LGA 1200 CPU in LGA 1151 board (read the post)

ExalyThor · January 4, 2022

Has anybody tried to use intel's 10th and 11th gen on older motherboards? The different notch location on the socket won't stop any determined xocer and I'm curious if anybody actually tried an 10900k on a z170 motherboard for example.

Different pinouts. You'd fry the CPU.

Won't work. The 1151 is pin count on the CPUs, same with 1200. Physically different. Only way this may ever work is if someone made an adapter like LGA771 to LGA775. Then you would also need modded BIOS to support the chips. TONS of work for no return really so likely won't happen in this day and age.

The thing is, 771 to 775 was just covering up a couple pins and shorting one other IIRC. Unlike 1200 vs 1151 which would probably require a whole remap.

With 1151v1 and 1151v2, there were weird BIOS mods but that was around it. Not very common. With 1200 it would be difficult.

If there are enough spare 1151v2 boards I can see some Taobao sellers making weird adapters. I have a couple laptop to LGA1150 adapter boards mounted on laptop CPUs (bought off LMG in a clearance sale) but they're getting rare. Probably running out of random Haswell laptop CPUs... which is the problem with making these.
