Core i5 650 Reaches 4.70 GHz on Air-Cooling

"Intel's socket LGA-1156 quad-core processors are closely trailed by the Intel's first processors based on the 32 nm manufacturing process: Core i5 and Core i3 "Clarkdale" dual-core processors. Engineering samples of these processors were evaluated as early as Q2 2009, but one of the first attempts to show the processors' overclocking potential using air-cooling was made very recently. Even prior to that, a low-voltage overclocking feat by Coolaler showed how engineering samples didn't particularly struggle reaching clock speeds close to 4.00 GHz with vCore as low as 0.832V. Romanian tech community Lab501. Lab501 community leader "Monstru" tested the overclocking headroom of a Core i5 650 LGA-1156 dual-core processor (engineering sample) with air-cooling."

32 nm from Intel looks to be really good for us. :yepp:

whau, nice !

Thats rad :eek:

Niceeeeeee

Now i need another CPU upgrade :(.

32 nm I7 please.

I'm more interested in a Quad too, not dual core.

Oh my god thats insane, 5ghz benchstable on air?

8K prime doesn't really rock my world :p

I dont get it my E8500 did 4.8 on air stable?

We have nearly 4.8 Ghz i7 920 stable already. On water, though.
But not bad I guess.

4.5 GHz should be easy on air 24/7, with some getting to 5 GHz. Good stuff. My E6600 machine is due for an upgrade when these babies are out.

Just make sure you get a mobo that doesn't have the foxconn socket...

looks like its 17C ish air.
Looks good.

How's the performance? Any Pi screens?

I too can stick my computer outside or in the garage on one of those cold Canadian nights and claim high clocks on "air cooling". The min temp of 20°C means an ambient temp of what? 15°C? 17°C?

what kind of power consumption is found on these 32nm chips? im interested in the 4ghz at .8v

You actually think that 4Ghz is achievable and stable clock with 0.8V?:confused:

i clocked my 860 with only 2 cores to 4.2 like it was nothin but shortly after board would not boot
thank gigabut for using a foxconn socket i counted around 20 pins not making contact or barely lol

:welcome:

Why make such allegations my friend? Why would I deceive readers like that? Simply showing Clarkdale is good enough. Why would I start some rumours that will be put down in 1-2 months if they are not true?

No my friend, I am sorry to set the record straight like this but this is done inside my apartament, with 24 oC temp ambient, a normal retail cooler and a normal retail fan. I am trying to help Kevin to adjust RealTemp for this CPU's, because right now it's obvious the TjMax is a little bit too optimistic. Also I am interested in how Turbo works on this one, how CPU-Z reads the mem latencies and so on. Why the heck would I do that at 15 or 17 oC??? =))

Intel's 32nm process looks absolutely astoneshing, but this is not the first time people are seeing this. Weird enough, I don't remember anybody saying that all those Gulftowns stable at 4,5 on air are done in Siberia, or Canada, or wherever :)


mrcape - patience, we will get there :)

manicdan - well, I haven't seen 0.8 at 4GHz, so this might not be the brightest puppy in the house. But the power consumption with the CPU priming at 4,7 and GTX 295 in idle was something like 260W (roughly).

4.6 - 4.7GHz isnt a problem for latest Clarkdale samples..i had one last month...

also with air cooling

With much better volts even!!! Woot, this 32nm is a killer!!!!

no 32nm quads apparently just these dualies + gulftown :down::(

5.0ghz on water should be sweet... :)

Well I think more is possible on air too, at the moment I am fighting with 190 BCLK, so the frequency and the volts were not the actual limit in the screenshot, but the BCLK. So, who knows. :)

That sucks:down:

Does anyone know when 32nm CPUs are hitting the shelfes?
