Intel Desktop Board 21 B6 E1 E2 Specification Link 90%
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
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.
