The model number for my original card was 08G-P4-6286-KR and my RMA card has the same model number. I thought the new cards with the fix had a different model number?

Try overclocking with your memory at default. Set the voltage to 100% so precision will allow the card to use all the voltage it can. Then set the power and tempt to max. Test the overclocks with 3dmark firestrike. That way you don't mess up your game when it locks up. Usually you'll get a driver error message pop up if it freezes and it will recover without worry.

I usually max the fans but at least set them manually as high as you can bear.

Well unfortunately my FTW has done the same thing a couple of times. Fans at full speed and PC has to be restarted. I haven't had any issues since switching the BIOS switch to the 130% Power setting.  I'll wait to see how it goes since I'm in Australia and would have to RMA through Taiwan I think.
Has anybody tested between BIOS's?

Like what was said here earlier many times this is appears to be an issue with defective cooling and thermal expansion so whilst down clocking or debug mode may seem to "fix" the issue it will come up again later with more frequency as thermal expansion catches up.

Your best bet is to return to your retailer for store credit and get another brand OR RMA to EVGA insisting postage and any import duties fully paid.

Once again, down clocking to what appears to be stable is NOT going to work. I had a sample size of two and I'm confident eventually this will happen to you again as it did to both my cards.

This is also definitely not a small percentage all cards are plagued with this issue. Why else are there so many more views than posters? Most people just read and then RMA directly without even posting.

 
As I m running in debug mode to avoid the black screen... I have noticed stuttering appearing after a while during gameply in multiple games (F1 2016, Killing floor 2, COD BOIII), My system was rock solid previously with a 780ti and I never experienced that kind of issue in the past. Could it be linked to the black screen issue? 
 
Would be good to know the root cause of all this, either PCB design flaw, bios, VRM , cooling system ....

RMA Update: 
 
Received my card today.   Stock clocks are much lower than my previous card out of the box. (1936 or so out of the box when running a game)
 
I was able to overclock to 2000 mhz / 5500 (11000) on memory so far.    2025 core crashed quickly in Overwatch, so I downclocked it to 2000.
 
NO Crashes so far, played over 1 hour of Battlefield 1.  I will keep monitoring it as games before would randomly crash, even at stock clocks.

Doesn't sound like a FTW card.

I've got the exact same problem with my card, already made a ticket but can i call their office in germany from the netherlands or is that only for germans? Same question for their UK office

Can anybody from EVGA confirm that the stock of hybrids due in @ scan UK tomorrow are of the new fixed pcb's please as I dont wanna order one to have to RMA (yes, I also understand not ALL cards are affected)

How so?

No, the model number has not changed.
