Thanks for the additional feedback. We have reviewed the software, and while we have not been able to reproduce the problem you are seeing, we believe that we have found a function that could potentially cause problems with the Maths test on systems with 8 or more physical CPUs (= #CPU packages x #CPU cores).

We have produced a new build of BurnInTest and believe that this will resolve your issue. BurnInTest V4.0 1031 can be downloaded from:

Please let me know whether this corrects the problem.

Best regards,
Ian (PassMark)
