To bad they hit 96c at 4.7Ghz with a Corsair H100:shocked:
at air/water they cant oc that much, only on Dice/LN2!
Thx, I was wondering if that could be true because all of misleading information receveid earlier.Quote:

No, you need an ivy bridge cpu to get PCI-E 3.0 on a Z77Quote:

I'd be OK with an Ivy Bridge setup at 4.5Ghz if it didn't run too hot, but I usually use Air Cooling, so I'm not even sure if that will be good enough at 4.5Ghz if the temps are reaching 96 degrees at 4.7Ghz with a Corsair H100.
Mind something, only in one of this 3 situations IB is hotter then SB in the other two they have around the same temps ( if one is cooler then the other that should be IB ).
-Gaming
-Idle
-Full load
So if I got it right, IB is hotter than SB because of the smaller die size.
Will this affect Haswell too? It's supposed to be even smaller, isn't it?
Nop Haswell should have the same 22nm that IB has.
Please some1 tell us Intel can't have failed this much with Ivy, that people are concidering going with Sandy Bridge instead of Ivy (for those not owning a SB yet) is not a very good sight.
odd that 3770k TDP is higher than all the previous documentation. I wonder if the e3 xeons will also be hit.
it is possible that there is a lot of voltage variance in these chips, and the low volt ones will be e3 xeons. I doubt it, but I guess it is possible. so we may see 77W tdp ivy bridge chips yet. just not overclocking ones.
For a 24/7 OC machine i would easily go IB... It may run abit hotter but power consumption will be lower.
Will it really be lower though when starting to approach 4.5GHz+ clocks is the question as it seems that's whereabouts the temps also starts to climb quickly.Quote:

LOL if you guys can't wait for retail 3770K at local store
http://www.ebay.com/itm/Intel-Ivy-Br...item3f164e8f7f
maybe this 3770K is special one with 77w TDP that's why it's priced that high
Special?I don't think so. It also has 6Mb cache, it' the seller that doesn't know what he's selling :shakes:Quote:

With above in concideration I want to congratulate the early Sandy Bridge adopters for making a good decision, I wish I had been one of them. 5% or whatever more performance there will be for air clockers for how much more months waited? By the typical trend IPC boost may be like 5~10% for a dieshrink but better overclockability also added like 10~15% performance gain so we were more talking about like 20% perf gains. This is why I'm not that happy about it right now if it turns out to be like there's been hints of. Yes you have to upgrade at some point but it's all about to foresee how much of a performance gain a new generation will deliver that decides it for me if it was a good decision or not to wait. It feels better picking up a chip that u know performs 20% better than previous chip for similar price than buying a chip that costs similar (talking in terms of launch pricing) for 5% more performance than the previous gen.
I see a lot of talk about temps and MHz. What about the power consumption?
Ivy is only 6-8% better if they are at same clock speed, if you got a 2600k chip there can 5Ghz+ there NO reason to chance to 3770K, it will be a jump down in performance.Quote:

Assuming a more realistic real world stats: Loaded 25% of the time , 12 hours a day , for 365 days
idle = 2.5 watts * (.75 * 12*365) = 8,212 watts per year @ 12 cents/KWhr = 98 cents
load 27.1 watts * (.25 * 12*365) = 29,674 watts per year @ 12 cents/KWhr = $3.56
I guess you can goto McDonalds and buy a Big Mac with no fries or coke off your savings.
"there NO reason to chance to 3770K, it will be a jump down in performance. "
-unless some ib's run @ 5.0 7\24 once larger samples of batches get benched in the next few months , but of course you can always turn the 2600k up to 5.3 7\24 air?
time will tell.

Well if there's like 27W difference comparing stock 2600K vs 3770K I bet there will be next to no advantage by 4.5GHz-4.6GHz, probably 5~8W or so advantage for 3770K at best. Hopefully at least some reviewers will compare OC vs OC results too.Quote:

Same everything ( CPU clocks, GPU clocks, etc )
I aggree with all except for the bold part, with IB and 1.2v you will get a hell lot more then 70s with the best aircooler there is. I would say like midle 80's. See the bright side there's no need for 1.2v to run at 4.5Ghz :)Quote:

What sort of cpu score do you get in 3D11?
:D
I'm guessing he's talking about Virtu MVP vs no Virtu MVP
If that's the case I just want to point out MVP has nothing to do with FPS, there's a good article out there which explains it all and it's intended feature is reducing/removing input lag and tearing (Nice!). The way FPS is read is inaccurate when using MVP and the article clearly stated it really doesn't boost the performance (FPS) at all and is not its intended purpose which seems like most uninformed people are believing and therefore calling it "BS" as their games doesn't seem to run any faster despite FPS counter telling them so.
It's not like CPU only, is CPU + new Z77 features :)
Well with this one I can go as high as >14500 in 3Dmark 2k11 with moderate overclocked 7970.
EDIT:
This :)Quote:

what does turbo ratio override partial+4 mean? does this mean locked ivy bridge chips can overclock beyond even their max turbo? I thought locked sandy bridge were limited to their max turbo.
Attachment 125415
Good question, I am curious as well.
Precisely that. I'm always surprised by how little known this fact is, but unlocked sandy bridge CPUs can already be overclocked by up to +4x, which is applied on both min and max turbo states. So will Ivy Bridge too.Quote:

