Crucial (Micron) CT48G56C46S5
A specific DDR5 laptop memory module identified by manufacturer part number CT48G56C46S5. The stated 48 GB capacity, speed, latency, nominal voltage, and module format describe this SKU; check the specimen label and SPD for revision-specific details.
EXACT SKU: Crucial (Micron) CT48G56C46S5. Specifications identify the listed product family. Confirm the printed part number, revision/date code, SPD tables, and module markings on the specimen before service; memory vendors may change component sourcing across revisions.
Model specifications
| Manufacturer / SKU | Crucial (Micron) CT48G56C46S5 |
|---|---|
| Module class | Unbuffered, non-ECC notebook module; 262-pin SO-DIMM |
| Capacity / data rate | 48 GB; DDR5-5600 (5600 MT/s) |
| CAS latency / voltage | CL46; nominal module voltage 1.1 V. Profile or host selection may alter the operating data rate/timings. |
| Organization / ECC status | Non-ECC, unbuffered module with DDR5 on-die ECC; this is not system-level ECC. Check module revision and SPD for organization. DDR5 on-die ECC is not equivalent to host-visible ECC. |
| Form factor / generation | 262-pin SO-DIMM, DDR5; DDR generation notches and signaling are incompatible across generations. |
| Host platform limitations | 48 GB SO-DIMM support is platform- and BIOS-specific. Confirm support for the capacity and DRAM density in the notebook service documentation; older DDR5 hosts may not boot or may run at a lower rate. Requires a DDR5 SO-DIMM slot and a host memory controller/firmware supporting 48 GB per module and its device organization. 48 GB SO-DIMM support is platform- and BIOS-specific. Confirm support for the capacity and DRAM density in the notebook service documentation; older DDR5 hosts may not boot or may run at a lower rate. |
Compatibility & service notes
- Requires a DDR5 SO-DIMM slot and a host memory controller/firmware supporting 48 GB per module and its device organization. 48 GB SO-DIMM support is platform- and BIOS-specific. Confirm support for the capacity and DRAM density in the notebook service documentation; older DDR5 hosts may not boot or may run at a lower rate.
- Not compatible with a socket for another DDR generation: DDR5 pin count and keying do not make it interchangeable with DDR3, DDR4, or DDR5 modules of another generation.
- DDR5 on-die ECC is not equivalent to host-visible ECC. This module is unbuffered and is not a registered or load-reduced server DIMM.
- Follow the notebook service manual for power-down, battery isolation, and ESD procedures. Handle by the edges, align the notch, and never force the module into the slot.
- Before ordering a second module, confirm the exact platform maximum per slot, permitted ranks/densities, supported channel configuration, BIOS version, and qualified-memory guidance; mixed modules may operate at the slowest common settings or fail memory training.
Preservation record
Photograph the complete label and notch, preserve manufacturer part number and revision, retain an SPD dump when available, and record the host model, CPU, BIOS version, slot/channel position, reported operating data rate, and memory-test result.
