I believe you hit DEL when Windows starts, this gives you set up. And then you use arrow and +'s -'s to change clock rate, then F7 (?)to save changes.
You don't want to overdo it because it can damage the CPU, gets overheated.

Pongi
I love advise that makes no sense. Some
motherboards can be overclocked and some cannot. All overclocking is done phsically
on the motherboard with your jumper settings
First you can increase the bus speed and then you increase the cpu clocking and usually in this order. Intel pentiums and most AMDs will
take an overclocking but overclocking a cyrix
is not recommended. If you need specfic information on your Board and CPU try
www.tomshardware.com This site is excellent
on overclocking and the ratings of equipment.

Good Luck, John

jmeara, some bios (very few) will allow you to change the CPU clock rate, which is what Forest was trying to explain.

Hey End
You dont have to stick up for forest. It
is apparent that if you have very little knowledge in system administration you should
not try and help out other people. All of the
knowledge is out there but sometimes you just need to study it so you really know whats going on before you try to help other people.
Im really not trying to bash anyone but if
forest would go to that site and read it he will know alot more about it next time. And by upsetting him a little maybe he will visit that site. Forest I am sorry if you were
upset.
John

You know what?
Im outta here and Im deleting this site from my bookmarks. Most of you are a bunch of
sniviling little college kids. All that I can
say is good luck to every one especially to the people that take some of the advice on this page. Its amazing to me how much flexing is done on this site and not enough learning.
To all of the people that really have machine problems I am sorry and the best advice I can give is once you follow some of these directions and really screw up your machines I just hope it is in my area so you
will be forced to bring your machine to my shop. Just make sure that you bring your parents credit card with you.

Cool, a flame war. All Forest did was forget to say his solution works for him, but might not for Pongi. I'm not a sniviling college kid and any advice I give is only to try and help. I think it's the same with the advice from all the others. People are here because the mfg's won't help after dumping their crap on us. I haven't seen any advice yet that was intentionally put here to cause harm, but it could if the advice taker just does it without further investigation. And next time, I'll wait for someone with much more vast knowledge and understanding of the inner workings of pc's to give the first answer so there won't be any hard feelings because one of us dummies got there first with a stupid answer.

What an interesting conflict. Dont write things on message boards if you dont know what your talking about, or at least state that that is how you think that somthing works . Dont state it as fact. Besides overclocking is quite simple it involves a coat hanger hammer and a ruler, write me for free plans.

i believe that you can only overclock the cpu if you have a digital display on the front of the pc, simply change this from say 100 to 166 and it will be 66MHZ faster

none pentium II cpu's over clock on motherboard. There is a list on MB that shows clock speed, and another that shows FSB (front side bus) Over clocking can be done a number of different ways. First is to increase the FSB for example 60 mhz to 66 mhz. when increasing the FSB it will also increase the PCI bus. PCI bus runs at 1/2 FSB. There is a larger performance increase using this method. Problem is not all pci devices can run above 33mhz, so increasing FSB beyond 66 may cause problems including a lost of data on HD. a 75 mhz bus will run PCI bus at ~37 mhz. a good test of seeing if these new settings will work is one: what is your bios reading your cpu speed. IF there is a non rounded # at start up such as 198 instead of 200 it did not work. Second is the ability to boot into windows without error messages.
If your system runs windows and crashes after some time, increase your cpu cooling by adding better cpu cooling, leave computer case off, or add additonal case fans. Then run again, cpu's typically need "burn in time".
Second way to overclock is to increase clock ratio. for instance 2x to 2.5x, this is done on your motherboard and it will have a chart listing clock ratios and jumper pins. this will give you and increase of performance of 133 - 166 mhz. Because of the large increase this may not work. You might want to split the difference and go for 150 mhz by decreasing your FSB to 60 MHZ and 2.5 clock, (for example). I recomend that you try increasing your FSB first, larger performance gain. On your MB there is a chart showing your clock speed or FSB and jumper settings. if there is not, try to get a manuel over the net that shows the proper settings. Don't do any over clocking with Cyrix cpu's. I have a Pentium 166 running 200mhz with 66 mhz fsb. a pentium 150 running 190 mhz at 75 mhz that runs almost faster than the 200. Amd k6 266 running 300 mhz. and a Pentium Pro running 150 running 180.
This only do with extreme caution: running cpu's at a higher FSB means they need more voltage. Try increaseing voltage, (example) 3.2v to 3.5v. make sure that you have great cooling. large MHZ jumps can be gained from this mothod. I currently do not recomed this method and I don't use this method.
For PII and PIII, Celorn:
internal clock speed in constant and cannot be changed. Therefore you can only change the FSB. Cooling becomes important, because the Celeron has no case cooling becomes more effective, making Celeron a better over clocker. IF the FSB is 66 mhz increase to 100mhz, so a PII 266 will now be running 400 mhz. Newer PII are better for this because of the newer manufacturing process. Because of the ram you must have PC100 ram for this increase. For II-III's pci bus is divided by 1/3. so change in bus is less significant. voltage can also be increased on some MB's. For overclocking PII's and PIII's change bios. All settings for shadowing or caching of video, ram must be turned off. All SDRAM timings should be set to lowest possible numbers. Set 8 & 16 bit I/O recovery speeds to maxium numbers, ( 4 and 8 respectively).
this is all I have to say!!!

