Hello,

I am using EWBF's CUDA Zcash miner Version 0.3.4b to mine ZCASH. When I open the miner my first hashrate is good: ~ 2550 sols, but after 30 sec the hashrate drops drastically to ~2200 sols

This is my batch file:

miner.exe --server eu1-zcash.flypool.org --user "mywallet".Miner01 --pass x --port 3333 --cuda_devices 0 1 2 3 4 5

6 x MSI AERO GTX 1070, AsRock H81, Corsair AX1200i.

MSI Afterburner settings: 70 power limit, 150 core clock, 600 memory clock, 75% fan speed.

Does anyone know which would be the problem?

Thanks!

Fail to plan, and you plan to fail.

Your temp limit is 70, as cards hit 70 degrees they throttle to keep temps stable, so performance reduces.

Should I increase the temp limit? It will also increase your power limit.

You should increase the limit of both.

No the two can be separately adjusted, just tick the chain button in MSI afterburner, increase the temp limit and try to lower your power limit your desired hashrate, the trick is a trial and error depending on your taste and to your acceptable power consumptions.
