There are no markings whatsoever on the board indicating which port is which chain. Any ideas? So far this board looks nice, love the power it claims. However, I’m unsure if it will beat the speed I get from my RB800 boards. Too bad they don’t make a 800mhz version.
REQUEST: 5HPnD with 800mhz CPU and 3x3 MIMO!!!
As you see it with the Ethernet port pointing towards you and upper the MMCX connectors, the LEFT MMCX is the chain0 and the RIGHT one is the chain1.
Correct me if I’m wrong mods. 
That’s what I figured, but since there is no definite labeling for them, and knowing Mikrotik it could be opposite, so figured I’d ask first!
I will see that the future silkscreens include chain labeling. But to remember - all routerboard products have chain0 on the left, when looking with ethernet pointed down
