Computer Memory Upgrade Dundee

You’ve got fifteen browser tabs open, Word running in the background, and you’re trying to join a Teams call. Everything freezes. The cursor stops moving. You wait. Eventually it catches up, but by then you’ve missed half the meeting and lost whatever you were typing.

That’s what happens when your computer runs out of RAM. It’s the single most common cause of a computer that was perfectly fine two years ago but now can’t keep up with how you use it. The good news is that a RAM upgrade is one of the cheapest and quickest hardware improvements you can make, and the difference is usually obvious from the moment you restart.

We check compatibility, source the right spec, fit it, and test it at our Perth Road workshop. Most desktop upgrades are done same day. Combined with an SSD upgrade, it’s the two-part fix for a slow computer that costs a fraction of buying new.

Signs Your Computer Needs More RAM

Your computer has a few consistent ways of telling you it’s struggling for memory:

• Slow startup. Takes minutes instead of seconds to reach your desktop and become usable after logging in.
• Freezing during multitasking. Everything locks up when you try to run multiple programs at once. Switching between open windows takes seconds instead of being instant.
• Programs crashing. Applications close without warning, especially memory-heavy ones like Chrome, Photoshop, AutoCAD, or video editing software.
• Constant hard drive thrashing. You can hear the hard drive working constantly even when you’re not doing anything heavy. That’s Windows using the hard drive as overflow memory because it’s run out of actual RAM.
• Fans ramping up during basic tasks. The processor works harder when it’s constantly managing insufficient memory, which generates more heat.

When it’s NOT a RAM problem: if your computer is running hot enough to shut itself down, making clicking noises from the hard drive, or riddled with pop-ups, you’ve likely got a different issue. Overheating, a failing hard drive, or malware cause similar symptoms. We diagnose which problem you actually have before recommending anything.

How Much RAM Do You Actually Need in 2026?

RAM requirements have increased significantly. What was fine three years ago isn’t enough any more, partly because Windows 11 itself uses more memory, and partly because browsers, video calls, and everyday applications have all become hungrier.

4GB: genuinely inadequate in 2026. Windows 11 alone uses roughly 2.5GB at idle, leaving barely enough for a single browser tab and a document. Open Chrome with a few tabs and you’ve used all 4GB before you’ve started doing any actual work. If your computer has 4GB and it’s driving you mad, this is almost certainly why. Upgrading from 4GB to 16GB is the single biggest difference you’ll notice from any RAM upgrade.

8GB: the minimum for comfortable everyday use. Fine for web browsing, email, documents, and streaming. Starts to struggle when you have lots of browser tabs open alongside other programs, or when you use video calling while working on anything else. 8GB was the standard for years, but it’s now entry-level.

16GB: the sweet spot for most folk in 2026. Handles heavy multitasking, design software, multiple browser tabs, video calls, and casual gaming without breaking a sweat. You can have Word, Excel, Chrome with twenty tabs, Spotify, and a Teams call all running simultaneously and the machine won’t flinch. This is what we recommend for students, professionals, and anyone who finds themselves regularly frustrated by slowdowns.

32GB: for gaming at high settings, video editing, 3D rendering, large spreadsheets, running virtual machines, or professional creative work. More than most home users need, but essential for anyone whose work involves handling large files or resource-heavy applications.

DDR4 vs DDR5: Understanding RAM Types

Your computer takes one type of RAM and it can’t accept any other. DDR4 and DDR5 sticks are physically different shapes with different pin configurations. You can’t put DDR4 into a DDR5 slot or vice versa. The slot is keyed differently to prevent it.

DDR4 is still the most common type we fit. Most computers from roughly 2015 to 2022 use DDR4. It’s widely available, proven, and does the job well for the vast majority of use cases. DDR4 comes in different speeds (2133MHz, 2400MHz, 2666MHz, 3200MHz being common). Your motherboard has a maximum speed it supports, and we match the RAM to that specification.

DDR5 is the newer standard, found in computers from roughly 2022 onwards. It’s faster than DDR4 with speeds starting at 4800MHz and going much higher. You’ll notice the difference in specific workloads like gaming at high refresh rates, video editing, and professional applications. For general everyday use, both perform well. DDR5 has been more expensive than DDR4, and in 2026 the global DRAM shortage driven by AI data centre demand has pushed prices up further across both types.

DDR3 is still found in older machines (pre-2015). We can source DDR3 modules, though availability is more limited than DDR4.

Not sure which your computer takes? Don’t worry. That’s part of what we check before ordering anything. We identify the exact type, speed, and maximum capacity your motherboard supports so you get the right spec first time.

Can Your Computer Be Upgraded?

