Need some general help with overclocking my Q6600

post #1 of 10
Thread Starter 
Hey guys, i'm new to the forum and new to overclocking. I just got done building my new rig last night and was interested in overlcoking the CPU. Here is some basic specs of my new computer:

CPU - Intel Q6600
MOBO - nForce 680i
RAM - 2x 2GB Corsair DDR2-800 PC-6400
GFX - nVidia 8800GT
Also got a huge ass Asus heat sink you can see here: http://www.microcenter.com/single_pr...uct_id=0266464

Anyway I just need some general help on overclocking my CPU to avoid doing something stupid and frying the damn thing. I'll just be using the system BIOs to do it. I want to get a speed of around 3.0-3.2 to start.

Can someone show me the basics of overclocking this CPU for a newcomer. Also try to explian the technical jargin because I am very new to all of this.

Thank you guys!

I have that Heatsink....It's decent.

Which 680i Board exactly do you have (NF63, NF68, etc...). There is a really great overclock guide here...

Check it out and see what you can come up with...

Thank you so much for this tutorial. It helped ALOT.

I disabled my "limiting features" and started tweaking the FSB (just increased it by 10MHz to start) But I have a few questions.

I heard that increasing the FSB is the most commonly used way to overclock a CPU. But should i ever use the multiplier to increase the CPU? Should I sort of balance the use of the multiplier with the use of the FSB? Is there a good rule of thumb for this? Also should I every increase the voltage to my CPU? If so by how much per reboot? One last thing is there a sort of "don't go past this CPU temperature or it'll fry" sort of thing? Whats a good temperature for the CPU to be around? I understand that cooler is always better but is there a sort of golden area?

Thanks for your help

Theres going to be a point when you will hit a wall with simply increasing the FSB. When you hit that, then a combination of Vcore increases and maybe, maybe some adjusting of the multiplier (ie. Cant get 333 x 9 stable but can get 375 x 8).

As far as the voltage...the overclocking guides in previous posts have some MAX recomended vcores...but move up very slowly. A tiny increase is huge in terms of the CPU.

Lastly - temps. Every system is different, and depending on ambient...you will find a ton of variance in peoples opinion on this. I personally have 50c idle and 62c load...which some say is too high. The Tjunction max on mine is about 100... but I draw the line at about 68c-70c. You have to pick your "Safety Zone" and stay within that.

If you have all your "limiting" settings turned off the next step to getting your cpu to 3ghz should be just upping your FSB to 333x9. If your pc won't boot with that setting on stock volts then go back into bios and up the cpu vcore by just a notch or two.

You should be able to run at stock volts with 333x9, at least I was able to and it was rock solid. If you're set at staying at 3ghz then run Prime95 for 8 hours at least to make sure it's stable, 12 hours if you can manage to run it that long. If you want to go farther you're going to have to up the vcore more and more.

Alright I will give the 333x9 a try. Also Would it be better to use nTune to do this or just regular BIOS?

NEVER use nTune. Overclocking through Windows is almost guaranteed to mess up your system. Always overclock through the BIOS. If you have nTune installed, I'd uninstall it right now to be sure you never use it

For a Q6600, make sure to use CoreTemp to monitor your temperatures. Try to keep all cores below 70*C at load, and definitely under 75*C.

Ok good looking out but got a question about regualr BIOs. In nTune there a CPU slider that effects "reference clock(FSB)"(currently at 239MHz). When I use this slider it changes the CPU core frequency, FSB frequency, and the memory bus frequency. Where is there in the regular BIOs that I can change the "reference clock(FSB)" to the 333MHz? And do I have to change the CPU core frequency, FSB frequency, and the memory bus frequency seperatly or will changing the "reference clock(FSB)" to 333MHz sort of automaticly do that?
