Hi guys. I have zero idea about overclocking. I have always tought of overclocking has to do with us adding stuff and soldering it to cpu. am I right ? or you just do it by changing the setting in bios or with some softwares ?. If anyone can give me a link to like overclock 101, with simple instructions (easy words), I will greatly appreciate it. thanks
 
overclocking now a days is just changing settings in your bios.
search on google for overclocking guides.
 
Most of it has to do with typing settings in the bios

First thing needed is the right hardware. A motherboard that allows overclocking and RAM to go with it. Then, it's all about being lucky and getting a CPU that can overclock. However, the new Intel C2D cpu's will overclock regardless. It's so simple that even my father does it now.

not usually, it was different by to overclock you had to change certain jumpers or switches to make the cpu run faster, instead of doing it in the bios.
 
lol alright, thank yo guys. I will google for further and deeper infos about this :)

it could, sometimes you had to jump circuits ti boost power, and then solder resistors on the more sensitive circuits to prevent damage... it was a bitch.
 
my brain been overclocked hehe

I just spent 4 hours reading many articles from diffrent site about overclocking
So basically, I pretty much have alot better understanding of it now. Only one that I don't really get it, is the CPU:RAM ratio.
here is what I have learned so far about the ratio and please tell me if I'm wrong or not:
Lets say I have ram that has max 400mhz speed. Then I want to raise the current FSB speed to exactly 400mhz, so I should just leave the 1:1 ratio alone.
However if I push the FSB speed up to 450mhz, I should set the ratio to 9:8, so that my ram will still be runing at it's max speed of 400mhz. am I right ? thanks
 
You are right, however if your using a newer hardware you won't be able to go under 1:1. If you using a skt 939 board you will, but I have the feeling your using a C2D if you want 400 fsb.

Your ram will be able to OC some to a lot depending on what kind it is and all.
 
Well, some boards will not allow you to run the RAM below the speed of the FSB.

You'll RAM will be happy as long as it matches the FSB.

That's the reason for knowing what components to choose from the beginning.

Right now, Intel's CPU's run with a FSB of 266mhz. The RAM that is required for such system is DDR2-533mhz (DDR2 / 2 = 266hz).

Getting DDR2 800mhz or 1000mhz is the smart thing to do since it will allow you to run the FSB @ 400mhz or more.

Also, you don't have to overclock the FSB to run the ram @ its 800mhz or 1000mhz speed. You can just use a 2:3 or 4:5 ratio to allow the FSB to run @ 266mhz and the RAM higher.

RAM can also be overclocked. When using quality ram rated @ 800mhz or so, if it is any good, it will most likely run higher than stock speeds, like 900mhz or even 1000mhz.

Then you have RAM timings. It's not such a big deal, but a lot of users want to squeeze 1 or 2 extra seconds here and there by playing with RAM timings, which can be a pain in the a**. Don't worry about timings, other than the stock timings!

The new Intel chipsets and Core 2 Duo cpu's make overclocking very simple.

Any C2D
An overclocking friendly motherboard
Fast RAM
Good CPU Cooler

And game on!

I made good cash back in the day... I worked for a guy repairing motherboads, token ring, ethernet and memory expansion cards for IBM PS2 and Value Points....

I was able to overclock cpus back then.. made mad side cash at it... gave my boss money for crystals and installed them at work on my lunch break....

funny how you take a 8mhz crystal out and put a 16mhz crystal in and double your speed....

HAH 16mhz!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
fer all ya youngins..... yeah that is not giga but mega!!!!!!
here with core 2...
e6420 vs e6600 is a mere 2.1 vs 2.4GHZ... 300mhz diff!!!!!!!!!!!!!! :D

lol you guessed it right. actually I was just making up the 400 FSB for the case example above, as I had no idea if C2D has 400FSB, until you said it.

since I have problem with english, the best I can say about what you are saying is that you are talking about overclocking the ram only instead of the cpu ? or if I raise the cpu FSB, lets say from 100mhz to 130mhz, and if there is still some extra mhz capacity on the ram, lets say the ram stock speed is 150mhz, you squize out that 20mhz extra by setting the ram number higher in the FSB:RAM ratio ? mann so many question marks :D I'm sorry guys
================================================================
================================================================

anyway The cpu and mobo I'm getting are this
E6400 and
DFI Infinity 975X/G. I'm getting both used from a guy on this forum (maybe that's not really important lol) and the RAM I'm planning to get is this Crucial Ballistix 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)

