No way what? There's about 50 billion guides out there, you couldn't find any of them?

I'm on a good mood, try these, hope it helps.

what i find is flashing with Hynix memory not samsung memory , and i am not sure that's the same (i am afraid to damage my gpu).....

the thread i posted above listed a samsung and hynix, RX580 most likely has dual memory, just follow those steps especially the backup BIOS in order to have a fallback once it messed up. its just a simple detailed steps intended for newbies.

at the "download BIOS" part of this site you will find modded BIOS for Samsung too... 

i had a problem of the size, the file given in the 1stminingrig(512kb) has a different size from the original one(256kb) extracted from my RX580 SE.
and the ATIFlash didn't accpted it ?????

Don't try to flash someone else's BIOS into your card. Open it in the PolarisBiosEditor and copy the stuff you're interested in from that one to yours (timing straps are the only thing worth copying, everything else you should input yourself).

do you think that flashing the RX580 nitro+ is same as the RX580 nitro+ Special Edition ?

You have to make sure you flashing the same bios version number what you have on your card...
On The screenshot you posted there is 2 totally different bios !

ok,and thank you

I also once had problems with this BIOS. I was looking for ready-made solutions but not found anything suitable. A friend of mine he edited the BIOS with an editor. It turned out that it is not difficult. Gives the effect better than any ready-made solution. How to make settings there are many videos on YouTube.

i tried to flash it with ready-made on for rx580 SE with samsung memory, but it didn't work
i got the file https://mega.nz/#!M4wFUJCK!HzXax2PDFGQA6-vyz4tACRCli1SVeidKxr4wTDgDYQ4 (https://mega.nz/#!M4wFUJCK!HzXax2PDFGQA6-vyz4tACRCli1SVeidKxr4wTDgDYQ4)

Your card has Samsung memory chips. Your link is to a BIOS with Hynix memory chips. ??? There's a lot of guides on how to edit your BIOS without downloading someone else's from the internet, and some of them are on this forum, including this one: https://bitcointalk.org/index.php?topic=1954245.0
Just spend 15 minutes and do it right.

sorry look well, the link give a moded bios for samsung memory as it's writen in the file https://mega.nz/#!M4wFUJCK!HzXax2PDFGQA6-vyz4tACRCli1SVeidKxr4wTDgDYQ4 (https://mega.nz/#!M4wFUJCK!HzXax2PDFGQA6-vyz4tACRCli1SVeidKxr4wTDgDYQ4)

Again, for the last time: the right way to get higher hashrates with AMD Polaris cards is to edit your own BIOS; the wrong way to do it is to download someone else's from the internet. The software will try to save you from your mistake by not letting you flash the BIOS from a different P/N — that's what's happening now. You might still act dumb and force the software to flash that BIOS by running atiflash in the command-line mode and with the "force" --f flag. And then there's a good chance you'll come to this forum again, saying that now all you get is a black screen when you turn on your PC.

Solution? Don't freaking do it the wrong way. Save your original BIOS with atiflash, open it with PolarisBiosEditor, edit it (put more aggressive timings in, lower voltage/clocks etc, although the clocks and voltage can be set with software as well, like overdriventool, so that's not completely necessary for now), and flash the edited BIOS back to your card. There's a link to a guide describing this all in detail in my previous post.

thank you for your help, but i discovered that my memory is samsung and hynix  when i edited it with SRBPolaris.

Will you just read the guide I gave you the link to? Or are you gonna keep ignoring it and coming here with the basic questions that are answered in the guide? You don't have both samsung and hynix memory on your card, read the freaking guide, it explains this very situation.

ok
