Im thinking about overclocking my computer just a bit...

Heres my CPU:

Apparently it can be overclocked to 3.0ghz, but i dont want it that high. Just want to learn about overclocking really.


Can anyone explain to me what to do exactly?

You go to your bios. Do this by restarting computer and hitting delete button when it tells you to.

Then go to your CPU settings or wherever you see the FSB/CPU multipliers and all that.

Raise the FSB if im not mistaken, sry my core 2 quad overclocking is a bit rusty since i switched over to i7

It's as simple as raising FSB i believe from what i remember.

The difficult part is voltages, but it's not so hard once again on the core 2 quads. Just raise the Vcore a certain amount, nothing too dangerous. There are other voltage options to raise but i don't really remember them.

The final clock speed is calculated by multiplying your FSB with the CPU multiplier. Like in ur screenshot, its 332.6 x 6 = 1995 or basically 2ghz.

Also, turn off intel speedstep, i can tell you have it on during ur screenshot because ur CPU is downclocked.

Also, make sure u have adequate cooling. Making an increase to 3.0ghz will be pretty simple if ur temps are safe and it will be a pretty large increase over stock.

What do you mean my CPU is downclocked? :o


And ive heard about prime95, what exactly does that do?

Downclocked means ur cpu is running slower than it is supposed to. I believe a Q8300 runs stock @ 2.5ghz

Intel speedstep which is a power-saving option, downclocks your Q8300 to 2.0ghz when your idling. For overclocking, we usually disable this option. In other words, it would keep your CPU running at 2.5ghz 24/7 if you disable that feature. Instead of 2.0ghz when ur idle and 2.5ghz when ur gaming.

Prime95 is a stability program, it tests your overclocks and see's if it's stable or not. It is the preferred program to use.

Prime95 uses your computer to try and calculate a new mersenne prime (a number that can be expressed as 2^n - 1). Beside that, it has a stress test function that can be used to test your systems stability. Because calculating a prime takes a lot of work, it stresses your CPU and because there are so many digits (trust me, A LOT) it uses plenty of RAM.

Depends, there are different types of tests on it. Blend tests does like everything and stresses the RAM a lot more. The smaller FFTs work the CPU mainly but don't involve much RAM.

Yeah, yeah. Long story short, if you fail one of the tests, something is wrong.
 
yup......he shouldn't be worried much with the ram as he isn't overclocking it when he overclocks the CPU like the i7 does.

Actually, it works the same as an i7 and the memory frequency increases dependent on FSB frequency, if the RAM and FSB are set to link and/or sync(link & sink means the DRAM speed is automatically equal to the FSB speed). Most overclockers recommend linking and syncing.

Ex. 400Mhz FSB set to link & sync means RAM would be running at 800Mhz(DDR stands for Double Data Rate, so 400x2 = 800).
 
So since I'm downclocked at 1.9ghz right now, how do I clock it up to 2.5?

Is it to do with the power setting?

And where in the bios do I go?

Ahh yes.......my bad, i kinda forgot about the way it worked. Havn't overclocked a quad in a while ever since i got it, but now its sold and gone.

You don't need to get your clock up to 2.5ghz.......it is at 2.5ghz but it just doesn't run at that speed when your idling. Only when your playing a game or something does it actually run at 2.5ghz.

Just disable intel speedstep in your bios when you overclock.
 
Well first things first, what kind of cooler do you have on your processor? If its the stock intel one, i wouldnt personally try overclocking only because the stock cpu cooler is junk. If you upgrade that cooler, you can push that cpu up to 3ghz i think. It may sound like a big jump but for an intel cpu .5ghz increase over stock speeds isnt hard to obtain. I did almost a full 1ghz overclock with my old cpu went from 2.66 to 3.6 and it was stable.

Next, you'll want to enter your bios. Do this by hitting delete or another key, you pc will tell you when its booting.

If you have a dell,hp, gateway, etc... you will most likely not be able to access the feature to overclock.

to overclock you need to go and select the FSB or Front side bus. I would reccomend increasing by 5-10mhz at a time and boot until the computer will not boot or you obtain your desired overclock.

Use core temp to check your temps and run prime95 to run a test for stability. Id say run it for 4+ hours if possible run it overnight to ensure your pc is stable.

If its stable then your good to go if its not you have 2 choices.

Choice 1. Decrease the mhz by 10 or 15 and try another prime95 run.
Choice 2. Incease the voltage going to your cpu by a little(about .025volts). and try a run.

Good luck and dont increase the voltage much. I personally just go for the best overclock i can get without touching the voltage.

and more questions just ask in the thread or feel free to pm me.
 
Thanks! But how do I turn off speedstep? I'm not familiar with it
 
Oh, and i chcked it out, when my pc idles it runs at 1.9GHZ to conserve power, but once it un-idles it goes at 2.5GHZ again

lol thats exactly what i said hahahaha

It's kinda hard to explain bios. Just get into it and explore, honestly, its not hard to learn if you just explore it. You don't need to change any settings but just go through each one and see/gain knowledge and experience.

Alright, thanks a ton man

Mmm. Really don't just start fiddling around with things. Overclocking is easy once you get it down. Find what your motherboard is and look at a overclocking guide for its bios, every mobo has different bios.

You really shouldn't be trying until you tell us or load temps, you can easily fry it if it already runs hot, upping voltages and oc'ing our CPU really increases the temps.
 
Yeah, fiddle around with everything except voltages until you learn more about them...lol.
 
Im gonna put together a pc using cheap and used parts to learn overclocking.

Messing up a pc you share with 3 others isnt a smart idea.
 
If your lucky your processor will be a nice OC'er and you can keep your Vcore on your default. CPUS all have different VIDs (default vcore).

I love the q6600 for the fact that I kept my default voltage yet went from 2.4ghz to 3ghz, with stock cooler even. (g0 stepping ftw) Since I didn't have to change the voltages I pretty much kept the same temps.

I wouldn't recommend ocing on a stock cooler for many other cpus other than the known good overclockers, 920 etc.
