So recently I tried mining using nicehash quick miner. I see the miner is mining ethereum. They also have different modes of the miner. When I select the lite mode my hashrate stay the same 40mh/s and card is pulling only 100W. My questions is can I copy those settings and use them to mine ethereum directly via gminer or some other miner. I guess it's about the gpu clocks both memory and cpu and maybe the vcore?
Learn how to optimize your cards and don´t how to copy some settings.
Use Msi afterburner, set a low fixed voltage for gpu, overclock your mem. Try something and understand what the hashrate do if you change the settings. Understanding something will help you in the future if you have problems.
