CPU Memory to Speed Configuration
The following table provides corresponding information for CPU type to memory speed. CPUs with 6.4 GT/s
support memory up to 1333 MHz, while 5.86 GT/s support up to 1066 MHz and 4.8 GHz only support 800 MHz.
Memory speed is automatically downgraded to match the supported CPU value. As an example, 1333 MHz mem-
ory with an E5530 CPU, rated at 5.86 GT/s, is detected at a speed of 1066 MHz because of the CPU rating. See
the following table for further information.
