Great! The order arrived in 40 days in mexico.The chip has its welds already installed is only a question of replacing it.Seller recommended. 10-10.As a fact, for those who don't know if the chip is in good shape is just a question of measuring the capacitors that are the silicon side, without measuring those with the multimeter they yield equal values on both sides s would mean that it is in short.In my case it was in short and the color change in silicon.It is also necessary to reprogram the bios as the pch is different from the original.
