As the DAG gets larger there is a drop in performance. Depends on the GPU and OS as to what the drop off points are but this was the same type drop that occurred for 3GB cards before the DAG became too large for them to work at all.

I think I understand why above issue happening;

ETC Epoch #302 = Dag Size 3.36 GB (Drop Hasrate when mine ETC)

ETH Epoch #294 = Dag Size 3.3 GB (No Drop HashRate to mine ETH)

Hello,

Mining OS : SMOS

Tested miner softwares : Claymore 15 / Phoenix 4.7x 4.6x

Algo : DaggerHashimoto (Ethash)

Coin : ETC

GPU's : GTX 1070 8GB

Ram : 4GB

Storage : 120GB SSD

Issue : For a few days my GPU's has lower hashrate 1 - 2 MH/s by GPU when mine ETC .
( 12-15 Mh/s hashrate drop for every 12x GPU rigs ) No problem on ETH

I didn't change anything about Hardware / software / OverClock settings.
Does anyone notice a similar problem?

My AMD Rx GPU's It was not affected
