Question
Why does the memory run at 333MHz if I use four DDR400/512MB memory modules on A8N-SLI?
Answer
To be more compatible and stable with some memory modules, the default clock will be at 333MHz if four DDR400 memory modules are plugged on the A8N-SLI. But you still can set at 400MHz manually in the Bios to gain better performance. Moreover, in order to get best performance and compatibility, please choose those memory modules which are verified by us. You can get the QVL from the link below.
