Hi everyone, I'm having a problem with zcash mining lately, everthing worked fine for weeks, but recently every time In try mining zcash my miner crashes the hard way.. the entire miner freezes up after only 10-15minutes of mining, nothing can Bring it back to life except a hard reset. Ethereum mining works fine, zencash mining works fine but Zcash always crashes... Often it happens right after difficulty retarget. And Sometimes (not always) there is An error message "gpu 1 returned invalid data"..

Anyway I'm Running 5x 4gb rx 480, using a 4gb ram system.. the problem only occurs on zcash mining and happens on both windows 10 and Ubuntu...

If anyone could help me out that'd be great!
