Thanks for lots of great straps to try, and undervolting advice. I have four RX580s, headless rtos rig, almost ready to go.
I'm going to try a v1.6.7 version(free) of Polaris BE, because from what I am reading here, it seems to be all about the custom straps. I like walking on the shoulders of giants, and since I've never even mined before, and I found a giant, or a master, I think I'll journey[-man] one (more) time. Object-oriented, Larry Wall perl idea be lazy not crazy, etc.
Here's my intro to "giant" or "master" or "guru", and his free PBE version

I think with this version of PBE, I detect the personal style and nuance of Jason Kurtz aka The Doctor aka tekcomm* usernames. He is an outstanding developer, having worked at Motorola, and programmed the Scientific Atlanta TV set top boxes, and was in the dev crew working with Linuxium on linux for cheap Chinese 2-in-1 touch screen small laptops with Bay Trail and Cherry Trail bios, when I first encounterred The Doctor and his work. Most notably for us, however, he developped the Rocm Rippa real-time-operating system(RTOS) by stripping down Ubuntu linux, and using rocm atomics. I call that Highway 361 Revisited Tour, because in same style as for his version of Polaris BE, he announced his goal, and then vanished--deleted his git username for "git rocm issue #361" i.e. "Highway 361". I know his gmail and you can find him easy by websearch. He likes solving people's problems for digital coin bounty, when you find him.
If you are interested in joining the Highway 361 Revisited Tour, in The Doctor's inimitable style, his v2 stripped down Ubuntu rtos rig, rocm rippa, check out the rocm Issue #361, closed but that makes no diff and Earl Co and gstoner might respond. I am currently sleuthing what the blacklisting and whitelisting and commands are that make The Doctor's v2 rocm rippa work as rtos, while upgrading to Ubuntu bionic beaver and upgrading amdgpupro to August 30 version compatible with beaver, and upgrading rocm and anything else. Until I get to a good stage, maybe able to install Ubuntu, run a script in two seconds, strip it and make it a blockrippa in fashion of The Doctor rocm rippa, you can try Earl Co's fork v2 v3 v5. I can also try to pull custom straps from The Doctor's PBE, and put them into a later than v1.6.7 version of PBE, and put that out separately and in blockrippa update(fork?) on v2 rocm rippa.
