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

nice to see you got that can let us know what you did me too stuck at same place

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 Cheesy

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

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

here is a editor

https://bitcointalksearch.org/topic/srbpolaris-v35-bios-editor-for-amd-rx4xx-and-rx5xx-cards-1882656

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

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

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

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)
