We've seen the raw numbers but what about the overclocking potential? How much value does this add to an expensive platform? Equipped with the latest performance motherboards we strapped in an i7 920 under a huge Thermalright heatsink to find out...

Now I wait for results on Foxconn's Bloodrage!

I don't need to use the search function because nobody else has posted this Bit-Tech link. Different sites, different methods, different reviewers.

This is about the 4th thread on this issue? Also that is an Engineering Sample. You will not get that kind of OC with a retail i7 920
How d'you know, d'you own a Core i7? Just because we have more than one thread on the matter doesn't mean this is useless and I haven't followed the rules. Moderators have broken the rules so why don't you go and moan at them for not using the search function.

Rumors in the news state multi and fsb of the non-extreme models have been locked. :(

I know what ES stands for. I just don't see the point in your comments. Completely pointless. The hardware is immature, of course they're going to be reviewing Engineering Samples.

No, he has a completely valid point - if the multi's and FSB's of the retail, none - extreme versions HAVE been locked then your thread is completely pointless, not his post :ohwell:

2.67 GHz (ES) stands for engineering sample... :slap:

If you've been reading the news like I have then you'd know that the multi and fsb of the non-extreme models have been locked.
no they havent thats speculation you have no idea if the FSB and things like 130w limit are even actually true the one thing that is known is that the multi is locked at 20 which it is in those screen shots now please allow me to be the one in this ythread that points someone to more reading material you will find this in the news section of this forum and similar news threads on their respective sites i suggest you start with

toms hardware is the source everyone got that idea from i havent seen any confirmations from other sites......iv seen them say that they heard about it but they have confirmationi didnt even see were toms hardware said they got that info..i mean how would they possibly know? the ES's shouldnt have the thermal limit that would be bad hype and even if it is true i dont see how it would make the i7 hard to hit 4Ghz 130 is quite alot if you think about it...if they oc like the core2's the n you can get a boost without too much voltage meaning you wont hit the limit coolers will also keep the thermal envelope down if you get a good one..i dont doubt the oc ability of i7's its more or less (and has been stated by mutiple sites including intel specs) that the arch is the same as the penryn with a few tweaks im not doubting you im just saying its unconfirmed for the most part as you so willingly said ther ES chips who knows what the main steam will bring us and at that note seeing as the people that have i7's have ES chips nothing will be solid until market

I'd like to see more validation, and I'm interested to see if any more like this pops up. Toms was right about the 48xx series and all it was going to offer so I tend to trust them, but this is a completely different matter. One thing I read about the ES models from Fudzilla is something about the memory multipliers being locked for every model except the extreme edition.

well i know that the main cpu multies are locked and though the mem controller ones might be also i also heard that other sites were getting around 4GHZ stable but they had to use the mobo's mem dividers to lower the QPI speed so hopefully thats the work around

Actually, it's already been confirmed Overspeed protection will not be an issue:
I am to be VERY VERY clear, there is not Overspeed Protection, we have a BIOS setting to bypass the PCU control of Current and Power. On smackover, it is call "CPU VR Current Limit Override", and it will allow you to bypass the thermal and courant limites on the Core i7 920 ans 940. Who ever claim the otherway around did not read the specifications enough :) hehehhe
we have recommanded to the motherboard makers to follow our steps.
So, relax, and don't worry ...

Someone else made a post later in the thread saying that ASUS, MSI, DFI, Gigabyte, and Foxconn have that option. Dunno about any others, though I would be extremely surprised if Evga's didn't have it as well

No, he has a completely valid point
Which is, there are a load of threads where different sites have explained their experiences with the 920? So, isn't having more reviews better as they may give different results/experiences?

Um, what? Did I read that correctly?


kyle2020 said:

What does that mean? if the multiplier and FSB (you mean QPI right?) of the retail, none.

Still have no idea what you mean.

Did you even read the review I posted to?

There we go! :rockout: The fact that other members may find Bit-Tech's insight interesting is another reason as to why I posted it. Usually with new tech people just can't get enough info. I like how more links are being posted on this subject, in this thread.

And the donkey award goes to... ^^^^ :laugh:

Just jumping at people without really showing us that we are ignorant to some fact is just mean. I was under the impression the locked multi was something much less than x20 and that their has been a lot of talk about this that and the other problem with the non-extreme i7.

The entry level chip doesn't look too bad, but now I wonder how well this 45nm process does under the voltage of some of these overclocks.

Ahem.


Please let's get back to discussing on the topic than discussing Zoology. Go watch Animal Planet if Core i7 isn't what interests you in this thread.

That's rather rich don't you think? Don't insult Donkeys either.
That wasn't an insult, it was a joke.

Ahem.

I'm not that corny so sorry if my jokes don't always tickle.

TOPIC:
If you would read beyond I was wondering about voltages. These i7 cores look to require some voltages that degrade 45nm process to hit 4Ghz. Does anyone have information from a reliable source on weither or not these chips can hold up in extended use at voltages pushing 1.4v+?
