In the process of step up on a FTW to FTW+ so in the meantime i got another FTW+ for sli. While the stepup is still pending I have both so i figured i would try sli. No go. Tried everything and the option is greyed out in nvidia ctrl pnl. In a last ditch effort i called evga.   I got the surprise! Tech had to speak to manager & they confirmed FTW & FTW+ WILL NOT SLI. Posted this as a WARNING. Who would have thought?????!!! 
 
 
  

The only things i can think of is either the power limit on the ftw and or the pcb as the ftw+ is LARGE! nice copper heatpipes also.. oh and the GPU is closer to the end of the card...some photos of both of them in my bench...

That's weird...they're both technically 970s so I wonder what it is about them that isn't allowing SLI.

The light on the evga bridge works with the ftw+? Current bridge or one evga is working on? TY Jacob

The new 970 SSC and FTW+ use a different type of SLI that allows it to be compatible with things like lights on SLI bridges, etc. Unfortunately this means that it is not compatible with the previous versions however. If you run into this scenario please contact us and we will find a solution.

Thank you Chris! Not just for this, but for all your help. Wish for the life of me i could pronounce your last name!

The current EVGA SLI PRO bridge will light up with the FTW+ and the new 970 SSC.

Is it safe to assume that the new 3975 SSC will SLI with the 3978 FTW+ without problems?

I noticed that also but the old pcb is 9 1/2" & new one is about 10 1/4" almost reachs my sata ports on an eatx mb.... the second one coming may come close to hitting them.43c idle temp w/o fans running. ASIC= 72.0%  stock boost was 1410 solid. not much oc yet. just bumped it up 40 mhz on clock and mem with slight voltage increase and did not change the power target to see if the card was stable... held fine at 1450. For some reason the specs are wrong...see photos..this card is a beast.

When u have it on the bench can yout tell us something on Temps/Bios/ASIC and OC?
 
EDIT: How long it the FTW+? Technical details on the Shop says same size... -.-
 

I can confirm that the GTX 970 FTW is 9.5" in length and this is updated on the product information. I apologize for any confusion.

Thats nice to "hear". Now the only thing is the OC potencial.

So what IS the solution??? I'm having this issue (I have a 970 FTW and a 970 FTW+ in my machine). I guess I made a mistake by assuming that two 970s from the same manufacturer with identical clock speeds would be capable of SLI together. Is my only option to step up my FTW to an FTW+ and spend another $100 (I got the FTW on a good sale)?

OK let me see if I understand this correctly. Are you saying that your FTW and FTW+ do not SLI together? If so contact EVGA tech support.

That Is what this entire thread is about, lol. From beginning to end, the ftw and ftw+ do not SLI. Started in post 1 and he is having the same issue.

Step up may be the next step. The ftw+ is a better revision with multiple changes over the original ftw.

Yeah, unfortunately every single step up option says it's on backorder at the moment...
 
I'm hoping Microcenter will let me exchange the FTW for a SSC (04G-P4-3975-KR). I'll have to pay them an extra $17 plus tax, but I'll get a compatible card to pair with the FTW+. I just wish they carried the FTW+ there.

The ftw+ is in stock through EVGA. Maybe return the ftw if you aren't outside of to your window and order the ftw+?

That could be an option. I'm just hoping Microcenter doesn't try to stick me with a restocking fee...

Please contact EVGA support. They will assist you. 

I did that. They directed me to the FAQ (59534)

so wait a minute you change a essential version of a hardware to put freaking lights on it? no wonder im having issues with my SC and my new SSC 970s on sli.. Say sli cable not detected

Far more than a light. Vrm changes and everything.
