Memory Speed Limitations
The memory frequency is determined by a variety of inputs:
•SpeedoftheDIMMs
•SpeedsupportedbytheCPU
•CongurationoftheDIMMs
The memory speed of each channel depends on the memory configuration:

module speed
If memory modules with dierent speeds are installed, they will operate at the speed of the slowest
installed memory module(s).
