I have been able to continue mining after Epoch 382 with full rate:

Simplemining:
--algo ETHASH --pool poolurl:port --user wallet.rigname --pass x --apiport 4444  --4g-alloc-size 4080

HiveOS:
Add in extra parameters : --4g-alloc-size 4080

If 4080 doesn't work try 4076 you will loose 2Mhs.

Enjoy full Mhs
