Theoretical Maximum Memory Bandwidth for Intel® Core™...

Web2 days ago · The memory speeds (clock rates), maximum capacity per memory module, total maximum capacity, and types (DDR, DDR2, DDR3, etc.) that a system can accept is defined by the memory controller. WebFor example, to find the data rate of PC3700 memory use the following equation: 3700 / 8 = 462.5. This is an approximation of the data rate and would commonly be labeled as 466MHz memory. For simplification, some of the numbers get rounded up or down and may not exactly match a data rate listed.
