What GPU are you using? cause some of them use Overclock setting as stock, and care to post your miner .bat settings so I could see what you have set, cause I believe there are some stability commands to type in depending on your card.
Here are my settings and afterburner setting. by the way I have also edited the bios.
4 Asus RX480 4gb
.bat settings
setx GPU_FORCE_64BIT_PTR 1
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100
