Clarification on "21 B6 E1 E2" The sequence "21 B6 E1 E2" does not correspond to a standard Intel Board Model number (e.g., DQ67OW, DH67BL). Instead, in the context of Intel Desktop Boards, this sequence typically refers to the Board Asset Tag or Board Serial Number found within the BIOS or on a physical sticker.
These identifiers are unique to specific units and indicate:
Since these codes are unit-specific identifiers rather than a model number, there is no single public "specification paper" titled "21 B6 E1 E2." However, I can provide a comprehensive technical brief (paper) regarding the system these identifiers are most commonly associated with.
Most Likely Association: This specific asset tag format is frequently found on Intel Desktop Boards based on the H67 or B65 Chipset (such as the DH67BL, DH67CF, or DB65AL), which were manufactured around 2021 (or use a legacy numbering scheme tracked by Intel's anti-counterfeit measures).
Below is a technical specification brief regarding the likely hardware associated with your board.
| Slot | Type | Electrical Lane | Physical Connector | | --- | --- | --- | --- | | PCIe x16 | 2.0 | x16 | x16 | | PCIe x4 | 2.0 | x4 (from chipset) | x16 (open-ended) | | PCIe x1 | 2.0 | x1 | x1 | | PCI | 2.2 | 32-bit | 2 slots | | PCIe Mini Card | 2.0 | x1 | Half-length (for WiFi) |
If you want, I can draft a shorter forum post, a classified ad, or a detailed teardown guide for one of these exact board revisions.
