Hi all. My configuration is:
- ASROCK H81 Pro BTC / Celeron G1840 / 4gb RAM / SSD 64GB
- Raiser (here)
- 4x Gigabyte RX 480 8gb Gaming
- PSU Thermaltake 750W modular

I use Claymore 15.12 in Win7 x64 and I mined Zcash for 2 days without problem, with 1 or 2 RX 480. Driver ati vers. 17.
I need to use Win 10 because now I have 6 video card (all RX 480) but I always have crash just I start Claymore in Win 10.
At first I had an error about "stuck_driver" but after some attemps system crash without errors, only a grey screen.
In last 3 days I tried a lot of solutions but no 1 succesfully.

ATTEMPS:
1- Win10 (Home or Pro x64) with only 1 card. Crash
2- Win10 (Home or Pro x64) with more virtual memory. Crash
3- Different version of Claymore. Crash
4- Different variables of Claymore. Crash
5- Win10 full update installed. Crash
6- Different version of ATI. Crash
Always after 4-5min of Claymore running screen become grey and freeze. Reboot required.
A particular thing is that after reboot often appear a notific about WATTMAN of ATI that restart with default setting and I never changed it.

All same attemps tried on Win8.1 but same result.

I'm very frustrated. Can anyone help me? What can I try?
Someone talks about uppervoltage or undervoltage, someone changing BIOS, other about versions of Claymore or ATI driver...
I hope in your suggest to fix this.

Thanks

if you are talking about wattman maybe you are undervolting..
and if yes, maybe you are goin "too low"!
Try to rise some mV the GPU voltage CORE/MEM
