Optional BIOS updates are now available for the EVGA GeForce GTX 1080 FTW2 and SC2 that enables 11GHz memory speed, this update is OPTIONAL and gives improved performance in 3D applications. NOTE: A small number of cards may not be stable at this new performance mode, please see below for installation instructions.
 
For FTW2 cards, you can flash the primary or secondary BIOS. To flash the secondary BIOS the BIOS switch on the card MUST be set to the secondary position before applying update. Flashing to one BIOS is recommended in case you need to switch back for any reason.
 
Windows (64bit) Installation

• Download the correct .zip file below for your graphics card below. ENSURE THE PART NUMBER MATCHES.
• Extract the files to a location on disk.
• Make sure no programs are running in the background, and double click update.exe.
• Press "Y" to begin the update.
• DO NOT TURN OFF POWER OR RESET DURING THE UPDATE PROCESS!
• After update, restart PC.

 
 
 
Testing
After applying the BIOS it is recommended to test for stability, a small number of cards may not be compatible with this update. Use a 3D application or game and watch for any visual abnormalities or game crashes, if this occurs please contact our support at 888-880-3842 or support@evga.com so we can assist you. As a reminder this BIOS update is OPTIONAL.

If for whatever reason you need to flash back to the original BIOS, please use the below links to revert back to original (10GHz) performance mode:

Thanks Jacob. I guess that answers the question if EVGA will be selling the 11gbps version. A bios update is much cheaper lol.

Most important part of the entire post as well... too many people will be posting issues without read this. Everypne SHOULD save the original bios through GPU-Z before updating.

Forum post will be updated with original BIOS shortly if you need to flash back for any reason.
 
EDIT: Original BIOS's are now in top post. If need to flash back for any reason use the above links.

Again, thank you. That would be awesome just in case.

The download descriptions are not correct, Jacob
6686 is 1080 FTW2
6684 is 1080 FTW2 DT
6583 is 1080 SC2
6581 is 1080 icX

It's corrected, thanks

I will be testing this out this morning,  I'll chart averaged runs over a few top benchmarks and games to see what this does performance wise.  I'll try to post these results later this evening if I can.
 
 

So this begs the question. Do the current 1080 FTW2 iCX cards already have the improved 11Gbps GDDR5X chips? Or is this BIOS update just pushing the old 10 Gbps GDDR5X chips to their limits?
 
In other words, do my 1080 FTW2 iCX RAM chips have even more headroom? Or are we taking 10Gbps RAM and just overclocking it to it's max with the BIOS update?

I bet its just like you say and they are just OCing the 10Gbps GDDR5X cause the new GDDR5X on 1080ti and titan Xp is 2nd Gen 

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.
