The placement of DIMMs depends on the MoBo, its manual would show in which slot should DIMM modules be added and the (maximum) size of each stick the MoBo can cope with. Normally OEMs provide a list of tested memory brands and models for their MoBos (QVL) and it is recommended to buy something on the list, rather than improvise.
Both old and new mobos are, iirc, 4 x 32GB, and they just swapped the RAM over. But again iirc, the new mobo they supplied had two colours of ram slots, something like "black, red, black, red". To me that's obvious - both sticks in one colour! So - and I guess it was an apprentice who didn't know what he was doing - just shoved the ram in the first two slots.
Two major blunders from a shop - a brand new mobo won't boot - the FIRST suspect is an out-of-date bios. And then the second blunder - don't check the ram is in the right slots. That's one shop I certainly won't visit again.
(The only reason I asked a shop to fix it was because I didn't have an old chip so couldn't boot the board to upgrade the bios to work with the chip I had ...)
