An Analysis of the Z390 Socket Proves the Extra Pins Aren't Necessary

Der8auer on YouTube (Roman Hartung) has performed an in-depth analysis of the Z390 socket where he physically extracted the pins from a dead Z370 board and measured how much of an load each pin can take. After applying up to 5 amperes of power to the pin, he concluded that it can easily withstand the rigors of a daily 1.01 amperes load. Then he taped off 18 pins on an i9-9900K to simulate it running in a Z270 motherboard. This increased the load on each pin, but no adverse changes were observed in the socket or the board. He then taped off varying amounts of pins and tested the i9-9900K with up to 69 pins taped off which created a 1.92 ampere per pin load. Again, no changes were observed during testing that exceeded 6 hours. The conclusion is that the LGA-1151v2 is absolutely unnecessary.

Roman Hartung has proven very clearly that the LGA-1151v2 socket is basically completely unnecessary. The pins withstand even a very limited power supply without any problems, there is no damage to the mainboard, the socket or the processor. This also proves once more that Intel probably didn't allow compatibility with the old motherboards for sales reasons.
