Kingston FURY KF556S40IB-32
A specific DDR5 laptop memory module identified by manufacturer part number KF556S40IB-32. The stated 32 GB capacity, speed, latency, nominal voltage, and module format describe this SKU; check the specimen label and SPD for revision-specific details.
EXACT SKU: Kingston FURY KF556S40IB-32. 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 | Kingston FURY KF556S40IB-32 |
|---|---|
| Module class | Unbuffered, non-ECC notebook module; 262-pin SO-DIMM |
| Capacity / data rate | 32 GB; DDR5-5600 (5600 MT/s) |
| CAS latency / voltage | CL40-40-40; 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; verify rank and organization against the label, SPD, and revision documentation. 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 | Requires a DDR5 host supporting a 32 GB SO-DIMM and the module organization. The XMP 3.0 5600 MT/s timing profile may not be available on every notebook; firmware can downclock it. Requires a DDR5 SO-DIMM slot and a host memory controller/firmware supporting 32 GB per module and its device organization. Requires a DDR5 host supporting a 32 GB SO-DIMM and the module organization. The XMP 3.0 5600 MT/s timing profile may not be available on every notebook; firmware can downclock it. |
Compatibility & service notes
- Requires a DDR5 SO-DIMM slot and a host memory controller/firmware supporting 32 GB per module and its device organization. Requires a DDR5 host supporting a 32 GB SO-DIMM and the module organization. The XMP 3.0 5600 MT/s timing profile may not be available on every notebook; firmware can downclock it.
- 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.
