Intel plans to deliberately limit Sandy Bridge overclocking

[-Sweeper_]

drwho, can you say anything about the third gen atom?

[Movieman]

I can t answer those kind of Question ... I love my job too much ;-)

Can you answer mine from above?
Thanks for the info..
Will we see dual socket SB boards?
( and when,chips I can get, boards you have all locked away for yourself!

and one more..will SB be limited to 4 cores?

Actually he's already mentioned dual socket SB.

Well, sandy bridge generation will have dual CPU too , what was your point?

[Hornet331]

and one more..will SB be limited to 4 cores?

Why shoul SB limited to 4 cores?

SB is the name for the whole µarch, so we get teh full spectrum. Form dualcores up to 8+ cores.

Hush guys, MM is asking tricky questions to get him talking about the real deal. He didn't fall for my trick tho.

yeap, it is much faster than arm ... with better low power ...
(Now, i ll get a lot of hate mails ) hehehehe ...


This is my opinion, it is ok to disagree, not ok to crusify me

Let 's close this thread ... all was said ... Intel does not have a crazy plan to stop overclocking, otherwise, i would have hanged the dudes in my attic (Metaphore)

4 cores for 1156, not sure of 1355

Now we just need dual core versions, running meego with a decent gui ^^

Any chance of pushing for external reference voltage control for internal receiver lines on critical signal stages? I know all references are internally derived (makes sense from many perspectives). This stuff is all automated now and I wonder if we can increase clocking margins somewhat on some processors with a manual shift - the effects of sub-zero temperatures on certain Tx stages can change voltage swing.

[QUOTE=Hornet331;4483956]Lol reading that paragraph you are beliveing that engineering only consists out of luck?

What vdimm issue? If you allude to the 0,5V "issue", nope its still there. If you want to kill your nehalem cpu fast just increase ram voltage 0,5V above the qpi voltage and watch it die (over several days).

err no? what makes you think so?
ive run vdimm and vtt over .5v apart for 2 or 3 weeks without an issue...
vtt was 1.2v and vdimm 1.9...
it wasnt stable, i thought the mem was dieing but then saw vtt was at default... i must have had forgotten to adjust it when i tweaked the system 2-3 weeks before i noticed this.

and no, i dont think it has anything to do with luck
where exactly do i say something that sounds that way?
the part of my post your quoted doesnt hint at luck at all...

@ saaya

well thats what i said... its 22nm, not 16... i guess i misunderstood his post, it sounded as if he was saying haswell was 16nm...

Do you really Think that the parts out there has final tuning in? look at the stepping ...

SandyB is very different than what you are use to ... may be you are a little bit over confident ... To quote morphius, "Don't think you are, know you are!"

in my case, I prefert Kouros ... Houston is not launching as much space craft than Kouros. ... and i am in perfect synch with what I know about SandyB

no, i never said that and im sure the final parts will be a few % faster per clock, i noticed the same with lynnfield... its funny cause what i wanted to hint at was you sounding overly confident that you are the only one out there with accurate sb information... and you reply telling ME that i am overconfident...
well im not making any big claims, and in this thread i havent made any claims about performance or clocks at all... so why are you telling me i sound overconfident?

lol at kuorus

oh one more thing, can you say anything about skulltrail2?

It's been shipments in Q4, launch in Q1 for a long time now. Some dope wrote an article saying it was coming early after misinterpreting Otellini's CC comments that the SB *ramp would be faster* due to strong customer interest. Intel did not say anything was coming *sooner*, and Intel has repeatedly said that customers do not care for Q4 launches, they prefer Q1... so even if they COULD launch it in Q4... they wouldn't.

your saying sb wont come out until q1 2011?
or 1355/2011 wont come out until q1 2011?

[DavidGraham]

So , does that mean in the current generation the SB and the NB has separate base clock ?
I always thought they both relied on a single clock generator , I guess that explains why something like the PCI-E and SATA bus operate at a frequency of 100MHz .

SB 1155 is supposed to have production shipments in Q4, and launch in early Q1. So, systems and retail parts should not be available before Q1, although maybe some parts will leak into shops in asia?

SB 2011 (is there even a 1355 anymore, I think desktop may have moved to 2011?) is later, due in mid-2011.

