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
Ya I saw you have 1800w, I was just correcting RYXES.
If a rig is unstable like you say, it may be risers or motherboard. Look at logs see if it is one GPU in particular and try changing riser. Can also unhook all but one, and incrementally test. In Windows can use HwInfo64 to check for mem errors and other things. I had a Biostar TB250 mobo would throw lots of PCIE errors, resulting in about 20 reboots per day. Replaced mobo, rock solid. I don't know if there is a Linux tool. My experience with Linux has been figuring out the desktop is a PITA, and VMs/Server for webdev work.
