A while ago I wrote a CUDA implementation of a subset of the Memtest86+ 
algorithms,to test the reliability of the consumer GPUs used by our 
distributed computing project, GPUGRID. You can get them here:

That said, we never really used it in anger (most of the stability 
problems we were having turned out to be due to 'factory-overclocked' 
GPUs) so YMMV.
