I got my RMA 1080FTW for this black screen 100% issue and looked over both cards closely. Haven't tested new one for the issue yet. The only difference I could find were 4 of the chips on the back of the card. Old one has "65KQH", new one has "66WQK". Comparison pictures here: imgur.com/a/392sd


I picture someone frantically working in the back room at EVGA with a soldering iron.

For my money, the defective components(likely to do with the voltage regulation system) are probably on other cards and EVGA is trying to cover it up, hence Jacob and ChrisB's silence on answering all of our questions as to what is actually going on with these cards. They better hire some more people to work those soldering irons...

Here is a video on ftw and hydro pcb, interesting video.

Got my second replacement (3rd card now). It no longer stays above 2000Mhz. It stays at about 1947ish with temps at around 67-69. My two previous card with the black screen + fan problem usually stayed at 2038. It could be silicon lottery. Who knows.  I doubt the difference between 2038 and 1947 is discernible, but it just feels good to have a GPU that breaks 2Ghz.




I would honestly be fine with those speeds assuming there is no horrible coil whine - I mean 1950Mhz is pretty damn fast sure it's not breaking 2Ghz but I'm not sure I would ever notice the difference.
 
My RMA arrives tomorrow so fingers crossed, I'll report back with my findings.

Thanks for the pics, I'll be checking against my RMA which arrives tomorrow.
 
Those IC's look suspiciously like Regulators or Rectifier packages, which would point towards power delivery.

My RMA card has bad coil whine compared to the last one. The last one has a very low frequency and was quite pleasant.

I thought that too, that they were voltage regulator circuits, but someone pointed out that they are actually capacitors sourced from Panasonic. You can google it and the pictures you get look just like them. I'm actually an electrical engineer and got it wrong. It still is probably an issue with power delivery, that the filter capacitors they used are defective or they saved money by using caps with too little capacitance or rated voltage. Again, the EVGA reps who have commented in this thread will not respond so they probably are trying to avoid admitting the problem goes beyond just a "small number of 1080 FTWs"

MM I could not find any info on the great google concerning '65KQH' capacitor, can you link me the info you found?

This is the data sheet. And the number is just the lot number. So you can't really tell anything about the caps other than they are from a different lot.

Thanks for that - I should hook my my scope to both cards when running to see if the waveform around these components has 'jitter'.
