Testing version 1.19 on RaveOS
On my ASUS B-250 MINING EXPERT platform I no longer have the problems I had with version 1.18 using --4g-alloc-size 4080 and leaving in automatic --zombie-tune
testing if it's stable but at the moment all very well thanks for the update

kinda curious cuz i has the same problems with 1.18 and ive been looking at switching to more dense rigs
can u by chance console or ssh into ur mining OS and do a "lspci -t"?
so i can see how the pcie lanes are divided
it will be long but something like this
-[0000:00]-+-00.0
+-01.0-[01-03]----00.0-[02-03]----00.0-[03]--+-00.0

this is what 4 cards look like on a splitter, the last numbers are cards 00.0 vga 00.1 audio
and im assuming ur mobo has lots of them
placing only --4g-alloc-size 4080 or 4078 without placing anything else you still have problems?
