The LGA-1156 Socket: Size and Installation

The first Core i7, Bloomfield, went into a 1366-pin LGA socket:

A year later we have Lynnfield, and it fits in a much tighter space:

The LGA-1156 socket and Lynnfield CPUs are about as big as the old LGA-775 sockets/chips:


From Left to Right: Intel Core i7 "Bloomfield" (LGA-1366), Intel Core i7 "Lynnfield" (LGA-1156), Intel Core 2 Quad "Yorkfield" (LGA-775)


Note the pad densitiy of Lynnfield vs. LGA-775 processors

The installation process is largely the same as any other Intel LGA socket, the difference being that LGA-1156 uses a new one-sided retention mechanism.

After the socket is "open", gently place the CPU on top of the pins. The chip can only fit in one direction so just pay attention:

With the chip in the socket and the lever still pulled back, move the socket cover over the CPU and slide its teeth under the retention screw on the opposite side:

Then, lower the lever, lock it in place and you're good to go:

    and the cherry on top of the pie

    core i5 750 and core i3 don't support virtualization.

    that's fantastic, colossal intel.

    what's wrong with intel

    Intel VT-x is supported by the Core i5 750:

    What are you talking about? These overclock FINE; read the article. 4 Ghz. Anyone that is gonna overclock bloomfield or lynnfield seriously is opting for an aftermarket HSF, so don't bother arguing that. Your comment doesn't make any sense.

    You missed the point.

    When you overclock the processors, you change the characteristics of turbo mode. Consequently, the big advantage of the Lynnfield disappears, and they run at the same clock speed, instead of the Lynnfield at a higher clock speed.

    Do you understand now?

    "There are better sites that have answered these questions. I used to like this site, but this review is another disappointment. "

    Just how is that Tom's Hardware gig working out for you? I noticed your name was not on any of their launch reviews since you seem to be an expert on the subject. Why is that?

    Thanks for asking.

    When I have time, I will be writing another article, which they hopefully will use, but to be honest, the time it takes to write an article, at least a well-written one, takes an enormous amount of time and effort.

    Getting and verifying data is only part of it. Writing it in an artistic an interesting way is very time consuming, and, at least for me, requires many rewrites of the same pages. Each page took me at least five hours, some many more, plus the upfront time of deciding which pages to write, which probably took at least 30 hours of research.

    The editor of Tom's wrote their articles, and it's clear to see the much more thorough review he did. Personally, I like him and occasionally do communicate with him, and I probably would like Anand too, since he seems like a good fellow, but I have no real affiliation with their site. If I write an article they like, they might publish it. That's it.

    But, honestly, if you do it for money, you're a fool. It takes WAY too much time for that. You really have to want to do it, and the money is secondary.

    So it took you five hours a page to do a copy and paste from Wikipedia on that so called article of yours? I read the Tom's P55 article, not seeing how it was any more thoughtful than the one here or at Tech Report. At least Anand did some searching and reported on items like PCIe clocking/voltage requirements that I noticed was not mentioned at Toms.

    Your only motive for these posts is to try and look impressive at Toms in hopes that they will publish another boring piece of dung from you. Otherwise, your complaints here are just as justified at Toms or TR, yet you are not posting at either site. That is why it is so obvious as to what you are up to with the flame bait comments.

    I never even looked at Wikipedia, since I don't consider it a valid source of information.

    Why do you talk about things you don't know about. In fact, some people used Wikipedia to argue some points with me. I made a point never to look at those pages.

    But again, what have you done with your, except produce carbon dioxide and speed up global warming? You seem pretty worthless to me.
