Reading helps. If you don't want to read, then you shouldn't be OCing. You'll be amazed at what you can learn and find by typing something like "northwood 2.4C overclock" in the search function of a forum or Google.

yeah. btw pacman and nostyle know their shit. They are both pretty freaking good at this stuff. pr0digal jenius is also a great resource and, as he said, he didnt know what RAM was not too long ago(for shame prod...for shame. I knew what that was since I was 2)

Read up. Ask LOTS of questions(in this case the question unasked really IS the only dumb question when you wind up with a smoked CPU. when in doubt ask questions and NEVER assume anything)

My best advice through my limited experience:
Always know where the CMOS CLEAR jumper is on the mobo. It will save your life and sanity.[color=gold][/color]

One of the best advises concerning overclocking ever

Overclocking is easy but requires a lot of knowledge beforehand, overclocking starts when you start to select your new pc. Also, sometimes it almost looks if overclocking is actually a talent, some people have a feeling for it while others don't, for instance i ussually know prior to buying what my 3dmark scores will be, it's a bit like you personnally know your hardware... difficult to explain but i always let my feelings steer my overclocking and so far it has been spot on.
My oveclocking experiences ranges back to my Pentium 200Mhz which i could overclock to a 233Mhz, man that was a difference, it felt like a totaly new pc back then
From that on i overclocked every pc i owned, and so far (knocks on wood) i haven't been able to wreck anything. cpu's i o'clocked: P1 200, P2 300,Celeron 300, P3 500, Athlon 700, Athlon 1600, Athlon 1800, P4 2.4, Athlon 2400, Athlon 2500 and now my AMD64 3500. quite a list actually when i look back at it, guess i spend too much on pc's and these are only my own systems, not counting friends yet.
Over the years i became apparent that component selection is probably the most important, after that comes finding the time to read up on other people experiences and just basic trial and error.

squall Leonhart

i taught myself to o/c

lol

i can't really get far anyway

unless you count from a 2000+ rating to 2600+

Geminiwave

yeah I love it that my 2800+ goes to 2.5ghz without really any lip.

except for yesterday...I bluescreen my computer. It was the weirdest thing...I was testing out some HD divx video and it was REALLY lagging...it was shocking me because I've never seen the CPU load go to 100% before, so I OCed some and then raised the quality back to maximum...it was GREAT! the CPU load was down to 60% and I was only at 2.35ghz. Then I turned Post Processing back on with the graphics card and BOOM, the second i checked that box it bluescreened. The graphics drivers crashed. Well I figured out that I was REALLY STUPID and forgot to lock the AGP bus. I feel like such an idiot! AHAHAHAAHAH

yeah I just hope I didnt damage anything ^^

oh yeah my biggest scare was making it so my comp didnt post anymore. I finally waited 2 days and turned it on and all I got was a bios bootscreen for the graphics card! it was WEEEIIIIRRRD! thats how I discovered CMOS clear. It fixed everything :-D

sufficed to say, I learned. So as long as you dont BREAK anything, mistakes can be extremely educational.

Thx all! Right now I'm stuffed out with tests and all at school but the moment I got some time, I'll jump straight onto what Zardon said!!! And well, for nostyle I searched onto the net but most of em didn't really correspond to what I wanted..

I know I might annoy some people and I apologise!
Anyways, thx for the help and support!

Geminiwave

I felt no annoyance. Did anyone else?

I think you will find it a bit more difficult to annoy people with OCing questions than anywhere else. People here LOVE to share their knowledge about OCing with the world.

What did you look for? Cuz searching "2.4C northwood overclocking" came with some very interesting results from ExtremeTech and X-Bit labs.

The articles dont' necessarily have to apply to your particular processor. I learned to overclock by reading old articles of overclocking P4 1.6As and applied the knowledge and fundamentals there to my processors. No, you're not going to find an article on just about every processor out there which will guide you by the hand and take you through the process, but you will learn concepts and tips. Usually, if you take a certain class of processors (ie: Northwood C), the information written about it can be applied to the processors of higher clockspeeds (keeping in mind that you may not obtain the same overclocking ability as the lower clocked chips)

Be sure to read your motherboard manual as well. Especially the Advanced Settings section, since that's where you'll be tinkering with if you're going to overclock.

As for annoyance, I only get annoyed with people who ask "is my score too low?" and they haven't showed benchmarks for any other game or utility.

Ahhhh I didn't really think that it would work from old processors to the new ones (and yes I also got a northwood)! Anyways, thx for clearing that up and as I said, as soon as I've finished my horrible german test, I'll start some testing!!!

No_Style

No problem. I'm here to help the people.

I know i wasn't. I enjoy talking about OCing.

