a lot of possible cause, might be a clock issue, overheat, risers, Power supplies, etc

Are your GPU's modded?

Start with a default command lines and default clocks excluding those above

check also your miner logs and windows logs thru event viewer

you may get a hint what would be the cause

in windows type eventvwr\windows Logs\Application

im check windows logs
