Constantly getting "GPU #1 returned incorrect data!" on v12.0
v11.1 works fine.
Virtual memory size = 16Gb
SET GPU_FORCE_64BIT_PTR 1
SET GPU_MAX_HEAP_SIZE 100
SET GPU_USE_SYNC_OBJECTS 1
SET GPU_MAX_ALLOC_PERCENT 100
SET GPU_SINGLE_ALLOC_PERCENT 100
are set
UPD. In my case they are set via SETX but I think it doesn't matter.
Same here as well. Gpu 1 incorrect data. 7970. Finally pulled the card and put in a 390x. All is well. Funny was that after running v12. That 7970 does same now on v11.1. Think it wiped out my card. Def some bugs in the new release. Save yourself some headaches and move to v11.1 if you can't get stability. At least it will run more than a few hours. Also same rig when it would drop to 0 hash on a different random card before replacing 7970 it would start getting socket errors. Then pc was no longer accessible via team viewer. Had to manually reboot Computer. Great effort claymore. I am getting over 400 sols on 390x. Those seem to have no issues running v12.

Same here with my 7990. I reduced mining intensity from 5 (default) to 4 and seems the issue is solved.
