Finding compatible memory for your laptop shouldn’t be complicated. Our free Laptop Upgrade Compatibility Checker covers 3,195+ laptop models across 18 major brands — instantly showing you exactly which RAM, SSD, charger, and dock upgrades are compatible with your specific machine.
With Crucial’s System Scanner being discontinued as Micron exits the consumer market, our checker is the most comprehensive free alternative available in 2026.

- Visit the checker: Go to our Laptop Upgrade Compatibility Checker
- Search your model: Type your laptop brand and model name (e.g., “Dell Latitude 5530” or “ThinkPad T480”)
- View results: Instantly see compatible RAM type, maximum capacity, SSD form factor, charger wattage, and dock compatibility
- Shop upgrades: Use the direct links to find compatible parts at the best prices
What the Checker Covers
RAM Compatibility
The checker tells you the exact RAM type your laptop supports — DDR4 or DDR5, SO-DIMM form factor, maximum speed rating, and maximum capacity per slot. It also shows whether RAM is soldered (non-upgradeable) or uses removable SO-DIMM slots.
SSD Compatibility
Find out whether your laptop uses M.2 NVMe, M.2 SATA, or 2.5-inch SATA drives. The checker shows the physical size (2230, 2242, or 2280), interface type, and PCIe generation supported.
Charger Compatibility
See the correct wattage and connector type for your laptop — whether it uses USB-C Power Delivery, a proprietary barrel connector, or a manufacturer-specific charging port.
Dock Compatibility
Check whether your laptop supports Thunderbolt 3, Thunderbolt 4, USB-C DisplayLink, or proprietary docking solutions.

Why Use Our Checker Instead of Crucial’s Scanner?
Crucial’s System Scanner was the go-to tool for checking memory compatibility for over a decade. However, with Micron discontinuing Crucial’s consumer products in 2026, the scanner’s recommendations now point to products that are increasingly difficult to buy. Our checker offers several advantages:
- Brand-neutral recommendations: We show compatible specs from all major brands (Kingston, Corsair, G.Skill, Samsung, SK Hynix), not just one manufacturer
- UK pricing: Direct links to Amazon and other UK retailers with current pricing
- More than just RAM: Our checker covers SSDs, chargers, and docks — not just memory
- Always up to date: New models are added regularly as manufacturers release new laptops
- No download required: Works entirely in your browser — no software to install
Frequently Asked Questions
Is the compatibility checker really free?
Yes, completely free with no signup required. Just visit the checker page and search for your laptop model.
How accurate is the compatibility information?
Our database is compiled from manufacturer specifications, service manuals, and hands-on testing. We verify RAM type, maximum capacity, SSD form factor, and other specs against official documentation for every model listed.
My laptop model isn’t listed — what should I do?
If your specific model isn’t in our database, try searching for a closely related model in the same series. For example, if the Latitude 5540 isn’t listed, the Latitude 5530 likely uses the same RAM type. You can also check our brand-specific upgrade guides for general compatibility information.
Can I use the checker for desktops?
The checker currently focuses on laptops. For desktop RAM compatibility, check our RAM Compatibility Guide or search for your specific desktop model in our guides section.
What if Crucial RAM is still the cheapest option?
If you can still find Crucial DDR4 or DDR5 at a good price, it’s perfectly fine to buy it — the hardware is excellent. Our checker simply ensures you have options from multiple brands so you can find the best deal.

How we verify this guide
We cross-reference compatibility figures against manufacturer specifications where available, official service manuals, and the standards that govern fit — memory type and speed (DDR4 / DDR5 / LPDDR5), maximum supported capacity and slot count, SSD form factor and interface (M.2 2280, NVMe PCIe vs SATA, keying), and charger wattage and connector (USB-C Power Delivery, GaN). We’re explicit about soldered or non-upgradeable parts, prioritise primary sources over retailer listings, and re-verify the data on a regular cycle. More on our method →
