I need help on starting with 570 4gb

Hello!

​

I just started on a Side PC with a 570gb 4gb, my only 2nd card, and want to put it in Rvn.

​

Went for 2miners, downloaded its setup, put wallet, etc.

​

But im getting 15mh speed which aparently is great, yet im getting way to lowers accepted…

​

On the miner screen there is no error or nothing..something i should look for?
