i think the rock64 page on the pine64 website has some documentation that includes a technical reference and a rk3328_box_ref_v10_20170224.pdf which on page 4 shows that vcc_io that goes to tf [sd] card is 3.3v and emmc is 1.8v. as zalius said the sd card is locked at 3.3v and can not switch to SDR104. anyway, if you want to know about the rock64 spend some time reading the documents. i have not looked at the 3399 but it could be that it has both 3.3v & 1.8v in ,(or maybe just 1.8V)and therfore can do the SDR104.
