    "For anyone wondering what this is for, it's a special order for stock trading systems. They depend on strong single core performance so in this case the 4.4ghz was more important than the extra cores"

    "These were to be used for High Frequency Stock traders, and other such high speed transactional processing, where the ability to complete trades as fast, and reliability as possible is the entire nature of the business. This means that single thread performance is far more important then having multiple core, and as such, the X5698 uses a 6-core die with only 2 cores active, but retaining access to the entire 12MB of L3 cache. Clock speed was fixed at 4.4GHz, the cores did not reduce frequency as processing demands changed, as this would introduce uncertainty in how fast it would complete a given task. Doing task ‘X’ should take a predictable amount of time"

    There's something you don't see everyday.

    Interesting.... But not any more interesting than about $20 a piece to me.

    As a collector of CPU's, I'd want one of these but not at those kinds of prices.

    I’m a big fan of 1366 stuff, though I have to agree with you. This is extremely cool, and I’d love to OC this thing - but a tough sell at half that price. I have a 990X that runs @ 4.5ghz, has nearly identical silicon, and all its cores enabled. If this chip had something added (instead of removed) I’d feel differently.

    I heard they also had a similarly clocked quad out for HFT too. Never seen one.

    That kind of money (also the X5698), I think pedigree is going to need to be verified. I have zero doubt of the attraction of forgeries, considering most would never make it into a socket anyway.

    Neat chip. I wonder if you can run them in a 2-way or 4-way config? I don't remember if x58 platform could do 4 way but if it could, that'd be a pretty sick setup having 4 of these locked at 4.4ghz.

    But why? You would still only have 8 cores AND on a multi-socket board you would be limited to DDR3-1066.

    LGA1366 is a whole lot better with faster RAM speeds. 1066 sucked for some games, causing stuttering, etc. It gets a lot nicer once you get the RAM speed up around 2000.

    And you could run a quad or hex-core at around 4.2Ghz which would smoke the 4.4Ghz setup with slow RAM.

    I have a dual socket x58 board and I run ddr3-1333, is quad socket different?

    Also why the fuck would you be gaming on a setup like that lol....
    Anyways there is only a handful of dual socket boards that can OC. I doubt there are any quad socket boards that can do it.

    edit: actually I don't think there are any quad socket lga1366 boards.

    Also check this out: dual socket lga1366 with overclock support courtesy of EVGA.

    though IDK if you can OC the memory

    Getting my server stuff mixed up... up to a certain capacity, you can normally run non-registered at 1333 provided the CPU supports 1333 by default. Past that, you have to have Registered DDR3 or else it will drop to 1066.

    Yeah, the RAM would overclock on that board. That would be an interesting case for that CPU. I wonder how much headroom those X5698 CPUs have. My guess is not very much. Anybody wanna buy one and find out?

    Omg never knew these things existed. If this dualcore chip could do 4.4ghx stock on 32nm nod thinking what would 9928x i9 would do on dual basis ? 6ghz+ ?
    If that only existed
