Identity & purchasing scope
This record identifies 661128-B21 in the HP processors catalog. Its classification is supplier reference. Preserve the full identifier when comparing offers: suffixes, revisions and assembly contents are part of the purchasing question.
HP 661128-B21 is an observed supplier own-card reference grouped as oem processor option. Use every character of the complete reference in your enquiry. Keep the OEM option owner distinct from any Intel or AMD name in the source title. Confirm socket, supported host revision and the included heatsink or installation items. The retained supplier observation supports reference and object classification only. Manufacturer ordering status, physical maker, technical parameters, lifecycle, availability and actual-unit condition remain unverified. 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.
Specifications pending review
No additional technical table was supplied for this identity. Request the current datasheet and item labels rather than guessing specifications from a title.
Supplier own reference and remaining checks
Observed supplier reference owner: HP
Complete observed reference: 661128-B21
Own product group: OEM processor option
The dated supplier category card documents the complete reference and own object grouping. A separate product-detail page was not fetched for this observation.
This is one OEM processor option or kit reference. An Intel or AMD name in the source title does not replace the OEM option owner or verify the supplied kit contents.
Manufacturer ordering status, technical parameters, compatibility, lifecycle, included items and supplied-unit condition remain unverified.
Source evidence does not establish stock, price, warranty, authorization, a physical design count or an actual-unit photograph.

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.

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.

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.
