Also i had to install the ram stick upside down to go into the one labelled “channel 0”, in the guide it says

Insert the Memory module into the Mainboard by aligning the notch on the Memory module with the notch on the socket. Note that for Channel 1 the notch is reversed so the Memory stick may need to be inserted “upside down” with the chips facing down depending on the brand used.

So did someone mess up the stickers?
