xmr-stak runs but the hashrate 0 is constantly
confirmed neither xmrig-amd nor xmr-stak are working on a 6870 with CN/r, didn't plug my 5850 in to check it. As a test, Lyclminer 0.2.1 was working on the 6870, but that isn't the algo you're after. (lyclminer is for lyra2rev3) xmr-stak runs but the hashrate 0 is constantly
