LGA1155 i5 processor in LGA1366 board?

Hi, thanks for the reply. I suspected this to be the case
Could anyone recommend a board that would work with that LGA1155 processor (as I think there are two types of LGA1155 slots? /confused) and also support 2x2GB DDR2 PC-6300 RAM and PCI-E 2.1 support?

There is only 1 LGA 1155 socket and it is being used on motherboards using the H61, H67, Q67, and Z68 chipsets. With the memory controller located on the processor only work with the DDR 3. So if you some old DDR 2 you will have to change that out.

The i7-950 uses the LGA 1366 socket.

Basically, there are 4 types of i7 processors out there.
1) i7-8xx, Lynnfield (45nm), socket LGA 1156
2) i7-9xx, Bloomfield (45nm), socket LGA 1366
3) i7-2xxx, Sandy Bridge (32nm), socket LGA 1155
4) i7-9xx, Gulftown (32nm), LGA 1366

And that MSI board has the LGA 1155 socket which fits the i5-2310.

they are not coming out with the sandy bridge type tech for the 1366 socket...They are coming out with the next generation 1366 tech, which will be the LGA 2011 socket. new socket, enthusiast chip. It is due out in the 4th quarter this year. it will use quad channel ram...so new motherboard, new ram and new CPU

ok ill refraise it...


Socket 1336 is it technically possible to just put a sandy bridge edition of a core i 7 - 955 if you like in production

i mean 2011 is just rediculous amounts of pins for a processor

Thanks a lot for the help everyone. So basically, of the numbers you listed, (2) and (4) would fit the same boards? (3) requires a different board, and (1) requires yet another different type of board socket?

Anyway, I think I will go for the 9xx processors, though seems like it may be over kill for games such as Diablo III which is what I aim to play with it . I'm just hesitant to get the 2xxx processor if it will only fit out-dated boards. Might cost me a lot more money down the road, right?

O no, I believe I've mislead you.

The i7-9xx processors are great and all, but only for the most extreme enthusiasts. Get it if you like to play Metro 2033 with Ultra High settings, zip a 10GB folder and encode a 1080p video all at the same time.
And correct me if I'm wrong, but from what I've read, the LGA 1366 socket will soon be replaced by the LGA 2011. Thus, Intel will produce no more processors for the 1366.

As for the LGA 1155 socket however, Intel will continue developing it with yet-to-be-released- Ivy Bridge chipsets.
Question is though: Will current processors support Ivy Bridge?

Edit: Ok, so Ivy Bridge will be compatible with LGA 1155.

It's all pretty easy. If the numbers do not match, it doesn't fit

Sometimes its better to explain things the simplest way possible and work your way up.

The reason as to why certain processor dont fit in certain motherboards is because the processor's "pins" dont fit in the motherboards "socket". The LGA number is the actual number of pins. For example, Sandy bridge processors have 1,155 pins, therefore, needs a motherboard that has 1,155 sockets. This is true with AMD processors too. With that out of the way, a processor with 1366 pins will not fit a motherboard with 1155 socket holes.

Note: Before i get flammed, I know Intel's chips do not have actual "pins", however, the concept is still the same. And yes, I know that LGA does not always relates to the number of pins. I just wanted to keep it simple. Like bearclaw99 said "If the numbers do not match, it doesn't fit".

lol, he probably meant P67 instead of 'Q67' anyway.

It probably has to do with making more money by selling more motherboards. The rate intel burns through sockets lately is getting ridiculous. I doubt removing 1 pin from the 1156 socket was absolutely vital for Sandy Bridge to work.

They will have had a 3 year life-cycle before LGA 2011 replaces it, and Intel will continue selling CPUs for sometime after that.

do tell why with out warning that intel withdraw a chipset for motherboards and drop the socket like a stone down a deep well.

i mean socket 775 chips are in more supply than socket 1156

what gives ?

To an earlier question about IvyBridge, its my understanding P67 and Z68 motherboards will both support IvyBridge processors.

Ivy Bridge doesn't require the new chipsets.

I think the reason for the new chipsets is to get rid of the "SATA bug" stigma. Even Z68's adoption was affected by it, and Intel is hoping to finally leave it behind.
