Rapbii,

please post your system specs so people know what you have. Easier to help that way. Read these threads. They should have everything that you need:

Please actually go through the whole thread. You'll learn a lot, AND it should answer all of your questions. After that, if you need anymore help, post and let us know :smileyhappy: 

Rapbii,

 

I have helped numerous people with overclocking, if those two links above dont help you enough let me know where you get stuck.

Lol. Yeah, xps420OC is THE guy to go to (if you didn't notice, he's the one who helped out in both of the threads I gave you links to, with one of the threads being one that I had started)

THANKS A LOT xps420OC for all of your help!!! :smileyvery-happy: :smileywink:

 

ps. xps420OC, please read my newest thread, that I'm about to create (will be titled " XPS 630- Ruski07", lol) and please help me out if you can. Thanks in advance.

right this is what i did i linked the memory in bios to 1033 mhz they are 4 gig corsair dominator ram, bought seperatly from sweden. i have processor q6600 at 2.4 cang et it over clocked max at 2.7 ghz, still didnt get my anser replied, just want to know if i should unlik it and what nummbers for example fsb volts and all i would need from some one , and you say you overclocked it at 3.2 please help, would be thanking you a million times.

First of all, do one thing at a time - CPU, then the memory, then the GPU if needed or wanted.

 

Set memory mode to Unlinked, this was specified in threads linked to above.  Disable the "C1E" and Speedstep options in the BIOS CPU section.  In the BIOS Overclock section, for the CPU @ 3.2GHz I have the FSB set to 1400MHz I think, and set CPU voltage @ 1.35v.  If your system freezes, then the CPU voltage at 1.40v.  Try that and let us know how it works.

You need to manually try different voltage setting, depending on how much you OC (higher voltage for higher frequency). Here's a setting that may get your CPU to 3.2GHz:

FSB frequency = 1420

CPU voltage = 1.4V

FSB voltage = 1.35V

Chipset voltage = 1.4V 

 

If it's not stable, lower your FSB until it is.

  

Remember that not because your neighbor's system can get to 3GHz, you're supposed to get to 3GHz as well. None CPU behaves the same.

In the "VTT = 1.35V" you mention above, I'm assuming you mean the FSB voltage.  I don't remember seeing a VTT option in the 630's BIOS Voltage settings.

Yup, it's FSB voltage in BIOS. Sorry for the confusion. My answer was edited 

okey im at collage right now il try this when i get home i tried unlinking yesterday set the fsb to 1200 then different non works because the pc freezes or doesnt show screen, so i will look on what you have posted some great answers, i tried overclocking cpu yesterday i set volatage 1.4 and will look on these posts, i do not know why everything freezes when i raise fsb, if this works, this will be great!

i really need to thank you veru much your answer was so good followed all steps and pc is at 3.2 ghz, isnt that cool wohoooooooooo! thanx bud god bless you!
