Hello,
AFAIK modern intel memory controllers support so-called Flex Mode when dual channel interleaving partially works even DIMMs have different sizes. This DC mode is called "Asymmetric".
And native dual channel mode is called "Symmetric".
CPU-z always displayed me DC mode on its memory tab, but not now. I have PC with 4 DIMMs installed. All 4 DIMMs are the same. I have dual mode, but CPU-Z does not display me DC mode (this field is disabled, it is gray!). I used Aida and Sandra to check ram performance and it is close to dual mode (~ 20 Gb/s for PC3-12800). But why CPU-Z doesn't display me "symmetric" mode?
Could it be that my CPU (i7-3770) does not report it via SMBIOS (or what ever is used to report DC mode) so Windows (and CPU-Z) does not know it is used?
