Que tengas dos bancos de memoria ocupados, no quiere decir que trabajes
en doble canal, si la placa tiene 4 bancos.
Fijarse en el manual.
Normalmente, suele decir algo como "Usar bancos DIMM_A1 y DIMM_B1", y
luego, "DIMM_A2 y DIMM_B2"

Esto estaría indicando que estás usando doble canal, pero, repito, leer
el manual, porque no todas las placas madres son iguales.
Hay placas que los bancos son de distinto color, uno negro y el otro
azul. Se ponen las memorias en los del mismo color.
Lo mejor, abrir el chasis y fijarse.
Saludos.
