Identity & purchasing scope

This record identifies M393A4K40DB2-CVFBQ in the Samsung memory catalog. Its classification is manufacturer model. Preserve the full identifier when comparing offers: suffixes, revisions and assembly contents are part of the purchasing question.

Identify this Samsung memory module by the complete published reference M393A4K40DB2-CVFBQ. The recorded capacity is 32GB. The source places it in the DDR4 RDIMM product group. Review the source-backed observations and any host-specific notes before preparing an ASTER RACKIT enquiry. A qualified-vendor-list entry applies to its named test platform and conditions. It does not establish universal replacement compatibility or the configuration of an offered unit. Ask for confirmation of the label, revision, condition, availability and current-unit photographs. Use the technical record to prepare an inquiry rather than as evidence that an item is available, tested, licensed or covered by a particular warranty. Inherited fast-shipping and stock language is not carried into this catalog's commercial fields.

Recorded technical specifications

Each field states its evidence status. Inherited and title-derived values remain unverified; reviewed OEM facts do not certify an offered configuration.

Configuration & purchase checks

Confirm the complete module number, capacity, DDR generation, buffer type and organization instead of matching capacity alone.
Use the platform population rules. The speed printed on a DIMM is not a promise of operating speed in every processor and slot combination.
List the modules already installed and the modules being added. Existing parts are part of the compatibility question, not an afterthought.
Confirm processor count, accessible slots and a growth target. A logical slot-count picture is not the OEM physical installation sequence.
Ask for module labels and a memory-test record that identifies the tested system and population.

Adding an item prepares a local RFQ line. It does not create a price offer, reserve inventory or submit an order.

Platform relationships & upgrade review

No explicit target-platform relationship is provided for this record. Brand, socket, capacity and visual resemblance alone must not be used to invent a compatibility claim.

Related records below are category neighbors. They are not approved replacement parts.

Actual-unit evidence to request

Module labels

Connector and PCB condition

Protective packaging

Installed population list

Test scope

No server boot-screen image is attached to this record. Request product photographs and any diagnostic or entitlement record as separate evidence.

At acceptance, compare the delivered unit, labels and accessories with the approved list. Retain source revisions and receiving records for later maintenance.

Source trace & documentation

Remaining review: current offered condition · current stock · actual label and revision · exact model photograph approval · original component-maker packaged ordering SKU · universal system compatibility · manufacturer maximum memory rate unless independently documented

Frequently asked questions

Is the item currently available?

This is not a live stock feed. Confirm full identifier, condition, quantity, price and delivery scope in a written quotation.

Does this record certify compatibility?

No. Inherited fields and platform associations require review against the exact destination system and current manufacturer documentation.

What should I send in an RFQ?

Include the full identifier, quantity, destination, target platform, condition, accessories and evidence needed for acceptance.

Is a configuration number another server model?

No. Models, ordering configurations, options and reference labels are distinct record types. Ask which actual purchasing unit will be supplied.
