Random access memory (RAM), or system memory, is a well-known term among users. In layman’s terms, RAM is the shortterm data storage of a system; it stores information that the computer is actively using for quick access. Similarly, using more programs requires more memory.
Different types of RAM and memory modules are used in different devices. Knowing how different memory modules work is vital because they are the most important component of a computer or laptop. Gone are the days when there was just one type of RAM module that could be used on both PCs and laptops.
Desktop RAM and laptop RAM: an overview
It’s critical to understand the differences between desktop and laptop RAM modules. So, before we go into the differences between desktop and laptop RAM, let’s have a look at both memory kinds.
Desktop RAM (DIMM)
Desktop systems use memory modules known as Dual in-line memory modules (DIMMs). The DIMM type consists of
several memory chips on a single circuit board. DIMMs are standard memory types that are widely used in desktop computers.
DIMM modules are compatible with most modern desktop PCs with 64-bit data speed. In addition, they have replaced the old SIM (single in-line memory) modules that used a 32-bit memory path. In addition, DIMMs A transistor and capacitor pair are used in the DRAM memory classification. Of course, it works according to its name; it regularly refreshes memory to avoid losing its content.
Laptop RAM (SO-DIMM)
Laptops use system memory modules known as small outline dual in-line memory modules (SO-DIMMs). This is practically the skimmed version of DIMM. In addition, SODIMM use integrated circuits. Almost all modern laptops have SODIMM as their primary memory module.
They are quite small in size, and therefore are ideal for mobile versions of computers – laptops. SODIMM computers have about half the size of regular DIMMs. Because it would be impossible to put a desktop memory module into a small system, SODIMMs were created as a substitute for DIMMs.
Desktop vs Ram. Laptop RAM: the main differences
While both types of system memory modules perform the same functions, there are some differences.
RAM size matters
Desktop RAM is physically larger than laptop RAM. DDR4 memory modules in current PCs contain 240 pins, whereas laptop memory modules have 204 pins. The average length of a desktop RAM module is about 4.5 inches, and the average length of a laptop memory module is about 3 inches.
Therefore, the size difference is basically the physical length and pin configuration. Laptop RAM modules are about 50% desktop RAM modules.
Compatibility
As previously mentioned, desktops use DIMMs for system memory, whereas laptops use SODIMMs. These two motherboards are completely distinct and incompatible with one other. Previously, the laptop RAM module could be used on the desktop and Now Contrast. However, after the arrival of the new type of system memory, the scene has changed.
Therefore, Ram in desktops and laptops are not interchangeable due to their different architectures and configurations.
Upgradeability
While this is not an important factor, upgrades are a major concern for enthusiasts. A lot of laptop manufacturers mix RAM modules on motherboards without providing any additional slots for upgrades. Not all laptops do this, but the numbers are growing. With the desktop, you get more space for upgrades, and the flexibility to choose the RAM capacity as per your requirement.
Laptop manufacturers follow the path where the user receives limited control of his machine. The upgradability factor is not entirely related, but should be considered if we are comparing the two.
In a nutshell low, desktop rack, making the laptop rack, what, took a preference to the north of her form factor and structure of the Fed. The mandatory form, at least, her task is similar to the condition.
