Core i7 920 rev D0 stepping 5 :)

[dejanh]

What board gives the 22 multi on 4 cores?

Technically, all should if the rest of the cores are idle i.e. powered down due to C-state transitions. I have never managed to recreate this on the R2E though with 4 i7 940s unless I physically disable all but one core.

of course im not sure but i believe the max bclock is restricted by the mobo,bios maybe ,i never reached more than 222bclock with any cpu and i tried to push it hard with tons of Core i7(retail and ES) but I only used three good boards(Tpower ,RE2 and Gigabyte Extreme)

I'm quite sure that it's the X58 chipset. My second bet is the CPU itself, but I find this a bit less likely now. Keep in mind that we are talking about many different motherboards, and many different chips, and 99.9% have the same BCLK limit, and the only thing that is consistently common between them is the X58 chipset.

I would not be surprised if the new B-3 revision of X58 allowed higher BCLK though we won't know until sometime after mid-May I think.

D0 is supposed to bring a few things to the table:

1) More consistent overclocks (no large variations in overclocking ability like with C0 chips where some can do only 3.8GHz and others can do 4.6GHz).
2) Slightly lower voltages for same clocks.
3) More balanced temperatures (related to voltages above).

Generally, D0 will not do much for improving the overclocking ability unless D0 was based on the best of the best of C0 in which case most D0 will clock better than an average C0.

i think the Intel is working for improving the overclocking ability , things have changed since AMD reached more than 6Ghz with their cheap quad

What this implies then is that in order to regain its throne as the king of OC Intel will blantantly EOL their 940 and 965 chips to replace them with much better i7 chips based off of D0 stepping. If they do that, I will make them replace my chip if it's the last thing I do.

Not to even mention that would be the biggest show of disrespect for the consumer I have ever seen.

I somehow find this outcome very hard to believe. I would have no issue with them keeping the specs and names on the 940/965 and improving the OC ability slightly compared to C0, but a new chip with new upper multiplier limit is just bull.

Dude, how long have you been in this habit of overclocking? You're hilarious. Oh, you owe PcCI2Iminal an apology for crapping his thread. My God, since when did a guy have to apologize for showing pre-released hardware on XS. Y'all need to take a chill pill and be more appreciative of the fact that you belong in a forum where members get their hands on the new toys far more consistently than other forums.

I agree that they owe PcCI2Iminal an apology, wow . He always posts good info and is a good guy. If you don't like what he posts, keep it to yourself. This is XS not podunk club clockers (PCC).

Good info PcCI2Iminal, I put off buying until I could see how much difference the DO would make, thanks.

The Core i7 950 will replace the current 940 so the 975 due in may with an higher multiplier. So what i gather from your post is that intel should stick with i7 forever so your system is top for the next 3 yrs . I bought a opty 3 yrs ago and the next 6 month conroe came out and beat the pants off my AMD. This is how the technology market works, if you don't like it go back to your 486. If you wanna stay on top then be prepare to spend money every 3 month or so.

No this is not how technology works. This is apparently how technology works in the NVIDIA and Intel world where products go EOL before they decently hit the market. But, you are entitled to your opinion. Clearly either you are a brainless consumer or you do not work for your money. Otherwise this moot point would definitely concern you. I'm also sure you'd be singing a different tune had you bought a 965 or something for a grand and will soon be able to put it where the sun don't shine. But its all technology mate

Anyways, since this thread has turned into a mess of babies crying for apologies I don't think there is anything more to say. Criminal was never my target and I do still disagree with posting results showing temps and such when they are clearly not correct. That fact won't change. In terms of how D0 will do, we'll all know once it's out won't we. Props to him on getting his hands on the ES chips.

[PcCI2iminal]

thanks for all of you guys for the nice words but i think no need any kind of apologies,i respect his point and thats all
i dont care if the sensor is off but the 4640Mhz screen is real and i got it so easy ,all what i want is a good chip for overclocking and that D0 is one of the best core i7 in my collection
we can not forget where we are,here is the Xtreme Systems and we are not hardware makers ,we only make dreams and world records and thats why i posted that information only here(and in my blog :P)

Yeah i bet ! I have not seen much C0's do 4600 air. Mine can only do 4050 on those volts. I really hope those retail D0's can hit those speeds. I would like 4.0 GHz @ 1.2v :P nice low power setup. i now need 1.35v for 3.8 :S

Were you around when the G0 65nm hit? All of the sudden Q6600's hit 3.6GHz easily instead of 3.1-3.2GHz (on the B3's), and temps were much lower. I didn't hear anybody screaming for Intel to replace their chip then. If you want the new stuff sell what you have and go get the new one.

And then when the E0 stepping hit on 45nm C2D/Q all of the sudden much less vcore was needed (as opposed to C0), and temps were a good bit lower. Also, the QX9650 was pretty much EOL (except for those using LN2) at that point as the Q9650 E0 overclocked better and ran cooler w/ less voltage at a much lower price point.

History has repeated itself once again (it seems anyway...we still need to see more retail results). Early adopters always go through this...this is the price of being on the bleeding edge. If you don't want buyers remorse don't buy the most expensive chips right when they come out, and never buy new Extreme chips. I held off on I7 for this very reason. You can still fetch a pretty penny for almost any Extreme CPU on eBay, but the value on forums like this always drops off steeply.

Would you rather Intel did nothing to improve upon their design? This is not some radical improvement. These chips aren't running 5GHz 24/7 on air or anything. So far it looks like the C2D/Q C0->E0 jump...better temps and a tad bit more speed (~100MHz).

It seems everyone else would like the i7 to run cooler and faster...why not you? Personally, I don't think having chips that run 90*C+ is acceptable, so this is a welcomed and needed improvement.


I don't think the D0 chips have a higher multiplier limit than C0. From what I've seen in this thread it just matters if your mobo has the support and you set the BIOS settings right. The 920 has the 22x w/ Turbo, so its in there...just a matter of having the right board/settings to enable it.

Technically, all should if the rest of the cores are idle i.e. powered down due to C-state transitions. I have never managed to recreate this on the R2E though with 4 i7 940s unless I physically disable all but one core.

The same is true for my EVGA X58 and my former GA-X58-UD5. If I disable three cores in bios, I get 22 with Turbo on.

I just thought they'd figured out a way to trick it into 22x multithreaded which is why I asked but I see that's not the case.

but why you need multi threaded 22x?22x is only good for single thread ,the others 3 cores will work at 20x and you need lots of vcore just to get the 22x core stable with high bclock

Well, if I could have a 22 multi with a multithreaded workload on an i7 920 I'd take it

But I know it's not possible. What I'm confused about is, I was under the impression that you get 22 ,(and effectively) 0,0,0 or 21,21,21,21 with turbo on.

At least, on the two boards I've owned, the only way to see 22 is to turn off 3 cores.

Maybe I'm not understanding it properly. I've always said I have just enough knowledge to be dangerous, but not quite enough to know what I'm doing
