We’re going to talk about which ram slots to use what kinds of RAM are out there, how big they are, and what standards they use, like DDR3 and DDR4. We’ll also talk about DDR5, which is coming out soon. People should know right away what Ram is and how to use it when they hear it.
For this, we’re going to talk about the most basic things, like what RAM is and why it’s important. After talking about its types, we’ll tell you how to choose the one that’s right for you.
What is RAM and what is it for?
There are two things that make RAM different from other types of memory: Random Access Memory, which is the name of the main memory of a device, and the amount of space it takes up. Too much speed on one hand, and too little data on the other, only lasts for a short time. This means that when you restart or shut down your computer, the data it has stored can be lost.
Your computer or smartphone doesn’t use only the hard drive to do everything. If it did, it would take a long time to do them. Because of this, a much faster type of memory is used for these more urgent tasks, and it is in charge of always keeping the data needed by CPU instructions or apps in its memory. They stay there until the computer shuts down or is replaced with another one.
RAM can be used in a lot of different ways through apps. A lot of the data from the websites you go to is usually stored in RAM, which means that when you go back to them, they are already there and don’t need to be reloaded. Don’t fall down. They use so much RAM because of this.
When you open applications, they are stored in RAM, which means you can use them quickly without having to keep typing on your hard drive. So, the more RAM you have, the more applications you can run at the same time, which affects how well your device can multi-task, or how well it can do many things at once.
So, how much RAM you have directly affects how well your device works. To make sure your computer doesn’t slow down, you need to have a lot of applications. If not enough, the computer might not be able to run as quickly as it should.
When you talk about RAM as a physical thing, what you call RAM cards are cards that are directly connected to your computer’s motherboard. This means that these cards have built-in memory modules that connect to each other, and devices like computers have slots for a lot of these cards to be put in.
DIMM memory and SODIMM memory
RAM DIMMs and SODIMMs are two types of RAM memories that are based on how big they are. First, there are dual inline memory modules, which you can find on most desktop computers. Then, there are dual inline memory modules that you will find in most laptops, as well
There are two holes on each side of the DIMM connector’s memory. SIMs haven’t been around since 1996, and these are the new ones. This is the RAM we’re used to seeing, and the size of it depends on the DDR generation to which they belong.
It’s then that we come to SODIMM memory, which we often see in laptops, small laptops, and printers. It is smaller than DIMM memory, with smaller and slightly bigger modules. This makes it good for devices that are very small in size, like phones and tablets.
A third difference is how many contact pins, which are the small slots that connect to your motherboard, are available. This is because size has a direct effect on another difference. DIMM RAMs have a lot more to do with the 240-pin DDR3 module and the 288-pin DDR4 module. DDR3 SODIMM has 204 pins, while DDR4 has 260.
The difference between DDR3, DDR4 and DDR5
There are two types of Ram. Memories of the DDR (Double Data Rate) type Unlike the SDR (Single Data Rate) type, it is capable of performing two operations per clock cycle, performing only read or write operations. To make this possible, DDR chips are activated twice in each cycle of the clock signal, either surface (high or low) or edge (rising or falling).
This way of working is the same in both DDR3 and DDR4 standards as well as in DDR5 which will soon start appearing or its predecessors. However, the more advanced the standard you are using, the faster it will work. This means that DDR4 has a data rate of 3.2 GB / s and a maximum transfer rate of 25.6 GB / s compared to DDR5 with 6.4 GB / s and 51.2 GB / s, respectively.
Here’s a summary of the three main speed speeds, two currently most used and future DDR5:
DDR3: data rate up to 2133MB / s, and maximum transfer rate 17GB / s.
DDR4: data rate up to 3.2 GB / s, and maximum transfer rate 25.6 GB / s.
DDR5: Data rate up to 6.4 GB / s, and maximum transfer rate 51.2 GB / s.
Therefore, newer generations of RAM offer us higher performance than previous generations, as well as higher scalability and energy efficiency. So, if you want high performance, it can be interesting to update it. However, there is a problem, and that is that the amount of RAM you can use is defined by your device’s motherboard.
For example, if you have an older computer that once came with DDR3 RAM, it is very likely that the RAM slots you have are dedicated to this standard. Each has a different connector, so if you want to be able to use more advanced RAM, you’ll need another motherboard.
How to find the one you need.
To find out what RAM you need in your computer, you first need to identify its size and shape, and then you need to know what its quality is. The easiest thing to do is to open your computer and see what kind of memory you are currently using. Identifying whether it is DIMM or SODIMM is quite easy, because you only have to look at the size.
To tell the difference, you need to look at its contacts or pins, the tiny gold “teeth” that attach to your motherboard. DDR4 memories use 288 contacts, while DDR3 contains only 240. This means that if you have one in front of the other, DDR4 will probably be the most interactive.
You can also distinguish them by the position of their mark, the space that is always between two rows of contacts. The mark for DDR3 memories is slightly to one side, while for DDR4 the mark is slightly higher, but at least to the opposite side.
And last but not least, the headline made you dare say that the DDR4 ones are usually one millimeter higher than the DDR3. Of course, the widths are generally the same, although all of these measurements may vary depending on the model.