I wonder if that RAM will work fine with the other two components. anyway, just to make sure that I understand, DDR2-800 (PC2 6400) does that mean it's factory speed is 400mhz ? (from 800/2)

I see on the detail that E6400 has its FSB = 1066MHz, and the mobo has its FSB =1066/800MHz, where the memory standard it supports is DDR2 667.

I am getting really lost (I tought I knew this subject already :D). I see the e6400 runs at 1066mhz while the ram is only 400 mhz, I think there's no way the ram is gonna match that 1066mhz, the ram will just burn up. the same thing with the mobo and ram, the mobo has got twice speed than the ram. I need some voltage for my brain, help me clear on this problem please :D

1066 MHz is the rated FSB, which is quad-pumped. To get your true FSB, you take 1066 / 4 = 266.5, so basically 266 MHz. Since DDR = Double Data Rate, you multiply true FSB to get RAM speed. 266 * 2 = 532, which means DDR2-533 (lots of odd rounding done). Since you want to OC your processor by boosting your FSB higher than the rated 266, it would be easier to have higher speed RAM (right now, DDR2 is cheap). This way, you're OCing your processor only, and not OCing your RAM.

That DDR2-800 you're buying won't be stressed at all until you hit a true FSB of 400, and then you still have a little room by OCing the RAM as well. Using the stock 8x multiplier, that puts your E6400 at 3200 MHz.
 
Just for the historical record, back in the days of dinosaurs and original IBM 4.77MHz PC (1983ish) and even prior to that with Altair computers it was common to unsolder the crystal that was used by the clock generator and solder in one with a little higher frequency, probally the first OCs ever done were by that method as there was no bios settings or even jumpers/switches for changing the speed, every thing was designed to run stock and that was it.

Thank you so much. very well and plain explanation :). I really learn alot of new things from u guys.
Now I know why E6400 is 2.13GHz ( from 8 x 266) :D
more questions :p :
why or what Intel rate its FSB at 1066 for ?. I mean, they should just state in the spec its true 266Mhz. newcomer like me really gets confused on that

and the final question (hopefully :eek:) I can only push the e6400 FSB most up to the RAM speed( in my case 400mhz). and If I decide to get the DDR2 1000, I can set the e6400 from 266mhz to 500mhz max. in the history of overclocking, is that safe to do ? has anyone ever accomplished that ? I mean what's the safe enough FSB to raise in general, especially for a newcomer like me, who wants the cpu run faster a little bit but prefer safety first, and also there won't be any fancy cooling parts in the case. Thanks

that's craazy lol. I'm just glad we have alot of brilliant engineers outthere who make our life easier :D
 
Just like the guy above said:

The ram you will be getting works @ 800mhz DDR2 or 400mhz. (This is actually very good RAM and you could easily overclock it to 900mhz or more)

The 1066 FSB of the motherboard is a "QUAD" figure. Divide that by 4 and it is only 266mhz.

The RAM needed is 533mhz DDR2 (or 266mhz). You are getting good RAM which will allow you to push your FSB to @ least 400mhz

400 FSB with 800mhz DDR2 (400mhz) on the RAM. That should give you a nice 3.2ghz overclock

In the bios, you will need to adjust the CPU voltage from AUTO OR DEFAULT to 1.4V or so for the 3.2ghz goal.

You'll also need to manually set the RAM voltage (2.2V) and timings (4-4-4-12)
 
alright orion, thanks :)

now another question pop up in mind. if I use 2 stick of 1 GB of that DDR2 800 ram. would that mean I have a total of 1600 (800 true), then I can raise the FSB from 266 up to 800 ? or it doesn't matter :eek:
 
no i doesnt double up like that, only the amount of ram you have changes when you add more ram, i sih the speed increased like that :D or the short version, it doesnt matter, it will still be ddr2 800 and youll only be able to 400fsb.
