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:

    Really? SuperPi, WPrime, Everest, 3Dmarks and LN2 overclocking defines a better review? How does any of that correlate into real world applications and what 99% of people use their computers for on a daily basis. I counted a lot more than three tests in the AT review, go spam elsewhere.

    Really. All I play is SuperPi, Everest and 3DMarks....oh, and Furmark and OCCT.

    Who would ever use their computer to encode video, run Excel spreadsheets, play games like Far Cry or Crysis or Left For Dead, or actually use any other real world application?

    Don't you know? Real elite computer users just bench synthetic crap, over and over, for hours and hours, and scoff at anyone who dares do anything productive with their computer.

    I am not pleased by the news; i5 needs more juice for overcloking. Thats terrible: my E8600 is still on top: it runs at 4.0Ghz with 1.16v on a watercooled setup with 4x120mm fans at 1600rpm. we are talking less than 30dB of noise and less than 55w of power consumption. At 1.25v my E8600 reaches 4.25Ghz and would go a little further if wasnt for the 4 sticks of ram burning the NB. no reason to exchange systems before the 32nm parts arrive. The ability to achieve high clocks with low voltages is crucial for a good system: not only will it consume less power, but it will also be quieter, and that is a point for choosing sub-65w dual-cores in gaming rigs.

    honestly... i lol at all the core i7 core i5 "GAMERS"( and their punny 23 lcd with shitty TN panels) also LGA1366? LGA1156? and 285$ for a shitty motherboard? XD I have a better proposition for you INTEL. how about u SUCK MY BALLS XD. MKAY? the story: my old man needed a gaming setup ( mostly simracing) So i bought the cheapest E7200 i could find (oc3.2GHZ), 4gb of ram, the cheapest intel mobo i could find -g31- ( not even pcie2) and gave him my 4770 ... the price? ridiculously cheap... almost nothing. and with all that extra money i saved i got this > a nice 42" HDTV with a perfect s-ips panel and low 1366 X 768 resolution, and a g25 wheel.

    btw, the framerates? i never, ever drop below 30fps. ALWAYS 60FPS NO MATTER WHAT, ( with nice 8xAA) XD so the best gaming cpu? the cheapest !

    Interesting. Which 42" LCD TV did you get that has a S-IPS panel? Also, a 23" panel at about 3 feet looks bigger than a 42" screen at 6 feet.

    LG. btw a 23" TN lcd looks like shit no matter how you look at it.
  • C'DaleRider - Tuesday, September 8, 2009 - link

    My, aren't you special?

  • papapapapapapapababy - Tuesday, September 8, 2009 - link

    yes, i know! btw enjoy your small screen gaming, mr sheep XD
  • chrnochime - Tuesday, September 8, 2009 - link

    I'd say the same about that barely big enough 42" LCD, but then again why bother...
  • papapapapapapapababy - Tuesday, September 8, 2009 - link

    my bad i meant this > E7300 3.2ghz (+ a cheap 24$ modded heatpipe cooler... 14 dba XD)
