Ahoj,

Asus Z10PE-D8 WS s dvěma CPU a 8x16 GB RAM ukazuje následující dvě zprávy:

Sloty na desce jsou fyzicky popsané DIMM_A1 až H1 a adresa, ve které došlo k chybě, spadá do DIMM_F1. Jenže mi není jasné, jak funguje ten dual channel - naivně jsem si myslel, že paměť interleavuje po malých blocích (šířka sběrnice nebo cacheline), jenže v tom dmidecode je vidět, že paměťové moduly jdou po 16 GiB. Není možné, že je chyba třeba i v modulu DIMM_E1?
