Thx to Asus I was able to test the newest Fiji card based on custom PCB and I have to admit it impressed me a lot. Photo gallery: STRIX FURY X MOD Thx to tx12 OCN wizzard we can push Fury cards even higher! LINK TO THE ORIGINAL THREAD/TOOLS I will later upload modified LN2 bioses for Asus R9 Fury Strix card Stock (3584 Shaders/224 TMU) 3776 Shaders/236 TMU 3840 Shaders/240 TMU Fury "X" 4096 Shaders/256 TMU Fury "X" 4096 Shaders/256 TMU OC on air - still has some potencial despite unlocking units - TESS OFF VOLTAGE MODS Note that all you are doing on your own responsibility and volt mods void your warranty, same as flashing unlocked bioses and so on 1. Enable HOTWIRE soldering points, do it as in my picture, don't connect HOTWIRE LN2 pads! cause it will trigger 0.95v rail OVP in drivers 2. 0.95v Rail mod (after the mod stock will be around 1.06v) 3. Trimpot/hotwire VGPU, VMEM, VPLL (VDDCI) mods My card after modding: GPU POT MOUNTING Note that Fury has different mounting holes - they are even bigger than old huge G80 mounting. I used modified G80 mounting from Kingpin TEK9 6.66 Fat Pot and it worked perfectly. SOFTWARE GPUTWEAK 2 TIPS: 1. After flashing LN2 bios you gain VGPU regulation up to 2.0v 2. Don't forget to use "Overclocking range enhancement" if you want to have memory frequency control. LN2 TIPS: 1. Use HDMI port (I used it with HDMI - DVI adapter), on my card screen is blinking on DVI after 0.95v rail mod. HDMI port is fine even at -180*C. 2. If you can't enter OS at certain temperature - lower 0,95v rail (E.G. from 1,25v to 1,2v). 3. 0.95v rail set to 1,25v should be enough for -120 -160*C range. 4. With lower temperature (-50*C and more) you have to use higher VGPU to boot into OS! I had to use around 1.35-1.5v (stress) to boot into OS, it will be around 1.1-1.15v idle (stock is 0.9v in idle). 5. You can set by trimpot/hotwire VGPU OS "boot" voltage and later raise it by GPUTWEAK - it works. 6. 1000 MHz HBM (500 MHz is stock) is current maximum frequency which we can set. For that I had to use 1.55v VMEM (stock is 1.35v). Note that on some cards score might be lower with too high memories. 7. My card doesn't have CB or CBB. 8. PWM is strong, 1.6+ VGPU wasn't a problem with a delta fan on it. 9. Use stock PLL (AUX - VDDCI). Higher gave me nothing (stock is around 1.0v), 1.2+ can kill your GPU. BIOSES AND SOFTWARE Stock Fury and Fury X bios have COLD SLOW bug below 0*C (3D mode doesn't work), you need a special BIOS with a fix. For now I used Fury X (ref) LN2 fixed BIOS but it works on Fury Strix cards. UPDATE: Note that LN2 Fixed bioses have disabled monitoring of temperature, you can flash it and try on air and it won't kill you card, but you will be playing "blind".

From what I know some cards should easy do around 1600 MHz. Most likely limit will be similar to R9 290X cards . Locked stock shaders: Fully Unlock Card is a great fun. Very easy, issues free. Everything works, software (GPUTWEAK 2), drivers and so on. Thx Asus for that great card! I hope we will see a lot of results on it All of this wouldn't be possible without Asus R&D support (Jon, TL) and tx12
