Intel Desktop Board 21 B6 E1 E2 Specification Exclusive //free\\ Now
The identifier 21 B6 E1 E2 (often seen as /21-b6-e1-e2 ) is not a specific Intel motherboard model number, but rather regulatory or industry specification marking found on several legacy Intel desktop boards
. While these markings are often mistaken for the model name, they typically appear on boards from the Sandy Bridge (2nd Gen) Ivy Bridge (3rd Gen) Core Technical Specifications
Based on common board configurations bearing these regulatory marks (such as those using the LGA 1155 socket), the general specifications are as follows: Socket Type:
LGA 1155 (Socket H2), supporting 2nd and 3rd Generation Intel Core i3, i5, and i7 processors.
Typically compatible with Intel 6-series or 7-series chipsets (e.g., Q67, H61, B75). DDR3 SDRAM
via dual-channel slots, often limited to 1333/1600 MHz depending on the specific model and CPU. Expansion Slots: Usually includes at least one PCI Express 2.0/3.0 x16 slot for dedicated graphics. I/O Ports: intel desktop board 21 b6 e1 e2 specification exclusive
Standard configurations include Ethernet (RJ-45), USB 2.0, and sometimes USB 3.0, along with VGA/DVI or HDMI for integrated graphics. How to Identify Your Exact Model
Because "21 B6 E1 E2" is a general marking, you must look for the AA (Altered Assembly) number to find the specific manual and drivers. Locate the AA Number:
Look for a small barcode label on the board with a number like G23116-XXX System Information: If the board is functional, press the Windows Key , type "System Information," and look for the BaseBoard Product field to see the true model name (e.g., DH61BE or DQ67SW).

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: The identifier 21 B6 E1 E2 (often seen
- Manufacturing Site: Where the board was produced (e.g., "E1" often corresponds to Intel's facility in Leixlip, Ireland; "E2" to another specific line or region).
- Year/Week: The "21" often denotes the year of manufacture.
- Batch/Lot: "B6" typically refers to the specific production lot.
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.
The "21 B6 E1 E2" Code: Decoding the Marking
First, a critical revelation: "21 B6 E1 E2" is not a single model number. It is a solder pad identifier or a PCB revision matrix code used on Intel’s LGA775 and early LGA1156 desktop boards produced between 2008 and 2011.
- 21 B6: Refers to the PCB substrate lot and design rule version.
- E1 / E2: Indicates specific power delivery phases and I/O bridge revisions.
In plain terms, boards marked with 21 B6 E1 E2 belong to two primary families: the Intel G41 Express Chipset series and, more rarely, the DP45SG series. Exclusively, we have confirmed that this code appears on boards designed for Intel’s Wolfdale (Core 2 Duo) and Yorkfield (Core 2 Quad) processors. Manufacturing Site: Where the board was produced (e
