hello I have a Lenovo IdeaPad laptop and 570, and I would like to increase the memory to 8GB (comes with 4GB), but I have some doubts.
1) that can happen if I install a Kingston Value Ram, instead of one made specifically for my laptop?
2) in the data sheet says it uses DDR3 1333MHz, but it is strictly necessary to be 1333, or it can be higher? And if possible, what would happen if the new memory has 1600MHz?
3) what would happen if the memory has the same specifications as the one that comes with the laptop but different brands?
4) and finally, it would be possible to install a memory kit of high performance, such as hyper x brand Kingston?

Any recommendations about memory brands?
laptop specs

There is no reason you cannot upgrade to 8GB RAM

- No necessary benefit to getting higher speed RAM, as the system will only use up to the speeds it is capable of, i.e. higher speed ram will merely regress to the 1333MHz level, if that is the maximum capability of the system.

- High performace RAM is really only beneficial if you have a BIOS that can make the adjustments to fully utilize their features. Most laptop BIOS do not have that access.

- Best to check the baseline specs of the RAM and use that as your determining factor.
