What is the makeup of the rig you are trying to benchmark? Does it have all the same types of cards? (e.g all 1070s) Are you giving the benchmarked profile a new name? Are you benching a single card, or trying to do each one individually?
TLDR first: Various Rigs. Single Vega 64 for now. Clone of AMD Default. Single Card Benchmark /w both Single Algo & Entire Series Algo tests.
Various rigs in various configurations, always a single GPU under a cloned profile of either the AMD or Nvidia default profile (so I don't mess up other profiles). Specifically, the one I'm trying to do the past few days is a Vega 64 card in both a local and remote configuration on a windows 10 pro system, both pretty much configured minimal. I've even reformatted once on the test machine (and switched mobos in the process), but I don't want to do it on the one I actually have dedicated to monitoring my other systems. But, as I mentioned before, I can switch one of my Nvidia remotes from my dedicated monitoring system to the test bench remote and it does the same thing (I don't have a spare Nvidia card to actually toss in the test unit atm). Doesn't matter if I'm doing a single algo bench or an entire series of algo's.
If you were to only select one algo to benchmark, run it... can you save it to the profile?
