Most individuals prioritize the CPU and GPU whereas constructing a gaming PC, as they’re chargeable for delivering probably the most efficiency, however overlooking different essential elements just like the RAM can result in PC bottlenecks. Actually, your PC’s RAM is simply as necessary as your CPU and GPU, particularly in CPU-bound eventualities.
When you’ve got weaker or slower RAM, your in-game body fee will take a success even in case you have the quickest and strongest CPU and GPU in your system. And if you do not have ample RAM for the sort of video games you play, chances are you’ll even encounter crashes. So, listed below are some essential indicators it’s best to look out for to find out whether or not your RAM is limiting your gaming PC’s efficiency.

7 things that could be causing your PC to bottleneck
Nothing is extra annoying than shedding efficiency, particularly when it may be averted. Listed below are some issues to examine in the event you’re having points.

Stuttering
Video games stutter even at excessive body charges
Your video games may run at over 100FPS with a quick CPU and highly effective graphics card, but when your RAM is not equally quick sufficient, you will not get a clean gaming expertise even when the body charges are excessive. You may doubtless encounter occasional body drops, hitching, and micro-stuttering, which might get fairly annoying actually quick.
It is value noting that your RAM acts as a high-speed knowledge buffer to your CPU. As an illustration, when a sport must load belongings like textures, environments, and character fashions, your CPU depends on the RAM to retrieve the info rapidly. But when your RAM is simply too sluggish, you may encounter intermittent freezes and stutters. It is doable that your RAM is quick sufficient, however it is not working at its rated speeds. So, it is value checking if you’ve enabled the XMP or EXPO profile in the BIOS.

Excessive RAM utilization
Regarding when you do not also have a sport working
It is comprehensible in case your PC makes use of a number of RAM whereas taking part in demanding AAA video games, but when your RAM utilization is excessive (60-70%) earlier than you even launch your favourite sport, likelihood is that you do not have sufficient RAM to run the sport correctly.
You need to use Job Supervisor’s Efficiency tab to watch your RAM utilization throughout primary duties like net shopping, video chatting, and many others. As an illustration, in case you have solely 8GB of RAM and your PC makes use of round 4GB for background apps, you’ll inevitably encounter issues like stuttering, sluggish asset loading, and crashes whereas taking part in trendy video games.

Disk utilization for digital reminiscence
Your PC depends in your storage drive to compensate
When your PC would not have sufficient RAM to deal with all of the duties, it usually makes use of the web page file (digital reminiscence) in your SSD or HDD to retailer knowledge. Though Home windows does this to keep away from crashes, your PC’s efficiency will take a noticeable hit each time it makes use of digital reminiscence as an alternative of bodily RAM. That is as a result of the RAM has a lot decrease latency in comparison with even the quickest SSDs.
Whereas gaming, you may encounter freezes or stutters when your PC makes use of your storage drive’s digital reminiscence, and the sport’s belongings will take considerably longer to load. To examine if so, you possibly can monitor your disk usage in Windows 11 utilizing Job Supervisor; you may discover it within the Efficiency tab. Including extra RAM will considerably cut back your PC’s reliance on digital reminiscence and enhance gaming efficiency.

Poor 1% and 0.1% low FPS
Your common FPS would not inform the entire story
FPS with (proper) and with out (left) AFMF in one of many scenes in Forpoken.
Most individuals have their eyes locked on the common FPS quantity whereas benchmarking video games, however sadly, that does not inform the entire story. The 1% and 0.1% low FPS are equally necessary, as they point out the bottom body charges you expertise 1% and 0.1% of the time throughout your gameplay. It’s possible you’ll overlook a possible RAM or CPU bottleneck by neglecting the 1% and 0.1% lows.
As we mentioned earlier, when your RAM is not quick sufficient to maintain up with the remainder of the elements, like your CPU and GPU, you may encounter body drops, which you may see within the 1% and 0.1% lows in the event you monitor your hardware using MSI Afterburner. You may anticipate the identical if you do not have ample RAM and your PC begins utilizing the web page file in your storage drive. Both method, I extremely advocate growing the RAM capability or upgrading to sooner DDR5 reminiscence to enhance your 1% and 0.1% lows considerably.
Your PC simply would not have sufficient RAM to deal with the sport
That is self-explanatory, however you’ll encounter crashes if you do not have sufficient RAM to run the video games you play. It is usually a matter of time earlier than you crash to the desktop with an error message that reads “out of reminiscence.” Because of this I at all times counsel reviewing the minimal and really helpful system necessities earlier than buying PC video games.
Most trendy video games require 16GB of RAM to run easily, and in the event you solely have 8GB, anticipate to make some compromises. You may strive closing the background apps that devour your RAM whereas gaming or allocate extra digital reminiscence on Home windows to assist with the crashes to a sure extent.
Your RAM is simply as necessary as your CPU and GPU
A high-end CPU and GPU do not matter a lot when your RAM just isn’t on par. Whether or not your system would not have ample RAM or it is simply not quick sufficient to your CPU to retrieve knowledge, you’ll encounter issues like stuttering, crashing, FPS drops, texture pop-ins, and so forth.
For a great gaming expertise, your gaming PC wants at the very least 16GB of RAM. I counsel pushing for 32GB of RAM so you do not have to take care of reminiscence leak-related crashes. And in the event you’re constructing a brand new PC in 2025, it would be sensible to spend your hard-earned cash on DDR5 reminiscence over DDR4 because it’s considerably sooner.
