Hello o7

I am trying to mine some ETC Classic but something it is bad with DAG generator aka:

GPU1: NVIDIA GeForce GTX 1060 3GB (pcie 1), CUDA cap. 6.1, 3 GB VRAM, 9 CUs
GPU1: Allocating DAG (2.66) GB; good for epoch up to #213
CUDA error in CudaProgram.cu:388 : out of memory (2)
GPU1: CUDA memory: 3.00 GB total, 2.43 GB free
GPU1 initMiner error: out of memory
Fatal error detected. Restarting.

Ok acording to GPU-Z gpu what i want to use for mining it have in use 151 MB ok, now let's do some simple math 3000 MB - 151 MB = 2849 MB free, soo IF DAG it require 2.66 then i will do agen math 2849 - 2660 = 189 MB Free!!! so my question is how program it not have inaff free GPU memory ?! i am scraching my head trying to not get in infinite loop error

p.s. gpu what i try to use is secondary for windows /own need i have other one ... same i was test nanominer it working, gminer and lolminer same issue fail on DAG allocation with is strange ...

cheers
