Intel Ophir 82571 Dual Port Gigabit Ethernet Controller Die Shot

This is an Intel HL82571EB dual port Ethernet controller from a Sun Fire X4150 server. This uses 90nm lithography and was released in 2005. This chip only supports two 1 gigabit Ethernet ports, but the board has 4. It turns out the IO controller hub (another chip on the board) can also handle an additional pair of Ethernet ports on it's own. This chip was hidden under the small heat sink on the right side of the main board.

 

Stitching this chip was a nightmare on the normal software I use and this was the final straw for me to finally buy a PTGui license. It handled it much better than the other tools I've used previously.

 

Prepared by shaving away the metal layers using utility razor blades and washing away removed metal with water to prevent scratches.
