I have 2GB RAM which I want to upgrade to 4GB. I have purchased DDR3 1333MHz RAM but according to Intel my laptop Pentium P6200 processors support DDR3 1066. Is there any way that my processor can recognize 1333Mhz RAM?
The memory should automatically run at 1066 Mhz
Memory modules support different speeds and timings, and the figure 1333 just indicates the highest speed available.
If you are using 2 ram modules it is best if they are of identical speeds.
