AMD Rebrand - RX570 / RX580 - Official Thread

[greatauror28]

It’s amazing how entitled people are when they join this board, thinking everyone will willingly give them what their need.

 

I see what you mean...I tried to be nice and asked any tip for a first bios for rx560s, and let people free download it.
Guess what, 800 downloads later, not a 0.00001ETH on my wallet
Not only that, some people took straps, put rig into fridge, ran 16.x MH/s and scammed some people for 0.3ETH
(hi Minerscott)

That's why I don't blame you or others to be secretive of their discoveries aka bios mods as we spent precious time and effort doing it up to the wee hours of the morning. it's not remotely fair to just give it away.

I do try to help in my own little way and extend a hand, but people mostly want the whole arm.

Guys, I am struggling for two days now, maybe someone could help.

I have 6 x Sapphire RX 580 Nitro+ 8 GB and I am not able to use 6 of them. My bios is modded properly and they work fine if I use up to 4 cards in a rig. But once I get more than 4 cards - I have cards visibility problem.

I have tried numerous drivers options, blockchain drivers work the best, but they only get 4 cards max to work (for some reason, they work if the patch is no applied).

I have also tried configuring motherboard bios, disabled secure boot and switched PCI-E to Gen2.

Is there any possibility that my motherboard (Asus H170) is not able to take on more than 4 cards? One of the power connectors is not plugged in (Molex/M2).

Has someone else experienced this? Does this look like a purely driver issue?

I would try checking all your connections and make sure your power supply is large enough for all those cards.

Also I've seen that after mods the drivers may need to be reinstalled.

I found that on the Asus H270 you need to enable "Above 4G Decoding" in the BIOS to get it to see more than 4 cards.
Video here of how it's done: https://www.youtube.com/watch?v=Z1FnEYI25z0

Found this post, on another forum, on how to do it for the Asus H170: https://forum.z.cash/t/issues-with-mobo-asus-h170-pro-gaming-cant-detect-6-gpus/8754/9

"'i've just signed up to let people know I've been successful in getting 6 GPUs to work with the Asus H170 Pro Gaming motherboard, here's how I got it to work (after much reading and trying different things):
    Update to the latest BIOS
    Enable new setting in BIOS "Above 4G Encoding"
    Installing Windows via UEFI, not the standard MBR version (easily done with a little application called Rufus to create a UEFI bootable USB)"

I have a Dataland RX570 4G X-Serial   hynix , only 22.9M. how to improve? 

[WhyMe]

Do all rx580 come with a 6 pin power connector, or do some require 6+2 power to run correctly?

Actually, some need both 6 and 8 pin connectors (or, as you call them, 6+2)

I have the same cards and they happily mine with only the 8-pin connector plugged.

Yes they do...I was just answering the question

But they don’t *need* both 8 and 6 pin to run.

I guess a better statement would be “yes, most cards has an 8-pin connector but some comes with 8+6-pin. However, they don’t need both connectors to mine IF you undervolt.”

There! 😊

One of my 570 Nitro+ NEEDS 8+6, without 6 it's not stable.
With no big OC or big voltage.

What clocks do you run them at? Also what voltage?

It's just interesting that a higher, more powerful GPU that has a 225w max tdp don't need the 6-pin to run while it's younger brother that's supposed to run slower and cooler needs it.

It makes zero sense.

Try lowering both of your voltages to 900 or 875, as your 1125 clocks don't need much voltage anyway.

I believe if your cards don't consume >150w at the wall, it won't be needing that 6-pin plugged.

[RealSwissMiner]

I agree with what was posted above the additional 6PIN connector is not necessary if you keep the GPU clock below 1250 Mhz. I also have the Nitro 570+ and works like a charm.

Hey there fellas, may I get some stable and undervolt BIOS for XFX RX 580 GTS Black Edition with Samsung memory and Sapphire RX 580 Nitro + with Hynix memory?
Thanks in advance.

Here are a few suggestions you can try, I've used them all and they work fine. Remember, every card is slightly different so what works well for me may work even better for you

You could also use Polaris Bios Editor and select the "One Click Timing Patch" option.

Hello guys, i'm new here, i recently started mining with my pc, i'm using a gigabyte rx 580 gaming 8g with samsung memory and modded the bios by copying 1750 strap to 2000. I'm currently using NiceHash for mining but i feel like my hashrate is lower than it should be, CryptoNight(sgminer) on nicehash gives me around 585 H/s on average, DaggerHashimoto does like 23 MH/s max and it dips down to 18 MH/s most of the time, Equihash does around 271 H/s.

Running the card with these settings: core:1200 memory:2100 vcore:-93.

Would you recommend to change some of my settings? Is there any other bios mod that would help me further?

