I want to start only cpu,which configurations to use?
Loki wallet gui don't sychronise.
What configurations for xmrrig cpu only?
Loki mining is only CPU currently. As RandomXL is a new algorithm there is no GPU support as of yet.
You can always join the mining telegram to speak to the big commuity of Loki miners, they would be your best resource for information.
