Title: rx 570 sapphire nitro - max eth hash
Post by: mrmactooo on December 09, 2017, 03:10:29 AM
Ive been modifying my memory straps but i only get 25mhs dual mining.
The cards are running on elpidia.
I have 12 cards running but I know it can do better than that. It sucks to know i could get 10% more.


Please help  :)

what is your second hashrate?
you can try different values of -dcri and detect the sweet spot for both of the hashrate
it is possible to get 28 mhs dual mining

I have 3 Sapphire Nitro+ RX 570 8GB (Samsung memory) and I am about to pull 29-29.5 dual mining DCR.

My dual mining average hash rate for ETH is 176mh/s and DCR is 3.8GH/s.

I did a Bios mod on the graphics cards after I backed up each of the memory just in case I needed to restore the original back on it.

I used Polaris One Click Bios to change the memory straps and then put that Bios back onto the card. (You need to only have 1 card plugged in at a time when re-flashing the cards so you can make sure you are changing the bios on the correct card since you said you had 12)


After you save your original Bios, make sure to move the switch on your card before uploading new Bios to card. (near the top, google it for pics)

Use the - or + while in claymore mining and you can change the dcri and find you sweet spot and also change your card clock settings using OverDrivenTool or through the Claymore config file.

good luck.

Man I need to know somethin, you're pulling 176 mh/s out of 3 RX580? That would be a whopping 58,67 mh/s per card.... Everybody on this planet succeeds in squeezing about 31 mh/s out of the RX580 hence I'd be interested to learn how you manage  to squeeze out almost twice as much?

I apologize, I should have put that I have 176 mh/s on my 1st rig. the other 3 cards I was referring to is my second rig I am slowly adding too. I should have reread my post before submitting.

My First Rig:
4 Asus RX 570 4gb
1 XFX 570 4gb
1 XFX 580 4gb

2nd Rig:

3 Sapphire Nitro+ 570 8gb
