IT WORKS

with 4GB
But now there is an othher problem. Using 3 GPUs all of them are working, as long as I put the next one - nothing works.
All GPUs are in dev. manager -OK
Claymore shows also 4 GPUs
but then there is an error: cannot create DAG on GPU
GPU 1 failed
then same restart, and next time GPU 3 failed, next time 2 or again 1.
Are even 4GB not enought for 4 GPUs?
