I am using Kingston KVR1333D3N9/4G-SP DDR3 RAM of 1333 MHz. Recently, I have found that this RAM is of much higher price to buy, instead I have found that KVR1333D3N9/4G DDR3 RAM of 1333 MHz by the same company is relatively much cheaper. What is the main difference between these two (apart from model names, where one is with SP extension and one is without it)? Should I have to buy the exact same model (another SP one to fit with my given SP), or can I buy the non - SP to fit it with the SP one?

The differences are due to use of another memory chip manufacturer on the "SP" version. Otherwise the modules are identical.

Using any combination of two modules (SP and SP, or SP and non-SP, or non-SP and non-SP), the two modules might or might not work together depending on the characteristics of the modules (apart from frequency, voltage, and timings).

Ideally two modules from the same dual channel kit should be used, because the two modules have been tested and are guaranteed to be compatible with each other. When using separate individual modules, as is proposed here, the two individual modules might or might not be compatible with each other. It is a gamble as to whether the two modules will be compatible.

You could try several...

You could try several individual modules (SP and/or non-SP versions) until a compatible combination is found. But be prepared to spend time and money trying different memory modules until a compatible combination is found.

Do it yourself compatibility testing with memory that has never been tested together is not a very good idea. Such combinations carry no guarantee to work together.

I suggest buying a single kit with two modules that have already been tested together and are guaranteed.
