Yup, do not need

Added a "MAD SCIENTIST EXPERIMENTS" if someone want to help testing some weird (possibly not working and dangerous) mods.

Keep in mind:
  • I'm not responsible for any damage (of any kind) caused to you (or your card, your loved ones, your pets or everything that is related directly or indirectly to you) in any form/way/amount from using this bios mod (or my words) in any form/way/amount
  • I will not teach you how to properly flash a bios, recover from a bad flash and/or diagnose any kind of problem

I have the the Rx480 Nitro+ OC, but with 4Gigs. The bios is this one : https://www.techpowerup.com/vgabios/187623/sapphire-rx480-4096-161002
I haven't found any bios for an Rx580 with Samsung memory, it's still possible to mod it?

  • Downlolad my bios
  • With HxD (or similar) extract the VRAM_Info table from your bios
  • With HxD (or similar) replace the VRAM_info table in my bios with yours
  • Save
  • Open the bios with PolarisBIosEditor and click on "UPDATE CRC"
  • Flash
  • Profit

But could not work, you can easly redo my mods on your bios. Just read the thread biggrin.gif If really needed (an if you do not know how to do it) I could port this bios mod to your card.

Oh, great, i'm sure they come in crowds now! biggrin.gif

Maybe we should tell them how to unbrick their card. But we won't buy a new one if anything goes wrong or it's too complicated.. you should now what you are doing, even if we don't.

About the 3 VoltageObjects:

04 00 24 00 00 04 00 00 02 80 10 00 00 00 10 00 52 03 02 00 00 00 84 03 02 00 10 00 B6 03 00 80 10 00 E8 03

I don’t have a polaris gpu to test, but in my 380 that VoltageObject in my VOI and accordig to this post https://www.overclock.net/t/1561372/hawaii-bios-editing-290-290x-295x2-390-390x/2530#post_25102436 is like this:

04 00 24 00 00 04 00 00 00 80 10 00 00 00 00 00 39 03 00 80 00 00 B6 03 00 00 10 00 CF 03 00 80 10 00 4C 04 <--04 VDDCI + 00 GPIO LUT voltage + 24 usSize + ?

These values are the same values I see in the powerplay near to the memory clock named like VDDCI. So it could be some thing related to VDDCI.

I see at this 7950-7970-bios-mod-thread: https://www.overclock.net/t/1395490/ati-hd-7950-7970-bios-mod-thread , that they are using a GPIO LUT voltage table related to vddc and other HIGH_STATE_ LEAKAGE_LUT related to vddc on Voltage Objet Info table, to unlock vddc voltage.

@kahboom said there that: "there are two spots here one is the voltage you would see in a tool utility and the other is the cap".
But I don't know what is the "cap" value and the "voltage you would see in a tool utility"(I don’t know what it means):, and the LEAKAGE_LUT table is not present at 380 VOI table, so I don't know if it’s “capping vddci” or it’s "voltage you would see in a tool utility".

Warning: Spoiler! (Click to show)

Now in the image above i have edited both the values to 64 05 which in reverse is 05 64=1380 in decimal value or 1.380v now for the software test.


Notice the image above the value for the GPU VDDC third column the max voltage is the new value, and card is throttling according to the ASIC i set for load. thumb.gif

If you are feeling brave enough to try remember to edit the checksum to avoid conflict.


I will try to test it and see if it's doing some thing.
