Just got my RMA and just like the others have said, no black screen and more coil whine. I'm happy with this replacement overall. 2.1 Ghz overclock just like my old one. 2025Mhz out of box.
I also noticed that the bios switch was on slave out of the box

Got my RMA card yesterday. And i am very disappointed to say that i still get black screens and 100% fan noise.  The card was sent after 30. aug.
 
I sent a mail to the support person i have been talking to. And i really hope they will resolve this quickly.

Dear zell2004,
 
I am sorry to hear that you are still having a problem.  I am emailing you directly and also will be checking with our EU office to ensure that you can be helped immediately to assist.

I have 130% power limit on both the master and salve bios on my RMA gpu. hopefully no issues with this.
It's all good. just a glitch.

Received my RMA FTW Hybrid card today. I haven't even installed it into my PC. As I was unwrapping all the plastic and port covers I noticed that there is no BIOS switch to toggle between master and slave BIOS! The marking is on the card but there's no switch! I emailed support to request another RMA. This whole process; black screen and fan issue plus this now is so annoying.  Stuff happens beyond EVGA control I get it. Maybe it is a sign that I should stick with my 980 Ti.

That's very poor quality control.

I had this issue as well, troubleshooted, and was able to fully resolve my issue.  I outlined my findings below.
 
General Initial System (Black Screen Fans Loud):
Motherboard: Asus X99A II
CPU: I7-5930k
Memory: Corsair Dominator 16gigs
HDD: Samsung 950 pro
Power Supply: Corsair CS850
GFX Card: EVGA GTX 1080 FTW
 
Working System:
Motherboard: Asus X99A II
CPU: I7-5930k
HDD: Samsung 950 pro
Memory: Corsair Dominator 16gigs
Power Supply: EVGA Supernova 850
GFX Card: Asus GTX 1080 Strix 8 Gb Gaming

Short Answer: This is a Graphics Card issue.  
The card is not handling the voltage current for whatever reason (heat?) which causes the inevitable crash.  I noticed that the Heat was unpredictable with my card.  At first it found its way all the way past 93 degrees Celsius prior to crashing, and gradually it was start to crash at 71 degrees Celsius.  Possibly it cooked itself over time, however, I am not the engineer of the card so will stop this one short.
 
In my experience and understanding, a hard crash will always be the result of hardware not sending the instructions correctly.  For example, if a card gets too hot, the high voltages and low voltages are likely to be affected in some way and therefore your system turns into the "leaf blower".  Software level issues will almost all the time result in a soft crash.  Even malicious software would be difficult or impossible to write that would be able to tell your hardware to basically commit suicide.  In my understanding, a lot of the confusion with regards to drivers causing blue screens and hard crashes is inherited from the Windows 95 days, however, those also were hardware related becomes the Memory Management had memory leaks.  As more and more memory leaked, the drivers that used the memory had to end up taking the blame.

CPU and Memory: I tested the CPU and memory with Prime95 and it had 0 issues over 12 hours with maximum heat reaching about 45 degrees Celsius.  (Excluded)


HDD: Samsung Magician tested and verified in good health.  Issues were isolated to High End Gaming.  If HDD defective the issue would popup at anytime.  (Excluded) 
 
BIOS Settings: I did note that when the XMP or any OC settings is enabled and then disabled, that the timings were not reset properly and the core CPU was actually reduced.  To get it back to the optimal settings after enabling XMP or overclocking involved flashing the BIOS to the latest version.  Issue occurred regardless.  (Excluded)


Power Supply: Replaced and the issue repeated.  (Excluded)
 
GFX Card: After installing the Asus GTX 1080 Strix I have never had the issue again.  I noted that Temps always hold steady at a max of about 68 degrees Celsius no matter the load.  Voltages typically don't move around and go from 250 - 750 - to 1850 or so at full load. (Identified)

To the above.. it's not heat related. I know have 2 hybrids. Cool temps never past 45c. Usually hover around 42-43c on load.

Anyways your card should never went past 83c as that's the max the card will allow before throttling down the voltage and clock to stabilize itself at lower tempts.

Sound like it was a faulty card.

Can't believe this is happening. The quality control is below the average. Ruined the FTW's name.
Still waiting for my RMAed FTW replacement, it's been almost two weeks. Getting more and more worried after reading you guys' feedback.
