Random Access Memory or RAM is a volatile storage device, meaning it stores data temporarily while you are running apps and processes on the computer.
Simply put, if you consider your computer as a brain, the RAM would be its short-term memory.
Its purpose is to allow the CPU to access necessary data for doing a task more quickly without delving into slower, long-term storage devices, which will allow the system to run faster and smoother.
Therefore, the presence of RAM is essential for efficient multitasking, like keeping various applications running at once or playing games without interruptions and lags by storing all the relevant assets it needs to access quickly.
Your computer continuously overwrites and refreshes your RAM, and it resets once the system is restarted.
When you check out your RAM specs, you will run into terms like RAM brand, type, form factor, size, speed, voltage, and latency that describe the device.
Continue reading to understand what each of these terms means and get to know your RAM better.
1. RAM Form Factor
RAM modules are available in two primary and standard form factors:
- Dual In-Line Memory Module or DIMM: The DIMM is the RAM form factor used for desktop computers, and it refers to the physical size of the RAM stick, which is bigger for desktops.
The standard length is 133.35 mm for DIMMs.
- Small Outline DIMM or SO-DIMM: SO-DIMM RAM modules are for laptops and compact computers, in general.
They’re almost half as small as DIMMs, at 67.6 mm in length.
2. RAM Brand
Like any PC-related device, memory sticks have different manufacturers and assemblers with different brand names.
It’s a well-known fact in the computer community that two different manufacturers can make the same RAM stick and package them slightly differently.
However, no one can ever be sure of this because the brands don’t publicize all their RAM specs.
3. RAM Type
RAM sticks have improved and gained more enhanced features like any other technology.
There are five main RAM types or generations for the DDR SDRAMs (Double Data Rate Synchronous Dynamic RAM) commonly in use today:
- DDR1 SDRAM (2000)
- DDR2 SDRAM (2003)
- DDR3 SDRAM (2007)
- DDR4 SDRAM (2014)
- DDR5 SDRAM (2020)
There is no backward compatibility between the different RAM types because each uses a different number of pins.
Therefore, you can’t fit one into a slot made for the other.
4. RAM Size
RAM size refers to the capacity of the RAM module, determining how much data it can store.
RAM sticks come in different sizes, varying from 2 GB to 32 GB.
If you get two 2GB RAM sticks, your computer will have a total of 4 GB of memory space.
5. RAM Speed
RAM speed or frequency refers to the number of cycles a RAM module can perform every second.
The more the frequency, the more data your RAM can read and store.
This results in smoother system performance.
RAM manufacturers state their product’s frequency in Megahertz (MHz).
For instance, if you see the number 3,600 MHz in a RAM’s specs, you’ll know that it can perform 3.6 billion cycles every second.
6. RAM Latency
Latency is the time it takes a RAM stick to respond to the system commands by accessing a specific set of data that it has previously stored.
The number written next to “CL” in a RAM stick’s specifications will indicate latency.
For example, a CL16 memory module will take 16 cycles to respond to a command, so the lower the latency, the faster the memory module will perform.
7. RAM Voltage
The power that the DRAM modules should receive to work smoothly is referred to as their voltage.
Different RAM sticks have different voltages ranging from 1 volt to 1.4 volts.
Why Would You Want To Know Your RAM Specs?
If your system is getting slow and sluggish due to a lack of RAM, you might upgrade it and boost the performance.
You might even want to upgrade your whole system to be able to play more demanding games or run heavy applications.
Therefore, you need to know what RAM specs you’ll need and what will be compatible with your current build.
Also, knowing your RAM specs will help you tweak the memory settings inside the BIOS or UEFI.
