5 GPU's at 1000w? Probably need more power.
Check your RAM? 4gb min and add virtual ram to include 16gb or your hard rive too.

1000W is plenty for 5 GPUs Eth only. with undervolt, 6 GPUs takes ~730W at the wall, so perhaps ~670W of PSU output. You could feasibly run 7 if there were enough connectors.

Dual mining different story, 1200-1300W PSU would be recommended.

thanks, but i have 1800w look at my post. RYXES does not see that i have 1000w + 800w

my problem is 'hangs on opencl call' and now i dont know where i have to search Wink

If it is saying that for a certain GPU, you need to turn down your overclocking.

I have noticed that a one of GPU might hang up and has 0 MH if:
- Has too overclocking bios: for example, RX580 8gb MSI with BIOS 31 mg/h with 6 GPU works unstable and gives the same average hash rate as with bios for 28 mg/h which works stable.
- unstable power. I mean deliver a quality of power. When I had bougt and install additional voltage regulator for all office rig starts work more stable.
- also, some of overclocking AMD GPU could prevent boot a PC.
