You can look on the first post to the Mega link... he has some TMod bios for the Nitro.

Nice to meet you all!

I tried a lot on the timings of the Fury X.
And this is what i have with 1.325V on the HBM using the last Official Bios with HBM Voltmodding via HexEditor.

The Graphics Card is on 1100/500

Thats it.

See ya

here are the main things to do:

-Find the bios: i used the latest "Sapphire R9 Fury Nitro" bios on the TPU database > https://www.techpowerup.com/vgabios/...ry-4096-160720

-Use ATOMBIOSReader to read/export the tables in the bios > the memory related one is > " 001c: a82e Len 02c3 Rev 02:02 (VRAM_Info) "

-The table start at offset "a82e" and the lenght is "02c3"

-Open the bios with a hex editor (i like HxD) and find/select the table

-This bios has support for Hynix memory and contains 4 straps > 100-400-500-600Mhz (under "BIOS Internals" in the TPU bios page and at the beginning of the "VRAM_Info" table(H5VR2GCCM_1_3V))

-Now let's find out what hex values we are looking for (https://www.binaryhexconverter.com/h...al-converter):
600Mhz +00 = 60000 = 00 EA 60(Hex) > 60 EA 00(flipped) < we will find this at the beginning of the strap
500Mhz +00 = 50000 = 00 50 C3(Hex) > 50 C3 00(flipped) < same as above
400Mhz...
100Mhz...

-Now look for the "60 EA 00" and "50 C3 00" straps in the table. All the informations between 500Mhz and 600Mhz are the 500Mhz strap's timings (Lenght: 28)
500Mhz Strap (A948) > 50 C3 00 00 08 21 34 16 E0 24 AA 00 14 63 6C 44 40 01 00 00 AD 2A 38 0C 73 29 2A 0F 08 08 0E 0E 35 06 15 0D 00 10 42 08
600Mhz Strap (A970) > 60 EA 00 00 08 21 34 16 E0 24 AA 00 14 63 6C 44 40 01 00 00 AD 2A 38 0C 73 29 2A 0F 08 08 0E 0E 35 06 15 0D 00 10 42 08

at this point change what you want and save the bios, fix the checksum and flash it. DONE. Easy easy
