Core i7 920 rev D0 stepping 5 :)

[PcCI2iminal]

^ Yeah I know, this is what im refering to Never seen anyone do that before on a retail chip

retail 920 @ 22x with all cores and if the HT is needed i can enable it
only set Turbo enabled, EIST enabled and you have access to fixed 22x cpu multiplier
enjoy

i dont know who are you and you dont need to know who i am so do not judge things what you dont know.
i dont believe that temp showed by coretemp is the real thing, i just said the new D0 runs a bit colder than the C0

You should know better Sad to see the way this thread goes... The 22x works with any reatail i920 on DFI as wel if you set C6 state.

What board gives the 22 multi on 4 cores?

[PcCI2iminal]

Should this be impressive (see screenshot)? Based on what everyone is making out the D0 to be it should...

The point is, this D0, there is nothing to it. It just creates a false impression that the chip is amazing. Realistically, there is nothing different we are seeing here than with a C0. Max BCLK/QPI clock is either restricted by the CPU or by X58 IOH. Not sure which one, and we won't really know until maybe the B-3 X58 revision is out to put this to the test with its IOH improvements. I believe Saaya had a good theory on QPI limitation being tied to the X58. Only a lower multiplier for QPI will at this point allow higher BCLK speeds and I think this was known about a week after i7 came out. I posted about it way back as well. Some boards do a bit better job, like the DFI, but most will top out (99.9%) at 220MHz-222MHz, or basically 4GHz QPI (8GT/s).

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)

[PcCI2iminal]

What board gives the 22 multi on 4 cores?

Biostar ,I havent tried with RE2 or Gigabyte but when the 22x is enable the bclcok will be limited to 205-207(air or ln2) and it goes unstable and only good for screen.
22x 180-190 range is fine for benching but i dont know if its prime stable but its better to use the same multiplier for all cores -> 20x

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.

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 he is talking about everything but that

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

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.

So am i, should not have added the 22x comment

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

[okorop]

yeah man, but he's using a Biostar. All of that info in the first post would have been significant no? Sorry man, but this shouyld be in the Extreme News section....not the regular, retail, blue collar section where people have to work together to find a way to decipher all of the bs that comes with this hobby.

I agree with you

I should not have said anything about the 22x multi or DFI.

Me point is that you should know the TS is a respected member that brought a lot of good info to all of us and never had or wil have the intention to give false information.

All we need is pure details, not just a screenshot that basically tells everyone "Hey look what I can do". I meant no disrespect loco; I shoot from the hip, and sometimes it stings but my intentions are well meant.

it was easy to reached the max bclock and the max clock but what i showed its not enough to post in Xtreme section, not since the C0 reached the same clock with same voltage or lower and some really good chips 4.8GHz or more.
and i can not post on news section,not when im not sure about everything,the sensor is off for sure and the chip is really good for air,thats what i know

And PcCriminal, I'm not trying to lamb-baste you, or call you out on bs, I'm just reacting to the crap loads of posts in other forums news sections with hundreds of noobs arguing over a chip that will not, in the state that you have, be available to the public.

im fine man and i dont want to start a fight
i dont have much time to test and everything what i know about the temp i posted here(post #25)

the sensor is off i think or the real temp is the higher showed on coretemp ->26c

depends ,some good i920 C0 can run with high clocks and low voltage and some not but will be nice if all these new D0 will run like that ES

http://www.xtremesystems.org/forums/...3&postcount=25

and the new rev D0 will hit the streets at end of march and who wants to upgrade to lga1366 is better to wait and buy the fresh rev D0,of course if it will be not overpriced
and who wants to upgrade from C0 to D0 is better to wait and see what the new retail D0 can really do

[runmc]

I say let's have some respect for PcCI2iminal. No more thread crapping please.

[zlojack]

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

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.

I am eager to see more D0 results. Thanks for keeping us up2date, PCC.

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.

WOW! if the retails oc like this then it may be worth swapping out the i7 for the revision
