Crucial System Scanner was designed to identify a Windows computer and suggest Crucial RAM or storage upgrades. A scanner report can be useful, but it is not a complete compatibility check and this guide does not claim a new hands-on scanner test. Verify the computer’s exact model, service manual and supported parts before buying.
What has changed for Crucial products?
Micron announced its exit from the Crucial consumer business in December 2025, with consumer-channel shipments continuing through February 2026 and ongoing warranty service and support. That does not prove that every support tool has disappeared, but old product recommendations, stock and purchase links should not be assumed current.
If the official scanner page is unavailable or does not provide a supported download for your system, use the manual-based checks below. Do not download an executable from an unrelated mirror simply because it uses the Crucial name.
If the official scanner is offered for your PC
- Reach the scanner through Crucial’s official support site and read the stated system requirements and privacy information.
- Download only the official file. Check the publisher and source before allowing it to run.
- Save the detected computer model and specifications. Treat suggested products as candidates, not as a complete list of every compatible brand.
- Compare each proposed upgrade against the computer manufacturer’s service manual before ordering.
Identify your PC without a scanner
In Windows, open System Information by pressing Windows + R, entering msinfo32 and pressing Enter. Record System Manufacturer and System Model. For a custom desktop, also identify the motherboard’s exact model and revision. A laptop family name alone can hide different memory and storage configurations.
Task Manager’s Memory page can offer useful installed-memory information, but its slot count should not replace the service manual or a supported physical inspection. Soldered memory may not be replaceable.
RAM compatibility checklist
- DDR generation and electrical type: DDR4 and DDR5 are not interchangeable.
- Form factor: desktop DIMM, laptop SO-DIMM or another supported format.
- Maximum capacity, module organization and the supported number of slots.
- ECC/registered versus unbuffered requirements and the system’s supported memory speeds.
Our DIMM versus SO-DIMM compatibility guide explains these distinctions. Matching pin count or a marketing frequency alone does not guarantee an upgrade will work.
SSD compatibility checklist
Check the storage interface, supported M.2 lengths, SATA versus NVMe requirements, available slot, component clearance and any heatsink restrictions. A drive that fits mechanically may use an interface the slot does not support. See our M.2 heatsink fit guide for clearance checks and our MBR versus GPT guide when preparing a supported boot drive.
For a supported ASUS motherboard, our M.2 Q-Latch installation guide explains the separate mounting and heatsink checks. The latch does not change the slot’s supported SSD interface.
After installing an upgrade
Back up important data first and keep encryption recovery information available. Verify that firmware and the operating system detect the new capacity, then test normal workloads. If instability starts after the change, return to a known working configuration and follow the PC-freezing checklist rather than assuming the scanner’s recommendation rules out a compatibility problem.