Then there is Petrol, which if priced in gallons/dollars would be roughly $8.00usd/gallon. Double our prices.
The costs don't stop there. Everything you purchase includes in its price a percentage that is directly related to cap-and-trade policy and the additional cost in manufacturing, shipping, and even farming. None of that comes close to the largest cost of cap-and-trade which effects every man, woman, and child. The negative effect such a system has on a nations economic growth.
Yeah, right. Now if you ever get out of your stars and stripes bubble you should understand how astoundingly high quality of life is in Scandinavian countries.
Those prices are inflated to push the population towards public transport instead of owning cars (which are also taxed to around twice their commercial value) and live their life in a more environmentally concious way. A closed superficial mind would think people's money's being stolen, but the revenue from those taxes is used to support the AMAZING services the government provides, and if you ever visited Denmark you would have realised how out-if-this-world that place is. EVERYTHING. IS. PERFECT. There is not one thing that does not work. Not a single soul is left struggling to survive in case of need, there are jobs for everyone-they find it for you-and your work is very well paid: average minimum wage is $23.000 dollars/year(15 in the US), and while the GDP might be lower, we all know how the infamous 1% skews that value for a big part in the US. So yeah, maybe they're not ruling the world's economy, but, to the average person, life there is so much easier to live that nobody cares.
Your argument might work for countries like Italy, Spain, France or Greece. But quality of life in Scandinavian countries is so high that comparing it to the US is like comparing yourself to Mexico.
I was wondering, is Ivy Bridge really hotter or does it just have a more accurate temperature sensor?
Or more inaccurate? :) We can only speculate about that.
Yea I'm really looking forward to some heatsink sensor placed tests where they'd just swap CPUs between Ivy and Sandy and then check temperatures of the sensor placed on the heatsink. Something smells a bit fishy of how the software temperature skyrockets when approaching 4.7GHz clocks, that it would become like 80% hotter ~ twice as hot as Sandy is a bit hard to believe.
At least I'm highly skeptical but I'm like that by nature and never usually take software readings for granted, I usually trust my senses & logical thinking more and the arguments that speaks for software to be inaccurate in this case would be how we're talking about 40C differences here and how Intel that is such a large & advanced company usually doesn't fail that bad in terms of voltage leakage, 10~15C or so maybe (still have to take into account the transition from 45nm to 22nm and the common trend with dieshrinked chips) with the introduction of trigate transistors if these would be behind the cause of higher leakage but like 35-40C? I'm sure Intel's advanced tests/equipment had easily picked that up and the engineers wouldn't have accepted such kind of leakage in first place even if we're talking of more higher clocks here. Therefore I'm personally a bit skeptical about this temp still.
Personally I'd also value if some1 could be doing some "good-cause" experiments and just keep going with aircooling until voltage/clock frequency hits a wall and ignore CPU temp even if it reads like 100C haha, if it continues to clock somewhat despite readings are at like 100C you should also get a bit skeptical.
Why are you assuming the cause of running hotter is higher leakage?
BecauseQuote:

- 40C temp differences only due to different internal designs when going from a 45nm to 22nm process seems to go out of the border what's realistic "goals" using common sense. Maybe if we're talking about entirely different kind of company/resources/devices whatever but not for such a large scale important player in the IT business.
Leakage makes more sense than Intel accepting a design which would be the cause of such a large boost in temp as if it's leakage it would only be a prob at clock frequencies which are way out of their targeted clock range (no big deal if it does handle the targeted clocks good enough)
Well, I do not have a "k" but the 3770 retail sample i have runs 41 (max allowd multi for all cores) x 108 stable @ 1.224V (Load), consumes ~102W (only the CPU under P95 Small FFT) and does so with 2*4GB G.Skill @ 2160. (For now :D )
Temps with HR-02 Macho
@ 700rpm pull. [dead silent] are ~77C average on cores [realtemp 3.7], with PCProbe showing 51C on CPU
@ 1300rpm push the tems are down to ~62C average and PCProbe showing 41C.
Unfortunately, I can not go any higher till I get a higher BCLK out of the Maximus V GENE.
@4GHz the CPU needs 1.09V and consumes ~70W!
The GPU on Ivy Bridge is 2.25 times bigger as the GPU on Sandy Bridge.
http://www.chip-architect.com/news/2...es_Sandys.html
The latest Ivy Bridge die as shown by UBM is larger as previous Ivy bridge
dies. (170 mm2) Somehow the area for the GPU has grown is size. Might
be for better yield but maybe for higher performance.
Hans.
I've never seen such a drastic change between two similar steppings from the same CPU :eek:
Some said that E0 steppings were clocking as high as 5Ghz, but E1 is stuck at 4.5 to 4.7Ghz. Maybe this explains it. :confused:
I don't see how you can say it has high leakage if you haven't seen power consumption figures ov heavily oc'd chips.Quote:

Oh, and Lucid MVP was disabled for both chips.
Has anyone notice this? I thought is was going to be 77 TDP instead of 95 :confused:

Besides, I don't really get the high temp stuff. All those reported high temps are because the chip is really generating a lot of heat or it's just that it can't dissipate a the "little" amount of heat generated fast enough?Quote:

IMHO the CPUs aren't really hotter than Sandy Bridge stuff, it's just that with SB DIE and IHS were soldered togheter while Ivy have just some kind of crappy thermal paste between IHS and DIE.
take off the IHS like we did back in the A64 days should do the trick and solve those "heat issues".
I really wonder why E1 stepping was made such large change to if it went from 77W to 95W, would be quite upsetting as an overclocker if the early rumors of E0 users that 5GHz was reasonably easy to reach on those. Would be very interesting to hear the reason behind the internal change (this is not usually seen on a stepping change) but too bad we're probably never going to.
