sapphire RX570 8gb nitro + memory hynix.
these cards suck
they are not good for mining, I tried everything, all the timing, in all possible modes, the max to be stable 27.5 mhs
It might actually be your mainboard bottlenecking your gpu, one of my ud3 boards does this to me. That sapphire should go over 30 MH/s no problem. I'll post a rom for you to try out in a bit, see if that helps. update: Sapphire Nitro+ RX570-8GB (Hynix) Mining BIOSWarning untested BIOS!

how do I mod the bios for an ASUS Prime 270-A What can you accomplish with BIOS modding that can't be done with software? 1. You shouldn't need to mod your mainboard for mining other than updating your BIOS with the newest version. 2. Modding your GPU BIOS allows you to change the settings without installing custom drivers and kernels. Many mining apps have clock and voltage settings but are locked out by the drivers. Changing the memory timings for increased performance is also only possible made easier with BIOS modding.

Is it possible to have just the memory strap? That pastebin thing is useless.

Fellow miners, get your thens and thans in order and help other forum readers understand what you are writing. Remember the grammar basics: B larger THAN A (comparator operator). If something THEN ....

Sure I'll post a few later.
edit: **** If you click "download" on any ROM(s) I post from pastebin.com then "save as" a .uue file then extract the compressed .7z archive with WinRAR, WinZip, etc.. and the bios_file.rom will be inside the .7z. It works good don't complain, 10, 20 30??? years from now you'll be able to click on that link and it will actually work and you can download the binary file. pastebin...

you take an 580 4g elpida, copy the 1500 strap upper, set clocks to 1130/2000 and you have 29.5mhs out of the box. can't be easier.

Why did you include strap editor in your SRBPolaris if it was that easier? P.S. tRCDR/A should be equal, they weren't in ElioVP's timing 22/8 , had to be 22/22. Not a big deal probably to mess with you if you try to sell the timing( as it happened once).

I hoped more people will get involved in creating custom better straps, when it's all packed in a GUI but i was probably wrong, or they just don't want to share them. What i wanted to say with that 1500 copying is that its just as click click click, people should mod their own bioses, not use downloaded ones from the net, the chances to brick the card are bigger with those.

Of course...people see "hynix" here, "hynix" in gpu-z and use straps, not knowing that theres like 10 different hynix chips out there

Maybe I'll do Samsung and Micron another day. Any tips on Hynix?

r0, r2 and r4 you can only see printed on chips when you remove cooler...denotes 6, 7 and 8GHz speed I found out when I was looking for reason hynix is slower than micron on gigabyte rx560 cards...because gigabyte put r0 instead r2 so memory is already factory overclocked
