Hi, and welcome to the forums!

Unfortunately, it is highly unlikely that you'll be able to overclock with your system, as the BIOS and jumper options on OEM systems are highly limited.

You might consider googling for a software-based overclocking utility, but that is a much riskier option. To use such a utility, you'd need to identify the motherboard maker and the type of clock generator setup on that board, which can be a bit of a trick.

Sorry to be the bearer of bad news ... but I'm sure that at the very least, we at the forums will help you maximize the performance you can get out of your current system.

Best of luck, and once again, welcome to the forums! :) -- Paul

There are only a couple of ways that you might get an overclock. If you can set the FSB via jumper on the Mb to 133fsb, and your Celery will run at 1600Mhz (12X133.3). A 33% O/C. Most OEM MB's support the standard FSB speeds so the OEM can use the MB across several models with faster/slower CPU's. Sort of depends on the MB and what Chipset it is, and what native functions it supported. They might also have used that MB with the P-III which used a 133 fsb so it may be available on the Mb. That kind of O/C usually requires some amount of Vcore increase I doubt you have that option on the MB.

You'll need to identify the manufacturer of the MB if possible, The Chipset it uses, and hopefully get a MB Schematic, showing all the jumper locations/Dip switches etc. and then see what options you might have. A lot of OEM MB's have the manufacturer's name silk screened somewhere on it, or a model number that is similar to one of the Manufacturer's retail products.

There is another possibilty although slim, I have an old Asus P2B-E MB which is an OEM version of the P2B-F retail board. It has only FSB options for 66Mhz and 100Mhz. There's no pins at the points on the MB where Other bus speeds could be selected. They are grounded by solder traces. Some judicious desoldering and soldering pins into the solder pads on the MB could give you other FSB options. The Chipset supports them prob. and the Clock generator. They're just not selectable because of the physical connection being dummied.
Just something to think about. How badly do you want to overclock that Celery? :-)

I highly doubt that his board has any jumpers for FSB selection. His only option would be to pull the BSEL pin to get it to default to a 133mhz bus, and if it wasn't stable he'd be stuck.

[macklin01]

Those were some good points. :)

I remember that older OEM boards often had jumpers, but I've yet to see that on newer OEM boards. Then again, it might well be possible.

Now, if you do manage to bump it up to 133 MHz FSB, make sure to use some very good cooling, as that's fairly high for the Celery 1200. The OEM power supply may also not be able to keep up. But it's certainly worth a shot. ;)

Good luck! -- Paul

well it has jumpers
i think that what it has
three pins with a little object on to of the pins right

what are you using your computer for?

what programs are slow for you?

how much RAM do you have?

if less than 256mb...then you should get at least 256 to 512mb

is this a celeron tualatin with 256k cache?

if so you might be able to overclock it on a different motherboard for $50...soyo TISU or Abit ST-6, etc...

i use coputer for gaming
it it tualition
512mb ram
one of my slowest programs running is c&c generals

if your board will support it, which i'm not sure it will, then you could try to run that 1.2ghz at 133mhz fsb....this would be 1.6ghz, which is not common with the tualatins (1.45-1.55ghz is much more likely with these chips)...and that will also likely require more voltage...in my experience anything over about 1.5ghz usually requires 1.6 or more volts...which you might be able to do with a socket-pin mod right on the motherboard...

of course you could also get another mobo that would allow overclocking and overvolting for that setup...$30-50 ebay-new

[gen. paradise]

could you maby tell me what motherboard to get

[dustybyrd]

could you maby tell me what motherboard to get


1st, you should make sure that the power supply in that compaq is a standard 20pin- ATX...

then i would get either the Abit ST-6 or the soyo TISU...the abit's cost more but are supposedly better than the TISU...although i have used several TISU's and i like them...

you should be able to get the TISU at www.mwave.com for $55...that's where i got mine...

i think someone in the classified section has an ST-6 for sale as well

i should also tell you that you have several other more expensive options...but also faster...

1) upgrade your video card (for 50-75 bucks you can get a 8500le that will be decent---i don't know what you already have and for 100 bucks you can get a Ti4200...that will be about 20% better than the 8500)...or if you have more dough then a 9500 or 9700 or 9800 for much more dough...THIS ALL DEPENDS ON THE GAMES YOU PLAY AND WHAT VIDEO CARD YOU ALREADY HAVE AS WELL

(2) upgrade to p4 or AMD...that will cost more but the performance difference will be about twice as much...

p4 2.4C $160
abit IC-7 mb $150
512mb DDR RAM $75-100

overclock to 3+ghz...

or AMD 1700+
NF7 mb $80-100?
512mb DDR RAM $75-100

overclock to 2.3+ghz

so it's about what you want/need and how much you are willing to spend..

Most of the good motherboards to overclock the Tualatin Celerons are very hard to find. You should be able to find a Soyo TISU board without too much trouble. It will run about $60 including shipping. It has vcore settings up to 1.80V. This is a fair overclocker, depending on the stepping of your CPU you should get 1600 to 1680. Once you see if your CPU will hit 133fsb, you'll have to remove the BSEL 1 pin or you will get a BIOS Checksum error and the BIOS will reset to defaults on each cold boot.

but, if he gets the TISU then he must first check if the cpu is stable at 133+ fsb....in my experience only 2 of the 6 tualatins that i have tested (all b stepping) could do 1.6+ghz....most did 1.55 though with 1.7 volts...

it's likely that his cpu is "A" stepping and might not do more than 1.5ghz anyway...then he doesn't have to worry about the reseting bios problem...

[gen. paradise]

thank you so much guys especially dustybyrd
as far as i am concerend is i am just gonna get the motherboard
everything else is set to go exept maby cooling
should i bother
i got a pci slot exaust fan 80mm aluminum intake fan xoxide.com has them
active memory cooling
so should i get a new processor fan or not

i have used intel's stock cooling and it is fine for up to 1.7volts and 1.62ghz...i am not using one on one of my machines now because i found a quieter one...

these chips aren't that hot with less than 1.7volts...but you do need a fan right over the heat sink though...

also, what video card are you using?

and do framerates matter for this game you play or only raw cpu power?


from your personal info it looks like you are using the radeon 7000...that is ok...an 8500 will be maybe 25-50% faster and then each jump in cost by $25-50 will get you maybe 25-50% more speed...(ie 4200, 9500, 9700...)

but again, this is important only if the game is graphics intensive...and framerates are important...

it could be that upgrading the video card would show a greater improvement in that game than the processor speed...maybe not though...depends on the game

[gen. paradise]

i have a radeon 7000 but that is not the problem with my gamwe it is the cpu it is to slow
when i play mohaa i cant run any other games when i play generals everything runs extreamly slow so it is the cpu

[Blunt]

or you could us a ASUS TUSL2-C i got one they are great
