Topic: Sapphire RX580 Nitro+ 4GB Hynix - Need help with rig (only 20MH/s in dual mode) (Read 2329 times)

RazerBoy, your problem is that you do not use the proper OS system. My rig under windows takes 870W from the wall. has 29.8 MH per card and has restarts approximately once per month. As an advice - never use such a bad tool as MSI afterburner!!!

Hey guys,

if anyone is using the FREE ethOS I linked ( this one: https://bitcointalksearch.org/topic/want-to-start-eth-mining-with-ethos-124-free-2164617 ). DO NOT USE IT. I had major network problems because of it. When I did "ping 8.8.8.8" I had delays up to 5000-7000ms. When I pinged my local router I also had horrible delays. In the end, after like 5-7 hours of figuring out what's wrong I looked at the processes in ethOS and found out a program was using most of my network. The thing looked like a teamviewer thingy, but it wasn't teamviewer. Looked like a remote control program of some sorts. I forgot the name of the program(I have a friend that I work with on the miners and he actually figured it out, so that's why I forgot the name (even thought I was next to him for the whole time xD, was trying out other stuff). But I'll ask him and update this post.). So yea... Don't use the ethOS that I've linked. I just had problems because of that. The program is probably a backdoor (but a really bad one, since it literally bricked my network somehow, because it was using up soo much of my connection. I couldn't mine... So what's the point, he can't steal that which does not exist ) into your computer (probably a russian / asian guy trying to get your satoshies). I could've literally mined for like 1-2 weeks constantly if that hadn't happened (I have very little time during the week and I'm also not physically next to the miners, so I can't really put as much time into them as I'd like). I recommend you buy 1 copy of ethOS. That's what I did. It's 39$ and you can use it on as many rigs as you'd like (even thought it says on ethosdistro.com "1 bought copy = 1 rig"). You need only 1. You don't even need 1. But I can't find a free version that I can trust, someone needs to upload 1 clean version and everyone can share it. Since it's a ubuntu distribution, which means you shouldn't be able to charge for it. But you still CAN, if you think people will pay you for it. You should just install the bought (or just a copy you trust) distro on 1 HDD/SSD/USB and then just clone the disk to your other disks. I just plug both SSDs into my main computer, which has windows and then I use a tool called EaseUS something something (google "easeus disk cloning"). And then I choose the "Clone" option and clone the disk.

So yea, to sum it up. DON'T USE THE FREE ETHOS LINK I POSTED, IT PROBABLY HAS A BACKDOOR AND IT FUCKS UP YOUR NETWORK (at least that's what it did to me, I couldn't mine with 2 miners at the same time and stupid stuff like that).

This should get you 30.35MH/s on ETH and 9.1GH/s on DCR with a bit less than 150W power consumption

did you upload it anywhere? Please help if you can because I really want it

Look at my ethmine account. Under Payouts / Rounds. But you should wait for a few days. The avg hash rate of 24 hours needs to stabilize first. Also I can't show you my DCR income, since I mine DCR on suprnova and I'd have to give you my account password in order for you to see . Also suprnova doesn't calculate per month income xD. But look in the upper post. I've posted a picture

The GPU gods have spoken!!!

I've increased my hash rate to 30MH/s on ETH and 900MH/s on DCR.

I took a look at this tutorial: https://bitcointalksearch.org/topic/guidetutorialxmrethhow-to-mod-bios-rx470570480580-vega-mining-1954245

My starting BIOS is Sapphire Nitro RX 580 Powersave 2100 OC Anorak's 256k.rom(https://anorak.tech/t/sapphire-rx580-nitro-4gb-hynix/4637/32) posted by jgspeer (TY you slick bastard ).

