I'm having a serious problem, All 8 of my RX580 8GB goes to 0.00Mh/s after an hour or so mostly when a new DAG is being created. It started happening only after I updated to Phoenix miner 5.2 (I am on Nicehash, Windows 10, AMD driver 20.7.2, also tried 20.9.2). My rig was stable from a month before updating Phoenix miner. LOL miner works perfectly and TRM also works perfectly. Please Help!
Using Windows 10 1909, AMD 20.11.1 driver, PM 5.2c, nicehash, RX 580 8Gb cards - all fine. Miner works many hours without any problem.
How can you be on PM 5.2c ?, Nicehash software only updated it till 5.2b. Also, can you please give some more details about your system: like the motherboard moel, Amount of RAM, Virtual memory and settings like PCIe link speed, and if you're using Overdrive N tool or MSI or both?
I'm didn't use Nicehash software. I'm use PM miner with manual settings for nicehash pool.
Virtual memory is 8gb * amount of cards. I'm use modded vbioses.
You can update PM in nicehash. Just find folder with PM in nicehash folder and replace files.
