Eagle's Oc log (tips appreciated)

post #1 of 30
Thread Starter 
Alright I have tried some basic ocing but I want to go a lot furthet this time. See how far I can go and keep my system stable. I know that the real bottle neck is my memory. Its 1gb of dane-elec (2x512) and 512mb of Kingston (2x256). The dane-elec isn't the best memory for oc and kingston isn't a lot better.

Here are the stock specs:
P4 2,8 GHz northwood
FSB : 200Mhz
MP: 14x (can't change it)
Temperatures (Celcius): idle 39/40, load 50/55
Vcore: 1,5V

Alrighte here we go. I will update on a regulair basis. I had to work these past few days so I didin;t have muc spare tie so did small stemps and just activated the stress test. So when I came home from work it had been running for 10 Hours.

Step 1:
Increasing the fsb to 215 (Earlyer attemps where at 220 but I want it stable this time). Cpu speed is at 3,01Ghz. System ran stable for 10 hours (a combination of prime95 torture and cpuburn at the same time). Temperatures are still the same. Sometimes a peek at 56 Degrees, but that for less then a second.

Step 2:
fsb to 221. Cpu at almost at 3,1 Ghz. Ran stable for 10 hours again. Temperatures still the same.

Since the temperatures didin't change I increased my vcore to 1,6v. To see how it affected the temperature. 100% load temps shift between 55/58. (the temperaure peeks for a second at 58 and then goed back to 55 and stays on it for e few seconds, so the temperetaure is still 55Degrees but it sometimes peek up for a second. I kept the vcore at 1,6v. I can always lower it when I like the results and see if the system keeps stable.

Step 3:
fsb to 229. Cpu at 3,2Ghz. Came home from work and when I walked in my room I was quite supriced to hear no noise. Wich is weird cuz the high temperatures kick's my zalman cooler to the max rpm. Turned on my monitor and was amazed at the stable test time, 8 minutes

Step 4:
fsb still at 229 but I have changed the cpu:ram ratio to 5:4. The memory is at 183MHz now and a short 30min stress test was stable. I will try a longer one later on or tomorrow.

My current goal whould be an fsb of 250. At this fsb and the cpu:ram ratio my memory will be back at 200MHz. And if its still stable lest see how close I can get to the maximum of my motherboard wich is 300fsb. (at least thats the maximum I can set in the bios).

Alright ill keep you guys updated. Feel free to comment or post some tips.

Yeah its cold outside, but I want it to be stable in my room and get it as high as possible

What the point of oc to the max f you can only use it for 8min at a time..

I did another torture test and it ran for 1 hour and is still stable. I will probably try a longer one tomorrow to see what happens and then knick it up a little bit more.

Yeah but still having a duck like that hanging around...

ill start a stress test in a few minutes and let it run for 4 hours, when that is stable ill knovk it up a bit. I know that I can go to 230 from the past but my memory wasn't divided so I got errors, lets see what happens now

I've been tempering around a bit. i don't remember al the steps but i'm currently at:

CPU: 3,33 Ghz
FSB: 238 Mhz
CPU:RAM: 5:4
Vcore: Wel its odd. I've set it at 1,7v but cpuz is displaying. 1,616 to 1,648, as im typing it started shifting between 1,600 and 1,616.

Seems like prime95 is running stable, only been 30min now. But when I go to 239MHz it won't even run for a few minutes.

Should I increase the vcore a bit, lets say another 0,05 higer or is that to high? Afther an updated bios my temp are displaying right (was a bug in the bios software). I'm at 53 degrees full load 100% with al my fans maxed out).

The max temp for Northwood processors are 55 degrees... so dont go over that!!
I wouldn't recommend you going higher... Cause you can cause damage to your processor...

You got a good overclock there! But if you buy a better cooler, you should be able to get even higher..
I got a Intel P4 Northwood 2.6GHz myself, and I've overclocked it to 3.3GHz stable.
