An EVGA tech has said, on this forum, only the 1080 FTWs had a 3-4% faulty VRM rate.
Several people have posted the phrase quoted above, but I don't think it is an accurate interpretation of what EVGA stated.

.... This previous black screen issue was caused by On Semiconductor (VRM IC Manufacturer) VRM IC’s being out of spec, triggering the OCP (Over Current Protection) and will not cause any damage to your system. The percentage of the IC’s that were out of spec has been confirmed by On Semiconductor and is approximately 3% to 4%. ...
Note that the 3-4% estimate is NOT for the "percentage of cards", but rather for the "percentage of IC's" affected. I believe there are 12 of those IC's on each card?
If it is 3-4% of ICs, and there are 12 of them on each 1080FTW, then (for cards shipped before the supply fix on Sept-1)... There is a 36-48% chance of having at least (1) out-of-spec VRM (although we don't know whether (1) bad VRM is enough to cause the problem). Again, this applies only to 1080FTW's shipped from EVGA before Sept-1, and the symptom is "black screen and fans go to 100%".
Bottom line, I don't think we know what the "percentage of affected cards" is. Based on 3-4% of ICs being bad, the minimum would be 3% (assuming all 3% rate and all 12 have to be "bad" to cause failure) and maximum would be 48% (assuming 4% and only one bad IC can cause the failure).
How does everyone else interpret that?
