My Northwood so far at 2.75ghz EDIT: Back to 2.7 to be safe.

I might experiment later on when I decide to drop $80 for the MCX478. But I really don't want that damn Delta on there 😀

That said, I think 1.75 is OK. As long as the temperatures are kept in line, you shouldn't have any trouble. 10% is usually the recommended max for overvolting (which would be 1.65v) but I don't why (so long as the temperatures are kept in check) 1.75v would make any difference. The chip will be past its time before it would die from a little extra voltage. 🙂
 
from my basic knowledge of electronics, i believe the p4 was designed to be used on a certain voltage (1.5V), if you go higher than that, you might make the transistors to work better, but since those transistors have limitations, which must be REALLY low at such an incredibly small process, you can cause a transistor to break. Compare it with putting 15V on a 10V capacitor, it might last a bit, but it could break down.

once one transistor breaks, you might see crashes when they get accessed, or, if it's at a critical place, it can stop working.

hope that explains something, and i also hope i didn't tell any nonsense (final in 2 weeks, so better not be)

<< Great OC. Thanks for sharing your information with everyone. It really helps the community. >>



Thanks I hope it does. I also started another thread with just the facts none of the hype 🙂

Pabster, it's not an issue of heat, but of voltage. As the transistors become smaller and smaller, their ability to handle voltage decreases accordingly. Individual transistors (or banks of transistors) could fail. Not only that, but the P4's cool running nature is in part due to clock gating. Clock gating is where portions of the chip are shut down to maintain overall temperature. This is fine when the chip is idling, but under high load it can be detrimental when the voltage is above spec.
 
Texmaster,

Why don't you save that HUGE (700KB+) bmp as a Gif file? Should be 30 KB or so - even MsPaint supports saving as Gif.

Thanks for the technical explanation, I already understand that 😀 I still maintain the chip will be outdated and no longer in use before any damage appears from giving it some extra voltage. YMMV 🙂
 
Well......I tinkered today and got my 2.2 Northy up to 2.6 stable. Don't have a place to host pics anymore, but here's the text of it.......

P4 2.2Ghz Northwood
(O/C @ 2.6 @ 1.6V)
Abit TH7II-RAID
1024mb of Samsung PC800
MCX478 H/S W Delta


WCUPID shows:
Internal clock @ 2618.43
System Clock @ 119.02
System Bus @ 476.08
Multiplier @ 22

Sandra:
CPU Arithmetic @
ALU 4967
FPU @ 1367/3200

CPU Multimedia @
Integer 10407
Floating point 12711

I'll probably be able to post the results to a site and link to them later this PM or tomorrow AM........as soon as a friend of mine hets back home.

I'm pretty happy with the results, only needed 1.6V overclock of the Voltage so perhaps the TH7II is a difference.......

 
Why is everyone impressed with the OC? Its on a .13 process and has a low IPC. Whats so special? It was made for high mhz lower IPC per mhz. Nothing special about the mhz with a pipeline that long and a low IPC. Its just mhz(rpm's) NOT POWER.

In a way you're right. If there was a 2.2GHz Athlon that overclocked to 2.7GHz, I'd definitely say that would be more impressive. But a 2.2GHz NW @ 2.7GHz is almost a 23% overclock, and that ain't bad at all. That's the max for a safe and stably running NW, but still, nothing to sneeze at.
 
I've got a 1ghz that OC's to 1.5ghz. Thats a 50% oc. Does that count? 😉

That's the best overclocking chip on the market most likely (1GHz AXIA's). But that's an old T-bird, we're comparing the AXP's to the NW's here. 🙂

That's an awesome pic. Helluva nice HS/F combo. How loud is it? 😀

Thanks!

Really, its not much louder than a 60mm black delta. and when I put my case back on with the noise dampeners, I can't tell the difference.

Hey.........did I or most say anything about it being SO SPECIAL or SO GREAT??????? It's a brand new chip and people want to know how it does exactly how they do with each new chip that debuts!😉 Yes, with the new proccess and long pipeline, it should O/C very well, and it does. You're also correct, it's not "power"......it's merely mhz, but, this also intrests people since it's new just as O/C'ing video cards, memory, or anything else!😉 If it doesn't intrest you, doesn't impress you in any way, shape, or form.........easy fix! Pass over the thread and don't worry about it but there are those whom do want to know!😉
 
If it bothers you so much by what I say just skip down to the next thread. All I was doing was making a statement. If you don't like it. Then don't read it. BTW I am interested or I wouldn't have even read the thread. But, no I am not surprised to impressed.

