What Is RAM And What Does It Do? [2021 Guide]

Random-Entry Reminiscence (RAM) is used for short-term storage of comparatively small quantities of essential information related to the functioning of laptop packages, together with the working system itself.

RAM is way quicker than SSDs or HDDs, however it’s a sort of risky reminiscence, which means that it might probably solely retailer information whereas it’s powered.

When constructing a gaming PC (or any PC, for that matter), there are a variety of various elements to contemplate, every of them very important for the correct functioning of the system as a complete. And a type of very important elements is RAM.

So, on this article, we’ll be specializing in RAM – what’s it? What does it do? What forms of RAM are there? How a lot of it do you want in a PC?

We’ll be answering all of these questions beneath, so in the event you’re focused on discovering out extra, learn on!

What Is RAM?

RAM For Gaming

Let’s begin with the fundamentals – what’s RAM?

Nicely, the acronym stands for Random-Access Memory, and it’s a sort of reminiscence used to briefly retailer comparatively small quantities of essential data that the CPU or the GPU want to have the ability to entry shortly in order that all the packages working on the pc would be capable of operate.

Furthermore, RAM is a kind of volatile memory, which implies that it might probably solely retailer information whereas it’s powered. If the ability provide is minimize off, no matter information was saved within the RAM is instantly misplaced. As such, it’s clear as to why RAM isn’t used for long-term storage and that its benefit lies in its pace which far exceeds these provided even by the quickest SSDs at the moment available on the market.

In essence, lets say that RAM is your laptop’s short-term reminiscence, whereas the HDD or the SSD can be the long-term reminiscence.

What Varieties Of RAM Are There?

DDR3 vs DDR4 vs DDR5 RAM

Like some other expertise, RAM has developed and superior considerably through the years. The origins of RAM really go all the way in which again to the Nineteen Sixties and the primary SRAM (static random-access reminiscence) chips. It was developed and utilized together with DRAM (dynamic random-access reminiscence) for nearly half a century since then.

Within the early Nineteen Nineties, nevertheless, we see the primary SDRAM chips, which stands synchronous dynamic random-access reminiscence. After which, in June 1998, Samsung launched the very first DDR SDRAM chip, the place DDR standing for “double information price”.

It’s from right here that DDR went on to dominate the market. In 2001, Samsung launched DDR2, and DDR3 adopted quickly after, in 2003. Nevertheless, DDR4 wouldn’t be launched till 2011, however it’s the dominant sort of RAM immediately. Now, DDR5 is simply across the nook, though it will likely be some time but earlier than it replaces DDR4 within the mainstream market.

It’s additionally price noting that one other sort of reminiscence was launched quickly after SDRAM, and that might be SGRAM – synchronous graphics random-access reminiscence. And alongside the primary DDR chips, Samsung additionally developed the very first GDDR chip, and as you may guess, the “G” within the acronym right here stands for “graphics”.

Very similar to “common” DDR, GDDR superior through the years, from the primary GDDR chips to the a lot quicker GDDR6 which you can see applied within the newest mainstream graphics playing cards.

Nevertheless, GDDR isn’t the one sort of graphics reminiscence that you simply’ll see applied in fashionable graphics playing cards. In 2013, SK Hynix launched the very first HBM(Excessive Bandwidth Reminiscence) chips, adopted in 2016 by HBM2 chips that have been since utilized by quite a lot of graphics playing cards.

Nevertheless, as a result of excessive manufacturing prices and the restricted advantages that top bandwidth provided by way of in-game efficiency, HBM2 by no means actually posed a problem to GDDR within the mainstream market, though it might probably provide vital advantages in workstations that run memory-intensive software program.

All in all, the present state of the RAM market isn’t anyplace close to as sophisticated as you may assume from all of the acronyms talked about right here. The overwhelming majority of PCs immediately use DDR4, and it gained’t be eclipsed by DDR5 for some time but. In the meantime, the overwhelming majority of graphics playing cards use GDDR – GDDR5 was dominant up till a couple of years in the past, and it has now been succeeded by GDDR6.

How A lot RAM Do You Want?

How Much RAM For Gaming

When constructing a PC, one of many widespread questions which can be typically requested is: simply how a lot RAM is sufficient?

If we’re speaking a couple of gaming PC, the overall consensus is that 16 GB is the candy spot for the time being. It’s greater than sufficient to run the newest video games and it’s pretty future-proof, too. For individuals who are on a decent funds, although, 8 GB of RAM will minimize it.

That mentioned, there is no such thing as a must spend additional on higher-capacity RAM sticks except you plan on utilizing the PC with some memory-intensive skilled software program that might really make the most of all that additional reminiscence.

On the opposite finish of the spectrum, if we’re speaking PCs that might solely be used for the naked fundamentals i.e., web shopping or multimedia, even 4 GB will be sufficient to cowl the PC’s reminiscence necessities. For sure, although, having extra RAM can all the time assist with multitasking.

How Quick Ought to Your RAM Be?

RAM Speed

Whereas the capability is unquestionably an important issue to remember when shopping for RAM, pace can’t be neglected both.

In the case of RAM, the pace is expressed in Hertz, very like the clock pace of a CPU or GPU. The upper the clock pace, the upper the information switch charges supported by the RAM module. In the present day, you’ll encounter DDR4 RAM modules with clock speeds that vary anyplace from 2133 MHz to a whopping 5100 MHz, however most mainstream DDR4 sticks are confined to the 2133-3600 MHz vary.

Now, the actual query is: how a lot does RAM pace have an effect on gaming efficiency?

The reality is: not that a lot. Sure, there may be positively a distinction, and although it is perhaps a bit extra noticeable in some video games that use quite a lot of reminiscence, it principally comes all the way down to a handful of frames. Fact be instructed, the distinction in efficiency can solely actually be noticeable if we’re speaking about triple-digit framerates and displays with excessive refresh charges.

So, all in all, in the event you’re involved about gaming efficiency, it’s all the time a greater concept to place extra money in direction of a more powerful GPU moderately than overclocked RAM.


And so, that might be about it for this text! Hopefully, you’ve discovered it useful and it has shed some gentle on any misconceptions you might need had concerning the function that RAM performs in a PC.

Should you’re constructing a brand new gaming PC for the time being, remember to try a few of our gaming PC builds, as you’re certain to search out one that matches your wants and your funds!
