Did someone try this tool on RX560 cards? With the custom bios i am getting 14.8 MHs per card on eth/etc... What could this tool do?
If you read through the thread (at least partly) you get an idea how you can add a few percent to your hashrate using this tool.
In general you can expect to gain a few more percent by fine tuning the public modified straps for Polaris cards.
