    [RUMOR] Industry source: Lynnfield hard to overclock



    I suggest you to take following with a grain of salt:

    A friend of mine who is working in industry has learned that Intel will be preventing Lynnfield overclocking capabilities. First of all Intel will remove 4 pins from LGA1160 socket and it will be called LGA1156.

    Second Lynnfield will only support BCLK (Base clock) 100 and 133 MHz, and no external clock signal fun like with X58 chipset. He is afraid Lynnfield won't be good for overclocking...

    Lets hope our own DrWho? will give us some early hints and hopefully he will give me a lecture just like IDF earlier this year

    that's sounds bad, we will need to find other way to oc :/ (hardware modification ?) maybe we should wait more infomrtion to confirm or not this rumor ....

    i smell modding "fun"

    oh well, guess the midrange overclockers will be sitting on their e8XXX and Q8XXX/9XXX processors for quite some time, if this turns out to be true
    system:

    Phenom II 920 3.5Ghz @ 1.4v, benchstable @ over 3,6Ghz (didnt test higher)

    Isn't this what was rumored about Nehalem as well which turned out to be completely false?

    I remember hipro's 1st overclock was achieved by replacing the quartz clock gen on the board with a faster one. Do i sense deja vu ?

    I doubt strap-on turboPLLs work with Lynnfield...
    You were not supposed to see this.

    We kinda heard this before. Tho with Bloomfield

    Also changing socket sounds odd, even if they remove 4 pins. The 4 extra pins would just be "unused at this stage.

    And the external baseclock is the same. Lynnsfield is exactly like Bloomsfield. The QPI is just replaced with PCIe ondie and only 2 memory channels. Everything else functions the same way.

    So I put this with "bloomfield" cant OC category

    I'm still thinking this could be true for the Ibex Peak based platforms. There's no apparent connect that carries the clock signal to the CPU. With any of the UP/DP/MP platforms that use Tylersburg, the reference clock must be synchronized between all the sockets and that's why you have clock generation done off die and split/distributed from the Tylersburg chipset through the QPI links connecting everything. With Lynnfield, there's really only 1 component that actually needs that clock signal, the CPU. In the effort of simplicity/cost, power savings, and maybe to some tiny extent performance, just connect the PLL directly to the CPU.

    It might just be that Lynnfield is limited to multiplier overclocking only.

    Like he pointed out on Aceshardware forum: he's only giving his personal opinions... and as he demonstrated so well in discussion about intel's "cheating" in Cinebench benchmarks, only giving them if there's something positive or hypeositive to say about his company

    In other words his silence will speak also

    anyhow, nice finding Sampsa! I guess it's only matter of hours before this hits mainstream "news" sites

    I wonder if C2 will be the last one where you actually could overclock even the cheapest model*.
    It's like Intel wants to make some room for AMD**: they have no true successor to the C2D*** and simply leaves the <$200 OCing CPU**** market*****.


    * Sure, it's all rumors, maybe you can overclock the new ones. Are they called something like Core i5 or what?
    ** No, AMD may not be able to fill that market even if it will exist, but I think a situation like this will be good for them.
    *** I'm not saying that C2 is outdated already, but if these rumors are true then it's hard to see a future upgrade unless you pay in €i7-money.
    **** Yeah cheaper €i7 may show up.
    ***** Yeah I know that very few cares about overclocking in general.

    Meh, don't think Lynnfield will even show up on my radar. So long as the Core i7 9xx series overclock well then i'll be happy. As for Core 2, I have a feel these 6+ GHz E8600s will stick around for a while

    I wonder if it'll be programmable. Would be nice if it was adjustable... Intel ya listening?

    Makes sense.... lock OC'ing on cheaper models and force people to spend the big bucks on X58, Bloomfield and make their memory partners rich with DDR3 sales...

    Problem is: after Bloomfield is Westmere, Sandy Bridge, etc. I don't know about Westmere, but Intel showed (in IDF maybe, can't remember) some info suggesting SB will use the same CPU+IMC+PCIe on-die Lynnfield uses, and I must say it's the logical next step. If that turns to be true then the overclocking results and methods of Lynnfield can be very important to determine how the overclocking world is going to be in the future.

    They'll strick themself so badly it's gonna hurt them.
    Profit comes from massive low and mid range sales, not from high end.
    So those who were thinking of buying CPU went with Intel just because of overclockability. Otherwise i'd probably go with AMD in the first place.
    At least i know i bought Intel just because of that.
    I'll rather buy cheaper LGA775 quad and overclock it and use it till AMD releases something decent or Intel gets over such lame attempts to milk the users...

    The socket change 1160->1156 is true.
    BCLK is routed thru the PCH.

    There will always be a need for Tylersburg or Tylersburg-like chipsets with DP and MP configurations, as a QPI "hub" is needed to function as a central hub for PCI and clock synchronization. Bloomfield and the X58 platform is an extension of the DP platform, down into the high end desktop market to satisfy those in this community that enjoy overclocking. Don't worry about Westmere and Sandy Bridge, as there will be HEDT platforms for each that will fit this market. As with nehalem, there will also be the same type of systems as Lynnfield/Havendale with more portions integrated to satisfy the mainstream market.

    Please again remember that this is not Intel "locking out" overclocking. This is Intel making choices that result in large gains for the items that people who do make massive low and mid rage purchases want. Having a NB on a mainstream platform with Lynnfield's architecture is a complete and total waste of power and money. It's another chip that motherboard manufacturers have to place on the board. It uses extra power, generates more heat, increases cost, and increases complexity of the platform. All things that the people who make massive low and mid range purchases avoid.

    You're contradicting yourself quite heavily there

    Majority of profit comes from vast quantity of low/mid end sales correct. If they lock Lynfield/Havendale chips, Dell, HP, Joe's PC will not give a crap (i.e. 99% of the buyers). But a lot of overclockers will give a crap.

    The largest profit per unit is from high end CPU's (i.e. Q, X, QX). If they can force us to buy more expensive gear when AMD has no reply... = win for them.

    So it would not surprise me if they did lock down the FSB...

    I have a feeling there might be another BSEL mod? Or does that only work with FSB/multi type chips?

    You seem way more optimistic this can't be so than the actual Intel employee here! Do they keep the viral marketing team out of the loop nowadays?

    I don't know nothing either, I'm just guessing. But I don't want anyone to feel a false sense of entitlement either. If it turns out locked or just really hard to get them to clock higher, it's not cause Intel is trying to screw you out of your hobby and force you to buy Bloomfield. It is because the platform just works better for mainstream users this way.

    I'm still of the opinion that People like DrWho? and others who were helping decide the direction of the Nehalem generation of platforms, saw that the desktop platform was turning more system on a chip. And realizing that this type of platform had limited room or mechanisms for pushing the boundaries, they made a conscious decision to pull the server platform in to fill in that role. Keep in mind that Tylersburg is a server chipset that happens to work very well for a HEDT platform.
