i have 2 rx 570 4gb red devils

when mining ethash i get around 27m\s on both of them

1200-1950

but mining cryptonight

1 of then ash at 750h\s and the other one 450\h\s

i tried to play a little bit the cc and mc but 450 is the best i could get

anyone could tell me what's wrong ??

and can i pull more than this from this card Huh

my power consumption around 125w which's consider as high

my PSU: cx 750 w corsair

thank you in advance

so my problem got fixed my problem was that you ahve to change the setting to compute mode for all the cards i thought changing one makes the rest also compute mode

any way got it fix sorry for my bad english :D

and thhx for the people who tried to help :)

I have a lot of Sapphire RX 570s  all 4Gb, Hynix and Elpida.
They all do 29.5MH/s no problem.
I am mining Expanse or Musicoin, though.
Minining Ethereum the hashrate drops to ~28MH because of the larger DAG file.
My rigs are Win 7 or Win 10.  
No overclock.  Core/mem at 1100/2000.   BIOS modded to tighten mem timings and lower core voltage.
Using WattTool 0.92 to control freqs and fans.

EDIT: I have a rig with 4 of these cards. The PSU is AX760.   Rig is drawing 465 Watts dual mining Exp/Xvg
Mining Monero the watts drop to 395 for the whole rig.   Monero hasrate on this rig:  3250 H/s  

27 mh/s is a bit to the low side for the 570, what driver are you using ?

Ehh.... some of my 580's catch around that hash rate, that kinda makes me wonder a bit. I thought that was pretty decent to be honest.

Try to give those "lower Hashrate" card a dummy output. In most AMD card, dropping Hashrate is one of a regular issue.
Or may you need to test it first to disable one by one? Try the first card and disable the second card and so on. Just to make sure.

I'm hitting 29.8 mh/s mining crypto stable with 6 Sapphire RX570s.

I'm able to hit 32 but it crashes about every 30 minutes, so I dropped it down to a point where I rarely crash.

im using adrenaline driver  andi moded the cards the simple way copying 1500 strapss

can someone help me with this plz!!!

'


can you share your settings plz


and what's ur power consumption ?

no soluation anyone ??? plz :(

It's hard to follow exactly what you are saying, so forgive me if you already answered this.

What mining software are you using for cryptonight?

im using claymore for cryptonight i tried GGS same thing 1 card 750 and the other one 450

but mining ethath they both do 27m\h


driver adrenaline

1250\1950

PSU cx 750wat

windows 10

Sometimes when you close one miner and open another the overclock on a card will get reset. Are sure they are both set the same?

Have you tried a different miner like xmrig or xmr-stak?

im sure about the overclock coz i tried to change i was hopping to get higher than 450h\s

i didnt tried xmrig or xmr-stak


but i tried GGS for cryptonight


my problem is why when mining ethash both cards give 27m\s and when i change to cryptonigt one of them goes realy low 450h\s for rx570 is shit i guess... :(

.....

well have your flashed modded bios to your cards?
my rx570 from asus with modded bios and with these clocks 1165 core / 1950 memory can make around 900h/s in cryptonight
which is almost 2 times less then vega can push
while mining eth with these setting the card is giving 29 mh/s, so your number a little low. so maybe you have to flash the modded bios?

I had the same issue with one card. I have a rig with 6 rx570's and all of them were doing around 29 mh/s except for one card the was doing ~20-21mh/s.  All of them had the same core, memory and volt settings. So what I did is change settings for that card only.

I changed the core from 1120 to 1150, memory from 2050 to 2010, and volt from 900 to 970. Now that card is doing around 28-29 mh/s like the others. The only difference is that card is running a little hotter than the others because of clock and volt settings. Hope this helps.

I thought your problem is:

but mining Cryptonight
1 of then ash at 750h\s and the other one 450\h\s

Focus on your main problem first, seems you don't have an issue on Ethash, those two cards, do mining with the same Hashrate on Ethash. Did you try my suggestion above?

yes i moded bios my cards those hasrates all after modding
would you mind tell how did you moded bios what did you use ???

i just copied the 1500 straps

oh no on ethash bot cards do the same


but i didnt udnerstand what do you mean dummy output !!

dummy output means output display, didn't need to be connected to a monitor, HDMI adapter is enough.

 I dunno, I've got 3 red devil 570s, and they'll do 29 at best, and just not stable any higher. I think sometimes a solid high 20's is better than a 31.6 that crashes an entire rig every few hours...

If you've done what I mentioned before and didn't fix the problem, make sure you're not connecting your monitor to any of your rx570s. Connect your monitor directly to the motherboard integrated graphics.

i should get the adapter i guess to connect it to the MOBO i dnt see any HDML pot in my MOBO

I see. So your motherboard doesn't have integrated graphics. What you can do is install teamviewer on your mining rig then disconnect the hdmi cable. This way you can access your mining rig remotely and see if unplugging the hdmi cable fixed your problem.

ill do it and come back to you thx for ur time

If your plan is to control your rig through Team Viewer, you need output on one of those cards (if you set as primary display), so the system will be working on the right resolution. If you didn't plug any output, you will get the small display and maybe dropping your hashrate (AMD cards issue).

Plug dummy output on a card with dropped hashrate.

Tips: just quote the point would you replying or asking, don't quote all of the posts.

some guy said it his core/mem at 1100/2000, and no overclock, how it is posibble, cause factory set core and mem are different than it, 

it can be bios mod, (modified bios)  but modifining the bios is the same thing with oc on afterburner, isn't it ?

thank you for your answers

With bios modding you can change timing straps, volt, memory, and clock settings they will be stuck on the card with every reboot and operating system. However, with AMD afterburner you can only adjust volt, memory, and clock settings and the program will apply those OC settings with every reboot (if you have that option enabled).

OverClock, and bios modification is a little bit different.

Bios Mod
Changing default bios condition to something that we want. After modified the bios, still we need to do a tune-up (Overclock, Underclock, Undervolt..etc) until we get stable setting using tuneup utility such as After Burner.

OverClock
Increasing clock rate from the default setting to the higher one, using tuneup utilities.

well said

i hate team viewer  is there anyother way ??

or a fix around i mean maybe im ok with 750 but 450 is so low :(

I didn't suggest you use Teamviewer, just trying to clarify what Mo20 said before, Mo20 suggesting you use Teamviewer without any output on both card, and I told you will get small screen because those cards will not produce the right resolution.

I suggest you use a dummy output (HDMI or whatever adapter) in one of your cards with a small Hahsrate. Adapter only, don't need to connect to monitor. Have you done what I suggested before?

I don't know what else to recommend. I use SimpleMining to monitor and control my rigs. Hope you find a solution to your issue.

problem fixed thank you all for ur time i really appreciated it :)


how didi fix it !!

i didnt know that i should change to compute mode in all the cards i thought changing it once and it will change for the all cards how stupid IAM right :D  anyway problem fixed and im happy again now :)

Glad to hear you fixed it.  ;)

You did a right thing with updating this thread, so another member with the same problem would be more accessible to find a solution, may you need to add your way to fix your problem on your OP.

DONE
thank you so much for trying to help
