So ... 2 cards with 2 STM connectors + 1 card with 1 STM.
Shoud I install 2 STM cables ? One STM wired between the 2 cards with 2 STM connectors and another STM cable between the 3 cards ?
Or just 1 STM cable between the 3 cards ?

Since I believethe 2 stm cables is the logical solution, I gonna try like that.
