Overclocking my p3. I'm gonna do it! If I can..

bugler

Right.This has dragged out a bit. My manual says only 100mhz RAM is supported, so does this mean it is the same for the FSB? I tried d/ling softFSB from that site u gave a while back Gerry,but its been taken down for unspecified reasons(softfsb, not the site).There are no options in BIOS for me.Give it to me in plain english What must be done?

if you need softfsb still, here it is

oh very good thread...i want to do the same...listening intently for gerry's response please

also...just a quickie, not a thread stealer. is it better to reload an OS like MIllenium or 2000 after you change cpu's/upgrade? ie i had a celeron 500 working under millenium and now i have a p3 866 under the same HD/no changes/same OS....is this stable or should i reload the OS (please no debate as to whether millenium is better or not)

Some P3's are clock locked.

If you have an Intel mobo (like Dell & gateway ship) you have to flip a jumper on the mobo to enable Diagnostic mode (or something) - this will enable you to adjust the bus speed in the BIOS. However, as far as I remember, it will not boot in this mode, so to boot, flip the jumper back to normal. Asus and Abit boards can do it from the normal BIOS and boot operation; I think it's just a "consumer" safety feature Intel do with their own mobos.

Yankinlk: there is no need to reinstall your OS after you upgrade or overclock. It makes damn all difference to the software; the errors lie in the hardware you have not being able to take a higher than specified bus speed.

HDs generally are OK; modems can be pretty much on and off depending on quality. Any error Windows or whatever throws up is a hardware fault and basically making things unstable, you can eliminate the error by simply undoing whatever was the most recent change you made.

No need to reinstall Windows, again. And like I said, the errors you may get (from the video being utterly ballsed up) are all due to the cards and hardware you have. This is where it pays to have good quality stuff, not bargain basement type stuff.

I don't know if USB is also affected; I presume it is. NO harm in trying I suppose, but make sure you don't get too ambitious to start with. Start in small jumps of maybe 5 MHz to start with. If it's all good, go for more, etc., . Even more dandy is fiddling the voltage of the CPU, but you're in dangerous ground there if you don't know what you're doing.

you really are a techi aint ya red moose

nice 2 have u handy

Gerry

if its a dell or gateway bx chipset board, even diagnostic mode more than likely won't let you set a 133mhz bus speed, unless they had some decent boards in their later revisions. If you can find out what motherboard it is, that would be very helpful. The fsb adjustments, if any will more than likely be through jumpers on the board. Softfsb will work only if your motherboard's clock generator is supported. Main thing is to find out what motherboard you have.

DiscoStu

your right about the gateway 440bx based mobos. the diagnostic mode wont allow you to alter the fsb. i know because im stuck with one of those 4 year old piles of turd in my puter. oh well

I have a P3 500 on an Intel mobo from Gateway, about 1.5 years old. Maybe I should have a go and see if it's changed. I never overclocked it because I had no need of a few extra MHz (didn't seem like much and I could get my hands on one of thos old Celerons that could clock up to around 700MHz from 450 or so - Intel withdrew them pretty sharpish).

yankinlk

i swear im not stealing this thread....

p3 866 (not overclocked yet)
msi 6309 motherboard (very overclockable it seems)
256 pc133
soon to be geforce2 gts
100mb network card
onboard sound
scsi card and SCSI HD
OS is millenium, but might put 2000 on.
nice 300watt case, lots of fans

System chip set = Intel 440BX AGPset

Shíte.Bad news I take it

If that can't be o/c, would ye recommend finding a slot 1 800mhz or 1 gig or else getting a new MOBO and an Athlon? This 600 isn't going to last forever.....

Motherboard is an Intel SE440BX-2

Gerry

By the looks of it, you will not be able to run the board at 133mhz. So you can either get a p3 850 for it, which is officially suppported by that board, or get a new board, case, cpu and memory.

Gerry

yes, we know its a 440bx chipset. Thats not what determines whether your machine can be overclocked or not. So can you find out the make and model of the motherboard, or even the make and model of the machine?

bugler

Its a Dell Dimension XPS T600r, as for the MOBO itself,the only reference I can find is posted above.I'll open it up and have a look at it, but I'm not really sure what I'm supposed to take down or be looking at...

This of any interest?

There are actually revisions of the BX? oh cool. I better find out which one I have so. i'm planning on getting 256 or 512MB of PC133 ram and I'd like to overclock it if ossible.
If i was to put the FSB to 133 and reduce te clock multiplier would the CpU be more stable? I only have the standard fan on ti atm
