01 / Check

Keep the part number intact

Use the manufacturer part number exactly as it appears on the requirement or existing module. It is more precise than a generic description such as “32GB server RAM” and gives the listing review a stable reference point.

TrustDIMM product pages display the P/N when it is published with the listing, together with the imported specifications available for that component.

Verification flow

Keep the exact part number connected to the required fields.

  1. 01

    Part number

    Copy it exactly from the requirement or existing module.

  2. 02

    Specification fields

    Compare generation, type, capacity, speed, rank, voltage, ECC, and form factor.

  3. 03

    Platform rule

    Confirm the candidate against the target platform documentation.

The flow highlights the information to preserve when comparing a listing. It does not certify compatibility or authenticity on its own.

02 / Check

Compare the module fields

For server memory, compare the manufacturer, capacity, memory generation, DIMM type, speed, rank, voltage, ECC, and form factor. A match should be assessed against the platform requirement, not inferred from a title or photograph.

RDIMM, LRDIMM, and UDIMM are listed separately because module type is part of the compatibility review. If any required field is unknown, use the platform documentation or request a sourcing review before ordering.

03 / Check

Use listing context before requesting

Condition / Grade information is shown at the listing level when provided. Read it with the specifications and availability information currently displayed on the product page.

When an exact P/N is not present, submit it with the required quantity and relevant platform context. A sourcing request is an availability review, not a stock reservation, quote, or compatibility guarantee.
