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:

You definitely ARE stupid.dragunover - Tuesday, September 8, 2009 - link
Readers aren't, but you didn't read...snakeoil - Tuesday, September 8, 2009 - link
wow, this lynnfield is expensive, and the motherboards are expensive too.this is a crippled core i7 and you will have problems because the northbrige only have 2 x 8 pcie express electrical.
so if you are going to buy a new directx 11 video card don't commit the mistake of buying a lynnfield which is crippled.
without hyperthreading in some cases is a 40% slower than core i7

Anand, can't you just ban this guy? He's always trolls against Intel here, TechReport, and a couple other tech sites.JonnyDough - Tuesday, September 8, 2009 - link
I second the notion.Chlorus - Tuesday, September 8, 2009 - link

Your comment will not affect people whose committed to bought these. I think it is more valuable than any AMD platform. I don't think AMD will survive next year.TA152H - Tuesday, September 8, 2009 - link
From a purely processor perspective, I'd agree, but AMD platforms are pretty strong when you compare IGPs. The G45 compared to the 790GX is worse comparison than the Phenom II compared to the Nehalem.Don't forget IGPs are a HUGE market, so it's not an unimportant consideration.

Yes, the IGP market is huge and Intel dominates that market as it is. If Intel can get its drivers right, then it looks like the IGP on Clarkdale/Arrandale will extend that domination. If you want to game seriously on graphics intensive games, then don't use an IGP.ash9 - Tuesday, September 8, 2009 - link
broaden your horizons; the real money is in corporate retooling- that said AMD's platform is without question offer more bang for the buck, considering corporate needs...most corporate folk have gone blind because of Intel's IPG's (laptops and desktops)Anand how bout running the tests that addresses that issue (IPG's and eye strain)
