Hello fellow ETH miners! I've been having some issues lately and wondered if any of you might have experienced the same thing and figured out a workaround...

On 3 of my 4 Windows 10 6x470 rigs, GPU-0 is causing issues. Many times it runs at a slower speed (20-21 vs 25-26) and also ends up eventually causing a "GPU 0 hangs in open CL - miner restart" error. Sometimes this ends up occurring every couple of minutes, which obviously kills mining rewards.

This problem seemed to start popping up after the Windows Fall Creators Update was installed on these rigs.

I had a similar speed issues with Claymore Cryptonite miner... always GPU0 again on all 4 rigs... and this was fixed be manually designating the "-h" value for GPU 0 at slightly below default and leaving the other 5 cards at the 0 defalut.

However, I see no such "-h" value option in this dual ETH miner, so wondering if there is another setting that I need to manually adjust to help fix this issue with my GPU 0's.

Any suggestions would be warmly welcomed!

Same here but with reds (4x Nitro+ 570 & 2x Nitro+ 580) + Win10 x64. After 1-2-4 hours new "Claymore Dual Miner 11" shows me "GPU hangs in open CL...". And it can be GPU 3 or GPU 4 or GPU 5, just randomly. Tried it all with different settings, set no memory errors at HWinfo, changed PSU, changed all risers, tried ETH-only mining - the result is the same, hangs - miner restart windows by "-r" command and again.

Mr.Claymore I deeply respect you for all the work you've done here but please clear the situation. I also see that a lot of people are facing the same issues. Thanks.
