Re: Low hash rate with 2 RX580's

So I've been playing around with this for the last couple days and still haven't been able to get past 22 my/s on the red dragon card. Anyone else deal with something like this?

What cards you have? rx470, rx480, rx570, rx580? (both RX580 right?)
What memory size? 4G, 8G?
What type of memory does the cards have? Samsung, Elpida, Hynix, Micron?

Both are RX 580's 8G. The Red Devil has Samsung, and the Red Dragon has Hynix.

I really for the life of me can't figure out what the issue is.  I'm trying to set up the Red Dragon itself.  I copied the timings from 1500 to everything under it, yet it's still hashing at the same rate.  I even copied the 1750 to 2000 as well.  When I try to raise the memory clock up to 2100 it goes DOWN.  This is one ETH mining only.  Maybe I got a bum card?

Got home and played around with things a little.  I started with the Red Devil card.  I verified that the straps were set correctly.  I was able to get 29 mh/s with this card by itself!  Core was at 1100, and memory at 2100.  Upping the memory to 2200 seemed to drop hashing down to 11?  

Then I moved onto the Red Dragon.  It looked like I missed changing the memory straps on this one.  After making the changes I tried mining with it alone and am only getting like 18 mh/s Sad.  Looks like the memory is Hynix?  Is that the reason it hashed so low?

I might have to just sell the Red Dragon I guess and try to find another Red Devil.

ETA:  The Red Dragon seems to be all over the place with the hashing power.  It varies from 5 to 18.

Thanks for the suggestions.  I'll give them a try when I get home.  The RAM on the cards I have is Samsung.

I tried your suggestion and lowered the intensity for sia.  That seemed to help a little, but I'm not able to really get over 48=50 mh/s.  I've tried upping the memory clock, but I seem to get a BSOD when I push it up to 2200.  Anyone have other suggestions?  I'm currently mining just ETH, and still seeing the same hash rate.

Hi all. I just set up a couple GPU's in my PC (figured I'd start small before jump into a 6 GPU mining rig, and you can't find cards anywhere). Right now I'm pulling 45ish Mh/s, but after researching I feel like I should be able to get 55-60. I've already done the bios mod (changing the memory timin I believe). I followed a couple guides, yet when I down clock my core clock, and increase my memory clock I only get 11 Mh/s per card. I'm not sure what steps I'm doing wrong. Any help would be greatly appreciated!

ETA: sorry, forgot to add some info. I'm trying to dual mine using Claymore (latest version) ethereum and siacoin (my siacoin hashrate is 1400 Mh/s, don't know if this is good or not). I'm on 17.4.4 AMD drivers. I'm pool mining on Nanopool. And the cards are both PowerColor RX 580's. One is a Red Devil and the other is a Red Dragon.

your SIA intensity is too high, decrease it and your ETH hashrate will go up.


Awesome, thanks for the info. I'll give that a shot when I get back home.

Will that also help when I change the core and memory clock speeds? I'm hoping to decrease my power usage.