1631 Mflops at 2.7Ghz. How pitiful. Even the Athlon 1.33 beats that at 1848.
If you are having trouble interpreting the sandra results, note that there are two numbers for the PIV mflops seperated by a slash. The first number is the true mflops, the second measure is SSE2 optimization. Sandra does not do this for AMD's SSE and 3Dnow, only reporting the true raw speed of the FPU. It the first number that matters for the PIV results.

LOL! Apparently you're the one whom is bothered, or why make a statement such as yours in the first place!😉 If this was a thread stating the B/M's and O/C of the new 2000+........I'm willing to bet your comments would have been different.......😉 You're the one whom had to comment on how "unimpressive" the P4 O/C was therefore you are the one whom started the thread crap!:Q I'm sure this is beyond your comprehension though so my words will be wasted on you......🙁 Just understand that there are people whom are interested in the results simpley because it is a new item............I'm sorry you're not, but, that's no reason to crap on a thread of those whom are!😉

Have A Nice Day!🙂
 
I am not impressed by the performance, just the good OC percent and high GHz. I'm happy he is sharing so other Northwood owners have some guidelines. I'm an AMD person myself.

Any SETI numbers for these OCed Northwoods? I would be interested to know how long a work unit will take on the latest/greatest Intel processor.

LOL Take any benchmarking article about the 2.2 northwood and it beat even the xp2000+ in the majority of tests. And I'm 500mhz over that.

I know you are new here but this thread was started to give people a look at how normal guys do with the new processor.

It says a lot about the people here that there have been no flames until your pathetic ass showed up.

Get lost little boy, we are having fun here 🙂

Hmmm, but what of those whom now or in the future buy according to SSE2 optimised software/programs.........??? Could it then be said that the Athlon would not be a viable choice? Or what of when AMD begins utilizing SSE2???? If it is not up to par with Intel's SSE2 B/M's will it still be unfair???? What of a seperate B/M which only measures 3Dnow?????? Would the Athlon be a far supeior choice because of that B/M?????

It's so simple to cut something down because of prejudice or disdain for the product.........why not instead applaud it for what it has acheived???? I also own a few Athlon's and B/M them and compare those also. Is it so hard to see them both positively and not cut down one or the other merely because of blind prejudice??????😉

Even mentioning this is pretty ridiculous if all you can say is that a NW @ 2.2GHz wins 9 benchmarks, loses 7, and ties 2 to the 2000+. Or even worse, the NW @ 2.2GHz winning 5 benchmark tests, losing 6, and tying one to the 2000+.

In a very real way, there's no difference between these CPU's, it's so microscopic that hardware sites have to run gaming tests at ridiculously low resolutions to find a difference. In the real world the 2000+ and 2.2A are no different performance wise. Price wise is a different story. 😉

OK. When did I say I was bothered? Where did I crap? Also when did I say that the oc was not a good oc? When did I say anything about a XP overclock? When did I say I wasn't interested? If I wasn't interested, would I have even read the thread? I said I wasn't impressed by it because look at the white paper of the P4. The P4 was built for all out mhz. Its not no surprise at ALL that the P4 ran at that mhz. Thats is all it was made for. I'm so sorry that you are getting so upset with a post I made.

LOL! It's clear to see your prejudice in your statement.............😉 It's fine that you like AMD but why come into a thread concerning a new Intel product and belittle it???? Don't even say you never meant that...........the original two statements are clear that you mena to imply that your 1Ghz Athlon is a much better product. That wasn't the subject in this thread and I and many others whom can find a way to appreciate both AMD & Intel fail to see the point of coming into a thread concerning the Northwood and saying that your 1Ghz is better because that's exactly what you did!

Like I said, your prejudice against Intel is clear here and in other threads and it's just puzzling as to why persons such as yourself feel the need to attempt to belittle/corrupt any thread concerning an Intel product!😉

Sorry Tex to get into this in your thread........I just find it sad that there can't be a single thread concerning one product or the other without it being crapped upon............🙁
