Hi There,
I have a 4GB NVIDIA 1050 ti graphic card, just tried 1.18a 1.19 lolminer on ubuntu 20.04 , get  error below

Pre google search I have add --4g-alloc-size 4076 --4g-alloc-size 4036 --4g-alloc-size 4128 in lolminer command line , none of them works

./lolMiner --coin ETH --pool us1.ethermine.org --port 4444 --user XXXXXXXXXXXXXXXX.YYYY --4g-alloc-size 4076

What am I missing for here,

Thanks alot for any help
