Scope
This Family captures ECC memory requirements that need system-level confirmation. ECC alone is not a complete module specification.
Request preparation
Share the system, CPU or motherboard context, module architecture, capacity, speed, rank, current population, quantity, and substitution rules.
Technical parameters and selection boundaries
Published configurations differ by manufacturer and exact part number. These are selection dimensions, not one combined specification.
| Parameter | Documented example or choice | Verify for this request |
|---|---|---|
| Capacity and organization example | Kingston KSM56E46BD8KM-32HA: 32 GB, 2Rx8, 288-pin DDR5 ECC DIMM. | Exact-part example. Rank, component organization and module class must match the platform; equal capacity is not sufficient. |
| Data rate and programmed timing | DDR5-5600; SPD timing 46-45-45 at 1.1 V for this part. | MT/s is a transfer rate. Actual platform settings and supported population may differ; do not promise this speed in every server. |
| Supply rails | VDD and VDDQ: 1.1 V typical; VPP: 1.8 V typical; VDDSPD: 1.8–2.0 V. | These are separate electrical rails in the named datasheet, not interchangeable voltage options. |
| ECC organization | x72 ECC, arranged as two independent x36 I/O subchannels in the named module. | Confirm system-level ECC support and the exact module type. A DDR5 label alone is not enough to select a replacement. |
| Mechanical height | PCB height: 31.25 mm (1.23 inches). | PCB height is not a universal clearance envelope; check the full drawing, slot latch and airflow area. |
| Temperature limits | Operating: 0 to +95 °C; storage: −55 to +100 °C for this documented part. | Module limits are not server-room ambient ratings. Follow the platform thermal requirements. |
| Registered versus unbuffered memory | RDIMM includes a register; UDIMM connects without that register. | Use only the class specified by the CPU and board. RDIMM is not a drop-in substitute for a UDIMM-only system. |
Standard configurations and project options
| Configuration area | Documented option | Project decision |
|---|---|---|
| Replacement specification | Match complete MPN, capacity, rank, organization and programmed speed before approving an alternative. | Changing capacity or speed is a new selection, not a custom modification to a finished DIMM. |
| Component and revision control | The inspected document identifies Hynix A-die and revision A, dated 31 May 2023. | Request the current datasheet and PCN history for the supplied lot. Do not treat this historical revision as a stock claim. |
| Platform information for quotation | Provide server or motherboard model, CPU, existing module label and intended DIMM population. | ECC, registered/unbuffered class and system support must be checked together; no generic compatibility guarantee. |
Representative models and configurations
Examples illustrate real product variation. A listed manufacturer or model is not a statement of our stock, authorization, or confirmed availability.
| Manufacturer / series | Published configuration | Important scope |
|---|---|---|
| Kingston KSM56E46BD8KM-32HA | 32 GB; DDR5-5600 CL46; 2Rx8; 288-pin; x72 ECC; 1.1 V VDD typical. | Representative exact MPN from revision A of document 4810951A. Confirm current lifecycle, revision and system qualification before ordering. |
Applications and procurement context
- For an ECC memory replacement or capacity change, start with the installed platform and complete module identity. Verify memory class and supported population before comparing price or accepting an alternative.
Compatibility, current supply, lead time, origin, and acceptance documents must be confirmed for the actual order.
