What about a motherboard limits how much ram you can put on it?

In: 4

How many and what type of RAM slots it has. In my experience 4 DDR3 slots was typical 5-10 years ago or so but I’d assume DDR4 is more common now.

The most simple answer is the number and type of ram slots available. If you have 4 slots that can each take up to 16 gigs of ram, then you can have 64 gigs of ram.

That obviously begs the question of why you don’t just make a bunch of slots that can each hold a big chunk of ram. And that is where things get more complicated.

Essentially, a motherboard has to be able to provide a rapid flow of data to and from all components. So if a certain motherboard can only possibforever bring 64 gigs of info into the processor Edward scomb it would be foolish to make it capable of having more ram than that.

Honestly, it’s more about the CPU. Modern CPUs have the memory controller chip built into the CPU itself. This will dictate the number of channels (how many RAM sticks it can communicate with simultaneously) and how much RAM it supports. “Low” end CPUs likely max out at 64 or 128 GB of RAM, for example.

Motherboards are built to certain families of CPU, and will be designed to those limits and capabilities. Generally the RAM is just connected directly to the CPU with only minor circuitry on the motherboard getting involved.

And of course, some motherboards really cheap out and only give 1 stick of RAM per memory channel. 2 sticks is possible and rather common per memory channel. On most consumer CPUs 2 channels is most common, so you’ll generally see either 2 or 4 RAM slots available.

The number of RAM slots, the maximum amount of RAM per slot, the type of RAM supported, and the overall memory architecture of the motherboard can all contribute to limitations on the amount of RAM that can be installed on a motherboard. These factors can impact the maximum amount of RAM that can be installed, as well as the overall performance of the system. So, yeah, there’s a lot that goes into it.
