I'm having a problem with a crash or lockup when starting.  I've tried 11.3, 11.4 and 11.5.  All exhibit the same issue.

Claymore runs great when I don't set any GPU parameters in the config file.  However, as soon as I add any clock or voltage adjustments to the GPUs, one of 3 things happens when I start the software:
1. BSOD with Thread Stuck in Device Driver error
2. System just locks up (no mouse movement or num lock), requiring a hard power cycle
3. It starts properly but eventually exhibits failure 1 or 2 after an hour or two.

When I say the problem happens with any GPU parameters, I've tested this by using all stock settings (the same that the GPUs default to when I don't set anything in the config), but I still have the problem.  So, the problem is not settings outside of a stable operating range.

The crashes usually occur after "POOL/SOLO Version", but not all the time.

I checked the logs but nothing stands out.  The logs look normal then just stop when the crash happens. 

I'm running a rig with 3xRX570 and 3xRX580 using the blockchain driver on Win10.

I've tried running -oldkernels 1, but that actually made it worse.  I couldn't start mining at all.  I always get OpenCL errors, even with no clock or voltage adjustments.

I tried -gser1 and -gser 2, but neither of those helped.

Is there something else I should be looking at?
