What coin are you suggesting to mine? As far I can see everything will go so down that we but GPUs for nothing...Waste of money, we will never be in profit, at least I know for myself. I'm mining from 2. January 2018.
All the best

As far as I know, it still possible as of today, some users were able to solve this with the ff:

it's a problem with Windows 10 allocating 19-20% of GPU memory, or in the case of 3GB cards, ~600 MB of VRAM. The current dag size is 2.39 GB, which is why on Windows 10 the Dag file is having trouble being allocated to memory on a 3GB card. The -eres switch and other workarounds are only temporary patches until the Dag gets bigger with every new epoch. Ultimately the longer term solution for 3GB cards is to move to an OS that allocates less VRAM, like Windows 7 that only allocates ~5% or Linux.
