I have no idea either. Maybe S1 and S2 refer to a primary and secondary socket but you would need make/model to confirm. One memory socket can be easy to get to and the other one hard.

We ordered extra memory module for laptops , &nbsp;they have same speed as existing one but are S2, <br />

I have no idea what is the difference between Memory module s1 and memory module s2 ?<br />
Can I use both together in the laptop or it will cause problem?<br />
