Does More RAM Make Your Computer Faster?

Is it better to have more RAM or faster RAM

Answered By: Kyle Price Date: created: Aug 03 2021

Faster RAM will give your PC better performance in certain specific benchmarks, but in terms of actual benefit to most users, having more RAM available is almost always better than having faster RAM. Graphics cards include their own memory, so games aren’t majorly affected by system RAM speed.

Old vs. New Memory Standards

Older computers may not support newer memory standards. For example, if your computer uses DDR3 and you want to install DDR4, it won’t work because these use different clocking technologies that aren’t compatible. In the past, there were exceptions to this rule with processors and motherboards that allowed one type or the other to be used within the same system. However, as memory controllers have been built into processors for improved performance, it’s no longer possible.

How can I increase speed of my computer

Answered By: Nathan Cooper Date: created: Dec 25 2021

Here are seven ways you can improve computer speed and its overall performance.

  1. Uninstall unnecessary bloatware.
  2. Limit the programs at startup.
  3. Add more RAM to your PC.
  4. Check for spyware and viruses.
  5. Use Disk Cleanup and defragmentation.
  6. Consider a startup SSD.
  7. Take a look at your web browser.

Get an SSD Instead


If the bottleneck isn’t your RAM, then you have a few other choices. The number one option is to upgrade to a solid-state drive (SSD) if your PC still has a hard drive. Even if you do increase the RAM, there’s simply no better upgrade for a PC than moving it from a hard drive to an SSD.

Even an older SATA III SSD, like the Samsung 860 Evo, will provide a noticeable increase in response times and general performance. If the motherboard accepts NVMe drives, then the performance improvements will be even more noticeable.

Don’t throw out that old hard drive, either—you can use it as secondary storage if your PC still has room for it. You can also put it in an external hard drive enclosure and use it that way (after copying your personal files and reformatting, of course.)

3. Understanding the Virtual Memory Concept

I do not want to make things complicated, but without understanding the virtual memory concept offered by the OS, there is no point in moving forward.

In layman’s terms, Virtual Machine is a space on hard disk that is used by the operating system when the RAM runs out of space. This leads the OS to swap the running (inactive) app on the hard disk, swapping it back after it becomes active.

The process of swapping in and out are slow and eventually hampers the performance of the machine. In other words you can say that if your computer lacks the random access memory (RAM) needed to run a program or operation, Windows uses virtual memory to compensate. Virtual memory combines your computer’s RAM with temporary space on your hard disk. When RAM runs low, virtual memory moves data from RAM to a space called a paging file.

To eliminate or minimize virtual machine swapping, ensure that your system has enough RAM and in case you find that your machine has a low ram and does frequent virtual machine swaps(i.e., become slow), getting a RAM will surely increase the performance of your PC or computer.

Bottleneck #2: Internet Speed

What is the most frequently used application on your computer? Once the answer would have been Microsoft Excel or another offline application. But the soaring popularity of cloud-based apps has drastically altered usage habits. From Google Docs to Onedrive, Facebook to Youtube, you probably spend most of your time online using a web browser.

And if you find internet browsing on Chrome to be slower than usual, don’t rush to declare the RAM capacity to be the culprit. The problem might possibly be poor internet connectivity.

Apart from the quality of the network itself, it is the Wifi card that decides the speed of your internet connections. For most notebooks, this card comes built into the motherboard itself. If you are using an older PC, consider upgrading the Wifi card first.

What does upgrading RAM do?

Upgrading RAM gives your computer the critical resources it needs to temporarily shuffle data from the hard disk to the CPU to process it. Even the fastest solid-state drives (SSD) are sluggish compared to how quickly RAM can get your computer the information it needs. Without RAM — or without sufficient RAM for whatever it is you’re doing — your computer would become unbearably slow or not even work at all.

Generally, people add more RAM in order to:

Notice that all the reasons listed above directly relate to making your PC faster and more powerful. That’s the primary reason to upgrade RAM.


More RAM doesn’t necessarily make your computer work faster. The bottleneck usually stems from a slow hard disk drive or an outdated Wi-Fi card, preventing the RAM from being utilized to its fullest.

Even if you are a gamer, you will see more of an impact by upgrading the GPU than the RAM. The memory is only used to hold the loaded assets; it is the job of the graphics card to actually process them per frame.

Adding RAM is a no-brainer when your laptop or desktop computer is sitting at just 8 GB or has a single memory module. In any other scenario, take a good look at your system’s specs to decide on the upgrades it needs.

Is XMP Enabled?

DIY desktop PC builders might not be maximizing the performance capabilities of their current RAM. Most people who build their own PCs have likely done this already. In the motherboard’s BIOS settings, you can activate something called an eXtreme Memory Profile (XMP). If your PC has an AMD processor, you might see DOCP instead.

XMP is an Intel technology that’s, ostensibly, an overclocking tool. However, if you just turn it on in the BIOS without tweaking any of the manual settings, it’ll let the RAM run at the speed for which it’s rated, rather than the slower default.

Check your RAM upgrade

After installing new RAM, turn your computer on and check its RAM again to make sure that everything is working properly. You can head back to the Task Manager as described above, or you can right-click This PC from your desktop and select Properties.

Look for your computer’s memory information and ve

Look for your computer’s memory information and verify that the total amount of memory shown matches the RAM you’ve just installed. If so, congratulations — you’ve successfully upgraded your RAM!

Anytime you’ve installed new internal components, consider stress-testing your PC to assess their stability.

How much RAM do you need?

As of this writing in 2021, 16 GB is considered the sweet spot for price-to-performance considerations in the context of mainstream work-related computing tasks. If you have several applications running simultaneously and a dozen Chrome tabs open you still should have plenty of headroom before you notice any lag in performance.

Anything more than 16 GB would make sense for workstation computers that are used for graphics rendering, scientific modeling, and CAD applications. It is not uncommon for 3D design workstations to have up to 32 GB of RAM.
