Cmd crashes if I try to use my GPU to mine on one rig but not another

I have 2 rigs with different GPUs, apart from that they’re almost identical.

The rig with a 660ti will just crash and close unless I stop trying to use the GPU

The rig with a titan x though works fine. any reason why or work around?

I’ve tried the nheq miner and the flypool modified nicehash one.

any help would be great :smiley:

Edit: I get the message worker not authorized, any idea why?

Wrong bat file ?
Also try using -t 0 to disable the CPU or maybe not run it at 100% with the rig that crashes

Shouldnt be the wrong bat file, its the same as the other one but with a different worker name, works on a laptop and the first rig just not the second
