Yes, you can add an NVMe SSD or replace RAM if your computer supports the specific drive and memory you choose. Check the exact computer or motherboard model before buying: an M.2 socket does not automatically support NVMe, and RAM must match the system’s type, form factor, capacity limits and slot rules.
Check compatibility before you buy
Find the computer’s exact model, or the motherboard model for a desktop, and consult its service or owner’s manual. Record your existing memory and storage configuration, then check each item below.
- NVMe support: Confirm the M.2 slot supports PCIe NVMe, not just a different M.2 protocol. Intel notes that PCIe NVMe requires system or motherboard vendor support and calls for a PCIe x4-or-higher connector. Check Intel’s NVMe installation guidance and your own system manual.
- Drive size and clearance: Confirm the supported M.2 length and whether a heatsink will fit. Check for shared lanes or ports and any slot-population rules in the manual.
- PCIe generation: A newer-generation drive may work in a compatible older-generation system, but it runs within the system’s limits. Crucial notes that PCIe generations are backward compatible; a Gen5 drive in a Gen4 system will not deliver Gen5 performance. See Crucial’s M.2 installation guide.
- RAM type and limits: Check whether the system uses DDR4 or DDR5, full-size DIMMs or laptop SO-DIMMs, its supported speed and maximum capacity, and whether any memory is soldered. Follow the prescribed module order and slot layout.
Crucial provides memory and SSD compatibility selectors, but the expected performance impact depends on the original computer’s capabilities and the upgrade selected. Without your model information, an exact RAM kit, drive length, capacity or PCIe generation cannot be specified responsibly.
Prepare the computer and protect your data
Back up important files before changing storage. If you plan to move Windows to the new drive, create recovery or installation media and decide whether you will clone the existing boot drive or install Windows afresh. Gather the correct screwdriver and, if needed, an M.2 screw; use sensible electrostatic-discharge precautions. Crucial also recommends consulting the owner’s manual and backing up files before installation.

- Shut down the computer fully and disconnect AC power.
- For a laptop with a removable battery, remove it. Follow the manufacturer’s service instructions to open the chassis; do not force a cover or connector.
- Reduce static risk by working on a suitable surface and using an anti-static wrist strap if available. Handle components by their edges and avoid touching contacts.
Install the NVMe M.2 drive
- Locate the confirmed NVMe-capable M.2 slot and check that its mounting point matches the drive’s length.
- Remove the retaining screw or heatsink as directed by the manual.
- Align the drive’s notch with the socket and insert it gently at roughly a 30-degree angle. Do not force it or touch its gold connector pins.
- Press the free end down and secure it with the correct M.2 screw. Tighten only enough to hold the module in place; reinstall a heatsink if the system specifies one.
- Reassemble the computer, reconnect power, and enter firmware setup to confirm the drive is detected.
After starting the operating system, a new secondary drive may need to be initialized and formatted before it appears for ordinary use. If you are cloning, select the new drive as the boot device after the clone is complete. Some motherboards share resources between M.2 sockets and SATA ports; an existing SATA drive may disappear when an NVMe drive is installed. Check the motherboard manual’s lane-sharing table if that happens.
Choose and replace RAM
Use the computer or motherboard manual, or a compatibility selector, to verify the memory standard and module type before ordering. A desktop DIMM and laptop SO-DIMM are not interchangeable, and DDR generations are not interchangeable. Prefer a matched kit when adding modules, and use the manufacturer’s recommended slots for the number of modules installed.
Rank #2
- Ideal for high speed, low power storage
- Gen 4x4 NVMe PCle performance
- Up to 6,000MB/s read, 4,000MB/s write
- Includes Acronis cloning software
- 5-year limited warranty
- With the computer powered down and disconnected as above, open the memory access area according to the service manual.
- If replacing a module, release its retaining clips and remove it by its edges. Align the notch on the new module with the slot; it fits only in the correct orientation.
- Press the module firmly and evenly until it is seated and the latches engage. For paired modules, use the board’s recommended slots.
- Close the chassis, reconnect power, and check firmware setup for the expected memory capacity. Then confirm the operating system reports the installed memory.
Clone Windows or use the NVMe drive as extra storage
If you want the NVMe drive to replace the current Windows boot drive, cloning can preserve the existing installation, but back up files and prepare recovery media first. The cloning procedure depends on the software and hardware involved; the key hardware check is that the new drive is detected and can be selected as the boot device afterward. If you only want extra storage, leave the existing boot drive in place and initialize and format the new drive in the operating system.
If connecting the NVMe drive externally for cloning or temporary transfer, use an enclosure that supports NVMe protocol conversion and provides adequate power. Intel says USB 2.0 is unsuitable for this purpose; USB 3.0 or Thunderbolt is appropriate. A generic M.2 enclosure may support SATA M.2 rather than NVMe, so verify the enclosure protocol before connecting the drive. See Intel’s NVMe enclosure guidance.

Troubleshoot a drive or memory upgrade that is not detected
- NVMe drive absent in firmware: Recheck that the slot supports PCIe NVMe, the drive is fully seated, and its length is supported. Review firmware settings and the manual’s lane-sharing rules.
- Existing SATA drive disappears: Check whether the occupied M.2 slot disables or shares a SATA port, then move the SATA connection to a supported port if the manual allows it.
- External NVMe drive not recognized: Confirm the enclosure supports NVMe rather than SATA M.2 and uses a suitable USB 3.0-or-better or Thunderbolt connection.
- RAM capacity is wrong or the computer will not start: Power down, reseat the modules, verify DDR generation and form factor, and check that each module is in the recommended slot. Consult the manual for capacity and supported-speed limits.
- Upgrade works but seems slower than expected: Check the system’s PCIe generation and memory speed limits. A compatible component may operate at the system’s supported speed rather than its advertised maximum.
Windows 11 requirements are not upgrade recommendations
Microsoft lists 4 GB of memory and 64 GB of storage as minimum Windows 11 requirements and directs users to their device manufacturer for upgrade options: Windows 11 specifications. Those minimum eligibility figures do not establish an appropriate memory or storage amount for a particular workload.
