New to mining! Ethash miner not using all GPUs

[Bnmakr1]

First time poster, long time reader.  I tried a quick search but couldnt find my answer. I have 4 1060's using Ethash miner. It appears it is only registering 3 of them. I am getting about 55mh currently. Any thoughts how to get my fourth GPU involves?

Ensure that your 4th GPU is properly installed and detected in your system, if your using windows, check this in your device manager, if it doesn't detect or has an issues it could be the culprit.

Try :
1. Move to other PCIE slot.
2. Check or Change your USB Riser.
3. Check Power from/ to USB Riser.
4. Check Software Driver.
5. Check your Windows.

good luck
