Overclocking my P4 northwood 2.4

Hi i'm a new guy atound these parts and was lookinf for some help from those far greater than I. My specs are in my sig. I'm using a 2.4B (533fsb). The default voltage is 1.525 and i have mine on 1.625...and i get an overclock that is 2.7ghz. Full load i run about 57-58degrees. It's mostly prime 95 worthy. Is there a way i can get a better overclock, i've heard of these tings going over 3.0...is it possible?

I'm also using a zalman cnps 7000alcu heatsink and fan.
 
I have a 2.26GHz and two 2.53GHz P4's, all of them 533MHz fsb. At stock voltage the 2.26 hits 3.1GHz, and the 2.53 both hit 3.3Ghz, all on SiS661 chipsets.

I would drop the core voltage back to stock, and make sure and lower then memory divider, you should be able to get about 3.0GHz at least.
 
Yeah ~1.65v is really the threshold. You'll need extreme cooling if you push it much higher and you risk turning that Northwood in to an expensive keychain 😀

I'm running my pc3200 memory at 1:1, so it's actually underclocked but it has timings of 2-2-2-5.

If i lower my voltage then my overclock won;t be prime worthy, but i'll try it.

Why would 1.65 volts be max if it's 57 degreese at full load, that's not too hot is it?
 
No, it isn't too hot. But heat isn't the only issue. At a certain point you are risking frying the chip by inducing too much voltage through it. This is even more of an issue with newer chips on smaller processes as the tiny gates can handle it even less!
 
I had the 2.4b till a month ago.
I have Abit IS7 mobo, and had value ram in it along with a Zalman 7000Cu cooler. I got it up to 2.9Ghz stable, and had it running for months straight at times without a problem.
I didnt have to touch the VCore at all...which means if I did, i could probably go up to 3.2 or something. 1.625 isnt too high, But I would reduce it down to 1.575 or even 1.55 if I can.
Change the N/B strap setting to PSB667. And let the ram be default timings. See how far u can pump it up. If not, change the divider from 1:1 to 5:4 (although since u have ddr400, it shouldnt matter).
let us know
 
Yo OMG,, About the Keychain thing,,, Does anyone know how to drill through them processors without cracking the ceramic.. I've got a couple of Dead chips,, I've always wanted to make keychains out off, but i've never been able to drill holes in them..
 
Oh,, and some 1337 guy once said to me,, that heat isn't the biggest issue,, overvolting could damage the Micro circuitry hurting the gates .causing them to fuse together,,.. if any of them breaks,, u get Errors,, soon,, cold boot problems,,, then ,, simply error so much it won't boot...
 
My voltage was actually on 1.6500, but now it's on 1.575. My overclock (2.7ghz) won't run prime for more than a few seconds. But with the 1.65 volts it sould. Does it even need to be prime worthy?
Should i try to bring the voltage on down to stock? (but wouldn't that be worse?)
 
You should always try to keep the voltage as close to stock as you can. If you can get (hypothetically) 2.5 with stock volts or 2.7 but you have to crank the juice up 10%+ you are far better off with the 2.5 overclock.

Does my ovrclck need to be prime worthy? cause if not, then i could probablly jack the clock way up there. I use this to system to play games and occasinoaly do stuff like video editing.
 
Running prime for at least an hour means that you have a pretty stable system, it would suck to have it bomb out 2 hrs into reincoding a video or something...

I took my 2.4b to 3.33ghz at 1.65v but had high end air cooling...1.65v actual is only 10% above stock and should be fine...stay away from 1.7v and you should be fine....I ran my 1.6a@2.74ghz 1.71v actual for 1 year and then sold it and it still runs today but owner runs it at 2.66ghz (some even numbers)....

My 2.4c ran at 3.5ghz 292fsb at only 1.58v but i had to limit that one casue heat was already 58c clean to 66c after a few weeks....under 60c with decent case cooling should be fine...
 
hmmmm Lahire,, Don't push it,, would u rather have a computer that works decent, or one that doesn't work at all,, But Since prices are on the down,, u should prob consider an upgrade soon,, so if u break it at this point,, it shouldn't be a big deal,,

What is ur Powersupply and ur current cooling..
 
I have a Zalman CNPS7000AlCu CPU cooler, and i have 3 case fans, and my psu is a aspire 350watt (came with my case). I don;t wanna upgrade because i just upgraded alot of my componentsa few weeks ago, i'm kinda low on money.

Do i need beter thermal grease? i'm using the stuff that came with the cooler. Is the mad dog multimedia artic silver 5 the best? and if so should i get it?
 
DUDE,,,, U got lotta jiz in plugged in man,, OCing requires a very stable steady voltage, and the 9800 alone causes trouble for a 350 watt.. espicially the ones that come with cases, unless this was a 200 dollar case which i assume it's not because of the 350,, I would consider a new PSU ,, even a 500watt for like 50 bux would do the trick,, that is most likely ur issue.
