I wanted to thank EVGA for providing these firmware updates. It seems a lot of EVGA users have upgraded.

 
Nice little improvement.

Ok so I flashed my 1080 FTW with the 1080 FTW2 bios. In order to keep the comparison apples to apples, I matched clock for clock for both GPU core and Memory. Here are my results:
 

 
It would seem that it's within margin of error but here's where the plot thickens, the new bios would pass all stability tests but when I tried to match it clock for clock with a +500 offset on the memory with the old bios I would fail almost every stress test with the exception of Superposition. I heard mention of a change in timings and that might be true but there is also a chance that the memory voltage is slightly higher.
 
An important note: Obviously, this didn't brick my card but I flashed this onto a 1080 FTW that is in a custom loop. There is no telling how this bios will impact an ACX cooler since it was designed for an iCX cooler with independent fan control. In other words, just because this worked for me, it may not work for you because the main distinction between an ACX and an iCX card is moot for me in this use case because I am not using the cooler or the fans.

 
 
 
 
Thank you for testing this, can confirm working here as well! :) This is on a 6286 FTW. My card ran +600 on memory previously without a hiccup. I am still able to pump another +100 into it with no issue. :)

Good shot evga....

Nice that evga is doing this

if firmware tuning can be used so easily I don't know why aib partners aren't using it from the get go with their own models, over nvidia's standards!

3 x runs using Superposition Benchmark
 

 
I then realised that I wasn't on the latest driver lol.
 
I'm using 2 x GTX1080's
I also used the SLI mod that allows Superposition to use both GPUs.
 
Nice little increase. No artifacting, no overclocking. I guess the next step would be to update the drivers, attempt a little overclock to see how far I can push the cards with the new 11GHz Memory.
 
Thanks EVGA!

So if my MEM Clock Offset is + 400MHz should I reset it back to 0 and then apply the bios update?
Also, can I apply the same offset after the update?
 
Thanks,

yes set to 0 and no you cant your memory will be running at 11ghz after the flash, you would need to retest and see what headroom you have left if any.

The FTW2 BIOS 40.81 only partially works.
At lower core clocks the memory goes to 5504mhz (11ghz) but at maximum 2025mhz it's still at the old 5005mhz (10ghz) memory speed. It would be a lot easier if these cards just had 2D and 3D clocks like AMD cards. Afterburner is almost useless.
