How To Choose Right RAM?

RAM’s function is to store the short-term data needed by a PC to function correctly. However, unlike a hard disk drive or a solid-state drive (SSD), RAM is erased when the system is rebooted.

In contrast to a “non-volatile” HDD or SSD, RAM is referred to as “volatile memory” since it only retains data when power is applied. While in use, programs are loaded into RAM, but they are permanently stored on a storage device (until deleted).

In order to run programs and perform tasks, computers require instant access to temporary data. Art assets, for example, must be retrieved quickly in modern PC games. In games, RAM is used to read and write data because it is so much faster than a storage device.

What RAM Is Compatible with Your Motherboard?

RAM capacity and frequency aren’t as important as ensuring that the RAM is compatible with the motherboard and processor. The improper sort of modules won’t operate, and RAM with the wrong specifications for your PC may underperform if they’re installed.

Module Type

Memory sticks, also known as memory modules, are used to fill up the available memory slots on a computer’s motherboard. To put it another way, you can’t use RAM that isn’t compatible with your system.

DDR4 RAM is supported by contemporary motherboards. The previous version of SDRAM, DDR3, is not to be confused with DDR4. You can’t swap out 8GB of DDR3 for 16GB of DDR4, because they aren’t interchangeable.


Computers make use of SDRAM, a form of random-access memory (Synchronous Dynamic Random Access Memory). DRAM that is labeled “synchronous” has its clock frequency matched to that of the processor. For example, SDRAM’s power consumption has decreased, its transfer speeds have accelerated and its stability has improved.

Modern computers use DDR4 SDRAM, which is the current standard. This is the fourth generation of DDR technology, which replaced SDR (Single Data Rate) SDRAM. DDR4 has quicker data transfer rates, higher capacity, and lower voltages than the previous generation of DDR memory.

When building a new PC or updating RAM in a modern system, you’ll most likely be working with DDR4 SDRAM, the current standard.

We need to know: Why isn’t DDR4 compatible with DDR3? Because it has varied timings (see below), voltage, and number of pins, among other features. It is impossible for DDR4 modules to slide into DDR3 slots because the key notch on DDR4 modules is positioned after a different pin than that of the DDR3 modules.

To find compatible memory, there are a number of simple methods. A system profiling tool or an online memory compatibility tool are all good places to start.

Form Factor

DIMM Sticks of (Dual in-line memory module) RAM are suited for desktop motherboards and are larger in size.

SO-DIMM Mini-ITX motherboards, Intel® NUC mini-PCs, and some Mini-ITX small form factor (SFF) motherboards use (compact outline dual in-line memory module).

Important RAM Specs

  • Capacity: Gigabytes are the unit of measurement (GB). Applications can store more data if the storage device has a bigger capacity. More programs can operate at the same time on a bigger capacity, and games can store more temporary data.
  • Speed: Mega transfers per second (MT/s) are often referred to as megahertz (MHz), despite the fact that this is a separate measurement from clock speed. Faster read and write response times are indicated by higher speed ratings, which equate to better performance.

What Type of RAM Is Right?

In the end, the amount of RAM you need for gaming will depend on your budget and your specific needs. Make sure the RAM’s parameters match your personal requirements before making a purchase.

In order to get the best performance out of your system, it’s vital to balance the amount of RAM with the rest of its components.
