All of this is pure BS.
Overclocking is awesome, and will stay this way.

That was a good interview with you in the overclocker Francois.

Thanks!
I don t understand why people would spread such untrue information. I think we need a BS meter attached to the profile

I think it's a matter of nothing else to do, and partly do to the many rumors of poor overclocking from months past

I won't be able to get Nahelem at launch but I am eagerly awaiting results after lauch

I did chat with the best overclockers in the world ... some are here, and when they release what they can do, you ll see that Core i7 and Core 2 use the same process technology: 45nm High K ... the magic is in the High K for overclocking!!!

that is excellent to know.

Is the multi on i920/i940 unlocked downwards?

Cheers,

That's great to know that you guys are taking care of the enthusiasts too. BTW thanks for coming and getting involved in the community

Anyone know what the price difference is between the Asus P6T vs Rampage Extreme II? I'm hoping the P6T doesn't run in the $400's.

No, both of those were with the multi knocked down to 20. Base clock goes up to 200 easily and you can probably guess what the most I got out of it was.

As for comparisons to Core2 Quads, they are both 45nm with High-K gates and they clock about as well as each other the unanswered question for me is the performance improvement from the Ci7 architecture, SMT & Tri Channel memory.

mbs in stock but way way way overpriced

dont think ill bother yet
also they dont have chips yet so whats the point

You'll only see big performance improvements (ie. 10% or greater) with Nehalem if you run software that makes proper use of 4 or more cores vs. current chips. This is what some have been alluding to by saying it won't be that great vs. current chips for gaming, performance will probably be almost equal on a per clock basis. The only games where this might not be true are UE3 based games since that engine supposedly is the most rigorously multi-threaded out there ATM. Allen Wake should benefit quite a bit too when being ran on Nehalem vs. current quad core chips. Since over clocks aren't all that much better either if you've currently got a quad or even dual core chip at or over 3Ghz Nehalem probably won't be worth it for you're average gamer until it gets (much) cheaper and/or agressively multi threaded software becomes common place.

Where Nehalem will truly shine is server workloads and heavy duty scientific number crunching. Its really meant for that market, it just happens to perform well on desktop apps/games too, much like K8 was in its prime several years ago.

I have just managed 3,9 GHz with a Core i7 920 ES (3,8 GHz without Turbo, both settings prime95 stable, screenshots below) and Asus P6T Deluxe. 1,35 V Vcore was enough for 3,8 GHz, about 1,41 V for 3,9 GHz. Not bad for basic Bloomfield :-). Other settings:

QPI: 1,4 V
IOH: 1,35 V
ICH: 1,4 V
speedstep, turbo: on (for 3,9 GHz), off (for 3,8 Ghz)
virtualization, C1E: off
spread spectrum: off
skew: auto

memory (qimonda ddr3-1066, cl7, 1,5 V): trichannel, about 1200 MHz, 9-9-9 (8-8-8 was stable tool), 1,64 V, 3N for sure

Core i7 965 XE only 3886 via multiplier :-(

[Chri$ch]

Your prime Screen is without Turbo-Mode?! 185x20,5?

Btw CPU-Z show 1.43v for 3.8Ghz...

Can you run prime with correct voltage and a little bit longer?

So do I, at least till more games are programmed to use more than one core. Is there any word on if our 775 heatsinks could work with 1366 given new mounting equipment.

Well, considering that all games coming to PC now are pretty much multi platform, ps3/xbox360/pc, games have not tested current hardware much, except for a few titles like STALKER CS, and CRYSIS, other than those 2 pc exclusives, all other games are console ports with some "enhancements", xbox 360 and ps3 will see life into 2010, ps3 should be staying till 2012 from what i have heard, so you can imagine games and graphics cannot change much, plus we have hit a wall in graphics somewhat, where there is not much to improve, maybe ways to render faster and better ways to optimize games and such..... My point being, dont expect much games to come out takin advantage of 8 threads, there is only a handful of apps that take advantage of more than 2 cores, yet alone games. Most games are still single threaded.

and what were your max temps on air ? what are the max temps for the i7 920 ?

That's all? ... OOPS!

[Ufon]

freshy: Temperatures on this screenshot are with Thermalright Ultra-120 eXtreme.

Chri$ch: Maybe if I find some time. Creating review of all three Bloomfields is my primary task, overclocking is only fun and additional info for our readers.

High K as in this High K?

Food for thought.

You're right, my mistake.
Edit: no, it has to be error somewhere else - I have checked this, EIST off, Turbo off, 20 × 190 = 3800 MHz, I have no explanation for this 1/2 ratio.

Is it enough?

(with the 3,9 GHz turbo and 1,42 V I ran another 40 minutes, but as I said I have to make conventional tests for review)


Btw, 4086 GHz in Turbo mode (still with air cooling):

[aussie-revhead]

Ufon - can you tell me if this fella will give much of a gain in 3D06/vantage ?

[freshy]

Ufon the reason i ask about the temps is on that link of yours real temp says 89,89,85,85 and core temp says 92,92,85, 86 , im used to with my quad max temps when folding are 56c max, so does core i7 run that hot or those temps wrong ?

also what is the intel recommended max temps for the core i7 920 ?