BTW....does anybody know about voltages on preshotts (prescotts)? lol...... all i know is that the "threshold" voltage is 1.55v thanx to one of No_Style's threads (thx No_Style). I've been messing around w/my voltages a bit, but i still don't know what clock speed to set what voltage at. Zardon said earlier in this thread that he could do 3.4Ghz on his 3.0C (northwood) on stock voltages. Does anybody know anything about the 3.2E's (prescott) voltages?

__________________

Geminiwave

from what I've seen you can get about 3.4 out of that one too..its basically the same chip OCed a bit. Actually now that I think about it, my friends get 3.5ghz on theirs alright. Using that huge thermalright heatsink(god i love those).

just try it out. Nobody can tell you how far your chip'll go other than you.

__________________

No_Style

Well the max is 1.55 V, so if you feel confident in your cooling, set the voltage to about 1.525 V and start Overclocking and stressing the CPU with PCMark04 or Prime95.

It's true that limits are unknown on a chip to chip basis, but if you can find out the stepping and go poking around on the net, you can probably find information about your particular chip and its expectations. Some people even go as far as finding out what location and whichi week's batch of processors to get to ensure high overclocking. But, the best way to find out the limit is to do what I said of setting the voltage your comfort level and just adjust the clockspeed from there.

Zardon

I overclocked a prescott from 2.8ghz to 3.6 at 1.55volts. I tried higher voltages but even on water the CPU was over 60c. I dont like prescotts. they are far too hot. IMO they are a very bad processor from Intel, certainly not "better" than a northwood. They would have been better slapping on another 512k cache on a NW.

Hopefully in time this will change as they can hit higher clocks than NWs due to deeper pipes. Once they hit 5ghz they will be a great CPU, although I hope you dont need a heatsink the size of your house on it.

For me its - Gallatin - Northwood - Prescott. (and im absolutely loving the mobile Dothan chip, what a wonderful processor!)

No_Style

Dothan greatness. It certainly is a great processor and its development certainly holds the key to dual core greatness. Have you played with a Gallatin? I had to look it up since I wasn't familliar with it.. and it's a Xeon MP chip. How is on the clock/performance scale?

__________________

Zardon

Ah but its not just a MP chip .......Extreme Edition is also a gallatin core no-style.

Which is why so many business users who spent $3000 on a Gallatin based Xeon for a server got really annoyed when intel released the EEs for a fraction of the price (costly to gamers and home market but REALLY cheap to business market). they had to compete with AMD 64 somehow. EEs cant work in a multiprocessor environment though, thats how intel have (sort of) gotten around it to appease the business end.

Zardon

There a picture of my extreme edition (engineering sample) in CPUz on PCIe

tastyweat

I just want AN EE - lol - I like the idea of the 1066 fsb gallatin based chip coming out in oct/nov - but don't know if i can wait that long!

__________________

No_Style

Ahh yes. I keep thinking EEs are Northwoods with more cache. Silly me~ Are the new EEs with 1066 FSB going to be Gallatin based?

__________________

tastyweat

the 1066fsb chips will be Socket 775 based,

the 3.46GHz EE will be Gallatin based

the 3.74GHz EE will be Prescott based (in other words - barbeque time + some!!!)

Geminiwave

I would love to see a place like THG fry an egg on a prescott. That would be so fskin' awesome

__________________

No_Style

Yeah.. I figured they'd be using Prescott for the deeper pipes

__________________

CDsDontBurn

the 2.8 prescotts aren't that great of a processor when it comes to OCing IMO. You're running at 800Mhz FSB @ 2.8Ghz while w/a 3.0E or 3.2E you've got the same 800Mhz FSB, but more head room to OC. you've probably seen this before, but to save you the trouble of looking for it....here's a pic of my best overclock on my 3.2E.



w00t w00t!

Wanna use my prescott?

LMAO sure I'll just "borrow" it for awhile. And then uh...take a trip to canada or something...yeah that works. heh heh heh.

__________________

No_Style

Zardon did 2.8 -> 3.6 = ~800 MHz Overclock
You did 3.2 -> 4.0 = ~800 MHz Overclock

My 2.4B -> 3.2 = ~800 MHz Overclock

I doubt there's more head room, but rather a processor limit due to the fact that we want to stay within the safety range of voltages. I recall that a 3.06 GHz couldn't go very far due to the max of the Northwood Bs and that a 2.4B could easily out overclock it

__________________

pr0digal jenius

3.06 is 533 MHz that has lots to do with it

CDsDontBurn

Didn't somebody already do this w/an Athlon XP chip a while back?

lol.....i didn't think of it like that . I'm a dufus sometimes...lol.

__________________

No_Style

3.06 was also a Northwood B and they couldn't get very far anyways. I think Northwood B's capped around 3.2-3.4(If you're very lucky). My bro's 2.53 GHz is near it's max around the same clockspeed as mine.
