Creating BIOS HEX Editing guide & Tips/Downloads GCN etc. I will Post Here All known BIOS/MODING releated tools: Also some Really Great Tools for Fiji HBM architecture Made by Radeon Community in overclock . net # AtiWinFlash_126.96.36.199 # Fiji_BIOS_Editor_v1.2 # Atomtool_v11 # Cuinfo_ver16 # R9 Fury Unlocking with Simple How to ReadMe + Python_2.7.12_amd64 All files are here for Fast Download (for Updates you need to go to the overclock . net Forums) My Fast Mega Downloads (All files Here) I manage to add Unlocked V BIOS Edit Ready (no UEFI): Fury-X NANO Pro-Duo NITRO OC+ TriX BIOS ========================================================================================= Here you can find Guides for Moding your Radeon GPU R9 280, 290, 380, 390 Fiji Arch. Fury-X, Nano & Fury-Pro overclock.net amd-ati ========================================================================================= I need point to start. I wanna Edit Mem Timings, in short i need to tighten it up RAS/CAS etc. Give me some advise. And i think lot of people will be happy with Our Guru3D Thread for BIOS HEX Editing. 1. Save BIOS (GPU-Z, VBE7 0.7b etc.) VBE7 - vBIOS Editor for Radeon 2. Download Hex Workshop 3. Find strings then change. 4. Calculate BIOS checksum before change and after, then make it right. or Easy way -> Open Edited BIOS with VBE7 and save it (checksum corrected ;-) ) ========================================================================================= Some usefull Tools for AMD/ATI: The Stilt's AMD "Extreme" Tools - APU Fuse Interpreter ("AFI"), latest version: R1.02 - BullDozer Conditioner ("BDC), latest version: R1.0.3B - Devastator PowerTune ("DPT"), latest version: R1.00 (unzip with 7-zip) - Trinity Control Interface K2 ("TCI K***65533;"), latest version: V1.1 The Stilt's AMD "Extreme" Tools Collection Tahiti GDDR5 Identifier http://www.techpowerup.com/downloads/2326/asus-radeon-memoryinfo-1-005/ And here -> My Space in MEGA - lot of stuff there ========================================================================================= HBM voltage Fiji Tweak for Nitro OC GPU's ROM must be with HBM voltage registers and its without UEFI support. Don't Set more than IIRC 1.350V this is IMO Safe spot (1.400 will work but Temperature of HBM must be in check !) Every ROM in that pack offset location AD0E is the data value for HBM voltage offset. So we are always editing offset ad0e: So you make the 00h as you require, 01h = +6.25mV , 02h = +12.5mV and so on. Example: 8E 00 00 00 is +/- 0mV , to have +25mV it will be 8E 00 04 00 and you'll Have 1.325V HBM Like here on screen: Spoiler ROM Pack for Sapphire Nitro OC+ 1050/500 also will work for NITRO 1020 & 1040 :nerd: ROM Downloads, if you don't know what you are doing -> Don't do it :no: These ROMs are great for CU's Unlocking ! These are stock 3584SP ROMs, You need to run atomtool on ROMs and you will get 4096sp/3840sp/3776sp to play with. NitrC_0mVTMod.zip Download (i've Tested those ROMs and its Safe to Play with it) Gupsterg Notes: After flashing you must power down card so IR3567B is reinitialised with bios data. 1). Enhanced protection ROMs, so MAX VID for GPU or HBM is 1.36875V. 2). These are Non-UEFI ROMs so CSM support must be on in motherboard bios. 3). If you use software OC tools in OS delete these prior to flashing ROMs and do not keep saved "profiles" (make sure install dir are empty/deleted). 4). Uninstall driver, run DDU. 5). After flashing any ROM from pack above power down PC to fully reintialise card (AtiWinFlash will work with no driver installed). 6). Install driver, OC tools, etc. 7). Another words -> its a Brand New GPU in Your System The V Table for voltage states Editing: Spoiler Some usefull spoilers from OC Forum Greets goes to Gupsterg and others === On moded BIOS Fury (with tMOD + HBM v MOD) This is only TriXX 5.2.1 MOD that is working OK with all drivers up to new one ! -> Here my working TriXX (If you can't OC your GPU in any tool -> try this baby, Moded & HEX edited by me :nerd: ) https://mega.nz/#!Ac82AB7T!zsxYESeVStmCSvjFCoVJO8epkAeBbsWkk3baV7yTonc -- Spoiler My HEX editind history etc. I started when i have AMIGA years ago for Moding SAVES for Games. Usefull with Eye of The Beholder series etc. Also the Game disk in RAM was originally my Idea in that Times ! (I have AMIGA with 2MB RAM 1MB Chip/1MB Fast so i manage to write into RAM disk the 2x Game Disk for Less Swaping and Faster Load Times) Now im using pCache for that in PC -> Games have 1.5-2GB in RAM when first Load. BF:4 or BF:H loads Map in MP in just seconds (3-4sec.) Also i know "things" :nerd: first was Pong in 1974 -> I play it on B/W TV in my House, that was gift from my Father :banana: ATARI 800XL C64 then 128 and with Disk 1/4 AMIGA AMIGA 2000 AMIGA 3000 AMIGA 4000 -> That was a dream machine for me i was on her till PC 486DX with 16MB RAM + GPU and Gravis Ultra Sound ! Then was AMD K2 etc. and 1 Intel P90, in time i had also VooDooo 32MB (Played Quake 2 on it :rpg and so on till today Here my BIOS.es with HBM 1.325v (NITRO OC+/Fury-X/Nano) https://mega.nz/#F!QAkghRJT!W4n7fr-1CPaw7-QzTi04Xg Fury_Tmod_all - Unlocked All CU's + Timing MOD HBM to 400MHz + V Mod HBM 1.319v + Edited for low tW (good for long run gaming 6-8h) [non-UEFI] OC_all.HBM - Unlocked All CU's + V Mod HBM 1.319v [non-UEFI] NewED_all_New.V - Normal Nitro OC BIOS with PL MOD and Unlocked CU's [UEFI] ================================================================================= OC++ BIOS for Nitro: PL 300/280/280 tMOD 400MHz HBM 1.325v & Core 1.218v -> https://mega.nz/#!dcEmWS4K!S457GxGsL5IFaeY0JNCRfeCV5azTAavTq8Ax9CFjsiA My BIOS for Nitro OC+ : PL 250/220/200 tMOD 400MHz HBM 1.325v & Core 1.212v -> https://mega.nz/#!xMdUkASQ!bZzw_r6-MAScs_l2Xpje67t27AW9vZd96CUSOKTyOWY ============================================================== ============================================================== NEW ! Polaris Bios Editing RX480/470/460 Polaris Bios Editor 1.3 For more Info head here -> http://www.overclock.net/t/1604567/polaris-bios-editing-rx480-rx470-rx460/0_50 --- Important Note (THX goes to Only Intruder) On Sapphire Fury Nitro -> Try Flash into first slot if you have Intel UEFI Platform, Blue Slot if AMD UEFI Platform :nerd: "Any stock ROM even with a UEFI/GOP module within it, is technically non-UEFI once modified. There is a bios signature within Legacy ROM section, which is a hash of the hashes of protected tables within ROM. As the mods we do are within the protected tables and we can't update the signature in Legacy ROM to reflect the changes it will fail UEFI checks, thus you need CSM support enabled in motherboard bios to use a modded ROM. The only solution to allow custom UEFI ROM with CSM = Off, is to use a custom UEFI/GOP module in ROM. This solution was provided by Lordkag of Fernando's Win-RAID Forum." But if you don't use secure boot, you can Flash on any position.