Something is wrong there...strap copy is not perfect, but numbers you get are way too low

That's too low. After seeing 23 MH/s only I'd assume the wrong drivers (not blockchain or the latest ones with the compute switch), but then the cryptonight hashrate should be higher with any drivers. Try more aggressive timings like these:
777000000000000022CC1C00AD615C41C0590E152ECC8608006007000B031420FA8900A00300000 010122F3F88354019
or
777000000000000022CC1C00AD615C41C0590E152ECCA60B006007000B031420FA8900A00300000 010122F3FBA354019

These are pretty tight, so don't flash high memclocks at first.

Also what temps are you getting? -93mv might still result in too high voltage for rx 580, so your card might be throttling (that would explain the dips in hashrate).

About the drivers i'm using the latest ones (not the blockhain ones), haven't tried blockchain drivers since i'm using this gpu/pc for occasional gaming too and i thought blockchain drivers would affect gaming perfomance (not sure about this).

Just to be sure i should copy those timings on the 2000 strap right?

About the temps i'm getting max 77C with fan speed going between 33 and 50% only, power consumption on msi afterburner is 107w max.

Edit: forgot to mention that i'm not changing voltage or clocks on the bios, i use msi afterburner for this.

[wacko]

About the drivers i'm using the latest ones (not the blockhain ones), haven't tried blockchain drivers since i'm using this gpu/pc for occasional gaming too and i thought blockchain drivers would affect gaming perfomance (not sure about this).

Latest amd drivers now have a switch that allows you to select between workloads, so I guess there's no need to install the blockchain drivers anymore.

Just to be sure i should copy those timings on the 2000 strap right?

Yes, if you're mining at memclock above 2 GHz then all you need is to just change that single strap.

About the temps i'm getting max 77C with fan speed going between 33 and 50% only, power consumption on msi afterburner is 107w max.

That's too high. Use proper software for clocks/voltages, OverdriveNtool is good. MSI AB is no good for AMD cards, it doesn't have enough controls to properly tune Polaris cards. Most cards are stable @ ~ 0.9-0.925V at 1200 MHz, and you're running yours at higher voltage than you have to. Hence it's too hot and you're wasting electricity as well.

Okay i tried a few things, i did a clean install of the latest driver (17.11.2, i had 17.11.1). I modded the bios with the 1st timing that you suggested me, i closed MSI AB and got OverdriveNTool, got these settings for now: core:1200, memory:2000, vcore:950, target temp 73C, max temp 90C, acoustic limit 900 MHz.

I ran a first attempt with NiceHash on DaggerHashimoto for 15 minutes with the driver toggle on "Graphics" and i got around 26.6 MH/s but after a while it dipped down to 20 MH/s, max temp 73C and fan speed 40%.

Second attempt (currently running for 25 mins) driver toggle on "Compute", started at 27.2 MH/s, currently running at ~26.5 MH/s, 72C fan speed 39%.

I guess these hashrates are looking more normal now.

The most likely reason for those dips you're getting is overheating. Set target temp to 60C. And try to increase memclock over 2000 MHz. After that try lowering voltage in small steps. Keep in mind that your "memory voltage" should be less than or equal to your core voltage. So if you set 950mv in the left column for the core, you also need to set it to 950mv in the right column, where you memory clock is.

I tried overclocking the memory up to 2150 MHz while also adjusting the target temp but the hashrate was the same so i went back to 2000 MHz, now i set the voltage for the core and the memory on 900mv, getting steady 26.6 MH/s so it's ok, way better than before. I left the target temp on 67C because the cooling on this specific model is not very good and if i set the temp lower then the fan will get pretty loud.

Thanks for all your help!

It shouldn't be the same. Do you restart the miner when you apply higher clocks? If you keep the miner running while increasing the memory clock, you might not see any improvement in the hash rate. Gotta restart the miner.

At the moment you're better off mining ETN than ETH. Not only you'd earn ~ 25% more, but your card will also be cooler and quieter (since it's cryptonight algo so it's not as power hungry as Dagger).

Rx 570 8gb Sapphire Nitro+ Dual mining ETH+DCR 29.8 mh/s  + 600 mh/s with 130W @ wall.. I guess there is still some room for improvement about the Wattage right?

Not much, if any. What clocks and voltages are you at? Not hard to figure out whether there's any room anyway, just keep decreasing the voltage. If you decrease the core clock, you'll start losing on DCR hashrate, so to keep the same hashrate the voltage is the only thing you can adjust. 130W for dual is pretty much normal consumption, not many cards can go below that.

[Cereberus]

Cryptonight algorithm even without modified BIOS requires 95-100 watt power consumption , I personally measured it at wall with a Lafayatte power meter. If you can modify the BIOS the power consumption will be even lower.

Now a natural question come to my mind, why the price of these cards doesn't decrease ? RX Vega is equal to 3x these cards in Cryptonight algorithm and about 500-600 USD one. The price should decrease and decrease a lot, no one would buy these anymore with the actual prices.
