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?

[ep690d]

clock 1366 mem 1750 undervolt -120

[ep690d]

After 2h5m no rejected  impressive!

clock 1366 mem 1750 undervolt -120

What power consumption?

[ep690d]

138w HWiNFO64

[dhan000]

undervolt -120

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

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.

I use Sapphire TRIXX
but in HWiNFO64 i see GPU Core Voltage 1.000V

But on my 580 cards memory not 300MHz but on full speed. How I can make downclock of memory?

AMD RX580 Pulse 4GB - 54,7MHs on lyra2v3
Nvidia GTX 1070 8GB  - 45,8MHs https://nlpool.nl/bench?algo=lyra2v3&chip=6

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

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)?

No, to this card not connected anything... With fullspeed memory hashrate is 53MH, with 300MHz memory - 52,2MH. 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.
