Umm, let me see a 920 variant of D0 from retail do that, and I might be sad.

 

[chizow]

lol damn that's nice at 1.29V, although I have to temper my expectations a bit given that's a 975 ES and you're on water.

I'll probably wait for the D0 now though haha, MicroCenter basically sold out all of their old C0 stock on that April 1st sale, so I'm betting their next pallette is going to be D0. Hopefully. And hopefully before the weekend heh. Still waiting on RAM to come in anyways, Newegg has been skimping and using bankrupt DHL lately, adds 1-2 days to deliv time.

I realize this doesn't address your question, because I have no idea, but what do you do with this stuff when you get sick of it? Seems like you get a lot of new things passing through, do you just ebay it afterwards? Back when I was running a tech site, I used to amass a closet full of this stuff then give it all away. It wasn't exactly efficient.

No, he has more $ than brains.

Nope, not even a little bit. Not gillbot priced, no care.

that is NOT representative of typical results

wow nice.. is that linpack stable tho?

1.25 testing right now:

Meh i'll guess i have to take her down lower. :\ i'll do that later tho.

stable as a rock, it has never hardware crashed in 5 months. linpack and prime tested, plus countless overnight runs of x264 encoding. it can probably go lower but im lazy.

 

[chizow]

Sheesh lol, although Dmens hand-picked+1 is even less applicable to reality. I'll try my best to hold out now for a D0 as I'd be happy with 3.8-4.0GHz on an i7 920 with 1.3V or less. From what I've seen its possible to hit those speeds on a C0, but only with close to 1.4V.

 

[JAG87]

I like how everyone is drawing conclusions about the D0 revision from an intensely binned 3.33G (actually 3.5G with Turbo) engineering sample Core i7 Extreme. I'm sure all retail 920 D0s are going to clock just as well... /sarcasm.

Seriously there is a reason some CPUs end up as Extreme and some do not. Intel doesn't have a monkey that picks the ones with the shiniest IHS, only a handful of chips become Extreme Edition and for a good reason.

You're getting your hopes up, but fact is D0 is only a packaging revision, and not a die revision. This isn't what B3 to G0 was believe me, D0 won't make you sad it will make you disappointed because you waited so friggen long to get an i7.

Aigo's and dmens's chips are not the standard, they are the exception.

 

[dmens]

D0 is an all-layer stepping, which is a die revision, i guess. the latter is not the term i would use.

also, a packaging revision (pin swap?) is even more drastic and costly than a die revision and is to be avoided at all costs.

I've already tempered my expectations, but honestly, I'm not sure what past experiences you've had with semiconductors and ICs have led you to that conclusion.

My take on it is that engineers and manufacturer's goal is to produce the best possible chip, period. They're not telling electrons to work 75% as hard on one wafer and Extreme overtime on another, or to mail it in once they finish enough of the L3 to meet whatever chip bin they're shooting for, or letting their monkey go home early once its picked enough shiny heat spreaders.

Sure there's going to be binning and chip modification to meet market segment demands, but one of the fundamental principals in overclocking is that demand is going to be very low on the high-end parts with a supply that should theoretically all be the same until validated and binned otherwise. I'm clearly hedging my bets that there's more "high-end" parts that could be sold as such, but are down-binned to meet demand.

As for being disappointed in waiting, I highly doubt it as I only impulse bought the C0 yesterday when MicroCenter twisted my arm at $199. I think I'd certainly be more disappointed if I were impatient and ran this C0, only to find D0s were consistently hitting higher clocks at lower voltages. Waiting a few days for a shot at a D0 shouldn't be a problem for me, especially since Newegg hasn't delivered my RAM yet. Certainly not disappointed in that regard either, as the differences in price compared to launch is less than half of what it was.

Sounds like a pretty significant revision, thanks for the info!

but my conclusions are coming from 2 ES samples.

C0/C1 ES
vs.
D0 ES.

And if the models behave simular, then i have great expitations on the D0.

Did you forget my 965 was also an ES?

don't forget all the work that went into telling you which clocks to delay lol

lol true true

Less chit-chat, more westmere. :laugh:

Good job guys, I haven't read a report yet on end-user experience with D0 that isn't flattering of your hardwork.

And thanks for taking the time to set some misinformations here straight for the record. Always value-add. :thumbsup:

 

[harbin]

Just want to know, is my C0 920 LinX 20 run @4.0g with 1.19V Vcore any good comparing with your D0 result? Or I need do more to approve D0 is nothing new?

 

[Soccerman06]

My C0 920 reached 3.8ghz at stock voltage and hsf... I left the window open that night and the room was like 0F so I figured I might as well try and I kept the cpu stable for 3 hours until the room warmed up and it breached 85C.

I think I got a cherry.

i am a hardware junkie.

And on times i give out my stuff to family after i get bored of it, or pass it to my friends.

Im benching her now..

Its scary it holds linpack with HT ON @ 4040mhz @ 1.37Vcore.

D0 is looking good, i'll push her more later when i have some more time that free's up.

I can has friend?

lol. Good job getting it to 4GHz on 1.25V. Look forward to hearing more.

105% WOT yesterday! (I drive engineers crazy talking this stuff but of course they MUST run things in.) :laugh:

Why aren't you using a chiller to drop your loop temps to ambient dewpoint yet?

lol

 

[Acanthus]

I didnt know the I7s were hitting 4.2ish on water with reasonable volts...

With DDR3 coming down... I just need a reasonable Asus board with voltage dampening.

Well we know D0 is something new, so your attempting to claim it is not is simply pointless attempts at thread crapping.

No single C0 result is representative of the experience of the vast majority of C0 owners (so what if you got 1.19V with a C0 if no one else on the planet did?) just as Aigo's results can't be expected to be representative of D0 results until we get more D0 owners chiming in on their experience.

But thus far Aigo's results are in-line with just about everyone else's that has been leaked as read across the various forums, there is nothing here that is outlier'ish.

Exactly. There are certainly C0s that clock well at low voltages, but they've been pretty clearly shown as the exceptions to the rule amongst all current sampling of C0 parts. With D0s, we're trying to establish if the new samples are in fact the new rule, and not the exception.

Most i7's will allow you to severly undervolt them at STOCK speeds, but YMMV when you start getting above 3.0-3.2ghz. In my experience, once you get over 3.2 and start hitting 3.6, your voltage needs go up considerably. There always are "cherry" chips that can do amazing things, but thats the exception, not the rule. Oftentimes these "4.4ghz stable" chips really aren't that stable either; not saying some are not, but many people have different ideas of what this actually means.

 

[IanY]

I wanna see 4.5 Ghz. Low volts is nice and all. But I don't believe I've seen any C0s water cooled at 4.5 Ghz. The instance at XS was 4.4 Ghz. Anyway, I think NordicHardware did a C0 at 4.1 Ghz at 1.25 volts or 1.225 volts. Still, doesn't impress me.

Get it to 4.5 Ghz and over (without touching the chiller) and I'll be very impressed and I'll order a 965EE immediately upon release. Otherwise, it overclocks to the same extent as C0, so what's the point?

You mean 4.5g stable on water? I believe that is very difficult if not possible at all. On the other hand, I did get my C0 920 booted into windows on air, but it is not prime stable at all.

Offtopic, Iany is a really good friend of mine i dragged onto this forum.

i didnt have time for testing, this was what i took last night,

i'll test it later today when i get back from work.

I think you are the one who may be wrong.

Even woldfale C1 ---> E0 made a big difference.
