I ran into a memory issue on a machine with 96GB of RAM where the program I was using needed to unroll a for-loop and it hit 100GB of RAM usage and then ran out..

 
That's pretty impressive, managing to run out of memory using just one app in that sort of configuration. Time to rent some supercomputer space :D

If I was interested in the SR-X (not saying I'm not, heh heh), I would be less concerned about whether it had 12 or 16 DIMM slots and more concerned about whether it officially supported 8GB and 16GB DIMMs. A 16x16GB full complement of RAM would be 256GB. There might be someone out there who can use all that physical RAM, but I'm not sure who that is.

Does anyone sell 16GB  modules yet? I've never seen them.

 
Why get 16GB sticks when you can go 32?

Here's some 16s: http://www.crucial.com/st...MODULE=CT204872BB1067Q

I'm sorry if this is something that has been covered but I've not come across any clear answer. I feel this thread is appropriate for it and that this shouldn't be considered hijacking, apologies if that's not the case.. Question:
Anyone know if the SR-3 will support ECC and / or registered memory? I got a pretty conclusive "no" when looking into ECC support on the SR-2 and I just happen to be one of those people that prefers it (ECC, not FB support.) Not looking for a debate on the issue just an answer. Thanks 

nivekt Function over form, I always say. Im sure there is a very good reason for the layout. Besides, with that layout and 8gb DIMMS, the possibility of 96gb of ram exists. Is that not enough?

No you can never have enough memory!
Because actually, one of the main reason for me to consider the SR-3,  is to have as many dimm slots as possible , and to be able to use 96/128GB of system memory, to make a RAMDrive.

As noting beats a RamDrive in assess speed and transfer of files!
And with 16 dimm slots, i would take the SR-3 and the extra cost, over any other board with 8 slots, But with only 12 slots its more of a toss.

yeh i agree man... to just build this around sandy bridge is really quite not good enough... considering pci(e) 3.0 is ivy well they will be very outdated...
 
i am waiting for this before i build a new machine, i never bought an sr2 because I knew its simply not good enough for what I need and lets see if this new board will be...
 
I do have big faith in them... I dont think its going to arrive when we are expecting... I think our prayers will be answered.
 

I'm starting to get concerned about how the E5s are going to overclock. Apparently the ES chips anyway have their straps and multipliers locked, so they overclock about as well as a vanilla Sandy Bridge like a 2500 or 2600.

Limitations

[] Overclocking

Due to a single clock generator controlling the speed of all electrical buses, of -1155 compatible processors beyond the default 100 MHz base clock speed is very limited, up to 5-7% without other hardware components failing. However, Intel has made available K-edition processors which feature unlocked multipliers; the highest multiplier for Sandy Bridge is 57.
Intel has demonstrated a Sandy Bridge CPU running stably overclocked at 4.9 GHz on air cooling.
Intel Sandy Bridge E-series Processors will come with "Performance OverClocking" support.

[] Chipset

Non-K edition CPUs can overclock up to four bins from its turbo multiplier. Refer for chipset support.

 
 
is wrong , the lga2011 is overclock by bus speed and multiplicator  is not SB 1155
search on coolaler site ,

Im also certain that is correct... Its not actually denying what you are saying...

use google web translater all pages

Actually, each of the i7's have different variables for change.  The postponed 3820 has just the strap ratios and can have it's stock 36x multi lowered to enabled any frequency up to 6GHz.  3930K had 3820's features plus the unlocked CPU multiplier, while 3960X has 3930K's features as well as variable bus.  Theorhetically both 3900's can reach 9GHz although I have yet to see any WR run using the Strap ratios as even the fastest 3960X's don't breach 5.8GHz.  It's pretty pathetic seeing how a 980X was able to reach 7Ghz last year, unless there is a cold bug these early i7-3900 steppings no one is talking about...
 
In the SR-2 environment, RAM divder was not unlocked and speed could only be increased with Bclk, while only Bclk increased CPU speed.  Sandy Bridge changed the rules by locking or limiting the reference bus, leaving any CPU/RAM adjustment highly dependent on strap ratio and multiplier adjustment. 
 
My tentative guess with lower-end Xeon E5-2600's, the strap ratio and system clock may be locked and only allowing a few bins speed increase, just like non-K parts in LGA1155.  This means there is a chance of a very limited RAM overclocking in SR-X and only adjustable with pre-sets similar to X79, if any.
 
I think it is worth being concerned if Intel were to limit full-flexibility overclock to the expensive E5-2600's.  Why would Intel want their lower-end Xeon E5's to outsell better than the premium models?  It would make sense to botch the level playing field. 

Trying to get some info off vince aka kingpin about this board, seeming as he did 4 way under ln2 :D

Guys the latest Xeons C0 ES do not support straps and only support the usual Turbo ratios i.e they are not unlocked. Only way to clock em is BLK from what I can see and this means like 107 - 110 BLK tops!!! Very poor really.  I tried on Asus R4E.

There has been very little talk about OCing with the straps other than to say that the highest strap is unusable.

I'm thinking i7-3820 will introduce strap ratio overclocking to the world to get some attention on it.  I just don't see why there aren't many with SB-E's doing it already ready.  It is almost like LGA2011 users are spoiled by the LGA1155 approach of CPU multiplier only adjustment, so they "do what works" instead of getting creative.

When SRX will release?

March 2012, just google when the Xeon E5's debut. FYI, it is the same month as when Xeon 5600 and 5500 debuted.

Well, on one hand, ES' usually aren't representative of retail.  Though, on the other hand, the typical Xeon customer isn't an overclocker, it is an organization that deploys dozens or hundreds of these processors at once.  Each segment will see their purchase as drop-in-the-bucket depending on their revenue, while overclockers tend not to make money from their builds, hence our hesitation (albeit breif) with high prices.
 
I won't be surprised if Intel takes an X79-style approach to limiting overclocking to a handful of pricy Xeon E5's, to prevent overlapping with either LGA1156 or X79.
 
Although, with Skulltrail and the Asus counterpart, then SR-2 and SR-X with the rumored counterparts-- it looks like the dual-CPU enthusiast market is growing, so the selection of Xeon E5's might be relatively decent.

I use the 1.25 strap when clocking my 3690x for 24/7 to 5125ghz linq stable with 32gb G.Skill @ 2333mhz. So I personally do use a strap yes!!!

May I ask what is your CPU's FPO/Batch number, either on the retail box or CPU?

pazza3169

None of the current ES CPU's evan what is gonna be the flagship 3.1ghz has unlocked multi or CPU straps enabled.

How many different ES part numbers have you had the opportunity to test? I'm wondering what is the differnce between the E5-2687W and other parts (other than a higher TDP) if none of them have any of the overclocking features unlocked?
