Mining with a GTX 1060 6GB.
Mining for about 7 hours on default settings, got 1.17 GRLC from ButterPool in my wallet so far. However last payment was 2 hours ago, not sure why, so I switched to garlicsoup just now.
Average hashrate is 243 KH/s, I think I get 253-257 KH/s with --lookup-gap=2 but it seems to get invalid blocks far more often.
72-74C on card, just left everything on default as I'm not taking this too seriously.
Ambient temps are 24C.
That seems a very low reward.
Try
https://garlicpool.org I get about 1.4 Garlic an hour with 2 x 1080ti and my hashrate is about 800 total so I would expect you to get a 1/4 of the reward I do per hour - so about 0.35 giving after 7 hours 2.45.
Figures are rough and you should check the luck of the pool you are on and also consider if the reward is PPLNS you will receive lower rewards for the first few hours on the pool
Good luck
