Hi there, i have a rig with 5 rx 470 4gb and 6 rx 480 with 8gb (gigabyte g1).
I have a problem every 1 hour running the rx 470 4GB rig or sometimes even less.
in the first run it shows at generating DAG file that have 4096 MB of memory in GPU for write and use.
after 2 hours of running, for some reason claymore reboots this is normal that random crashes, but when it try to mine again shows only 1920 or less MB of memory available for DAG, and because that the common cannot write DAG file problem.
there is a way or a command or something that is missing to free those 4GB of ram available for dag file between every reboot?
i saw that some people add virtual memory, i added 8GB of physical memory to the rig, also created a swap partition, and nothing... also i am using the z270 chipset i tried the simplemining 8gb and 16gb version and same... tried with 6 gpus, 5 gpus, undervolts, but at some point when it restart at some time it looks like it were eating gpu available memory and not releasing them....
i tried to search about this stuff on internet but dag errors are only on 2gb ram or less vga's issue not rx 470 issue...
the rx 480 nitro+ 8gb had no issues...
because this i am thinking to switch to windows, and see if this fixes or at least i know that can be fixed with virtual memory..
#1 the reason for restarts is you are pushing your GPUs too far.
I have 1 RX 580 that when OC it to 1950/1150 mem clock/core clock it would crash after 25 min restarting the rig. I underclocked it to 1750/1150 and rig is stable.
#2 I see you are doing dual mining trying single mining like ethereum only as oppose to ether + Sia and see if that fixes the issue.
#3 have you tried the following Image?

for me the second one works stable. on Z270 I have Asus Prime - AR Z270 Motherboard and i am using simpleminer-RX-v1093-4.11.rc8-16.60-enablerc60.imgc image.
