Hello guys

I build 2 Rigs
1)
Asus b250 mining expert
8 x sapphire rx 580 8gb nitro+
Corsair tx750w x 2
120gb ssd
Windows 10 64
16gb ram
I3 7100

2)
Asus z270-p  
6 xfx gts xxx rx 580 8gb oc
Raidmax cobra 1200w gold +
120gb ssd
Windows 10 64
4gb ram
Dual core processor

Both cards are giving only 18mh/s and temperature is between 72 to 77 for all cards hashrate out of the box & i don't know y. And the 1st rig displays every few minutes errors in miner & keeps on disconnecting from internet, plus it stops mining if you stop using keyboard or mouse

i will give $10 whoever solve this problem for me, it's very irritating please guide me.

Which 2 cards on which rig?

Which miner are you using, and what driver versions for your GPUs?

Did you use any BIOS modifications? Have you changed clock settings at all, and if so, using what software?

On your first rig, have you checked the driver for your NIC?

In order to achieve higher hashrate, you must mod your RX580

Drivers and Clocks also contribute to achieve those hashrates

Goodluck

i m using claymore Dual miner & latest drivers, i didn't even touched gpu, but i did some settings in bios to get all cards detect

is there any video tutorials?

Latest drivers? Is that blockchain drivers or normal gaming drivers?
These drivers are blockchain one:

I have a friend with exactly the same parts as your on rig 2(cards, mobo and psu). He modded his bios and have 30 Mh/s eth and 900 decred in dual mining.
I can ask him for the bios if you want.

Here are some videos I gathered around

More important is that, SAVE your bios before doing all the Stuffs

it might save your @ss later when all got F*cks up  ;D

It is hard to say what is wrong not seen this.Temp. gpu is normal otherwise replace term. paste on gpu.

When i modded my cards i followed this tutorial:

http://1stminingrig.com/best-bios-rom-sapphire-nitro-rx-580-8gb-oc-hynix-memory-30-mhs/

For your cards will be pretty much the same way, you just need modded bios for your type of memory.

The KEY point to get a good hashrate on Radeon cards, is to mod your memory timings in your BIOS

You need to follow the tutorial above : let us know :)

yes please
 & do i need to uninstall amd drivers? And then install this one? 

13 x ASUS RX 580 Strix O8G Samsung - 30.20-30.80 ETH (BIOS - custom) temperature 50C-60C
ASRock H110 Pro BTC+
ethOS 1.2.7 - Best OS
120gb ssd M2
Corsair 1500 + 2 x Corsair 850
32Ram
CPU Celeron

If you haven't figured this out, here's what you'd need to do. Launch AMD Settings, click on Global Settings, under GPU Workload, change from Graphics to Compute. You must do this on each of the card. This will pump your hash rate from 18 Mh/s to 24 Mh/s.

Those XXX cards have a switch on them near the power input; it's a "backup" bios, which is great (as I learned when I bricked one card while trying to flash it), but they also weirdly seem to be like a turbo setting, as all of my cards went from 24 to 29 with those switches flipped (I use Ethos so I was able to adjust memory and voltage a bit without flashing).

Also you need to adjust your claymore settings; try not dual mining and JUST mining Ethereum and see how you do. If it's significantly higher, your secondary coin is using too much of the gpu. When on dual mining I tend to lose around 20-30% of my ETH, but at current SIA value it is often worth it (I don't really mess with the Claymore settings, but there are plenty of tutorials for that both on the forum and easily googlable). Good luck!

That’s great. Glad to hear you got it working.

I’ve recently set up a rig with these cards. Luckily I get them all to run ~29 Mh/s. Time to sit back and enjoy it 😄

You've bought 12 RX cards and don't even know how to set them up properly??? Ignorance is bless...

Hi,

I'm working on getting my first Ethereum rig up and running and I'm getting pretty low hashrates and hoping that somebody could help me out.

Currently, I have (2) RX 580 8GB MSI Gaming X cards and I'm getting 23.xxMh/s out of each. Obviously, I'd like to be getting closer to 30Mh/s.

