How Much Does a Laptop RAM Upgrade Cost? (And Can Yours Even Be Upgraded?)

How much does a laptop RAM upgrade cost? The short answer

For a common upgrade — 8GB to 16GB, or 16GB to 32GB, on a laptop with standard SODIMM slots — expect roughly £60–£140 including the memory module and our fitting, as of November 2026. DDR4 SODIMM modules are cheaper than DDR5; the exact figure depends on capacity, speed and the memory market, which moves weekly, so we quote current pricing on every job.

You can drop the laptop off at our Durham Street workshop, or we'll collect and deliver across Portsmouth for £10 each way. Student and NHS discounts apply.

But the honest answer starts with a question the price guides never ask: can your laptop even be upgraded? Because there are three kinds of laptop in the world, and which one is sat in front of you decides everything — including whether any money changes hands at all.

One more thing before you budget: RAM supply is already under pressure, and we explain in our latest post why upgrading your PC now beats waiting until the new year — that £60–£140 range is more likely to drift up than down.

First, find out which of three laptops you have

Every laptop we see falls into one of three camps. Here's how to tell which one you own.

Outcome 1: soldered RAM — no upgrade, full stop

The memory chips are soldered directly to the motherboard. There's no slot, no module, nothing to swap. The only "upgrade" is a new motherboard, which costs more than the laptop is worth.

Most thin ultrabooks are built this way, and every Apple Silicon MacBook — M1 onwards — has soldered RAM. If that's you, the honest answer is that no shop in Portsmouth can upgrade your RAM, and we'd rather tell you that than take the job. MacBook owners are better off having a Mac repair conversation about the machine as a whole.

Outcome 2: one free SODIMM slot — partial upgrade

Some laptops have a chunk of RAM soldered (often 8GB) plus one empty SODIMM slot. You can add a module to the empty slot, but you can't remove the soldered part.

So an "8GB" laptop becomes 8GB + 16GB = 24GB, not a clean 32GB. It's a real upgrade — often the best value per pound — but the capacities are slightly awkward, and it's worth knowing before you budget.

Outcome 3: two SODIMM slots — the easy case

Both modules come out, both can be replaced. Most standard laptops from the last decade are built this way, and this is where the £60–£140 figure applies cleanly.

How to check which one you have

Two quick routes:

• The model number. It's usually on a sticker on the underside (e.g. "HP Pavilion 15-eh1xxx"). Look it up against the manufacturer's spec sheet — it'll say "8GB soldered + 1 SODIMM slot" or "2 SODIMM slots" or nothing at all.
• Task Manager. In Windows, press Ctrl+Shift+Esc, go to Performance > Memory, and look at "Slots used" bottom right. Two of two means both slots are occupied; one of two means there's a free slot.

The catch: Windows doesn't always report soldered RAM correctly — it can show one slot "used" on a machine that actually has soldered memory plus an empty slot, or vice versa. The reliable route is a physical check. Ring us on 02392 733174 with your model number and we'll tell you which camp you're in before you spend anything — or bring it in and we'll look inside.

What a RAM upgrade actually fixes

More memory solves one specific problem: not enough memory. Here's what that looks like in practice.

• Multitasking. Switching between Word, Teams, a browser and a spreadsheet without the machine grinding every time you alt-tab. On 8GB, Windows runs out of room and starts "swapping" — copying memory to disk, which is hundreds of times slower.
• Browser tabs. Chrome or Edge with 20+ tabs open is the classic 8GB killer. The laptop's fine in the morning and crawling by lunchtime, and closing tabs brings it back — that's memory pressure, not a failing machine.
• Photo and light video work. Lightroom, Photoshop and similar tools are memory-hungry. 16GB is the practical floor for students on media courses; on 8GB, Lightroom alone can eat most of it before you've opened a single image.
• The tell-tale symptom: the laptop is fine with one app open but stutters the moment you open a second or third.

8GB is the baseline problem we see most across the counter. It was fine in 2020. In 2026 — with modern Windows, modern browsers and the background AI processes Windows 11 now runs by default — it's genuinely tight. Trimming the AI cruft helps a little, as we covered in our post on disabling Bing AI, but in our workshop experience the real culprit behind a machine that's still slow is usually a mechanical hard drive or 8GB of RAM that's full under normal use.

What a RAM upgrade won't fix

This is the part most price guides skip, and it's the most common misdiagnosis we see.

A slow mechanical hard drive is the number-one cause of "slow laptop" complaints in our workshop — and more RAM won't touch it. If your symptoms are:

• slow boot (minutes, not seconds),
• programs taking ages to open, even the first one,
• everything laggy with nothing else running,

…that's the drive, not the memory. It's an SSD upgrade job, and it's the single biggest transformation we can do to an older laptop. Most laptops we see from roughly the last five or six years take an NVMe SSD; older machines usually take a 2.5-inch SATA SSD instead.

Often the right answer is both: SSD plus RAM together turns a five-year-old machine into something genuinely usable, for well under the price of a new laptop.

Also worth saying: RAM won't fix a failing battery, overheating, or a machine bogged down with malware — that last one is a virus and spyware removal job, and adding memory to an infected machine just makes the malware run faster.

Honest pricing by scenario

Here's how the three outcomes shake out in money terms, as of November 2026. Treat these as ballparks — memory pricing moves weekly and we quote current figures on every job.

A note on the soldered-RAM row: if the machine is also slow because of a mechanical hard drive, the SSD swap is still absolutely worth doing — the drive is upgradeable even when the memory isn't. If it's just underpowered, we'll say so honestly rather than take your money.

Why November is when this bites

Every November, the slow-machine complaints spike in our workshop. Usage hours go up as everyone moves indoors, term is in full swing, and the autumn Windows updates have landed.

• Students: coursework loads, a dozen browser tabs and Teams running all day expose 8GB machines that coped fine in September.
• NHS staff: laptops that get hammered all shift and then get the blame for being slow.

A RAM upgrade done now carries you through the academic year and beyond. It's a £60–£140 fix against a £500+ replacement — and with our student and NHS discounts, the maths gets better still.

When we'd tell you not to bother

Honesty is cheaper for everyone in the long run. We'd steer you away from a RAM upgrade if:

• The RAM is soldered with no slot. No upgrade, full stop. On a MacBook, that's a Mac repair conversation about the machine as a whole, not a memory job.
• The laptop can't run Windows 11 securely. The hardware line is roughly Intel 8th-gen / Ryzen 2000 plus TPM 2.0 and UEFI Secure Boot — machines from about 2018 onwards mostly qualify, as we set out in our Windows 11 end-of-support guide. Below that, the machine has a limited future regardless of how much RAM you pour into it, so check the hardware line before spending. If a fresh Windows install is what it needs, our Windows OS installation service covers it.
• The machine is over roughly eight years old. The money usually goes further towards a replacement or one of our custom builds.
• The real problem is a failing drive or malware. More RAM just hides the symptom. We diagnose first, quote second.
