I am afraid to say that I can provide the information about the processor configuration only since I am a specialist on Intel ® products.
Based on the memory information from the website, the memory will be running by default at 1333MHz but it does not specify if the memory will down clock the speed. My best recommendation in regards the memory is to confirm with the system manufacturer if it wills down clock automatically or if you need to change a setting at the BIOS level.
In regards the Intel ® processor, it can handle a memory up to 1066MHz. using a faster memory can damage the integrated memory controller inside the processor and can cause the system to crash.
