You can see how our mirror finish looks like in above video. Mac Pro 2009 4,1 (to 5,1) Delidded CPU Install Guide (x5680 x5690 12-core CPU Upgrade). Video will open in a new window. Only intended for Mac Pro 2009 dual CPU model.

Need upgrade to 5,1 firmware before install. Note that different from many sellers, this product has CPU die like a mirror.

No residues of solder, thus much better thermal conduction. Or testing we used pencil eraser and then used 90% alcohol to clean the pin contacts before install. Just in case it cannot boot for you, the first thing I'd try is to clean them again. Any questions about installing it are very welcome.
