When you are benchmarking your cards, it can happen that some mining clients won't report the speed. In this case, the result of the benchmark for this mining client and algorithm combination will be Failed (Missing hashrate). You can wait for the benchmark to finish and when it does, you will have an option to rerun the benchmark for the failed algorithms.
The most common reason why this happens is that mining client didn't have enough time to start mining on your setup.
If this is continuously repeating, try making a new benchmark with longer benchmark duration.
If hashrate isn't detected after reruning it in slow time, check console output while benchmarking. You can send us a screenshot and we will help you resolve the issue.
