Im a total n00b at overclocking. I realllllllly wana OC my system, but have aboslutely no clue on how to do it. If anyone would care to post on how to overclock (very basic) it would be greatly appreciated. Specs on my PC are:

Intel P3 Celeron 1000 mhz
640 mbs of PC133 RAM
30 gig Western Digital HDD
Stock fan on the CPU
A back case fan
Stock PSU (not sure on the power it actualy has)
Not sure on the mobo

If anyone could post here on how to OC it would be greatly appreciated....Also anyone have any clue on how to turn off a 3.5 inch floppy drive light? It is hooked up correctly, and the little light wont go off, the drive still works, the light just doesnt go off :-\

go to BIOS and change the FSB. The light makes your case pimpin. just leave it on it it 1337.

When you first turn on your system, during the post screen, there will be a message similar to "Press del to enter bios". Do that and once in bios look around for FSB options. To overclock you simply change the FSB to a higher value.

IF your celeron is a Tualatin then the stock FSB is 100 mhz. Depending on your bios you may be able to adjust the FSB in 1MHz increments. Start slow and reboot after each change. After you reboot run a CPU intensive app like 3d Mark 2001 or sisoft Sandra burn in wizard to check for stability. If it is stable go back to your bios and bump it further.

On a side note, I have built 14 systems with 1.0Ghz celerons and ALL of them would do at least 1.33 (133MHz FSB speed). My current system uses one of these celerons and is at 1.66(166 Mhz FSB). Mine is watercooled though.

If I were you I would start by going to 110FSB, if that works then go to 115, then 120, 125 and 133. Most of the ones I have dealt with would do 140 and a couple would do 1.5....all with the stock Intel heatsink.

There is another adjustment in the bios called Vcore, it changes the voltage that is sent to your CPU. Sometimes bumping this value up will get you higher overclock speeds, but it also increases temperature and *can* fry your cpu, so be careful. Your stock Vcore should be 1.5 volts, I would not recomend anything over 1.6.

At 1.6 volts my system would not shut down normaly, i had to use the power button to do it, thankfully I can run 1.66 with the Vcore at 1.55 so everything is good.

EDITED because I kan't spel

Thanks for the info.... I went and tried it out. I tried at 5 mhz increments. After I got to 125 it started to go down in mhz. At 130 mhz FSB speed, the CPU reported in as a 970 mhz.... you have any idea on why/how this could have happened?

You are very welcome.

Without knowing your motherboard model it is VERY hard to say why that happened. If you could find out what kind of mobo you have it would be very helpfull.

Also, try 133 FSB, that is a "supported" FSB speed meaning your PCI and AGP bus will default back to normal speeds. It *may* have something to do with that.

You can check out this link from our forums, and read others in the OC section.

This was about AMD overclocking, but the principles are all the same.

Some notes about Intel overclocking:

All newer Intel chips are Multiplier Locked, including yours, so understand what the multiplier is about, but also accept that you won't be able to change it.

Newer Intel manufactured motherboards do not have any FSB adjustment options in the BIOS, so if it is a True Intel board, your just out of luck.

And I wish you good luck, call if you need more help

Hello, I know your a long time poster here but you really should read all the posts before posting

He already stated that he changed the FSB some


Even though I am a n00b here I really do know my stuff.


Also, what you are saying about Intel mobos doesn't exactly apply here, he stated he is running a p3 based celeron which pretty much rules out "newer" Intel mobos.


The Intel 815 chipset is pretty much the newest viable option for socket 370 and it does support overclocking, even if it IS limited. Proof can be seen here .



EDIT: I re-read your post and noticed that you said "true" Intel motherboard. I agree that the options for these mobos are limited but you can still set a 100Mhz FSB chip to 133. Also, if you will notice he sated he was able to increase the FSB by 5 MHz increments....that means its not Intel.

Well I spent some time researching what kind of mobo I have (pulled out the mighty mobo book =) ). It is a Shuttle Spacewalker AV18E. I also went back and tried some more FSB settings, it seems that anything over 121-125 mhz freezes the PC during loading (at 123-125 I get a .dll error file) but anything higher than 129 mhz just makes the CPU clock speed lower. The stability of where I am at right now 1.2 ghz seems fine, I ran both Sisoft Sandra and 3dmark 2001 just fine.........

Oh yeah the new look of the site is pimp....nicely done =)

Hey RamRod, it's awsome that we have so many guys here that enjoy helping out.

Don't worry about my toes, if you actually step on them, one of the other Regs will probably yell before I do

Since what you had said before was all true, I didn't try and clarify any of it. I did offer additional information that would hopefully help him either now, or in the future.

Many peeps come and ask for specific information because they have specific problems, but I like to actually teach, which I feel goes a step beyond inform.

My sig says it all

Wow lc.

You earn more and more respect from me every day!

You are one of the most knowledgeable guys here, but more importantly, the most level headed and the most willing to help!

OK, enough A$$ kissing. Just wanted to point out that your contribution here is noticed.

I was going to jump in and post.......and am currently still chewing my tonque.

Something I should probably do more of!

Anyone have any clue why I can't seem to be able to go over 130 FSB without the CPU clocking in lower than if I set it at like 120 mhz?

I know exactly why, your computer won't let you. Next.

Thanx Putwig.

It's just that it's way too easy to take offense in a forum like this and the fights just get stupid and waist everyones time reading them.

They get perverse like a Jerry Springer show

As for your problem Third_eye, I'll look into it if Putwig or RamRod don't beat me too it.

BTW, there are three versions of your Mobo;
V1.3
V3.x
V4.x
Actually, the x means there are even more versions, but the manual is the same for each major version listed.

EDIT:

Ok, in the Frequency/Voltage Control section there is an option called "Auto Detect PCI/DIM Clk" What is this set at?

Also, you have two sets of jumpers, JP4 and JP7, what are they set at?
(You may find info on them in section 3-2 of your manual if it is the same as the V1.3 I am reading from.

Holy Hell, I have the SAME EXACT mobo, you must just have an unlucky CPU....all I can tell you is push it to whatever you can and be happy with it.


What I can't figure out is why it reports a lower speed at certain FSB speedws, mine is completly perfect up to 166 which is the max for this mobo.

To get 133 you have to go into your case and change jumpers, if you found the mobo info then you can find the jumpers Keep trying bro, you'll get it

Point taken Ic. It is apparent we both know what we are talking about and therfore compliment each other quit well.


This can only be seen as a good thing for n00bs to computers.

Allow me to rephrase. I have the AV18e 3.1 so we may not have the "exact" same mobo like I stated earlier........I am looking into your problem now.

Hey RamRod, read my last above, it has edited info.

So if I want to go over 133 mhz i need to go and change the jumper on my mobo? I have the section open and am reading about it now in the manual, but it says remove all jumpers to set the FSB to 133 mhz....does that mean it puts it at exactly 133 mhz, or does it mean I can go higgher than that. there are 4 settings it can be set to, jumpers on the 1st 2 rows= 66 mhz, jumper on 1st row only= 100 mhz fsb, no jumpers= 133 mhz FSB. but it also states that if I want to set the FSB manually to put the jumper on row 4. i havent messed with any of the jumpers so my guess is that it is still on the 100 mhz setting. I ran CPUcool and my CPU temp is only 33 degrees celcius (91 degrees farenheit)

ok ill check the voltage thing brb

Hey guy, don't forget about that BIOS setting I asked about, it could be what's holding you up. Is it enabled or disabled?
