Can I SLI EVGA GTX 970 FTW & FTW Ref together?

[LittleKat]

Hello everyone! Merry Christmas to you all!

I currently have an EVGA GTX 970 FTW ACX 2.0 - 04G-P4-2978-KR. I wonder if I can SLI it with an EVGA FTW ACX 2.0 Ref - 04G-P4-2977-KR.

The difference between them is the base clock. ~11xx vs ~13xx (sorry, can't remember the exact rates)
