24GB RAM: 3x8GB or 1x16GB+1x8GB?

Hello, all digichasers.com visitors. I hope this article will be helpful to some. Recently, I was approached by a friend who asked, is 24gb of ram good? Because on his motherboard are four slots, and he already has two sticks installed. And now they buy a third stick are not sure about it. I will try to explain whether it is good or bad, and only you will decide.

The simple answer

dual channel 4 slots

If you have 4 slots for RAM: you will need to use sticks in this way 0 + 8 + 0 + 0, then this might run in dual channel mode, but most likely, only 8GB of the 16GB stick will work in dual channel mode.

dual channel 2 slots

If you have 2 slots for RAM: Motherboards with two slots, each of them is a single channel. So if you install a matched set, dual-channel mode, it will be turned on. So if you install 16 + 8, they will probably not work in the Dual channel, and if they luckily do, 8GB of 16GB will be used in the Dual channel.

You can run it in “Flex Mode” which will run an 8 GB stick and 8 GB in the 16 GB stick as dual channels and the other 8 GB using a single channel. Make sure that your motherboard supports it.

Best solution

The best solution is to have 32GB of RAMs is to have 0 + 16 + 0 + 16, and the best performance would be if the RAM stick had one manufacturer and the same parameter. Usually, the more slots you use, the lower frequency/higher-latency memory you end up having to pick. 

RAM in the second-hand market is really in demand, so placing an 8 GB RAM stick at a reasonable price will make it easy to sell.

The importance of dual-channel while gaming

In the majority of games, dual channel does not have a significant impact on FPS. Most rendering is performed on the GPU.

It depends on what game you are playing. Certain games are highly dependent on memory bandwidth. However, a dual-channel is always better than a single-channel in different amounts based on what game you are playing.

Below is an excellent example that dual-channel memory is always better than single-channel.

Why can’t you have 12GB+12GB of RAM?


RAM sticks always come in 1GB, 2GB, 4GB, 8GB, 16GB, 32GB, get the idea? There are no 3GB, or 5GB RAM sticks in the market for some reason. So if you have or want to have 24GB of RAM, that means you will need 8GB + 8GB + 8GB or 16GB + 8GB, although none of the examples provided are good.

The reason that it’s not suggested mixing sizes of different sizes is because it is difficult to predict what impact it has on the chip’s timings, and even changing the modules could affect the stability.

Best 32 GB RAM

If you want the RAM to run in a Dual channel, the ram stick must be at least 2. We would suggest buying this RAM. Because they are a reliable manufacturer and have 3600MHz speed.

TEAMGROUP T-Force Delta RGB DDR4 32GB (2x16GB)

Pros: Speed, DELTA RGB, Aluminum alloy heat spreader and Supports XMP2.0 one-click overclocking technology.

Cons: CL18, (CL is the term “cas latency”. It indicates how many clock cycles it takes an item of data to become available once the memory controller has requested it from RAM) and lower is better.

Of course, you can always buy second-hand RAM sticks, as the frame usually has a long service life and rarely breaks down because it has no moving mechanical parts.

It is essential to know that the fewer slots you use, the faster the RAM will run, so to have more RAM and run in a dual channel, we would buy 16GB + 16GB.
