Topic: [SOLVED] Modding RX 570 Sapphire Nitro+ (Read 15577 times)

I am getting 30.5-32.5 with no rejected shares. I made a write up and shared my bios file here.

https://sites.google.com/view/taylormining/home

I just built my first miner with 2 of these cards. 1 had HYNIX and the other has MICRON memory. Any bios files or help you can provide would be great and appreciated. I'm averaging 23 m/hs between the 2 of them and I know there is quite a bit left on the table.

Thanks

Nice! Thanks Hag. I had looked around on anorak but couldn't find the silent. Nice find.

Thanks but they don't have the nitro+ 570 8GB. And I need the Silent bios.

Search for your card here:  https://www.techpowerup.com/vgabios/

They have a great database with almost all of the recently released GPU VBIOS in it, just be sure to pay attention to slight variations though as many models will have different revisions.

Help! I wrote over the Silent bios for my Nitro+ 570 8gb Hynix card. Does anyone have a copy? I really need it!!

@Berque: After several hours of tweaking, reinstalling drivers, and experiencing cool OC crashes (this is my first time) I finally got some pretty decent speeds. Not really 29-30 that I was aiming for. I have the 8GB card with Micron.

The only Bios edit I did was copy 2:1750 to 2:1875 and 2:2000. Do you know how to do it yourself? I'd share the file, but can't see how I attach something here..

GPU Clock: 1135 Mhz
Mem Clock: 2249 Mhz
Volt: -150 mV
Power usage: 95W (GPU-Z)
Temperature: 62C

Hmm, it was running stable at 27.2 for a few minutes, but now it fluctuates between 21-26.6. I'll leave it running for the night to see what the average becomes. Now it's up to 27 again. Kinda weird. Does anyone know why? I'm using Claymore.s.Dual.Ethereum.Decred_Siacoin_Lbry_Pascal.AMD.NVIDIA.GPU.Miner.v9.7.

Good luck and let me know how it works out for you!

I have bricked my OC bios with a bad image, tried a few bioses but they were not so good. So i had to go back on backup, standard bios...
Can someone share me a good bios for RX 570 Nitro + 8gb Micron memory?
Thanks a lot!

Hi to all, i just want to re-up this thread, if someone has their settings for AOURUS 570 kindly share ur settings here.. Thanks

In the last few days I set up an rig w/ 8x Sapphire Nitro+ RX 570. I'm pretty disappointed with them. @ stock I get ~24mhs running at nearly 1700 watts. Micron memory. Which is pretty normal, issue is with the overclocking.

I tried Windows 10 first, got them to work using a driver fix but couldn't adjust the memory/core clock settings in Trixx or MSI Afterburner. I also tried modding the bios, no luck, either ended up crashing in Windows 10 or there was no change in the hash rate. So I reverted back to the original bios.

Gave up in Windows 10, tried ethoOS, could not get all the cards to recognize. Tried PIMP, same, issues getting all the cards to recognized. Tried 1 card at time, followed typical troubleshooting steps, motherboard bios settings, risers, etc. No impact.

Then I tried Simple Mining OS, just because I was frustrated I started out with all 8 GPUs, and to my surprise they were all recognized the first time! How nice.

The best I can get now, using the overclocking settings in Simple Mining OS with all 8 cards is ~197mhs running ~1150 watts. Kind of sad. Have a few rigs each running 8x GTX 1070s in Windows 10, have no issues getting ~239mhs @ 1200w.

Here's what I'm using. I ended up having to adjust each one individually, they're all acting different. I could not replicate the ~29 mhs I'm getting on the last card with any of the others. If I run at stock settings hash is same as Windows 10, ~24 mhs @ 1700 watts. I might have to tune my last card down a bit too, is freezing once in awhile.

At this point I'm just tired of messing with it. Maybe it's user error, but I kind of think it has something to do with these cards. Don't have these kinds of issues with my GTX 1070s. I'm going to try my next batch of GTX 1070s in Simple Mining OS, if all goes well I may move my existing Windows 10 rigs to it.

Core/Memory/Mhs
1025 / 1750 / ~23.75 mhs
1050 / 1750 / ~23.75 mhs
1075/1850 / ~25 mhs
1075 / 2175 / ~24 mhs
1075 / 2150 / ~23.75 mhs
1075 / 2150 / ~23.75 mhs
1075 / 2150 / ~23.75 mhs
1130 / 2150 / ~29 mhs

How is the Micron? I don't have them so I'm curious.
27MH/s for Samsung is pretty low. Could be 29+. Use performance timings or PM me.

I've successfully modded the BIOS so it works stably at 27MH/s when mining ETH. I used SRBPolarisEditor and replaced the 2:1750 straps with 2: straps above. Set Mem Clock on MSI Afterburner to 1140 and Core Clock on 2000.

Working stably for 2 days now.

Mine RX Sapphire 570 Nitro+ has Samsung and Micron memories. 

Cool, thanks.

Just a quick question, which one is better to have for mining ? Samsung or hynix? (And if they are known cards that have particular memory chip inside)

No it should work with either.

thanks alot for the share, but i am abit confused.
if we take for example this card the 8gb one https://anorak.tech/t/sapphire-rx-580-nitro/5017

it says Hynix Samsung, these are 2 differents memory chips, it wont cause a problem using the same rom for the different memory chips?

Took  look at this and it only has one with a strap which is like 1 click anyway and another with strap and core clock turned down
