If you found this string printed directly on the board (silkscreen or sticker), it may be a , not the model name. Please re-check the board surface for an Intel logo and a model number starting with D , DG , DH , DP , DQ , or DX .
Depending on the specific board (e.g., D945GTP vs D946GZIS), these motherboards typically feature: Usually 2 or 4 DIMM slots.
When you first turn on a computer with an Intel Desktop Board, the system's Basic Input/Output System (BIOS) will display an identification string near the top-left corner of the screen. For example, on older boards, you might see a string like 1.00.12.CS1 , where CS1 is part of the identifier. This string is a reliable indicator of your board's model. If your computer boots to a splash screen, try pressing the Esc key during startup to bypass it and reveal the BIOS information. : USB 2
: High-quality audio capacitors, sometimes with 7.1 surround sound.
In short, you're looking at a question posed by a user who has likely seen this mix of regulatory codes and BIOS strings on their screen and is trying to identify their motherboard. The good news is that solving this mystery is a straightforward process.
The phrase is critical. In Intel’s internal classification:
LGA775 is an excellent platform for building a high-performance Windows XP gaming machine.
Compatible with older versions of Windows (Windows 7/XP) for legacy software.
