Can you add some "switches" that can be pressed while miner is running to change for example intensity on go or gridsize or some other things?
To don't have to restart miner..

just asking .. Roll Eyes

Yes, it is already on my list and will come in one of the next releases - some other user already suggested that.

On easy thing that you can do to improve you hashrate quite a lot is to improve the cooling of the GPUs. This can easily bring you additional 5-10% - maybe you already noticed that a cold GPU performs much better than a hot one.

Whilst this is quite common knowledge, I think it only really starts making a difference if your GPU is around 75-80C and above.
Don't think I've actually seen any performance degradation from a few degrees difference while one's cruising under 70 (where most undervolted Pascal cards should sit quite comfortably).

Hi dragonmike,

this is what I'm talking about - maybe that is because I do not really take too much care about the environment. This is my development 1070 in a big tower case - as you can see temp is 67°C and hashrate is around 2.2 MH/s - the miner running up for 60 seconds:

After some minute the temp is up to 69°C and the hashrate is down to 2.1 MH/s and during the same timeframe the CoreClk is down from more than 1.8 GHz to 1.75GHz:

Maybe I should take more care - have Fan on 'auto' in AB.

No this is a fair observation. If you start throttling between 67 and 69C it's definitely more sensitive than other miners/algos so worth pointing out.

I'll try setting a more aggressive fan curve, or pay closer attention to speeds between the cards next time, to see if there's any noticeable differences.
