I found that the optimal configuration for l4 is when the coin is static and difficulty set to a larger value as the miner seems to restart less as @AppleMiner suggested.

Example

n=somename c=litecoin d=65536

Thank you,

I found that static litecoin works better. I will now play with the difficulty settings and update here.

Hi all,

I have a couple of Innosilicon A4+ miners (620MH), working fine, no complaints about payouts etc.

Would someone know the optimal difficulty to set for this specific miner for max profit?

Any tips welcome and much appreciated.
