    The socket itself was 942 pins, yes, and AM3 had 941, so you'd assume, correctly, that a CPU with 942 pins (am3+ CPU) would not work (fit) inside an AM3 socket. Except, you're forgetting that the amount of pins a socket has, does not denote how many the CPU have

    AM3 socket = 941
    AM3 CPU = 938
    AM3+ socket = 942
    AM3+ CPU = 940

    And i quote:

    "Some manufacturers have brought AM3+ support to some of their AM3 motherboards via a simple BIOS upgrade. Mechanical compatibility has been confirmed and it is possible for AM3+ CPUs to fit in AM3 boards, provided they can supply enough peak current. Another issue is the use of the sideband temperature sensor interface for reading the temperature from the CPU. Therefore, some CPU PWM fan headers may only run at full speed. Also, certain power-saving features may not work, due to lack of support for rapid VCore switching."

    Funny the last time I adopted a an upgradeable chipset mindset...
    ( after my old dual socketed intel BX boards that could take anything )
    I actually bet on AMD with socket 939 and got but hurt pretty quickly! ;)

    But I have been praying that they force some innovation via a new chipset design with coffee lake!
    And after the 7740x lane nerf...
    I am hoping that flak from as much is enough of a mandate for a respectful Intel to cater the coffee lake core count increase with a lane count increase to compliment the excitement/energy of such additions! ( enthusiasm for enthusiasts )

    I am not holding my breath but a 6 core 12 thread coffee lake with around 30 lanes empowered/"forced" by a new chipset is all I need to salvage my sadly scar'd Intel love and adopt such a core/lane increase combination as my own "personal hedt" solution!
    ( finally replacing my aging 6 core i7-980x socket 1366/X58 solution that I have been refusing to upgrade during 7 years of "OBVIOUS" increment. )

    It could happen? :(
    ( let me have my illusions dammit! )
    Where if forcing a new chipset for coffee lakes equates to real value and technical advantage/advancement...
    Who am I to then "nay say" till the actual writing on the wall is revealed?

    My question is also about backward compatibility, but from the other point of view: will the new Z370 & Z390 motherboards support the current Skylake and Kaby Lake series?

    I find your understanding lacking. My last three PCs have been Intel based (I wonder what kind of an AMD fanboy that makes me). I was happy with the first two, but I'm disgusted with this current one, which is basically the same as the previous despite two whole CPU generations between them. Amazing 10% more power with exactly the same amount of cores. Not even the fricking HT was added.

    Here's a fact just for you: You can dislike Intel's decisions during the last half a dozen years without being a blind AMD fanboy.

    I'm sure that marvelous piece of information is of super hyper uber ultra huge consolation to those of us who bought new mobos last year or this very same year (Kaby Lake).

    Is there any word yet of actual date of availability....?
    Announcing the new toys is alright but when will it be available to actually buy...?

    And there I was hoping i5 8400 will be my new upgrade, but base clock too low. Probably I'll go for the i5 8600K with turbo enabled only when needed. Admittedly I like the 65 watt TDP of the 8400 but oh well...

    Sorry to break you brother but YOU CAN use and AM3 on AM2+ Socket, Search for MSI G45-790XT. I used to have one of these running initially a Phenom x4 9950 then later a Phenom II 1090T. With all do respect. Phenom II supports both DDR2 and DDR3, and in past I remember that the support on that board was added via BIOS update.

    Some PII support both. Not all had DDR3 support my old 940BE was only DDR2.

    The 940BE though was I believe the only Deneb AM2+ cpu? AM3 Phenom II's had DDR2 and DDR3 controllers, but one issue you may had to look at is the power design on the board in question.

    All of the 9xx PII were Deneb IIRC. 10xx were Thuban.

    You say this as though anybody was ever ok with this, which most people aren't. Every once in a while Intel had a good reason to change sockets, but most of the time it was due to poor future planning. If it wasn't that, ironically, it was because all of their planning went toward obsolescence.

    Right, Thuban was basically Deneb in a 6 core format. K10 with DDR2 and DDR3 controllers.

    Yep. Basically there were two PII's that were AM2+ socket and my dumbass bought one of them and screwed up my upgrade path.

    Only Deneb base I had was I believe the Athlon II X3 445? I had it on a DFI Lanparty AM2+ board, but man did it clock pretty well for a locked cpu! Had it running 3.8-4.0ghz no problem.

    My 940 hit a wall at ~3.6Ghz.

    The moral of the story is if you buy Intel you have to buy when a new socket comes out, or wait until the next socket. If they bring out a 'new CPU' (cough) once a year, with a new chipset, why would you want to buy the old 'crappy' one 4 months before the release? ;)

    Does anyone remember 440bx slot1 how long did that lasted ? Some motherboards could still acept new cpus after 5+ years!

    why not intel atleast promote DDR5 with new chipset. all that on new platform with
