Intel Nehalem Absolutely Insane -> 975 ^^

[Lu(ky]

Guys since this is a ES 975 chip does this mean when the retail version comes out it will be the same or better?

[jcool]

There are already some W3520 and W3540 retail D0 chips available that are at least on par with our 975's.
For air or water cooling, get a W3520. I have seen a few prime as high as 4,5Ghz on water, and 220 BCLK is rather easy with them now.
Of course you won't get 5Ghz Pi shots (easily), but what matters in the end is that you can run them just as high for daily use.

0_o I'm pretty sure Intel contracted extra-terrestrials to design this chip. 4ghz on Air is impressive, 5Ghz on air is revolutionary.

Perkam

you still dont got it right perkam
4ghz is pretty much normal, i havent seen a chip that cant run 4g on air, even old c0 chips 4.5 on water seems to be normal as well jcool, i havent seen anybody reaching less than that on water, some even reach it on good air, the newer c0 and the d0 chips need less voltages for it however.

starting at 4.6 there seems to be some weird barrier
that many chips cant surpass stably even with ln2 and huge vcore, must be some transistor limitation or a fundamental design limitation...

worse or the same is more likely, intel has been binning press samples very very well for the past years

pcrinimal, yes, there is something very weird about cpu multipliers, especially with intel cpus... just ask KP and hipro5 about their 780ES chips... the diferences between the multipliers were insane, some clocked ridiculously low compared to others. im pretty sure it has something to do with internal timings and interface buffers that dont work well with certain multipliers. in the end, multipliers are pretty similar to memory dividers, and we all know what vast diferences memory dividers on chipsets had. multipliers seem to be a lot less weird in that regard but it still happens... i dont know if intel can adjust some timings or settings to improve this, but i think they can... but they obviously spend most if not all their time tweaking everything for the stock multipliers, and not higher multipliers...

I've had at least 5 920's that wouldn't do 4Ghz on water, no matter what. Because some CPUs don't like the 21x/20 multipliers, and they don't run high BCLK either

I agree on that, my 975 doesn't seem to like more than ~1,53V Vcore for example
But it does run higher than 4,6

Is this 920 good enough under unfixed Tuniq tower 120 and on µATX board ?



Thank you junior to sent me this chip from Japan

[jcool]

Very nice... looks like it beats my 975 Vcore/clock wise.

I think so

[Pt1t]

Very nice... looks like it beats my 975 Vcore/clock wise.

With same Board / mem / cooling / vcore it does 50Mhz more than my 975xe

[Mpetrosino]

[Scrizz]

very nice
can't w8 to get my i7 setup

[boblemagnifique]

Great 975XE junior-san
i wait your result under LN2

[MrHydes]

congratulations PcCI2iminal, that's awsome frequencies...

and this D0's really are something. my C2D E8600 wouldn't boot no matter

what 5GHz (530*9.5); (600*8.5); (500*10) no way and mine was a

Q822A435 watercooled. Now seeing a true quad core anchieving this kind

of speed on air is just outstanding.

:P

i sent my best D0 to you Thomas,cant wait to see what you can get whit extreme cooling
did you get the new X58A?

Great 975XE junior-san
i wait your result under LN2

hello Bob
Ive tried a bit yesterday and i got 5280MHz with 33x

its not that bad for only 1.48v but more voltage didnt help ,but the funny thing is about the settings ,i can easily get into windows at 5.1GHz with 25 x 204 but i can not boot at 33 x 150(4950MHz) :S, 33 x 133 is just fine but if i try to set on bios 2 or 3MHz more of bclk the SO will not load ...
well ,something is holding me back,i tried to change the memory divider and pci frequency with no luck,of course this chip can do more and i will try again soon

anyway, in the other hand i got good news,this chip is amazing for bclk




bclk @ 235MHz with Tpower X58 and R2E

[crio]

@PcCI2iminal

Man this cpu is doing great.
All of D0 chips seem to have a lot of optential......
BRAVO

[bmilos]

Any word on release date?

[gaidin]

hopefully we see them soon...at least its a new product rather than a stepping so we dont have to wait for existing stocks to run down

[sofos1990]

These results are great PcCI2iminal!!!
5.1ghz getting into windows? this is so sexy
Crio is right D0 chips have a lot of potential, hope the retails chips can do same....

[jcool]

Funny... mine doesn't like the 33x mult.. at all.

[George_o/c]

Hey Criminal what's up man, everything ok with your beloved family ?

Great results on that 975, even if Intel binned this CPU a bit more heavily (not saying that it's true, just a speculation), 5GHz+ on air is pure evil ! I gotta say, I wouldn't be happier or more excited seeing the chip hitting more than 5.6GHz on LN2, I'm pretty darn satisfied with its sick performance on air. Now, I know that it's XtremeSystems here and than subzero cooling plays a rather important role, but watching such sky-high frequencies with these new D0 stepping CPUs on air, makes me horny

Junior, could you perhaps send me a PM with some information regarding the Biostar board you're using, such as availability (can't seem to find it nowhere here in Greece ) and price (you said it's really cheap in comparison with other ones - of course taking into consideration its amazing performance/price ratio) ?

cpus not "liking" 20/21 multis is a board problem
its when the TDP TDC exceeds the programmed value, then the cpu will become unstable and crash, thats a board problem. on BloodRage you can completely cut the tdp and tdc reading for the cpu, dont know about other boards but id be surprised if they dont do it... i think they adjusted this in the more recent bios files though and at least manipulated the tdp tdc reading of the cpu so you can clock higher.

im sure if youd try those cpus again you could hit 4G easily

whats the max 3d stable bclock pcriminal?

[Etihtsarom]

WTF

Simply the word I said when I saw the "All air ^^" comment!

.

Well you at least didn't say it outloud AT WORK like I did. But really, WTF. Jesus Fing Kraist.

[Charles Wirth]

Welcome to the 5Ghz air club, very nice chip.

Now lap the chip and enjoy the extra 100Mhz or so

[Pt1t]

-98° and 1.44V Vcore

[FlanK3r]

relase is about 25.5. i think or so...

Lol. Sorry, that's all I can say to that. I run a DFI UT on my testbed with "set current limit max" option enabled and TDP/TDC limits disabled.
Some 920 CPUs just don't run well using the 20/21x mults, nothing to do with the mobo. If you don't disable TDP and TDC limits, the CPU will come down from 21x to 20x, but that's it - doesn't influence the way a CPU handles the multipliers