I downloaded SRBPolaris. I then proceeded to tame my beasts. I under volted to 950mV, then I upped the core/GPU clock to 1150MHz from 1075MHz, kept memory clock at 2000MHz, downed the TDP to 100, and I copied the Hynix straps from this guys tutorial. I copied them to 1500 and all above. Strap: 999000000000000022559D0010DE5B4480551312B74C450A00400600750414206A8900A00200312 010112D34A42A3816
If you really want the BIOS just tell me where I should upload it. I currently don't know where I'd put it . Write in the comments below. DON'T TRY TO PM ME FOR IT. JUST FIND A SITE I CAN UPLOAD IT TO xD!

They're at 30MH/s / 900MH/s. Picture of my tamed kittens purring away: http://prntscr.com/gxmj7g. The total power usage of both miners is 2200W. The system uses about 50W. 2200 - (2 * 50) = 2100 / 12 = 175W, which I think is very high.
QUESTION:Do you guys have any ideas how I could get to like 130W? Preferably lower... But even 150W would be good....

If you want to see my kittens purr you can go to https://ethermine.org/miners/C790b438b741735079AC50031DF253ADcCB09D45.

QUESTION:Look at my ethosdistro panel. You can see everything EXCEPT watts. How would I make it show watts? Do I need to do anything special for it to show me the watts? If you know please help !

If you believe I helped you out and have too many satoshies to spend, you know... here's the address :

on the current settings that you have what is your $/day?

Hello guys,

I've made some adjustments to my rig. I was reading through this section http://ethosdistro.com/kb/#many-gpus. Under "Common BIOS Options for fixing Kernel Panic with 5+ GPUs" -> MSI Motherboards. It said to set PEG1 to "GEN 2", set PEG2 to "GEN 2" and set PCI Latency to "96 Cycles". I also disabled HD AUDIO CONTROLLER.

The hash rate didn't increase from this but fine.

Then I've discovered a setting called "globalpowertune". If you look in the documentation of local.conf on ethOS 1.2.5 it says this: # globalpowertune: set the power tune setting of all GPUs (notes from dev: 20 is default/max on everything except 290/390; r9 290 should use 50). I had my powertune setting set to 5. I changed it to 6. The hash rate went up. Changed to 7. Went up. Changed to 14. Went down. Changed to 8, went down. Changed to 4, went down. changed to 2, went down. I then decided that 7 is the best value. I now have 28.5-28.6 MH/s on ETH and 860 MH/s. Before I had 28 MH/s on ETH and 843 MH/s on DCR. So a 0.5 MH/s and 20 MH/s increase for just doing that.

Pic of Claymore now: https://prnt.sc/gw8z7a

Oh and btw, the 4th question I asked in my last post (why so many incorrect shares on GPU0). It was random. It's not happening anymore... So I guess at least that fixed itself.

Also about the 2nd question. I found start.bat. It's in /opt/miners/claymore in ethOS 1.2.5. But claymore doesn't seem to run from this start.bat. I deleted the content of it and it didn't matter. So adding

GPU_FORCE_64BIT_PTR 1
GPU_MAX_HEAP_SIZE 100
GPU_USE_SYNC_OBJECTS 1
GPU_MAX_ALLOC_PERCENT 100
GPU_SINGLE_ALLOC_PERCENT 100

won't probably do anything... But I'll investigate further and see what I can do. Maybe I can somehow have it start from this start.bat, so I can control exactly what happens...

But I still want to get to 29.5-30.5 / 900. So please, share your knowledge.

Thank you for your answers as always !
Hope my information helped some of you guys!

Hello fellow miners,

As promised I'll share my data with you.

First off, I got my copy of ethOS 1.2.4 from here https://bitcointalksearch.org/topic/want-to-start-eth-mining-with-ethos-124-free-2164617 (DON'T USE THIS LINK TO GET THE FREE ethOS, READ ON 2ND PAGE FOR MORE INFO). I've then proceeded to follow this guide on how to install it http://ethosdistro.com/kb/#writing-windows and http://ethosdistro.com/kb/#using-kvm and http://ethosdistro.com/kb/#booting-ethos.

After I've done that and after I could see the ethOS desktop, I've updated the OS with this http://ethosdistro.com/kb/#updating.

