[citation][nom]xantech22[/nom]ummm...didn't he mention the use liquid nitrogen? if not, im pretty sure that's what they used otherwise you're right[/citation]
Nope. The AMD guys probably used liquid helium, but there's no info much for the 7.1GHz OC.
However, LimitTeam didn't reveal any specifics in regards to cooling during the overclocking process.

[citation][nom]mlcloud[/nom]Why can't some of these folks give us some FPS benchmarks for fun? [/citation]

Wouldn't be much different from the stock speeds. Most games are GPU dependant, hence why the Core i7 stock doesn't grab much extra performance over a dual core or triple core AMD. The games benchmarks would just bottlneck in the GPU.
 
[citation][nom]icebain[/nom]anyone notice in CPU-Z it says AM2+ socket when the article says they used DDR3? Am I missing something?[/citation]
Yes, you didn't read the other side of the validation page where it says DDR3.
 
The 7.1 GHz Phenom II will still kick the 8.1 GHz Pentium 4's butt. Just because of P4's deeper pipelines. It's inefficient.

Just the thought that the ALU is running at 16.2 GHz on that chip is just like WTF?!?! Since Pentium 4's ALU always runs twice the speed of the CPU which is just insane!
 
all these clocks and cores are great, but im really exited about the new steps being taken in multi-core processing, ive heard some babble talk about sub-cores within cores being the next gen philosophy so when we finally get 1000 or so relative core processors we might have true AI on our hands with cpu's writing and designing efficient software and even more efficient hardware? just wondering how far away are we, any thoughts?

i still want an x3 720 BE, should tie me over for awhile . .
 
[citation][nom]davekozy[/nom]I think power (heat) increases linearly with frequency and exponentially with voltage. Pentium extreme 965 was 3.73 GHz stock and 570 and 670 were 3.8 GHz. They were the highest stock speeds as far as I know. The 570 and 670 were only single core but the extreme 965 was dual core.[/citation]
Correct but voltage has to be increased as frequency increases to satisfy the switching requirements of the transistor gates, so technically you're right, but also wrong at high frequency.

It can't be done, according for current knowledge in computability theory.
 
CPU overclocking records are getting kinda boring. SSDD, lets see some GPU overclocking contests. I wanna see some LN2 coold GPU's. single, dual gpu cards, dual dual gpu cards, quad dual gpu cards, whatever. Then run some games & Cuda/OpenCL etc. apps.
 
[citation][nom]idisarmu[/nom]7.1ghz Is very impressive in my opinion.I hope that 28nm cpus will get us to 3.6-3.8ghz stock and 4.2-4.6ghz overclocked.... I'm just dreaming though.[/citation]
[citation][nom]eklipz330[/nom]that's not happening, as frequency goes up, heat increases exponentially[/citation]
It isn't entirely impossible though. We already have a mainstream CPU clocked at 3.33 ghz, and stated by another poster that the Pentium D 960/965 was at 3.6/3.73 (cannot remember exact numbers). Perhaps the 32nm or 28nm fab will be the final push to give us mainstream 3.5ghz+ chips (with respect to heat dissipation that is).
 
Not really impressed by these world record overclockers unless there's a major distinction between totally enclosed case overclocking and open case overclocking. I'd be impressed if the record was done in a normal mid-tower case where all cooling components are within the case. Otherwise all we have is a motherboard plopped on a table where anything can happen. A room size cooling system to support a motherboard the size of a checker board is nothing short of an old UNIVAC. For now pretty cheap and gimmicky PR for both AMD and Intel.
 
I could overclock it faster, but I don't feel like using a $15K helium cryostat and a vacuum chamber for that purpose. At 4.1K, it might even superconduct.
 
i7's run waaaaaay to hot when overclocked for me to buy one, im betting on the 25 degree celcius lower OC temps on the phenom 2's will go along way in terms of LONGEVITY and RELIABILITY of processor and the overclock aswell,

once you go past stock voltage, sense and reason is thrown out the window.
people can talk all the trash they want about it being designed for it or some blather of the sort, more heat breaks things down faster, alot faster, period.
its like some of these wannabe motorheads saying they are gonna overboost thier turbo car from 10psi to 40psi on a stock motor and saying oh yeah i got 200,000 miles out of it, Never ever gonna happen. even with the best tune. as heat goes up thermal wear and breakdown occurs exponentially. im quite sure this is definitly true with processors.

when it comes to games the i7's OC vs phenom 2's OC are virtually the same when it comes to fps, they perform almost identically. honestly the i7's are benchmark queens, unless your encoding video all day you wont see the memory architechture gains displayed.

id say less than 1% of people who run PC's are video editors on the level that will ever see those 2 second compiling advantages or whatever,

yes Im a film student.
 
I can reach 4.2 Ghz stable OC after about 3 hours tweaking the system
 
[citation][nom]Pei-chen[/nom]Can it play Crysis? (Or GTA IV) I’d love to have a 10GHz 16 core i7 to run GTA IV though.[/citation]

Both of those games are ~5 years old...

My old ass Pentium4 3.2GHz and a Geforce 8600GT can play it at moderate settings......
