Z890F slot A1 and A2 not working

[Marcus55]

Hello,

i just got a Z890F Gaming Wifi motherboard

memory slots A1 and A2 do not work.

If I put 2 DDR5 Corsair 6400 C32 2x 16GB in slots B1 and B2, it works, if I put these same DDR5 Corsair 6400 C32 2x 16GB in slots A1 and A2, it does not work

Bios ver 1002

Perfect CPU installation (Intel Ultra 9) no fault

Asus Rog Strix LC cooling !!! 360 ARGB

do you have a solution?

thanks

les slot mémoire A1 et A2 ne fonctionnent pas.

Si je place 2  DDR5 Corsair 6400 C32 2x 16Go  dans les slots B1 et B2 ,ça fonctionne, si je  place ces mêmes  DDR5 Corsair 6400 C32 2x 16Go   dans les slots A1 et A2,ca fonctionne pas

Bios ver 1002

Installation CPU parfaite (Intel Ultra 9) aucun  défaut

If I put 1 DDR5 Corsair 6400 C32  16GB in slots A1, it does not work

If I put 1 DDR5 Corsair 6400 C32  16GB in slots A2 and  1 DDR5 Corsair 6400 C32  16GB in slots B2, it does not work

If you have only one module, you always put it into A2. If you have two modules, you put them into A2 and B2. Only if you have 4 modules do you populate A1 and B1.

That is really odd. And you tried already to clear the CMOS and reset the motherboard to the default values?

thanks for your answers,

yes, already tried, I also checked the socket, no damage, I also checked the pins of the Intel Ultra 9 CPU, they are perfect, no damage
