How do I choose RAM for Intel HD Graphics?

[Mellelmejor]

Hello, I'm planning on building a rig for playing PS2 games and old stuff, so I'm considering using Intel HD Graphics for the emulator, so I want to know how to choose the right RAM to get a great performance of it.
I know that with AMD APUs you should get as most high speed DIMMs as you can (About 2133 MHz and up), but as Intel is very different, I don't know what RAM to get, I know it should be in dual channel, but don't know the speed I need.
I was looking at the Pentium G4400 because it is cheap, last gen and I think that in the CPU side it can get the job done very well, but I don't know if it will handle PS2 games and that stuff.
Also, I want to get a great performance of the integrated "GPU", so tell me what are the differences between the RAM and what else do I need to know about it.

I was also looking at this Motherboards with built in CPU, please, tell me what do us think for the purpose I want them.

Liked the N3150 because don't need PSU, so I can put it in a very small ITX case.

Thanks in advance!.

Consider the Intel G4500 It has the HD 530 Graphics processor, compared to the HD 510 in the G4400. SO a substantial step up. THen you are correct, the best memory you can get would be a substantial boost to the processor. If you can find qualified memory (either motherboard or memory manufacturer can provide lists of qualified memory) You can go as high as 2133Mhz. I doubt you will see much benefit at speeds in excess of that.

Thanks! Now I know why is the difference of price between the G4400 and the G4500.
So basically you are saying that with 2 stick of 2133 MHz DDR4 or more I will be ok?

I only afterwards noticed that you also asked about the N3150 processor on board.

They are more low-end than the G4500/G4400,

Here's an article with a paragraph explaining their positioning. Look for the word "Braswell" in that article.

Yes, I know, but I want the more because of the portability, as I want to pair it with a case like this http://www.minicase.net/product_E-2019.html , I think it will be great to consider if they are no that bad, I really don't care that much about the CPU, but more about the GPU, so thats a fact for me, and the 3150 is like "plug an play", so I can take it to a friend house or something.
I know that it is a low end CPU, and that probably the difference between the G4500 is big, but I just want it to play PS2 games, so I really don't know what to do.
