ULTIMATE ASUS R9 FURY @ (X) STRIX LN2 TIPS

Recommended Posts

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.

STRIX FURY X MOD

 

Thx to tx12 OCN wizzard we can push Fury cards even higher!

I will later upload modified LN2 bioses for Asus R9 Fury Strix card ;)

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

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".

ATIFLASH 2.71

 

1. Use only ATIFLASH in CMD (WINFLASH corrupts UEFI mode)

 

command: atiflash -f -p 0 bios.rom

 

LN2 results

 

Quick test just to check all the mods and behaviour on cold. From what I know some cards should easy do around 1600 MHz. Most likely limit will be similar to R9 290X cards .

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 :)

Thanks for sharing, I can´t remember having seem HBM clocked that high, results are quite impressive

Wow that HBM frequency!!

 

Did you have a perfect core with CUInfo showing two columns of locked CU's at the end?

Nope :)

 

Thanks! Makes voiding warranty all the more lucrative :D

Any takers to do same thing with fury x? :D

 

It seems fury x's little sister is actual 'overclockers dream' ;)

Thx guys :)

 

thx for sharing.

 

did you applied tim on memory or only on die?

 

Well Tek 9 Fat 6.66 covers only like 1/5 of each memory, I applied thermal paste on them, but in fact they are touching the pot only on the edges.

 

Awesome guide!

 

Is the LN2 bios already up for download?

 

Thx Pieter :) I am waiting for Asus aproval if I can upload them. Note that this bios is software voltage unlocked to 2.0v GPU so considering how strict policy is among vendors (MSI - Afterburner Extreme and so on) I have to wait. But the good thing is that on basis of Fury X LN2 ref BIOS it's possible to apply LN2 cold slow fix to other bioses. Now I have a full set of UNLOCKED Shaders BIOSes with LN2 fix and software voltage control to 2.0v. In the worst case if Asus doesn't allow to make it public, OCers will have to just request R&D for it or I will publish stock Fury Strix bios with LN2 fixed but with lock control of voltages by software.

 

Any takers to do same thing with fury x? :D

 

It seems fury x's little sister is actual 'overclockers dream' ;)

 

Well I don't have Fury X card, but will ask, maybe someone nice will help me in getting a card to play with ;)

 

UPDATE

 

 

Good news - LN2 cold slow fixed UNLOCKED BIOSES are ready and work (tested by myself few minutes ago with last drops of LN2, have to refill dewars tomorrow)

A bit lower clocks (fast run, last drops of LN2) but all Shaders and TMU are activated and efficiency is higher. Moreover I didn't notice any signs that it's harder to clock for GPU or that it needs higher vgpu so it's really good news!

Awesome work, you make the card shine. Now show us some more magic on LN2 after refill :D - 10K+ on stock cpu and mem and not full out on card is looking really good
