mm grid. While the socket is called "1331," not every position is occupied by a functional pin. The layout is designed to handle high power delivery, high-speed data for PCIe lanes, and memory communication. 1331 pins. Mounting Type: Zero Insertion Force (ZIF). Dimensions: mm (approximate outer housing). Memory Support: DDR4 (Dual-channel). Functional Zones of the Pinout
On the physical CPU, this is marked by a small golden triangle.
Pins are typically indexed using a coordinate system (Rows and Columns), similar to a spreadsheet (e.g., Row A through Row AZ, Column 1 through Column 40). Common Repair Scenarios
