it's literally a reflash of the bios to make the old, 10000 gbps chips run at 11, it's kinda worrying because these modules actually saturate at certain speeds and DO NOT offer better performance or scores because of the noise created in the throughput............ That's why specific 11g modules exist, they were designed to counter this behavior at higher frequencies. 

Exactly the reason I'm asking. However, it's not out of the realm of possibility that the FTW2 cards got these new RAM chips. These cards were produced around the same time the new GDDR5X chips would have been available. Maybe eVGA wanted to go ahead and outfit these iCX cards with better memory, but couldn't announce it until nVidia made the official announcement. Now that it's out in the open, they conveniently release a BIOS update that unlocks that hidden potential.
 
Either way, I'll be flashing and testing this all weekend. =)

here is the proof look at the model # of the mem on these PCBs the 1080 FTW and 1080 FTW2 both have same model # the 1080ti has totally different # 
GTX 1080 FTW




GTX 1080 FTW2 

 
GTX 1080ti

Sadly no, these are the old chips the 2nd revision is a totally different model.
 
I'd say this to anyone potentially looking at flashing, benchmark several runs and average them out at different memory oc's. if you start seeing a certain decline in performance at a certain point, you'll know whether or not it's worth your time.
 
I've seen FTW2's that actually lose performance at as little as +200 total mem, others that are good up to 800 or so....  Mine loses performance at 400, Curious if this bios revision changes anything else to help potential...

it is stupid to flash your native 10gbps 1.35v vram chip on your old 1080 to new 11gbps bios.
because the new 1080 comes with native 11gbps  1.35v vram chip...
 
unless the ftw2 and sc2 are using native 11gbps 1.35v vram chip, which is disgusting to all ftw1 sc1 buyers

I'm glad you can read that. I can only make out number on the FTW. The FTW2 and 1080Ti are too blurry or faded to read.

Oh evga...
 
 

Well the fact that there will be some cards that won't be stable at this new memory speeds probably means no, EVGA should have have released a new version with the new memory to avoid these issues.  I was able to overclock my GTX 1080 FTW ACX memory to 11gbs but I did not dare to test it in games for obvious reasons.  I got one last July so it may die early do to a faulty VRMs, I did do the bios and thermal pads fix though.  Perhaps I should pay for an ICX upgrade for the extra cooling and this new 11gbs memory, plus the option to step up to a Ti?

And GTX 1080 FE ?

Here's another thought.
 
Since they only made this BIOS update available to the iCX cards, they must have different memory chips. Otherwise they would release a similar BIOS update for all the other 1080s in the line. Why are the iCX cards the only ones to get the bump in speed if all the other 1080s have the same RAM chips?

indeed almost all old 1080s with native 1.35v 10gbps gddr5x micron vram chip can overclock to 11gpbs.
but the new 1080 now comes with 11gbps 1.35v native vram chip, which means (and shown by guru3d latest review) these new 1080 vram can further oc to 12gpbs which your old 1080 can never be achieved to such high level.
