I bought a card Msi armor rx570 4gb oc at the beginning of the week. My problem is that when I use Claymore just after installing windows 7.10 (tried on both, both are experiencing this problem) it works, while loading shows that my card has 4gb blah blah blah. Everything is beautiful. Until I turn off the program or lose power. At startup Claymore starts to load but shows that my card has only 3gb. Then followed by a frozen message "the program stopped working" reinstallation of drivers nothing gives. Downloading Claymore also does nothing, the only thing that helps is to restore the system to a state immediately after installation, or just restart the system. This is very annoying because when I want to change the quit currency or change some options. Every time I shut down the program I am forced to restore the system.
lets go slow
how many card on the rig?
is the rig mixed with rx 470 to rx 480?
did you try mining zec with claymore's zec program.
is it a new card ?
did you flash the card?
I have seen people say some 4gb cards show as 3gb and won't mine eth
If you have 2 of these cards does one work and not the other?
did you flash the card?
btw I only use 8gb or larger to avoid this issue.
