Fastest RAM I can fit in an NP8157?

Im thinking about upgrading my laptop already to 32Gb of RAM. Im looking at going with 2 x 16Gb sticks rather than adding to the 16Gb Hynix sticks already there so I can maintain a matching set.

Currently it has 2x8Gb DDR4 2400 sticks in it. Im partial to GSkill RipJaw RAM. Ive used it since it has come out in various other machines and have never had an issue. That being said Im always open to other options.

 

Corsair Vengeance is cheaper and has a trivially lower latency, 16-18-18-39 instead of 16-18-18-43. I never used it, just consider buying myself.

 

G.Skill is good. Samsung and Kingston are both really stable, too.

I don't think there's a glaring difference in performance or stability between brands so much as there is between models/series.

 

Can I throw faster RAM other than DDR4 2400 in there and actually make use of it? If so what can I go up to? Im not so worried about timings yet.

 

3000Mhz is the fastest SODIMM out there so far, you'll pay a fair premium and fully stacking it at that speed could be tricky due to the load on the memory controller. It should not really impact performance.

 

So what your saying is stick with the 2400Mhz with faster timings and call it a day.

 

The integrated memory controller on the 7700HQ supports up to 2400, so going beyond that is a little redundant; the faster timings will be more to your benefit.

 

It can boot higher speeds which is overclocking the IMC technically but the benefits from doing so are pretty small. Getting a larger SSD for instance would make more sense when balancing a system.

 

Doing so (adding faster RAM) has been a bit hit or miss in our experience as far as stability went.

 

It's going to vary chip to chip and what speed you try to hit, it is overclocking and intel will only validate up to what the spec.
