Mining ok until 2nd NVIDIA 980ti added - then get below error

hi all, first post, so apologies if I've missed something obvious!

I'm just starting to play about with Claymore, any its all worked fine (On my single 1080ti) until I added my old 980ti. It starts ok, but half way through the initialisation; the following comes up:

19:48:54:136 1540 ETH: checking pool connection...
19:48:54:140 1540 send: {"worker": "", "jsonrpc": "2.0", "params": [], "id": 3, "method": "eth_getWork"}
19:48:58:528 3614 GPU 1, GpuMiner cu_k1 failed 4, unspecified launch failure
19:48:58:533 3614 GPU 1, GpuMiner kx failed 1
19:48:58:538 3614 Set global fail flag, failed GPU1
19:48:58:542 3614 GPU 1 failed
19:48:58:546 1b84 GPU 1, GpuMiner cu_k1 failed 4, unspecified launch failure
19:48:58:550 1b84 GPU 1, GpuMiner kx failed 1
19:48:58:554 185c GPU 0, GpuMiner cu_k1 failed 4, unspecified launch failure
19:48:58:558 185c GPU 0, GpuMiner kx failed 1

I'm on Windows 10, 64-bit, and have assigned plenty of V-RAM as specified in the read-me
I'm on latest NVIDIA driver (I tried going back to the specific driver specified but hit troubles - I can press on harder if you all think this is the cause?)
I'm on a 1KW PSU, using separate cables.
I tried a different slot for the 980ti
If I disconnect the 980ti, it works fine again
Win 10 all up to date
I've tried a few command line parameters, no joy

Anything obvious?

Thanks in advance...!!

    Could be a driver issue

    Could be a overclocking issue

    install CUDA 8.0 (you need visual studio 15 to do this too) there's also a patch for CUDA 8 so make sure you get this too

    Let me know how you get on!
