i got problems
some of my pc when i mine monero with claymore 8.1 win 3-4gpu 280x they go shut off
i did clone hdd with 8.1 to others hdd
my power is 2x800w and other rigs is 1250
2 of rig working good with 4 gpu from my 8 rigs
help me
20gb virtual ram
alloc max 100 done
look into windows..i think it goes to sleep or turn off hdd after 20min or so..set it to always on
and look at gpu temps..pc also turns off when gpu is overheating.
also check the voltage in your outlets..if you are living in a country that have 240VAC and the voltage in your outlet is ~190VAC some pc may go off unless your power supply is 100 - 240VAC rated.
before windows my rigs worked perferctly on linux and mined alot
i got this problem on windows
have 14.7 drivers
only 1 rig now working good - others goes off always i will try some tips from claymore topic