Out of the box, they only got about 18 or 19Mh/s, but after modding the BIOS, they're up to the 23Mh/s, but I've spent a lot of time searching and trying different things to try to improve the performance and I'm just stuck.

I downloaded the Polaris editor, clicked the "One Click Timing Patch" button and re-wrote the BIOS the cards. That's what took me from 18 or 19 to 23.

What am I missing for getting them to 29 or 30+?? I am new to modding BIOS and overclocking GPU, so if you wouldn't mind some specific instructions on how to do some of these things, I'd appreciate it. I keep reading about certain settings, but nothing really goes through the steps that you have to follow to make those changes.

Thank you very much and I appreciate any help you can offer!

This is a good site on how to setup and optimize your rig.

lower core to 1160, up memory to ~2000, and use blockchain drivers.  Should get you ~28.  More aggressive memory timings for 30.

Hi, thanks for the reply!

I had the newest adrenaline drivers installed. So, I Uninstalled them using DDU and then installed the blockchain beta drivers. After I do that, AMD settings window won't open and Claymore crashes during startup.

Then I reinstalled the adrenaline drivers and everything worked again (at 23mh/s). I changed the speeeds you suggested in Afterburner and the performance actually got worse (around 21 mh/s).

Any idea why that may be? Any other suggestions??

Thanks again!

In the next couple of days I will get 3x XFX RX580 GTS XXX 8GB, and I have a PSU Corsair HX1000.
The question is, do you think that power is enough to give what those GPU needs?

Thanks!

Overclocked my 2 RX580s draw about 430 tops tat the wall, I'd imagine you'd be okay

You might be starting off with too high of a clock change and the cards are rejecting the settings and reverting back to previous clock values.

My experience is that using the AMD Beta Crypto driver gives more control than Afterburner. I would say do these 10 easy steps for 28-31 MHs (Assumming your gear is working correctly)

1. Uninstall AB and remove the files when it asks if you want to keep them.
2. Use DDU to uninstall the current AMD driver.
3. Go to this folder (C:\AMD) and put all those files in a folder renamed to OLD.AMD.
  3.1 Go to system properties in Windows 10. See below step 3.1. This will keep your system from going back to the not crypto driver.
4. Install the Beta Crypto miner driver. When it asks if you want Relive choose yes.
5. If you have modded your BIOS you will need to run the pixelpatcher before you reboot. (very important step) If not modded just reboot.
6. When the system comes back up, don't start claymore yet.
7. Open the AMD driver and go to Gaming/Global/Wattman, accept the terms.
8. Change your fan temperature profile to to Manual. Set Max: 69 and Target to 58. Apply.
9. Go to the GPU speed. It's probably around 1300 or 1366. Change that to -12 or so. Get it to 1200 MHz
10. Go to the Memory settings and bring it up to 2100 to start. Hit apply. Run Claymore

Different cards all behave differently so I use this technique as a baseline. Some cards i have at 1200 GPU clock and 2100 Mem clock. Other cards are set to 1175 GPU clock and 2250 Mem clock but it really depends on your card and what memory type is installed on it.. Use GPUZ to monitor temp, GPU clock, Mem clock, and power draw.

Step 3.1- Right click the Start button and select Control Panel.
2. Make your way to System and Security.
Click System.
Click Advanced system settings from the left sidebar.
Select the Hardware tab.
Press the Device Installation Settings button.
Choose No, and then press the Save Changes button.

I've used these to help other folks out and it usually works out pretty well. I've found that after you play with the settings in the AMD crypto driver a little and you are not seeing any changes in hashrate, you need to restart Claymore. Sometimes you will need a reboot if you go out of range with your settings but usually restarting the Claymore batch syncs the cards to your specified settings... after every reboot check the GPU and Memory values manually by readjusting them again..
Another tip for rigs with multiple cards to figure out which card you are working on is to use GPUZ. When you change a cards core and memory values for identifying.. You can set them to something funky like GPU core 1275 and mem to 2050. Then look in GPUZ to find the card with those values. This will confirm which card you are working with.
Let me know if this helps.

Dude, this thread is already done for

not sure if you're only looking at titles

better read and check the posts

oh btw you have nice site out there
