CPU Overclocking

Marky · 2 Mar 2008 at 12:47

Hey all,

I recently got an e8400 (3.0Ghz) and wanted to see how much I could overclock it (on air).

So I went into the bios and set the multiplier to 9 and the frequency to 350mhz (As opposed to the original 333mhz) to get me 3150Mhz.

Not much of a boost, but this is my first overclock

Then I went and put it up from 350mhz to 380mhz to get 3420Mhz.

When I got into Vista - I loaded up Coretemp and checked the temperature...

It was around 90 - 95C on both cores AND RISING :O

I rapidally restarted the PC and put the frequency back to 333mhz

My CPU is currently at 50C on both cores - is this an okay temperature... Just not sure why it went so high - is there something more to overclocking than just putting up the frequency?

Thanks,
Marky

Seems a bit excessive, especially since you have an after market cooler. Is the heat sink on correctly, did you apply the thermal paste correctly?

I used this thermal paste.
However, I have a feeling my CPU fan is broken as one pin just wouldn't sit down fully without one of the others popping out.
I'm considering replacing it shortly.

However, was I overclocking correctly? Is that all you do?

It wont be making sufficient contact, so that's why your temps are crazy.

As a rule I never let my CPU top 55 fully loaded.. Get that CPU cooling sorted!

If you have any suggestions - give us a shout - however I'm currently thinking im going to go with this.
I heard it's quiet, and very cool

You have the basic idea right, but also consider voltages and RAM dividers as per the OCing stickies. The highest my CPU goes is 55C fully loaded (e2180 @ 3Ghz) using the same cooler as you. On that cooler you don't need to worry about applying paste cos it's already on there, and it seems to be good stuff (MX-2?).

I was reusing the fan therefore I had to remove the paste

I'll take a look at the stickies
