7th Gen Core "Kaby Lake" Won't Work on 300-series Chipset Motherboards

The upcoming Intel 300-series chipset, and LGA1151 socket continues to be a source of chaos for PC builders. While the 100-series and 200-series chipset based motherboards support both 6th generation Core "Skylake," and 7th generation Core "Kaby Lake" processors, they will not support the upcoming 8th generation Core "Coffee Lake" chips. What's more, the upcoming 300-series chipset motherboards, which were earlier believed to feature backwards-compatibility for "Skylake" and "Kaby Lake" chips, will not support them, according to a Hardware.info report.

The LGA1151 socket between the two platforms remains unchanged, down to the package notches, which are designed to prevent you from installing a processor on an incompatible motherboard (eg: LGA1150 processors on LGA1151 motherboards). This isn't even a case like the incompatibility between LGA2011 and LGA2011v3, where the latter features DDR4 memory I/O, compared to the former's DDR3. Platform segmentation, and synthetically keeping up with a product development cycle, by forcing people to upgrade motherboards every two generations, appears to be Intel's primary motivation. The Hardware.info report, however, doesn't rule out the possibility of 300-series chipset motherboards getting support for older LGA1151 processors in the future, through BIOS updates.

The Von MatricesWe would be hearing the exact same complaints if there was a new socket incompatible with older processors. Every 2 generations, Intel makes the socket electrically incompatible with older CPU; that's nothing new. This time, they just aren't changing the number of pins, but that hardly makes a difference.

The number of pins on a socket has nothing to do with electrical compatibility. It's expensive to create a new socket just to have one more or less pin. I can't imagine how much money is saved by the motherboard makers and Intel by only having to stock one type of socket as opposed to having to convert production processes to use another. AMD did the same thing by using the same socket for Threadripper and EPYC.

And having chipsets that don't support older CPUs despite having the same socket is nothing new. Many LGA775 Core 2 motherboards did not support older Pentium 4s in the same socket. Even 15 years ago, socket 478 boards dropped support for earlier FSB400 CPUs despite using the same socket.
And how much difference do you think there is between creating a "still 1151 socket but electricaly different" and a "one more 'dummy' pin then the old 1151 socket"? Don't both cases require a new socket anyway?

TheinsanegamerNSo intelligent that you decided, for some reason, that intel WOULDNT change sockets after 2 CPUs, like they have been doing since 2009? :laugh:

You also thought that coffee lake would be such a major improvement, unlike ivy bridge, haswell, broadwell, skylake, and kaby lake, that you bought a tin-plated pentium to go with this $1500 machine rather then just buying the good chip now :roll:

And, despite thinking AMD's newest platform is great, you bought an intel platform anyway, then complain when intel bends you over the barrel?o_O:slap:

Yeah, good job there bud. Intel doesn't give 2 #$%$s! because consumers like you will blindly buy their stuff.
Just thought this 'ol elephant would drop back into say:

I told you so.

Mocking people is rarely a good idea. It might come back. Some call it karma. Others just hate it when others are right.

Intelligent enough to get by and eventually be right, it seems. Even as predicted. Remember, I upgraded from - I don't recall - to the best at the time, hoping I could maybe get an i7, if or when something could compete with the i7-7700k. I am back at tertiary studies and don't have excess cash. Necessity is the mother of invention.

I am now deciding which LP 4-core Coffee Lake I will install on my Asrock Z270 Fatality ITX. From a Pentium 4560.

Peace. *Elephant call*

Edit: So emote. Grammar etc.

Lol did that get reported....? Spare me.

Edit: Yup. It did. Seems it was not reportable.
