Mining require mor ram now?

a few weeks ago i was suddenly struggeling to get T-Rex to mine on my 1060 3GB cards. Cuda out of memmory error.
It was working fine before (HiveOS). I tried to upgrade to latest t-rex but still not working.

Card is working fine mining Vertcoin so card is good.

Should i use another miner? or is 3GB to little now?
