My friend insists that this processor: http://ark.intel.com/Product.aspx?id=52206&processor=i5... Will work in this board: http://reviews.cnet.com/motherboards/asrock-x58-extreme... and I'm concerned because I can't find any confirmation on an LGA1155 socket processor working in an LGA1366 socket board. Can anyone confirm this and explain this to me before I make the purchase? Thanks!

Your friend is incorrect.

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?

No, there is only one type of LGA 1155 socket. It's not compatible with DDR2 memory though -- you will have to replace that with DDR3.

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.

Hey, thanks for the info guys. :) 
I just have a few more questions then:

1) would the i7-950 ( http://ark.intel.com/Product.aspx?id=37150&processor=i7... ) work in that board? / would it be worth the extra 10 euro to get the i7-960?

2) alternatively, would the i5-2310 ( http://ark.intel.com/Product.aspx?id=53445&code=i5-2310 ) work in this board: http://fr.msi.com/modele/intel-p67 ?

Thanks!

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.

can some one tell me why they cant do a sandybridge tech for a 1366 socket ?

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.

Oh, wow! I'm glad I checked this again before purchasing :) . So basically, if I've understood, by getting a LGA1155 socket board, or Sandy Bridge, such as this one: http://fr.msi.com/modele/intel-p67 . I am safe for upgrading my processor down the road once with these Ivy Bridge processors as they will be compatible with my board? Again, thanks a lot for all the help. :)

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

You left out P67 - and you call yourself an enthusiast! :ouch:  :D

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".

Good, now you've got the general idea.
However, I foresee that although Ivy Bridge (IB) will support LGA 1155 socket processors, they might not work with any current LGA 1155 socket motherboards. IB may need better hardware architecture or whatnot to function that current motherboards do not yet support.

anyone going to answer why Intel do not upgrade the 1336 processors to sandybridge tech ?

It would bring more life into the platform surely..

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.

agreed - the core i 5 1156 board life is far to short in my opinion infact i cant even buy a 1156 board in micro atx from my trade suppliers anymore

f - ing rediculous

what about intel assuring us that the socket 1366 boards woun't become obselete anytime soon. I geuss they think a few month is a long time.


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

Yes, I did forget to include the P67 board. The Q67 chipset is used in business oriented boards. There is also the B65 and Q65 but are not used in many boards.

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.

Leaps-from-Shadows said:
Assuming the confirmations I've seen are correct, pretty much all of the consumer-level boards (H67, P67, Z68) should be compatible with a BIOS update. I don't know about the cheaper business-level (H61, B65, Q65, Q67) boards, or the mobile versions though.

I have my doubts that any current motherboards won't support Ivy Bridge as it requires the H77, Z75 or Z77 according to the LGA 1155 Wikipedia article.
New processor, new board.
Why would Intel miss out on an opportunity for more cash?

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.

yeah as i keep saying tho - atleast intel had the balls to sort it unlike amd did when the first Phenom came out with the bug..

they just got mobo suppliers to patch the bios effecting performance.
