Crucial CT16G48C40U5
Specific Crucial DDR5 desktop UDIMM. 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 CT16G48C40U5. 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 CT16G48C40U5 |
|---|---|
| Product class | Specific Crucial DDR5 desktop UDIMM |
| Source-backed configuration | 16 GB DDR5-4800, 288-pin unbuffered non-ECC UDIMM; CL40; 1.1 V per Crucial product data. DDR5 on-die ECC is internal to DRAM and does not make this system-ECC memory. |
| Platform compatibility | Requires a DDR5 desktop platform supporting 16 GB modules at this device density. Incompatible with DDR4 slots; CPU and motherboard may set a lower speed. |
| 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 desktop platform supporting 16 GB modules at this device density. Incompatible with DDR4 slots; CPU and motherboard may set a lower speed.
- 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
Keep the full model label and SPD and distinguish on-die ECC from system-level ECC. Verify platform capacity support rather than relying on physical fit. 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 — CT16G48C40U5 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.
