hi. I've recently had an issue with my phoenixminer 5.1c. I have 6x 5700XT with  20.3.1 driver and having no crash in the asia1 ethermine pool. my cousin lives near me with the same mining rig and the same pool. my rig was hashing very well until the last few weeks my stales are rising up and my average is going down as I have  50 to 30% stale shares now! while my cousin (with the same net and the same pool and driver) has not!He has under 5% stale share with the same phoenixminer 5.1c . what's wrong?
