What is the difference between an LGA 1151-2 socket and a LGA 1151 socket

 

[jojesa]

LGA 1151 (100/200 series) is used for 7th and previous generations Intel CPUs.

LGA 1151-2 (300 series) is used for 8th and 9th generation Intel CPUs.

Yes it will work. All 8xxx work on Z370. Some 9xxx if you update the bios.

ok thanks

The difference is in the pins themselves. While they have the same amount, the 2 sockets are aligned very differently, where ram, ground, power, pcie etc all line up. Intel should have just added a redundant pin and called it lga1152 instead.

or made the socket physically incompatible. Though modders have gotten 8XXX working on Z270, so really intel just want to screw people over.

 

[Karadjgne]

Heh, 'working' is subjective. They get past bios and can do simple stuff in windows, but have yet to get full functionality and stability as the ram/mc issues are throwing a fit.

Yeah, lga1152 would be physically incompatible. All in the name of saving a buck on some re-tool and die.

Right.....oh Intel...
