Was able to get out of the 28Mh/s range and back into the 30+ range. It wasn't as easy as install and go as the new drivers take a bit different speeds. I had to drop my GPU core clock to stock (1200) and I could still max out the memory as long as stable. This new driver also allows for lower power consumption. I'm just shy of 200 W less overall on my 8 x GPU rig.

RX series timings txt file - thx to Mattthev.
I have 6 saphire nitro+ rx580 8gb with micron memory on my rig...when I conect any card, it hashes little over 30mh, but when I connect more then 3 cards, total hash rate drops on 26-27mh per card...do you know what seems to be a problem? Motherboard is biostar tb250 btc
GRATON I had a similar issue with this when running Windows. I had to start over. Wipe all drivers with DDU and then install one card at a time and check hash each time before moving on. Also, make sure bios setting are optimized (gen 2). If still not working try swapping risers and cables
I believe another user tried it and it did. If you open up that RX timing txt file you should see some 570 timings. You can always just try it out. If it doesn't work better just copy back your old bios.
cheers dude, im following, im trying to snag cards as they come available for a decent price, so far 2 1070ti and 2 rx 580 on their way, giving myself an excuse to buy more amd and nvidia cards so that i have 2 complete rigs by summer lol :D
Pascal De Ladurantaye for long term I would stick to the 80% rule. But 750W PSUs are cheap enough it might not matter if it fails a year or two quicker. If you watch my other video of this rig today I'm running 750W PSUs
Need your help I will bulid my first rig I have 3 nitro Rx 580 8 gb. So how I connect them to the power supply using the 6 pin or 8 pin or both and how mush power the 3 need I have 850 watt power supply
LOL! Yeah I was really new to your site back then. Thx! for all the help. When dual mining still have the same consumption. Here is the updated video: https://www.youtube.com/watch?v=4gJ1_YLfCoM . I just stopped mining SC due to the recent ASIC caused difficulty hike. I am getting about 575-580W on each PSU now that brings me to a total of just under 1200W
Hello, miningmadeasy, great videos and I've learned a lot from you. I have a quick questions, I'm running 6 RX 580 Nitro+ and getting around 180 mh/s, but the other day my Windows complete broke and the rig shut down. Do you have any clue, which can help me what is causing an issue like that? I'd really appreciate the help. Thanks and keep up the good work!
Does your machine keep rebooting? Or does it no longer come on at all? If completely dead I would start with your PSU, then mobo. If rebooting try unplugging all your cards and see if the problem persists. If not, then it is a riser or bad riser cable.
This is a very similar build that I am in the process of putting together. I noticed that you've only used the 8 pin power connector for your Sapphire GPUs . I've read lots of different opinions on weather to use only the 8, or the 8 and the 6 pin combined to power the card. Any thoughts on weather to use 1 or both? One concern I read was that if you're overclocking and only using 1 power connector, then you could run into issues without having the second.
If you are pushing these more power than stock, yes I would suggest using both connection. I'm undervolting these to where each card is only pulling around 75W. One power connection is totally fine. If you get above 150W pull then I'd suggest using both connections. It has been running since July just fine with one connection.

I really like your system at the same time it looks beautiful visually. I have a few questions. Did you recommend a this motherboard and did you ever get a problem? Some users say they are having a lockup problem. I am thinking of using 2 pieces of 850 watts fsp G850 as power source for 7 cards. Will that be enough? (Sapphire rx580).Finally, what are you using ram and cpu? Thanks for the video and sorry my english :))
Yes. The Asus Z270-A is one of my favorite boards. It also runs 12 x GPUs very well. 2 850 PSUs should be enough for 7 cards. I will be posting a new video on this rig as I have since moved this into my mining room. If you have yet to subscribe and hit the bell. I'll be posting it here in the next few days.
seriously thinking about buying 4x of the same brand/model 580 8gb cards in your video. is that as good as it gets? like 729 watts for about 120 MH is some serious power draw (current get 220 MH for same power on nvidia). was hoping that could get around no more than 500 watts for 4 card or am I dreaming? is it possible to mod these to be anymore power efficient . i dont mind going to 28mh per card, only if could mod them down to way lower power? price of these card make more sense over nvidia (cannot keep buying nvidia, price to high), but price per kw is super high where i am. let me (anyone) know if super low power can be done?
cycobee AMD just draw more power. They do this through the riser. 150W GPU+riser has been the lowest I've been able to manage. I was able to get this rig of 8 cards down to 1100W total since this video was posted.
Nice video man, i have 3 rigs with 6 RX570 8Gigs each, i only get 146Mhs per RIG, i don’t know why. Once i got 180 MHs and can’t find that mV again to play with clock’s a bit. Anny sug.. will help here. Thank you
With only changeing the memory straps on 570+ you can get up to 30.8-31 Mh/s With +10 Frequency +2200 Mhz Max (SAMSUNG ONLY) Consider When the Dual Minrr will start you will press "-" untill you set second mining from 30 to 1 WITH OR WITHOUT USEING IT SE IT TO 1. it gives you +0.500/0.800 Mh/s more
You just need to download Polaris Bios Editor, you can find the download link at 1stminingrig.com in the description. Once in there replace the mem stratp timing with the ones that match your card from the txt file I provided and drop the max voltage for mem and core to 950. Download ATI WinFlash (same 1stminingrig link) to flash your bios (make a backup first).
miningmadeasy i used 1750 to 2000
I’m using 4.4.0 beta 16. I dont know how to overclock RX cards, just by using some tuts found in youtube.. if you can please make a video on RX570 4GB elpida and 8GB hynix cards. Thank you so much :)
Give it a shot. Worst case scenario is that is will blue screen. Most of the time the miner will just crash. I just added to the description a download link for some timings that are really good to pull from when trying to find a good mem strap. I think the mem strap I'm using was actually from an old 470 or 480 thread.
I've been on that version since it was released. I've seen this as an intermittent problem. For the longest time, I was never able to unlock the slider. Then, out of nowhere, it was unlocked. At some point between now and then, it has locked itself again (despite being on the same version). So that's why I was interested in seeing any screenshots and/or config details.
Use DDU and remove all drivers and then plug one in at a time. Make sure you wait 10 minutes or so between each one to make sure it fully installed. Windows can support up to 8 x AMD and 8 x NVIDA. So at most 16 GPUs but only 8 of the same architecture.
