RX580 4GB Pulse (Elpida) stock bios strap 1500+ and undervolt -120
54.4 MHs lyra2rev3
Slight performance improvement on 0.3.10 release 54.4 to 54.7 What core clock and voltage you're use?

undervolt -120
how is this done. This is how the undervolt is made.

After 2h5m no rejected impressive! Thank you! After filtering for a few random rejected shares due to new jobs there shouldn't really be any rejects though, so we're just where things should be . Also, the kernels are designed to handle a downclock of mem all the way down to 300 MHz on Polaris cards and 500 MHz on Vegas, this without hashrate being affected. It probably won't save more than 1-2W per gpu, but always something.

Use OverdriveNTool

Speed with memory on 300MHz is slower than on full speed... About 1 MH on my RX 580 8Gb

Would you guys be able to dev mimblewimble miner? Seriously lacking a good AMD one to compete

Speed with memory on 300MHz is slower than on full speed... About 1 MH on my RX 580 8Gb YMMV, the 580 in my test rig handles it fine. It's such a tiny power save anyway, just find the spot where you don't lose perf, I've seen people putting it around 1000-1100 MHz, for example. Out of curiosity though, is this your 580 driving monitor(s)?

Core clock and voltage the same...

Trying out the latest version and the duplicate error have disappeared for me and rejected rate down to almost 0%. Very nice! Hash rate seems to gone up a bit for most my cards.
The only thing i'm trying to fix is that on two of my miners, i have one dead gpu. Not sure if that means i have to mess around with my overclock settings. They all start off ok but anywhere between 1-10 minutes a card just dies and i don't know why.
And I agree with the sentiment that adding some other algorithms like mimble wimble would be pretty nice. The options for amd for new algorithms is sadly lacking.

It sounds like a classic clock tweak situation, they just need some TLC. Lower core clk and/or higher core voltage, try it in small increments.

That's what i was thinking too but never have messed much with it. Ok so on GPU P0-P7 and Memory P0-P3 i have them all set to 900mv. Which value would be the core?

I'd start bumping it +5mV at the time, and only for the problematic GPUs. Are you using OverdriveNTool? If so, it's good to run the miner with --bus_reorder so you get a GPU order that matches the PCIe bus id order, which is what ONT is using iirc. You can also run the miner with --debug and you'll see the current values for clocks and voltages read from ADL. This would be to verify that you have increased the voltage for the correct GPU. Note: I assumed you're running on Windows here, but I believe it would work under linux as well, although you'd have to use other tools to set clocks/voltages of course.
