There have been confirmed reports of CTD with XC3 Ultra, I had an order for this card on Amazon but I just canceled it this morning. At this point, there's so much going wrong with this launch that has turned me off on adopting early. I decided to wait to see what the 3070 and Big Navi have to offer and let the partners figure it out and fix their issues before buying. Hoping that I can get an upgrade before Cyberpunk 2077, but if not, at least I'll appreciate the upgrade more when I do!

Where did you found this information ?
The lonely one I found about the crash explained later that it was a false alarm as the problem was not from the Graphic Card itself 

So every 3080 EVGA offering is safe? XC3 and FTW3, both regular and ultra?

 Its too soon to say its safe.
 
 Hardware unboxed said :  The crashing with the RTX 3080 cards doesn’t appear to be down to the caps used, which is why we haven’t made a video yet, we don’t know the issue. What we do know is the FE and TUF Gaming models crash just as much as other models and they use MLCC’s.

Is there a screenshot of the crash? Any error codes for it?

There is so much mis information in this thread.

First please watch this actual hardcore overclocking video that explains a ton more about this potential issue.

Here are some other points:
1) POSCAP is a specific model of capacitor made by Panasonic so calling all SMD polymers as so is like calling all soda Coke, it’s incorrect.
2) MLCCs are not just universally good as well. Just like all capacitors they have several models that have different spec etc, so you can’t just say small is good and big is bad
3) power delivery is more than 1 component, you need to investigate the entire pcb to actually say if it’s good or not

MLCCs and SMD polymers each have different specs different things they are good at etc, the best you can do is mix and match to fit your board, which is what I believe EVGA has done.

Buildzoid's video is great, however I disagree with his and Jayz comments about part cost and build time - there's a negligible difference, it's a wash.  However, some designer somewhere probably did spec the tantalum caps just for simplicities sake / best practice, with the OK of Nvidia's design guidance.   Zotac even went as far as deleting the ceramic array pads from the PCB.

So basically I need to wait till the 3080 Ti version comes out to see if that design is better? since it's a gamble right now to spend 800 bucks on card that has a good chance of crashing with whatever the mystery problem is that is causing this event.

They? EVGA? How can you know their design/modification process?
 
EVGA builds power supplies, motherboards, video cards, and a handful of other components. If EVGA doesn’t have a shop that can make the kind of measurements it takes to troubleshoot, locate the issue, and test and verify their solution, I would be very surprised. I might even be able to see the issue myself with my own oscilloscope. What we are talking about is probably complex to people who aren’t at least electronics hobbyists but it’s not rocket science either.
 
It doesn’t matter how Igor made his discovery or even if it was a tip from some insider. He still nailed it. The details and the actual best combination for a particular model board is/was up to each manufacturer to determine.
 
EVGA is in production with new cap combinations now. All EVGA retail cards are running with combinations determined by EVGA. It’s a safe bet they are tested. EVGA has even been going through the delay and expense of reworking their 3080 FTW3s. If I was a manager there, I would want to know for certain the delay and expense was necessary. I cannot believe they would just wing that.
 
Also, graphics cards crash if you clock them too high. It’s just how it goes. All boards will fail at some level of overclock. Maybe it’s some level of residual noise in the capacitor section causing the crashes, or maybe it’s some other issue now taking over. Maybe there’s some log file or software diagnostic that can say if the failures are the same (just at some higher clock after the mod) or if the reason cards crash now is likely due to some other cause?

+1  Many people who don't get the OCs they want or passed the advertised speeds will think their GPU is an issue. 

As it stands, there are no issues with the GPUs and each one will OC differently from one another aka silicon lottery.
