Help to install CPU-X to see the information system of my laptop

[Carlos Bernardino]

Hello again,

Thanks for your attention.

I need to know the latency and the CL of the RAM. I know it's DDR3, but I don't know the details of the RAM exactly, because the manual about this laptop doesn't mention those details and CPU-X doesn't mean the latency and CL in none part, and in Windows, I remembered that appears that information but I don't remember now!
I think, about SATA, that this laptop has the SATA 1 or SATA 2? If I buy a 2.5 SSD with the SATA 3 standard, I think I can install it in the SATA 2 or SATA 1 standards, if I'm not mistaken. I want to upgrade the RAM, for this laptop starts more quickly!
The model of the laptop is ASUS x550CA XX103H !
Please, can you help me answer my questions?

Thanks again!

Regards.
