Looks just slightly larger than LGA1366 to me.
Though what I'm wondering, all boards only have 4 dimm slots? Since the chip is supposed to have 4 memory channels, does that mean you need to equip all memory slots (and can't upgrade then without removing old memory, not that I'd really expect much of a performance difference between 2 and 4 channels), or do these boards only implement 2 channels (with 2 dimms each)?
In any case, seems some step backwards since LGA1366 almost always had 6 memory slots, if you only have 4 you lose the advantage over LGA1155 if you just need all the memory you can get... Obviously, ideally you'd have 8 memory slots on a LGA2011 board I suppose.

From what I've heard, socket 2011 CPUs support only 1 DIMM per channel (for signal integrity reasons, I presume)... I dunno, maybe this was based on old or bad information, it's quite a while since I heard this. Anyway, how often do you really upgrade your RAM these days, don't you kind of buy ENOUGH, and then use that memory until the system is retired? I know that's how it worked for me in my last 3 PCs.

that's because you can afford it. it feels stupid, I thought socket 2011 and the fourth channel were made by Intel to increase memory capacity in server. you'll see that on "pro" boards with registered memory.
users that want huge memory on the cheap will have to buy a socket C32 motherboard, the CPU are slower but you may afford two C32 opteron for the price of one six core Intel CPU.
When will the first PCIe 3.0 graphic cards launch ? Strange that noone mentions the PCIe 3.0 slots. (even on sites like anandtech)
that's because you can afford it.
RAM isn't so expensive these days (and I'm not rich). It's not like the early 90s, where a 30-pin stick of 256kB DRAM cost a hundred bucks... :razz:

Xeon CPUs will probably see Intel's new fully buffered DIMMs implemented, letting you install ginormous amounts of memory (at least 2TB or somesuch with current memory density I believe); "only" 4 DIMMs for lesser servers, workstations, and power users should still be quite sufficient. After all, nothing forces you to populate all 4 right away; memory bandwidth is rarely a bottleneck on modern PC CPUs and probably won't be on the SNB-E either, with the gobs and gobs of cache it will have.

Good for AMD then! :D
Wow one slot per channel is true, I remember a year ago some of you guys said Intel wouldn't do that. 4GB stick is pretty reasonable now, so I guess its alright I guess.

I don't thikn it's easy for ATX motherboard contaning 8 memory channels.....We shall remeber although X79 is just a single chip, there're a lot of items which also needs room too.
There are LGA2011 boards with 2 sockets per channel, for a total of 8 DIMM slots, so it IS possible after all. I kind of suspect they're extended format ATX though, but I might be wrong there, I haven't studied the pictures that intently since I'm going to skip upgrading my CPU this generation. Since consumer SNB-E lack PCIe 3.0 anyway it won't make a very tempting upgrade IMO; nothing I do is CPU limited anyhow. My Nehalem 2.66GHz chip is still rocking hard (running slightly overclocked at 3.4 with stock volts).

Same here (my Nehalem is at 4GHz). I could, though, jump from 6 to 12GB RAM as intermediate upgrade option... and have some fun with RAMDrive. ;)
I will probably wait till post-H2 2013 timeframe for a major upgrade to Haswell.
You can do 4GHz without bumping volts? That'd be interesting, although I dunno how my system would cope with the extra heat, it runs 80+C already at full load in my rather cramped chassis.
Not really -- 1.296v in idle and 1.312v for peak load.
Is your CPU rev. C0? Those first Nehalems were pretty hot even with mild overclock.
CPUZ says C0/C1, dunno which. Or if it's one and the same. It's Model A, Stepping 4, bought the CPU in february or march 2009 I believe. Not sure when it first came out though.
Yep, you have a real hot brick there.
Yeah well, not that it matters much, as 3.4 is plenty horsepower as it is. I don't see what would be significantly better-running with the CPU spinning at 4GHz. Maybe if I still ran folding@home, but I don't anymore due to their clients being so poor. Or were, last winter anyway, not sure if anything has changed.
I do sometimes run seti and milkyway projects through Boinc during the colder months though, but again I think the speed increase would be relatively minor. I'm certainly not going to bump the volts to 1.312V that's for sure, that's like 10% increase over stock or something. :razz: That'd make a significant increase in heat output.

v7 beta is doing his job.
Ok, I'll take your word for it, because last I tested both the SMP CPU and GPU clients had a propensity to just throw away all work done on a partially finished work unit (including those that my PC had already burned kilowatts of power chewing on over the course of 12+ hours) whenever it decided the client had not been shut down "correctly". Even though it also checkpoints regularly.
The "incorrect" way I shut down the folding client? Powering down the PC for the night.
So I said fuck that to F@H, and I've not bothered with it since.

Got pictures or at least model number on those LGA2011 board, I want to pre-order mine ?
What's the deal with PCIe 3.0 ? I thought performance wise, it's pretty small improvement with those PCIe iteration. Or can't PCIe 3.0 board fit in PCIe 2.0 ?

C0 = Core i7
C1 = Xeon
They didn't change the Model/Stepping code for some reason, so CPU-Z can't differentiate, C1 was validated for DDR3-1333 which i7 never officially supported.
Desktops went straight from C0 to D0.

Like I mentioned, I don't follow LGA2011 that closely since my current system is still more than good enough, but if you can stomach the Swedish, here's MSI X79A-GD65 8D (http://www.nordichardware.se/nyheter/76-motherboards/44468-msi-x79a-gd65-8d-tittar-fram-kommer-med-atta-minnesplatser.html), or the Gigabyte X79 G1.Assassin 2 (http://www.nordichardware.se/nyheter/76-motherboards/44459-foerhandstitt-pa-gigabyte-x79-g1assassin-2.html), they both look pretty cool (don't ask me WTH is up with those weird product names though, because I don't have the first clue... :lol:)
Actually, on closer look the Gigabyte board only supports 4 modules, so scratch that one off your list, unless you got a fetish for its black/neon green color scheme. ;)

Mainly just future proofing. I don't like the idea of buying a new, very expensive CPU that doesn't support the latest connectivity tech.

Ah, I see. Well, it's an i7 for sure, so C0 it is then. It's running very well with 1660MHz DDR3 by the way, validated or not. I gotta say, Intel absolutely builds some really top-notch memory controllers.
Too bad they can't design a discrete GPU if their lives depended on it though, but maybe both ATI and NV ought to thank their lucky stars Intel can't perform in this regard; if it could get it up, they'd get screwed so bad... ;)

as there are news about delayed sandy bridge Xeons, I've just learnt of a LGA 1356 socket. that feels mad. three sockets now!
it's basically another LGA 1366.
I assume it doesn't target the consumer, as the spot is taken by single socket 2011.

I thought that socket rumour died ca. 1 year ago, didn't it?
i7-3960X vs. i7-3930K (15M vs. 12M L3) (http://coolaler.com/showthread.php?t=276465)

Anyway I'd like to ask a question, do somebody exactly know how much and what kinds of ALU are there in one single SNB-E Core?

Asking for alus in "SNB-E" doesn't really make much sense though as it's certainly exactly the same for any Sandy Bridge cpu...
The cores and ALUs of SNB-E is just plain ol' SNB AFAIK, there's just more cores, and more cache. And more I/O, of course.

Why is there so much cache on this beast? Wouldn't that area be better spent on more logic? It seems like there's hardly any difference at all between the 12 and 15MB variants.

It's for the server/HPC applications mostly. With the increase of the memory bandwidth, the data pre-fetch becomes more efficient and that requires more cache to utilize it.
