For some reason I am having a ton of issues with MSI 390x on 11.x-12.3
I keep getting crashes and error messages about the 'GPU blocked from receiving data' in windows and 'returned faulty data' in miner. No idea why. 15.12 drivers, Win 10 x64
I have the MSI 390 (no X) and W10 x64. For me 15.12 works although gives pretty less sols than latest drivers.Currently using 17.3.1. Moreover, when I've got "returned faulty data" has been due to the voltage is not enough (trying to undervolt the card, specially the AUX vol, or setting the Memory Clock too high).
Also you might ping the pool's server, opening a Command promt and running for example:
ping zec-eu.suprnova.ccyou'll see if average is too high (above 350ms).
Regards.
