i have 3 farms on rx570 one of them is with just 1950 mem (thats on pc that i am gaming on)
when it switch algo on 1.6.9 i get
[2018-10-28 13:55:50] pool_have_job: Pool sent a new job (ID: ezf4jX58YooLZjABQrqsX7CgVRKD) [haven]
[2018-10-28 13:55:53] compute_error_alert: Too many compute errors on GPU BUS_ID[2] (15)

it spams errors on all cards no shares on pool and after it switches back to v8 it starts mining again on fast algo its the same pattern

with --resetmineronalgoswitch it works fine on 1.6.8 aswell