After the update I installed claymore http://ethosdistro.com/kb/#adding-claymore. After that I've edited local.confing and claymore.stub.config so that it mines on my pool and some other stuff like fan speeds and so on.

After I've updated the OS I started testing out which BIOS is the best one. I've tried 5 different ones.


KEEP IN MIND ALL OF THE BELOW BIOSES WERE TESTED ON STOCK SETTINGS (MEM CLOCK, CORE CLOCK,  VOLTAGE). Also dcri is on 30.

Name of BIOS | Link to BIOS | Hashrate | Power consumption
1st BIOS: Anoraks_Sapphire RX 580 Nitro(plus) 4GB Hynix Elpida_memshift-1500.rom | https://anorak.tech/t/sapphire-rx-580-nitro/5017 | Too low to mention | Too high
2nd BIOS: Anoraks_Sapphire RX 580 Nitro(plus) 4GB Hynix Elpida_memshift-1750.rom | https://anorak.tech/t/sapphire-rx-580-nitro/5017 | Too low to mention | Too high
3rd BIOS: Sapphire RX580 Nitro Hynix 4G Mem1950 Gpu1195 27mhs 100w Ok LU.rom | https://anorak.tech/t/sapphire-rx580-nitro-4gb-hynix/4637/19 | 27.5 MH/s on ETH, 605-615 MH/s on DCR | 120-125W@wall
4th BIOS: Sapphire Nitro RX 580 Powersave Anorak's 256k.rom | https://anorak.tech/t/sapphire-rx580-nitro-4gb-hynix/4637/31 | 26.7 MH/s on ETH, 590 MH/s on DCR |105-110W@wall
5th BIOS: Sapphire Nitro RX 580 Powersave 2100 OC Anorak's 256k.rom | https://anorak.tech/t/sapphire-rx580-nitro-4gb-hynix/4637/31 | 28.2 MH/s on ETH, 610-630 on DCR | 120-123W@wall

As you can see the 5th BIOS is the best.


After I've found the right BIOS I've proceeded to put in the GPUs one by one and flash them one by one.
You flash bios like this on ethOS
sudo atiflash -i (you get the adaptor number like this)
sudo atiflash -f -p

After that I've also OCed the GPU with the local.config
Changed the mem clock to 2100MHz, tried to change the core clock but it just doesn't want to change for some reason. After I changed the core clock to 1100MHz and restarted the computer I checked the mem/core clock with "show stats". It changed the mem clock to 2100MHz, but the core clock dropped down to 1075MHz. After that I changed back the core clock to the default one and left the mem clock at 2100MHz. But even if I leave the core clock on the default value it's still 1075MHz (I really don't get why or how). Screen of the "show stats" command https://prnt.sc/gvmgjx. Screen of claymore mining https://prnt.sc/gvmfba.
I haven't yet tried under volting, but I will and I'll update this post when I do.

If I try to change mem clock to 2150 some GPUs don't even start in claymore, they just show 0MH/s. Also the hash rate on the ones that do turn on doesn't increase.

So now I still have questions for you guys.

1. How do I actually change the core clock, has anyone any experience with this? Anyone managed to change their core clock on ethOS? (USED SRBPolaris, GO TO THE SECOND PAGE TO READ MORE)

2. Where can I set up this settings in ethOS

GPU_FORCE_64BIT_PTR 1
GPU_MAX_HEAP_SIZE 100
GPU_USE_SYNC_OBJECTS 1
GPU_MAX_ALLOC_PERCENT 100
GPU_SINGLE_ALLOC_PERCENT 100 (FOUND WHERE THE START.BAT IS LOCATED./opt/miners/claymore. But ethOS doesn't use this to start claymore (doesn't matter what you write in here... but I'll investigate further))
and 16GB virtual memory. (THIS IS PROBABLY OK (BY OK I MEAN, ETHOS DOES THIS BY ITSELF/HANDLES IT))