Not all computers can have their RAM upgraded. Here’s what determines whether yours can:

Soldered RAM. Some laptops, particularly ultrabooks and MacBooks, have RAM soldered directly to the motherboard. There are no removable sticks and no empty slots. Whatever it shipped with is what it has for life. Many Apple MacBooks from 2012 onwards, most Microsoft Surface devices, and many thin-and-light ultrabooks fall into this category. We’ll tell you straight if your machine can’t be upgraded rather than wasting your time.

Maximum capacity. Every motherboard has a maximum amount of RAM it supports. A machine with a 16GB maximum can’t be upgraded to 32GB regardless of what you put in the slots. We check this as part of the compatibility assessment.

Available slots. Desktops typically have two to four RAM slots. Laptops usually have one or two. If all slots are filled with smaller sticks, we replace them with larger ones. If there’s an empty slot, we can often just add another stick.

Dual channel. RAM works fastest when installed in matched pairs (same capacity, same speed, same manufacturer). Two 8GB sticks perform better than a single 16GB stick because the system can read from both simultaneously. We always configure for dual channel where possible.

Laptop RAM Upgrades

Laptops use a smaller format of RAM called SODIMM. It’s physically different from desktop RAM and not interchangeable. Some laptops are straightforward to upgrade (remove a panel on the bottom, swap the sticks), while others require partial disassembly to reach the memory slots.

The accessibility varies hugely by manufacturer and model. Lenovo ThinkPads are generally easy. Many Dell and HP business laptops have accessible memory slots. Gaming laptops almost always have upgradeable RAM. Ultra-thin models from any manufacturer are the ones most likely to have soldered memory.

Bring your laptop in and we’ll confirm whether it can be upgraded, what it currently has, what it can take, and what we’d recommend based on how you use it. No point guessing when we can check in five minutes.

Desktop and Gaming PC Upgrades

Desktop computers are much more accommodating. Most have two to four RAM slots with room to expand, and some gaming and workstation boards have eight. The physical installation is simpler than laptops because there’s more space to work in, and desktop DIMM modules are standardised across manufacturers. You can often add more RAM to a desktop without removing what’s already there, which isn’t always possible in a laptop with only one or two slots.

For gaming desktops and workstations, RAM speed matters as much as capacity. Faster memory can improve frame rates in games and reduce rendering times in creative applications. Many motherboards support XMP profiles that allow RAM to run at higher speeds than the default specification. We configure this as part of the upgrade so you get the full performance benefit of the RAM you’ve paid for.

Desktop upgrades are usually done same day because the installation is quick and we stock common DDR4 and DDR5 modules.

Our Upgrade Process

Compatibility check. We identify your current RAM (type, speed, capacity), check how many slots you have and how many are free, and confirm the maximum your motherboard supports. We won’t recommend RAM your machine can’t use.

Sourcing. We use quality, tested modules from reliable manufacturers. No generic unbranded sticks that might fail in six months. We match the specification exactly to what your machine needs.

Installation. Proper handling (static-safe), correct slot placement for dual channel, firm seating, and secure clips. Takes minutes on a desktop, slightly longer on laptops that need disassembly.

Testing. We boot up, confirm the BIOS recognises the full amount, run a memory diagnostic to check for faults, and do a real-world test to make sure everything is stable under load. You collect a machine that’s been verified working, not just assembled and hoped for the best.

System cleanup. While we’ve got it, we tidy up startup programs and background processes so you get the most out of the extra memory. No point adding RAM if twenty unnecessary programs are loading at startup and consuming it all before you’ve even logged in.

Business Systems

Computer manufacturers ship business machines with the minimum RAM they can get away with to keep the purchase price competitive. A machine that shipped with 4GB or 8GB worked fine when it was new, then gradually got slower as Windows updates, Office updates, and security software all started demanding more memory. We see this constantly with office machines that are three to four years old. The hardware is perfectly fine. It just doesn’t have enough memory for the software it’s now running.

For businesses with multiple machines, we handle the upgrades efficiently. Same spec across every workstation, tested identically, consistent performance. If you’re not sure whether your office machines need more RAM or a different fix entirely, we can assess the lot and tell you what will actually make a difference.

What to Expect

Bring it in. 153 Perth Road, Dundee. No appointment needed. If you know your computer’s model number, that helps us check compatibility faster, but it’s not essential.

We check and quote. We confirm what RAM your machine takes, what it currently has, what it can take, and what we’d recommend. Clear quote before we do anything.

We fit and test. Install the RAM, verify it’s recognised, run diagnostics, clean up startup programs. Desktop upgrades are usually done same day. Laptops that need disassembly may take a little longer.

Warranty: 90-day warranty on all memory upgrades. If the RAM develops a fault or causes instability, bring it back and we’ll sort it.
