Hello, I have two 4gb platforms both working with RaveOS
One of them is an old platform with an ASUS P5K DELUXE motherboard that works perfect for me with the latest version 1.18 --4g-alloc-size 4080 --zombie-tune 1 with four rx584 generating on average 21.5 MHS each card
My other platform an ASUS B-250 MINING EXPERT with 13 RX584/574 using the same parameter --4g-alloc-size 4080 --zombie-tune 1 I always get 4MHS always on five cards

and on the other nine cards I get 21.5 MHS
I've already tried everything, the motherboard has pci GEN 2 activated, I've changed --4g-alloc-size 4080 to 4078 4076 4074 so on until I reach 4060 and it doesn't increase the speed on those five cards, change the risers and nothing changes.
Is it a problem with ASUS B-250 MINING EXPERT? I can't use --zombie-tune 0 because the platform crashes instantly at startup, this doesn't happen with version 1.17 which works great on this platform using --4g-alloc-size 4080 but with 20 MHS on average on each card
I also want to thank the creator of lolminer for his great work is without a doubt the miner with the best zombie mode of all
For the rig is not working properly... you can use --
zombie-tune individually for each card. Try first 0, later 1 and later 2. Analyse which are the best values for each card and put them in order separate by , for example 2,1,1,0,1... so that will give you the best performance.
I.hope that improve some extra!!
