How can I choose the right RAM hardware to insert into my PC ? (AN515-51-75ZC)

MorenoSilva

My laptop came with an extra slot to put ram.

It can go up to 32 GB (16GB *2).

Currently I have 16GB and I want to put other 16GB.

My specs:

Host: Nitro AN515-51-75ZC V1.22

CPU: Intel i7-7700HQ (8) @ 3.800GHz

GPU: NVIDIA GeForce GTX 1050 Mobile

GPU: Intel Device 591b

Memory: 2670MiB / 15896MiB

I found some DDR4 rams:

- 16GB 2133Mhz

- 16GB 2400Mhz

- 16GB 2666Mhz

What things should I consider when buying (and replacing) the new ram?

How do I know how many Mhz should I get? I know the more Mhz the better but shouldn't be equal to the Mhz of my current RAM so that I don't have bottleneck?

AFAIK, I need to buy a DDR4 (260 pins notebook version) with a clock speed matches the one already installed right?

Hi @MorenoSilva
Either use CPU-Z to determine your RAM specs.
You can also just look onto the DIMM itself, all the details would be printed on the memory module.

Download and install CPU-Z and look at the specs of your RAM module, you have to get one with the exact same specs if you want to have a dual channel.