[Mumak]

DrWho: are you running on D0/ES2 step or later?
BTW: isn't that PCU uController in SNB based on ARM core?

well i heard early q4 launch to catch the christmas shoppers... the boards are def ready...

and yes, like i said before, i havent heard of 1356 in ages... actually i never heard of 1356, i just heard and saw that there will be a 1366 replacement with vrm12 with a few pins added or removed. it would make sense if intel canned B2 aka 1356 and went for R for both MP, DP and sever and workstation SP... the costs of R and B2 were probably so close to each other that it didnt make much sense to have two platforms? especially since it fragmented the server market... and well, you want tri channel with less cores? you can have that with a socket R cpu and mainboard... just dont connect some of the pins and there you go...

so yeah, i never actually heard of 1356, all i heard of was quad channel, 8+ cores with bclock overclocking... from what i can see and read atm, im very sure that this is 2011 and not 1356...

shhhhh!
come on mumak, leave francois' home-made beef jerky in his attic and dont embarrass him here ^^

Well, I guess anything is possible, though that goes against their claim that OEMs dislike Q4 launches, and when asked if Sandy Bridge was coming early on the CC they said:

David Wong – Wells Fargo

Thank you very much. Paul, you mentioned that you are very excited about Sandy Bridge and this was one of the reasons for accelerating 32 nm, does this mean that you are planning to bring out Sandy Bridge earlier than scheduled, and when might we expect to see first launches of systems that have Sandy Bridge in them?

Paul Otellini

Well, we will talk more about the product in a lot of detail at IDF in a couple of months. In terms of product granularity, I really don’t want to get more granular than we have been which is that we will ship Sandy Bridge for revenue this year, late this year.



So, unless he is sandbagging, shipping for revenue LATE this year probably rules out a launch this year, since they like a month or two of shipments prior to launch, at least lately. And moreover, with Llano stuck in process hell, there's no competitive pressure to launch early...

[Xanth]

We are talking about upcoming mainstream LGA1155 Sandy Bridge CPUs, not the high-end which comes later.

It is a natural move if Intel try yo to limit the OC of mainstream to prevent a direct competition with hight end. I guess that's the lesson Intel has learned from i7, when we all bought a sub $300 920 and OCed it to beat the $1000 975.

Exactly!

[saaya]

Exactly!

oh come on... like this is the first time intel cpus could overclock which resulted in some people buying a cheaper cpu and overclocking it... yeah, thats never been here before

and 300$ for a 920... why do you think they priced the cheapest 1366 cpu that high? cause they KNEW a lot of people would overclock... an i7 probably costs intel around 50$ to make, if even that... dont think that intel isnt perfectly aware of this situation and adjust prices accordingly...

and terrace... no idea... i dont get why oems dont like q4 btw...
why would that be?

[mongoled]

DrWho,to get things straight, you are denying 2 of the Hans' speculations about the L3 cache located next to each core and about the SSE unit organization?

DrWho, good dodge, maybe you are re-enacting the French football team who went on strike



Would you please give an answer to informals question....

[NaeKuh]

Well, sandy bridge generation will have dual CPU too , what was your point?

Im sorry werent we talking about 1155?

Information provided by Intel in its own presentations about its upcoming mainstream LGA1155 Sandy Bridge CPUs appears to confirm the company has designed the CPUs to deliberately limit overclocking.

Didnt you say 1155 was gonna blow away everything?
Did we even get into 2011?
Isnt this article @ 1155 specifically?

Are you telling us, 1155 and 2011 are gonna be identical?

You do know who Dr Who is right? When he talks about Intel he uses the word 'we' and that not just because he's french.

Yes i know who he is... and honestly i can care less if he's gonna pull NDA gag orders.

He's trying to throw Han's finding under a Rug, and make us all deny it.

Ie.. he's trying to control information.

And im also like this to JFAMD and AMD, so Intel doesnt get a freebie from me either.

[saaya]

guys, francois doesnt have to answer any questions you know...
you should ask him in a nice way and he might actually reply, even if he avoids the main point of the question...
if you push him to answer your questions hes just gonna roll his eyes and close the tab...

Well thats completely up to him, isnt it?

Dont think he is at the age where he will throw his toys out the pram.........saying that; he is French, LOL, hehehehehee

(Yes. just kidding )..........

[FlanK3r]

Dr Who:im confused, whats SB highend platform? LGA 1356 or LGA2011 (desktop only). At next IDF we will see "new roadmap" with this CPUs? Thx

[Drwho?]

BTW: isn't that PCU uController in SNB based on ARM core?

Nop ... The PCU is actually much faster than an ARM ...

[FlanK3r]

pls, answer to me ,-). If can it :-)

[Mumak]

I don't think that this sort of info can be disclosed to public yet.

pls, answer to me ,-). If can it :-)
