So I been at it for 3 days now. I have a tb250 mobo and 5 gtx 1060 3gb cards I am working with. After setting them up and using msi afterburner using settings 65% power limit, 200 core speed, 750-800 memory and fan setting at auto and fixed at 75%. I cannot get more than 15 minutes of mining as afterburner becomes very unstable(laggy) as soon as profile is set. Letting it continue to mine in its laggy state it eventually drops a gpu temperature and fan reading to 0% and then slowly effects all other cards and it finally comes do a code 999 error on claymore stating cannot get current temperature (a internal driver error occured) .. So I used ddu and reloaded the latest drivers and reinstalled msi afterburner and are back at the same place with the same errors. I need guidance here. As I can not narrow down the issue. I have a suspicion that it might be afterburner causing it. Where do I start to diagnose.

Its like that when you clock memory to high, drop it by -100mhz and your be fine, claymore start reporting problem as soon as part of NV driver fail for unstable GPU

Thanks for the reply. I tried those clock speeds from 100-200 and still the same problem. Worth another try. I'm running out of ideas so pretty much I will try everything again until I find the issue.

what cpu?   

if it is a celery stick or a pentium


put   


-ethi 4 in your bat

then if it works

-ethi 5


if it does not work  -ethi 3

We are on to something here. Yes it is a Pentium g4400 cpu.

Its has nothing with a CPU, I already sad what it is... I have same problem with memory on +900-1000 (samsung gainward 1070)

Lower the memory by -50 and dual mining getting around 21.6 mhs from them. Also system is a lot more responsive and stable. Thank you will update on overnight results.

Ok so it didn't last long at all last night. Noticed that gpu 4 fan speed went to 0% a half hour into it and then also dropped gpu 0 shortly after. Causing claymore to crash! Could it very well be my power supply causing the issue? What else can cause this?

Put card at default.... then you will see

My MSI don`t go over +800 and micron just +500 (MSI)
