I have been crunching boinc for a little over a year on a different account however I am new to primegrid.

I attached my computer to primegrid to use the its GPU but the workunits run for about 2 secs and then come up with a computation error. This has happened to every work unit that is sent to this computer.

The computer will happily crunch away at a few other projects including the Collatz Conjecture which also uses the GPU on the computer, so I am fairly certain that the hardware is not faulty.

I have tried to reset the project in Boinc and detach and re-attach the project but the results are the same.

Here is a link to the computer

http://www.primegrid.com/results.php?hostid=284325

The actual GPU in the computer is a Radeon 4650HD 1024MB.

There is plenty of hard drive space still available to BOINC.

I am not sure what I am doing wrong.

ATI (or AMD now) has removed OpenCL support from newer drivers for the HD4xxx series of GPUs. I believe that to run that series card with OpenCL apps you will need to run a catalyst driver somewhere in the 11.7 to 11.10 range (It has been a long time since I crunched with my HD4670, so anyone please correct me if I am wrong on this range).

Thank you for the reply.

I thought that it might have something to do with the opencl and the fact that AMD did stop OpenCL support for the 4600 series in their latest drivers.

But I thought that my particular computer would be alright as long as I don't update the drivers as The Collatz Conjecture uses OpenCL.

Which is why I am at a loss to work it out.

I did try an download version 10.2 legacy drivers from AMD but they wouldn't install at all. I am reluctant to uninstall the current drivers, as I can't remember what version they are and I can't seem to find out, but they appear to be working. (I can find the versions of the individual files but not of the overall package of drivers)

Collatz uses CAL, not OpenCL. Very different.

Up to 12.4 worked with my HD 4670.
