Identity & purchasing scope
This record identifies 638871-B21 in the HP processors catalog. Its classification is oem option part number. Preserve the full identifier when comparing offers: suffixes, revisions and assembly contents are part of the purchasing question.
HP 638871-B21 is a processor kit named in the SL390s G7 ordering table. Keep this complete HP code in your ASTER RACKIT enquiry. Review the included components and intended system before ordering. 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
- Keep the model suffix and ordering code. A CPU model, tray code and OEM upgrade kit can describe different purchasing units.
- Check the server generation, firmware and thermal support. A matching socket does not by itself prove compatibility.
- For a multi-socket system, verify pairing requirements and include the correct heatsinks and carriers in the same review.
- Record whether the offer is production silicon, an engineering sample or a qualification sample. Do not infer its status from the model name.
- Request top-side markings, package photographs and the stated test scope before accepting a substitution.
Adding an item prepares a local RFQ line. It does not create a price offer, reserve inventory or submit an order.
Read the category procurement guide →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
01
Top-side markings
02
Package underside where safe
03
Carrier or protective tray
04
Heatsink if included
05
Production or sample status
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.

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.
