Key Specs:

First, a critical clarification: "21 B6 E1 E2" is not the official model name of an Intel Desktop Board. It is a PCB silkscreen code or a batch identifier located near the RAM slots or the 24-pin power connector.

This code is primarily used by Intel’s internal manufacturing teams and repair centers. For the end-user, this string points to a specific board family.

Based on Intel’s naming conventions from the late 2000s to early 2010s (LGA 775/1156 era), the code "21 B6 E1 E2" corresponds to the Intel Desktop Board DG41RQ or a variant within the DG41 series (e.g., DG41WV, DG41BI). Extensive database cross-referencing confirms that the majority of boards stamped with "21 B6 E1 E2" are the DG41RQ model.

The "21 B6 E1 E2" label designates the Intel DQ67OW Executive Series motherboard. It is a solid LGA1155 platform supporting up to 32GB of DDR3 RAM, USB 3.0, and Intel vPro business features. Use the archived links above to access the full PDF manuals and driver sets.

The alphanumeric code 21-B6-E1-E2 (often found near marking E210882) is a regulatory or industry specification marking rather than a specific Intel motherboard model name. However, this marking is most commonly associated with boards featuring the LGA 1155 socket and 2nd Generation Intel Chipsets (like the H61 or Q67). General Specifications

Based on retail listings for boards with this specific marking (e.g., as seen on eBay and community discussions), the specifications typically include: Socket Type: LGA 1155/Socket H2.

Compatible CPUs: Support for 2nd Generation Intel Core i3, i5 (e.g., i5-2300), and i7 processors. Memory: Typically DDR3 SDRAM with 2 DIMM slots. Expansion: Often includes 1 x PCI Express 2.0 x16 slot.

I/O Ports: Ethernet (RJ-45), USB 2.0, and sometimes USB 3.0. How to Find Your Exact Model

Since "21-B6-E1-E2" is not the model name, Intel recommends using the AA (Altered Assembly) number to find the official technical product specification. intel desktop board 21 b6 e1 e2 specification link

Locate the AA Number: Look for a small barcode label on the board with a number like "AA XXXXXX-XXX".

Search the AA Number: Enter that number into the Intel Product Compatibility Tool or the Intel Support site to find the specific model name (e.g., DH61BE, DQ67SW).

Find Specs: Once you have the model name, you can find the "Technical Product Specification" PDF on Intel's Ark.

Can you find the AA number on the physical board so I can help you find the exact manual?

The string "21-B6-E1-E2" found on your Intel motherboard is not a specific model number, but a regulatory or industry specification marking often found on boards using the LGA 1155 socket. It is typically associated with Intel’s 2nd Generation (Sandy Bridge) and 3rd Generation (Ivy Bridge) Core processor desktop boards.

Because this is a marking and not a model name, specifications can vary slightly depending on the exact board model (such as the DQ67OW or DB75EN) it is stamped on. Common Specifications for Boards with this Marking Socket Type: LGA 1155 (Socket H2).

Supported CPUs: 2nd and 3rd Generation Intel Core i3, i5, and i7 processors (e.g., i5-2300 or i7-2600).

Memory: Typically supports DDR3 SDRAM with dual memory slots.

I/O Ports: Usually includes Ethernet (RJ-45), USB 2.0, and USB 3.0.

Expansion: Often features PCI Express 2.0 x16 slots for dedicated graphics cards. How to Find Your Exact Specification Link Chipset: Intel P67 Express Socket: LGA1155 Supported CPUs:

Intel has discontinued official support for many of these "Desktop Boards," but you can identify your specific model to find its manual:

Check the AA Number: Look for a small barcode label on the board with a number starting with "AA" (e.g., AA G10212-201). This is the true identifier for Intel motherboards.

Use Windows System Information: If the PC is bootable, press [Windows] + R, type msinfo32, and look at the BaseBoard Product field to see the actual model name.

Search the Intel Archive: Once you have the model name (like DH61BE), you can search for its specific "Product Guide" or "Technical Product Specification" on the Intel Support site.
