boinc.thesonntags..../forum_thread.php?id=3 (this thread) about "Optimized Applications", I've managed to get my GPU usage, % up to 99.

Take Note;-
app_info.xml,  collatz_2.05_windows_x86_64__cuda31.exe & cudart32_31_9.dll are copied together into boinc.thesonntags.com_collatz folder whereas L13 I8 S0 is the secret recipe and the full explanation of its syntax can be found in the readme.txt for Windows 64-bit o/s.
