Modified GPU BIOS for Mining

[notbatman]

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 BIOS

Warning 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.

Regarding 2. No it's not only bios limited

Is there an app to change the straps dynamically?

[bobben2]

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

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...

1. Samsung -> messy, too tight raw refresh cycle time(tRFC).
2. Hynix 8G -> absolute mess
3. Micron -> not that bad but might be better( at least timings are correct(actrd a bit low))
4. Elpida - ElioVP Timing( it has incorrect value, probably on purpose -> 777000000000000022AA1C00315A5B36A0550F15B68C1506004082007C041420CA8980A9020004C 01712262B612B3715 -> Fixed! )

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

Actually not that much
    { 0x6, 0x6, "SK Hynix H5GC4H24AJR" },
    { 0x6, 0x7, "SK Hynix H5GQ8H24MJR" },
These are the ones that are commonly used in polaris GPUs.
@doktor83 you are right about stock vbios modification but since you can't beat them you become them / hard to explain to ignorants  that you modded your/his own bios /.

theres also H5GC8 series...then you forget most important thing...R0C, R2C and R4C at the end

Thanks dude, it was a lot of work flashing and re-ordering all my Elpida cards. Maybe I'll do Samsung and Micron another day.

Any tips on Hynix?

[laik2]

Its getting hot very fast, that helps enough.
@Branko I guess I was lucky to have polarises with only those 2 lines I wrote in my previous post.

I have a Sapphire Nitro+ RX 580 8gb Hynix and I'm barely getting 700 h/s xmr. What can I change?

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
