Sapphire radeon rx 570 4gb bios mod help (reward)

[tgejesse]

Hey guys, I've been messing around for a day now trying to get the time straps to improve my hash rate, and the best I could get was from 24-> 25 mh/s. I'm clearly messing this up or doing something wrong. I will be willing to donate for some assistance getting these up in the 29-30 range where they should be. PM me here or contact me on skype: tge.jesse

Love you all!

That is the original rom and the memory type is Hynix

copy the 1500 straps and set the default memory frequency, make other changes as you please.

I've done that and the best I could get was 1 more mh/s. I'm not sure why.

Lately too much threads have the word "reward" in their title

You need to set the default memory frequency in the bios.

If you set memory frequency in a OC tool like afterburner the memory does not actually change (even tho it lies and says it did)

When you say 1500 is that 1:1500 -> 1:1650, 1750, 2000 or 2:1500, 1650, 1750, 2000 or is it both 1: and 2: ?
People keep saying 1500 but I'm not certain what one they mean by that

[doktor83]

They mean you need to click on the "Strap 1500 to upper" button, and the magic is done for you automatically.

Oh thank you, the editor below was the one I was using, but this one looks much easier to use

i know, i made that easier one , for the simple man

You sir are a legend. I've managed to get it up near 30MH now, however, I am uncertain about how many GPU Memory Errors means it's unstable, at about 5 min it's had about 1000 errors, but I have not gotten any warning from the miner yet

[doktor83]

you won't get warning for mem. errors from the miner
Test the card by letting it work for 24h. If it survives 24h its good and stable

Hmmm, well the errors im referring to are the ones reported by HWINFO, after dialing it back to 2025 mem freq then they no longer occur at the cost of Hashrate of cause , so you are saying these errors don't matter?

well it looks like they don't really affect found shares, or not in a way i'm aware of.

Interesting, well for now I think i'm gonna stick to a freq without errors which the highest I can get is 2075 which gives me 29.6MH when I use a core voltage offset of -96. Thanks again for the help

Omg, did you get to that with sapphire Rx 570 4gb??? How did you get it???
If you use the same GPU, could you pass me the BIOS? Or tell me how to edit original BIOS please
