Ok I have the Intel Core 2 Duo E6750 Conroe 2.66GHz processor. I hear people can overclock this to at least 3.0Ghz without changing the voltage. I have a stock cooler on it but Arctic Silver thermal on it.

CPU-Z


My Idle temp with stock cooler is 29c-31c

Try setting the multipler to 9, if that works monitor the temps, should
be ok though. If that doesnt work, try bumping up the fsb, a little at
a time until you get the desired speed. The key to that is little adjustments.

Warfare

After that should I run prime95? If so is there a tutorial for running the test with that?

Warfare

Hmm, my BIOS seems to not want me to overclock. It will not let me set multiplier to x9.

Here are some pics of my BIOS

My CPU config



It telling me x8 is max

What motherboard do you have and whats the BIOS version? Might want to throw that in there.

Warfare

My Motherboard is in my system.....

P5N-E SLI ASUS

I forget what My bios version is. Cant I check that in windows somewhere?

Kinda lengthy but it explains it well.

BIOS revision 0901 , 2/1/2008

You should definitely update your BIOS. See if that resolves the issue, seems they had a lot fixes.

Warfare

how do you update bios without being in windows? I remember someone saying never flash bios in windows.

FALLOUTGOD

"The E6750 has a 6 - 8 multiplier, meaning that your motherboard will need to handle a 500FSB to hit 4.0GHz... a tough task."

There should be instructions on the ASUS site there as well as you board specs. At this point all things considered you should still update the bios but you will have to go by FSB speed to increase performance.

What should I put my FSB to if I only want it to get to 3.0?

Warfare

I also can not find where my FSB is located in my BIO's could you help me with this?

Don't worry about your multiplier, leave it on the maximum of 8.
What you want to do is raise your bus speed, and you're in the wrong place for that.
Close but no cigar. The Advanced is correct, but you need to go into "jumper free settings."

AI Tuning ........................... Manual

System Clocks ....................NB PCI-E Frequency....... 100

Voltage Control ...................Manual (for now)

FSB and Memory Config ........
FSB - Memory Clock Mode......... auto
FSB - Memory Ratio ................. 1:1
FSB (QDR) .............................1400

Note that your ram will be then be running at 700Mhz. This will change as you up the
fsb, and the 1:1 ratio will need to be tweaked (possibly) later on, if you exceed 1600
on the fsb. You most likely won't be doing that on a stock cooler. Always keep an eye
on your actual memory speed, with 800Mhz ram you don't want it to go too high.
We'll need to look at ram voltage at some point, when overclocking it's usually best
to manually specify the manufacturer's maximum, for stability.

Save and exit, boot into windows. Open up things like cpu-z and whatever temp monitor that
you use. Run prime95, paying careful attention to your temps. I don't like going over
60C. though a degree or two isn't a problem, but if it's the case, you really do need a
good heatsink. You aren't destined for much with the stock.

Warfare

when I tried that it brought me to a black screen saying unable to boot. Ill try it again today.
I know that I cant get far with stock but I can not afford a new one right now, I just bought a new video card.


Any recommendations for a CPU cooler?

I need some help with this some of this doesn't look right.









This one is similar with the rest in this category

Change voltage control to auto. For now with a small OC, it's best to let it set itself where it needs.

Try fsb - memory clock mode........... unlinked
Then see if you can set the next one down - fsb-memory ratio..... 1:1
And then up the fsb (qdr) to 1400.

After you enter that, see what it gives for actual mem.

Kind of a sparse bios, much easier with the AMI bios that Asus uses.

The thing to look for is the actual values.
Your cpu speed is the bus speed x multiplier. With the bios displaying fsb instead of
just the bus, you divide the fsb by 4, then multiply by 8. 1400 is 350 on the bus, times
8 gives a cpu frequency of 2800Mhz. The bus speed increase isn't much, 333 to 350 on the first jump isn't big, so that shouldn't be any problem at all with the stability.
Has to be in the settings.

This is my Overclock so far... About to run PCMark, 3dmark06 and Orthos for 8 hours. I am wondering if I should stop here because I reached my goal, I only have stock cooling as of now.

I'd like to know what you guys think!

PS when orthos ran for the 1 minute the core temps would only get to 58c and stay there or go down. I think you said that try not to hit 60c.

manic

That looks real good! I wouldnt push it much farther. Keep a eye on
the temps....

Warfare

temps getting at a max of 60c with orthos.. Once it hits 60 it goes to 59c.. Might have to put this down a little..

I put it down another 25 and it seems to stay at 59 under 100% load.. It makes a few jumps up to 60..

grimx133

Well done with stock cooling. You'll be able to get more, and keep the heat down, with an aftermarket cooler.
