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:

    Anyone who buys a $1000 CPU has more money than brains. If you wait six months you can buy a newer budget processor for about 1/15 of the cost, overclock it and obtain the same result. I would think that $925 would be more valuable to someone with sense than bragging rights for six months. I was taught that when people brag they are vain morons. A person's value should not be estimated by the stuff they have, but by the choices they make. We all get a lot in life, it's what you do with it that sets you apart. Unfortunately our society is ruled by greed and capitalism. I choose to speak against that. If you have a problem with that, I suggest you take it up with the greedy capitalist complaint department. They don't care either. Reply

    Hmm, it would seem to me that someone who has $1k to spend on a cpu probably has "alot of brains", hence the better-than-average financial position, enabling the purchase in the first place.

    Also, you equate greed to capitalism. This is clearly false. People get what they work for in a capitalist society. I am not saying it is perfect, though what would be a better alternative? People are not going to be financially equal, as some work harder than others. To dispute this would demonstrate a lack of say the least.

    Someone chooses to get the best. It's their money, their choice. But you're right, you should probably call them a greedy capitalist.

    wow, you said that way calmer than I would have. very classy reply to a young leftist. perhaps when obama passes the "free $1000 cpu's for lazy punk leftists" plan, you and I can pay for his cpu,and he wont be a sellout to the man by working for it. Reply

    I hate people who used that phrase "Has more money than brains". Doesn't it stand to reason, they have brains..if they have more money than you to buy the CPU... lol Reply

    Not necessarily - they might have inherited the money for example.

    Maybe you have more money than brains too...

    Yep. These people sound like they have no idea how to be frugal with money. It's ok though, a fool and his money are soon parted. Reply

    Stop doing that ok?

    If you discourage too many rich/stupid people from buying the bleeding edge stuff it just makes it harder for the rest of us.

    Poor folks like me need those rich guys to rush out and buy the expensive CPUs (and GPUs etc) and work all the bugs out, get the production line ramped up etc.

    Then 6-12 months later we have good and cheap stuff to buy.

    The best CPU costs way less than an expensive house anyway, so it's not like he's going to cause some sort of nation wide or global financial crisis.

    Maybe they don't know how to be frugal with money.

    Maybe they don't NEED to be frugal with money.

    Sure, a fool and his money are soon parted - but so is a brilliant rich man who has more money than he needs.

    I disagree with your first statement. There are people who simply want the best/fastest and will pay the money for it. Only in the last 3 or 4 years has top of the line performance become relevant only for gaming. A few years ago all sorts of pros needed the fastest they can get their hands on and purchases like $1k per CPU were actually justified.

    Now just because you can't afford a 1k CPU and never have been, doesn't mean people who buy such things are morons. Same goes for buying a Ferrari by the way. Quit being a jealous putz, thanks!
  • JonnyDough - Tuesday, September 08, 2009 - link

    When you compare value ratios, yes. A $1000 CPU is soon worth about $75. A Ferrari sold as parts is worth about 1/15 of the price also. I didn't think I'd have to spell it out for you. Reply
