Why just stuck 2.4 gb memory? how the settings in the command to increase Ram is more widely used? Help !

did you set "minermemory"?
anyway, increasing miner ram over 1gb is (again) giving very little hashrate increase and (again) much higher risk of orphans, so just avoid it.
how to set minermemory ? i try command -minermemory=2 -genproclimit=4 on debug windows not work " methode not found ( code -32601 ) "