3. How could I get more out of my GPUs? How would I get 29.5-30.5 MH/s on ETH and 900MH/s on DCR? Any more tips and tricks I could use? (SOLVED THIS, NOW I HAVE PROBLEMS WITH HIGH POWER CONSUMPTION, HELP ME GET IT DOWN PLEASE GO TO SECOND PAGE TO READ MORE)

4. Why does my GPU0 have so many "Incorrect ETH shares". Picture: After 11:55 hours of mining https://prnt.sc/gvqo1l, after 16:52 hours of mining https://prnt.sc/gvqnjg. (SOLVED BY MYSELF IN THE LOWER POST xD)

Hello fellow miner,

I have found a solution! I will share the solution in detail with you (after I finish setting myself up, probably tommorow), but for now all I'm going to say is this. I love ethOS. I'll share the full report of my venture tommorow !

Whats wrong with WIFI/Wireless LAN for mining?

Are you still on dcri 69?  Change to default 30 and go for lower numbers, AMD Cards don't like high dcri settings.  Best setting for me is 15 or 22 in dual mode.

If you get black screen connect your display to your iGPU or disable igpu in bios.   If you disable iGPU in bios connect display to your gpu that is in16x slot, even if it is connected with a riser. You need either a display or a dummy plug for amd cards if you're using windows. Than you'll able to oc your amd gpus.

Hey Branko,

Yes I did, both. And please read the first post. Everything is explained in detail in my first post. Even says this ! Also everything in my 1st post is mostly in order of how I did it

BIOS Above 4G Decoding set to Enable?

Also some say it helps to put PCI-E to Gen1

Hey Branko,

Yes I did, even tried the motherboard...

Did you try to plug monitor into all cards, maybe windows send output through some other card?

Hey hagbase,

I know not to mine on Wi-Fi. No worries. This is just a temporary thing since I'm not at home and I took my miner with me. I got no cable connection, so this will have to do for now. I'll move my miner back when I solve the hash rate problem and put it on a stable connection.

I've set -tt 68 as you said. They're at 67-68 now at 50-80% fan speed.

Yes I did switch dual BIOS towards the display ports.

Ok so about the black screen it's like this. I download/installed DDU. I then restarted the computer, went into safe mode. I deleted the display drivers with DDU. It then tells me to restart the computer. It restarts. Then I see the motherboard logo, then I see the windows dots spinning in a circle, then after that (this is when the log on screen should be displayed) I only get a black screen. I can't get into windows anymore. I have to reinstall windows or reclone the disk. I've another disk ready with the same setup (I've needed it a lot). So you see my problem. I can try uninstalling the blockhain display drivers from AMD again, but I'll probably get the same result.

By anoraks power save BIOS you mean? Please provide a link. Or do you mean the one I'm talking about in my initial post? This one https://anorak.tech/t/sapphire-rx580-nitro-4gb-hynix/4637 ?

However, 8GB cards use 8GHz memory, while 4GB cards use slower 7GHz memory

Did you move/switch  dual bios switch towards display ports? If so everything is ok.

Black Screen? Even if you don't patch driver with pixel clock patcher  you'll see  gpus as microsoft standard display adapter in device manager. Install driver in device manager  and than start pixel clock patcher and your gpu driver is signed and patched,reboot.
You need to unintall previous driver with DDU in win safe mode if you going to use blockchain drivers.

Yes there was a Trixx 6.5 download don't know why they removed it. Just use Afterburner beta 16+ or overdriveNtool : https://forums.guru3d.com/threads/overdriventool-tool-for-amd-gpus.416116/

With anoraks powersave bios try 1100 gpuclock / 2000 memclock even with one click timing patch try first 2000 Mhz for memclock.

Use https://www.hwinfo.com/download.php  to monitor your gpus (mem error, power draw).

Your gpus are way too hot, set -tt68 in claymore.   And don't use fucking wifi/wireless lan for mining.

i find the big advantage of 4gb over 8gb
is that the 4gb card runs at lower temperature then 8gb
