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.

Somehow I already assumed this. I guess this makes it official though.

Official? Official rumor maybe. ;)

Is that even news that new Intel CPU will need new motherboards?

...it is the same repackaged core, on the SAME SOCKET. Same RAM - almost same EVERYTHING.

This is the biggest middle finger to the average consumer that Intel could possibly make.

They are showing that despite AMD's new offerings and competition, Intel doesn't give 2 #$%$s!. It is almost CERTAIN that Intel could support Coffee Lake on Z270 if they so desired, without much effort. Instead, they would rather make money and hide behind the IDEA that they used to force consumers to upgrade, because of significant advances in technology.

I suggest the 'average consumer' should vote with their money. If you need a new motherboard to upgrade to a CPU REPACKAGE (despite it being on the identical socket - an unprecedented move) - then move across to an AMD platform when you do. Their Threadripper processors are brilliant AND value-for-money.

To Intel: Go. 2. Hell.

Edit: I spent $1500 upgrading a few months back, ensuring I had 32Gb DDR4 3866mhz, Thunderbolt 3 and the latest Intel chipset in anticipation of their re-re-release of their 14nm line in more than just a quad-core configuration (2007 says Hello, Intel). In the meantime I grabbed a G4560. Seems Intel has arbitrarily shafted me and short-circuited my otherwise intelligent purchasing decision. May AMD bring it to them.

Yours Sincerely,

Psinet

i cannot help bot wonder what the hell is intel thinking? they should just come out and say what they are going to do. whatever processors are going to be supported on what platforms or not, having rumors flying around cannot be the best approach, can it?

It is entirely possible that the additional cores means that Intel had to assign additional pads to pins that weren't used in previous chipsets and this is causing the issue.

However, this should at least have been done so the 300 series chipset was backwards compatible with the 6000 and 7000 series CPUs, if it really is the case.

Might not be that simple, I have a very strong hunch that number of total lanes will increase along with core count.

Its to expensive for these times RAM 16GB 140 euro, motherboard 150-200, CPU 150-200 I suppose will keep playing and finding games like Left 4 Dead 2, Life is Strange and similar games who do not require 10 times faster CPU and who works on new erx card.

Why not? Intel always use to change sockets, often for no particular reason other than just.. replacing the whole system. People seem to be ok with that policy since they buy intel products!!!!!!!! They seem to like it. Now they can even make incompatible processors for the SAME socket. I bet people will still buy them. The sheeps love intel. Intel love the sheeps. What a great relationship.

P.S. And yes, i am buying only AMD cpus since 1998.

This is exactly the same story as Haswell and Broadwell

Not really. At least Z97 supports all existing LGA1150 CPUs.

Anyway we will just have to wait to find out if Z370 indeed drops support for sky and kaby.

Uhm is this google translate accurate?
For this quicktest we got started with an Intel Z370 motherboard and a Kaby Lake processor. We used an affordable Celeron G3930 processor to minimize damage to any accidents. The CPU turned out to be without problems: physically, the "new" socket 1151 is identical to the processor foot that we know. Once installed, we tried to boot the system. The motherboard went on and began his self-test but fell out during the last step (VGA) and started again. This was also the case with a single video card. Now, of course, this is just one Z370 motherboard, but we have no reason to believe that it would work with other boards.
To me it sounds like it might work with updated microcode. Maybe motherboard manufacturer just did not bother adding support for some low end cpu for their high end motherboard. Or maybe firmware ain't just ready yet for retail market. But if cpu would not be compatible I don't think it would even post that far.

Different voltage may be required as well. Incompatibility sucks whenever it happens, but we don't yet know the reasons this time.

True, but annoying if you already have a perfectly good Z87 motherboard (like I do) but needs to upgrade it to buy Broadwell

I'm not going to migrate to AMD unless they get their graphic division's crap together. Migration for me would be an all or nothing thing, I guess.

AMD CPU/NVIDIA GPU, what do AMD's gpu have to do with it or did I miss something and Intel got their graphic division's crap together when I was wasn't looking?

It has nothing to do with Intel.

I'm just saying I'd rather get both products from AMD if I switch. I like the whole package, but I'm not going to bother until it's all available at will.

So 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.

They change the soket a little, is LGA 1151 - V2 now. so no is fine.

You're not saying you'd rather get both products from AMD, you're saying you're not buying AMD till they can give you both a CPU and a GPU. Huge difference.

The real sarcastic question would be: Is it even news that an old Intel CPU doesn't need a new motherboard?

I guess this is at least discussion worthy but take a deep breath folks. Who gives a flying fart about forcing a Kaby processor into a Z370 motherboard?

I don't even understand the difference. Or why anyone's that interested in when and how I purchase something.

It's so pointless I don't even want to explain. It's just my OCD, if you will. My gravitation to having some neatness in having two big parts from the same brand.

Why anyone gets confrontational about that, I don't know. The fact that I even consider it should make an AMD fan happy... but apparently that's not good enough. It's "come to us right now or you're just a damn sheep". This is insanity.

Well you could ask that question from Sandy/Ivy bridge owner with dying lga1155 motherboard... Cpus usually last longer than motherboards just saying.

No it's not insanity, it's called a double standard. The things is the way you are talking right now means you are using an Intel CPU other brand GPU, most likely an Nvidia GPU. So if you were to dump Intel and go AMD nothing would change in this aspect but you want to be all irrational about it and claim CPU/GPU have to be both from the same camp when it comes to AMD. Pardon, but people are just pointing out that you aren't making any sense.

It makes sense, he's free to buy whatever he wants. I was just pointing out he's limiting his options for no apparent reason.
