OpenCL failed

[BrianTheDreamer]

Hi,
I have an Alienware Aurora with NVIDIA Titan Z Dual GPU.
I know I'm suppose to use cuda but somehow OpenCL switch gives me better results (~40 sols/s).
I was using this line in v0.3a
nheqminer.exe -l eu -u [myWalletAddress].OpenCL -t 8 -op 0 -od 0 1
and its working fine. But in the new version (0.4b), I just changed it to
nheqminer.exe -l equihash.eu.nicehash.com:3357 -u [myWalletAddress].OpenCL -t 8 -op 0 -od 0 1 and its either just exiting, or giving fail OCL error.

I also noticed the new switches in OpenCL section
-ov, 0 gives OpenCL error: -1001 at opencl.cpp:14 and -ov 1 gives fail OCL error
-ot, Do I have to specify value here, or can I skip this?

I tried copying the OpenCL.dll from v03.a but it makes no difference.
What could be causing OpenCL to fail?

Thanks in advance.

-1001 means that platform does not exist. Show the output for -oi, please.

AMD (OpenCL) solver are dropped from nheqminer.
Closing issue...
