Modified GPU BIOS for Mining

[tadeus1]

jaschaknack PolarisBiosEditor v1.6.4 would do for editing. Google.

Save current BIOS to file.
When you open the bios with Polaris Editor, look top right drop down and see which digit is for Elpida memory. There would be 1 and 2. I think its "1" for Elpida, but check it out.
Try with 1:1500 values and put the value into the higher fields for 1:1750 and up to 1:2000.   
Change Core voltage if you want based on core Mhz categories. Don't go super low.
Save. Upload to Card.  Patch driver if needed, reboot.

Thanks!

any ideas about which ETH Mining speed is normal for this GPU?
in a other topic peaple speak around 22mhs but it is very slow...

i will test it...

[tadeus1]

Should be able to get 28 at least.  22 is usually the default without any mods.

[OverEasy]

I have managed to get a stable 28 mh/s on Claymore but am now facing an issue I have never seen or heard of.
I have 2 identical cards flashed with identical roms. (ASUS RX570 4 GB Elpida)
Windows 10 x64
AMD blockchain and latest drivers (tested both)

Full safe mode DDU, new AMD drivers, Patched and here is the issue -

ONE (either) will run very nice and stable.
TWO cards crash rig almost instantly.

So I changed MoBo's and got SAME issue.
So I changed ports, I changed everything!

Right now I have one of the cards mining away happily. If I shut down and plug in the second card the rig stops.

Not the MoBo (tired 2 different ones)
Not the cards (both work independently)
Not the risers

So what the heck?!

Any and all suggestions welcome.

[tadeus1]

What about Power supply?

I'm still new to these 570s and they're not as robust as 580s so bear with me, I'm testing out stable mods right now and I'll post bios' for select cards.

i wanted sed you my bios but my rig is far i control with teamviewer so i cant use atiwintool for extract the bios of each cards because is not diplaying more than 3 cards.
can i send you original bios from web site? i know exact model of cards

Just enter "[the model of your card] + bios" into Google and it should return a techpowerup link on the first page.

sapphire rx 570 nitro+ OC 4gb

at the moment i push my hash rate from 22mhs to 27.5mhs.
i copy my 1750 stripe to the higher one and set the points in simpleminingOS

- mem clock from 1750 --> 2200
- gpu clock from 1340 --> 1150

other ideas to improve my performance?

- use a other stipe?
- use a complete other bios?

i are open for other things :-)


Best regards
Willi

What memory type? You should probably get 29.5-30.5 range regardless, its just that copy/paste straps
is not ideal

[willi9974]

Memory Type is "Elpida"

[SnOOpeRa]

sapphire rx 570 nitro+ OC 4gb
- mem clock from 1750 --> 2200
- gpu clock from 1340 --> 1150

Are you sure your elpida memory is running 2200mhz from 1750mhz stock , I do not see elpidas to go so high , you have to use some very loose timings. With eliovp elpida strap you get at 1150core/1950mem about 28.5+ mhs eth , higher clock the memory higher the hashrate.

On some 470/570 4gb elpida 1750 and 2000 straps are the same , using eliovp strap which is based on 1500 strap ( with some small changes ) on 1750/2000 straps will give you boost to go to about 30mhs depends of the lottary how much high your memory clock without errors.

[tadeus1]

willi9974  my suggestion was to use 1500 straps. Try with that and not with 1750 strap

[willi9974]

At the moment i have 171 MHs by 850 Watt
1500 strap, 2100 Memory clock,  1100 gpu clock and a 900 undervolting

 I hope the Rig run stable:)

Is it stable?

[notbatman]

Sorry folks but these RX570-4GB cards are terrible, I they just won't run overclocked stable and/or without errors unless you get a lucky card.

[willi9974]

perfekt and yes my cards run at the moment very stable

Code:

ETH - Total Speed: 171.640 Mh/s, Total Shares: 824, Rejected: 0, Time: 07:22
ETH: GPU0 29.010 Mh/s, GPU1 28.994 Mh/s, GPU2 28.973 Mh/s, GPU3 28.990 Mh/s, GPU4 26.722 Mh/s, GPU5 28.951 Mh/s

Interesting that you can achieve those number coping just the 1500 straps, I've not seen such a boost without overclocking the VRM + custom straps and that causes problems on these 570s.

In any case I'm done messing with these cards, I've got my two rx570 cards going like molasses in January @ 581 H/s XMR. My 480/580s on the other hand run at 1k H/s.

willi9974 do you have sapphire RX 570 nitro+ 4go with elpida memory ?

Can you share your bios with me ?
