I just realised the memory in my UDOO x86 board (N3160 version) is single channel which not matches the specs "Dual Channel" in Kickstarter campaign page and product page. Hence the speed test is a typical single channel memory result. As far as I know, there are no options to control single/dual channel in BIOS or somewhere else so it is unlikely that I set something wrong. I felt so disappointed because I considered it was a feature (so as UDOO) when I decided to support. I suspect there are some changes when in bulk production since I notice in this video, the board on desk has 2 SODIMM. I post this just want to get some explaination from UDOO about making products that don't matching the specs.
