Bigger RAM sticks only matter if they help add up the overall total internal RAM in a computer. Get the most you can!
I'm thinking of purchasing a new PC. I'm purchasing a PC with 8 GB of RAM. However, I'm confused as there are 2 GB, 4 GB and 8 GB sticks available. I just want to confirm the below with respect to performance that an 8 GB will be better than a 4 GB will be better than a 2 GB.
In this excerpt from Answercast #99 I look at some possible confusion between USB drive sticks and RAM memory, and how to get enough RAM in a new computer.
So I want to make sure, I want to make absolutely sure that what we're talking about here is the internal RAM in a computer because the term "stick" is often used to refer to external USB memory sticks. Those are different. They have nothing to do with your computer's RAM.
So, forget the USB sticks, forget the sizes, they just simply don't apply.
Now, when you've got a computer that is capable of having different sizes of RAM memory installed, the "size" you choose does not impact performance. So, that statement that you made about an 8 GB RAM stick being better than a 4 GB being better than a 2GB - not true. Not true. You'd never notice a difference.
The reason that there are different capacities is essentially, cost. A motherboard inside the computer usually has room for a certain number of memory cards - memory sticks. Usually it can be either 2 or 4, although there are definitely some motherboards that have more.
Let's say that your computer's motherboard comes with 4 slots for 4 memory sticks. You have several different approaches to how you can configure that RAM: You can put in one 8 GB memory stick and leave the other three slots empty, or you can put in four 2 GB memory sticks.
Either way you've got 8 GB of RAM. There's no performance difference.
The difference is that with a single 8 GB RAM stick, you can add more. In other words, you can add another one, and another one, and another one. You could put 32 GB of RAM in that machine, if in fact the motherboard supported it.
So that's all it really boils down to: the cost of the 8 GB RAM sticks versus the cost of the 2 GB and how much memory you eventually think you're going to need.
My recommendation, again, not for performance reasons but for expansion reasons, is to always put in the highest capacity RAM stick from day one. That way, you can always add more.
My number two suggestion, by the way, is to put in the most RAM you possibly can when you get the machine. It may seem like a heck of a lot of RAM to start with - but trust me, in 3, 4, 5 years when we're running with Windows 11 (and god only knows how much room that's all gonna take) you're really gonna appreciate having all the extra RAM.
So, again, there's really no performance impact into the RAM sticks, the RAM
modules that get placed inside the machine. Choose whichever set really fits
your budget, erring on the side of being too large if possible - and remember
that the RAM sticks that we're dealing with on the inside of your computer are
completely unrelated to memory sticks that we plug into USB ports.
