The marking (often preceded by a slash, as in /21-B6-E1-E2 ) is a regulatory and industry specification marking found on several vintage Intel desktop boards, most commonly those using the LGA 1155 socket and supporting 2nd Generation Intel Core (Sandy Bridge) processors . Key Identification Details
: Primarily supports 2nd Generation Intel Core i3, i5, and i7 processors (e.g., i5-2300, i7-2600). Memory : Typically features two or more DDR3 SDRAM slots.
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
Designed for data integrity, this board provides full RAID functionality (0, 1, 5, 10), allowing for data mirroring or striping across drives. D. Enhanced Security
If you have a physical board with these markings, refer to the DQ67SW specifications above. For exact identification, look for the (e.g., G20118-xxx) printed near the center of the board or on a white barcode sticker.

: Often includes 1 x PCI Express 2.0 x16 slot for dedicated graphics.
Keep in mind that the Intel Desktop Board D21-B6-E1/E2 is an older motherboard model, and its availability and support might be limited. However, it remains a great option for users looking for a reliable and affordable motherboard solution.
: Includes standard connections like Ethernet (RJ-45), USB 2.0, and sometimes USB 3.0. OS Support via dual-channel slots, often limited to 1333/1600 MHz
When this specific string appears on consumer-grade legacy hardware, it matches the platform requirements of the LGA1155 socket ecosystem. Below is the architecture configuration breakdown: Processor & Socket Support : LGA1155 (Socket H2).
. 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
