Crucial CT16G56C46S5
Specific Crucial DDR5 laptop SO-DIMM. This is a named manufacturer product or kit, not a general DDR standard overview. Specifications below are limited to information published for the model.
MODEL ID: Crucial CT16G56C46S5. Confirm the full model number, suffix, revision and SPD against the actual specimen before relying on compatibility or timing claims.
Model specifications
| Manufacturer / product | Crucial CT16G56C46S5 |
|---|---|
| Product class | Specific Crucial DDR5 laptop SO-DIMM |
| Source-backed configuration | 16 GB DDR5-5600, 262-pin SO-DIMM; CL46; 1.1 V per Crucial product page. Rank and ECC/buffering details are not presumed beyond manufacturer listing. |
| Platform compatibility | Requires a DDR5 SO-DIMM platform supporting 16 GB modules. It is not a replacement for DDR4 SO-DIMM; actual speed depends on the system controller and supported timing. |
| Variant boundaries | Only values cited for this exact SKU are stated. Unlisted timings, ranks, organization, or sub-revision differences must be checked against the specimen label, SPD and manufacturer data. |
Compatibility & service notes
- Requires a DDR5 SO-DIMM platform supporting 16 GB modules. It is not a replacement for DDR4 SO-DIMM; actual speed depends on the system controller and supported timing.
- Power down before removal, use ESD precautions, handle by the edges, and never force a memory module into a keyed socket.
- Identify ECC and buffering independently: ECC UDIMM, RDIMM, and LRDIMM have distinct platform support requirements. DDR5 on-die ECC is not system-level ECC.
- Check CPU/controller support, motherboard or server service manual, firmware, module capacity/density, slot population and supported data rate. Physical fit is not proof of compatibility.
Archival record fields
Check the exact module revision/SPD and system vendor maximum capacity and JEDEC timings. Preserve both-side photos and the host service reference. Preserve label photographs, SPD data, full SKU, revision/date code, host configuration, BIOS/BMC version and test results. When installed, record slot and channel location.
Manufacturer & standards sources
- Crucial — CT16G56C46S5 product pageManufacturer source for the named product; use full part number and revision to verify the specimen.
- JEDEC — DDR5 SDRAM standardGeneration-level standards context; the product listing identifies the module-specific data.
Manufacturer pages are the model-specific source; JEDEC pages define generation-level context. For a preserved machine, its vendor manual and validated memory support list take precedence over generic fit claims.