I get alot of customers with this desire. I own a computer store. Get yourself a ABIT Motherboard for PII CPU's, use celeron 300-400 MHz CPU's. In your set up Bios, you can over clock your CPU easily without hurting your Celeron Chip or Motherboard. It's best to stay within your Bus speed. If you are using celeron 66 MHz stay with the same. For instance: Celeron 300/66MHz bus can be clocked to 400/66MHz etc.

Does any one here take computers seriously?I go to ITT technical school , and have builed a few systems , they say that you should not over clock your cpu because it creats more heat. whithin the cpu (central processing unit) are many switches , that switch curent alowing the cpu to function. Many older boards had jumper setings on the board for the cpu voltage ,and clock speed ,but with the boards of today the cpu settings are usually in the cmos setup. If you do over clock your cpu remember that it will creat more heat and there for shortening its life.Use a better ball bering fan

Hi
As I know so far, you can only over clock you cpu a little or it might over heat. You can find lists of how much you can over clock your cpu, by searching the internet. After you got the "list" (very importen)of your cpu you will find how to switch your jumper on your cpu user guild. It will look something like this (this is just Eq)
(Up= no jumpers down=jompers down)
166 up down up up
200 down up up up
233 down down down up

I've just got hold of a Cyrix Media Gxm 233Mhz which I'd like to overclock to 266Mhz.
I've heard all this talk about Cyrix being bad for overclocking but has anyone got any
ideas on this machine? The bios gives no access to bus speeds but it (supposedly according to the board manual) will support 266Mhz on 66Mhz bus 4x. I have tried this and
no joy! How the hell do you change bus speeds
that can't be accessable from the bios? Any ideas?

this may be old news now, but i have noticed everyone getting mad with one anothers opinion about overclocking and how soem say not to and some say sure go for it. the truth is, almost anyone can who has a little experiance with computers can overclock almost ANYTHING. The secret is COOLING your CPU. Sure overclocking can be bad for your CPU but with the proper cooling system there is no harm in it if not taken to extremes, and yes, even for CYRIX. if you want to learn more about overclocking go to

http://windrivers.com/dir/scripts/dir.asp?cat=Overclocking&t=Overclocking

for more information on cooling i suggest you read up on these guys.

http://www.frostyfox.com/
http://geocities.com/Heartland/Flats/1045/celeron.html
http://www.brazi.net/cooler/

they even have pictures of thier "experiments" to prove it can be done safely....most of the time. but as any project goes, things can and do happen. So if you dont know much about your computer or dont feel comfortable popping off the case and getting inside with a soldering gun or even changing jumpers i would suggest you just buy a faster computer and leave the "Tweaking" to the confident :)

Hi All
I have a Celeron 300 A
the motherboard is a Pentium II M729 by PCChips.
the bus speed is on 66 4.5 for a speed 300 MHz
All fine.
Now when I move the jumper from 66 to 100
and try to boot I see it say Celeron 450 MHz
then gos black and never boots.
What do you think???

the core voltage is set by the board I think.
How would I do that with this board.
Also do I need to do the pin 21 thing with this C 300A
when I do the jumper on the board change it from 66 to 100
bus then put it on I do see it say Celeron 450 MHz
but after that it gos black.
So do I need to do the pin 21 with tape too??.

Thanks

overclocking your cpu is not necessary. all you need to do is think and act slowly for one day without using your pc. next time you get on, it will be (seem) so much faster! it also helps to avoid running any programs that require more than 8 MB RAM.

personally i have a Cyrix MII clocked at 333mhz i cant get it any higher or it says its a lower speed, i have occasional heat problems on a hot day which i overcame by buying a new AOPEN case, which allows for a fan in the front, i use this to extract air and another one (12cm ball bearing) screwed in blowing air on the video card, this seems to work good and i can also over clock my banshee no problems to 130mhz
the case is the HX-45middle tower system which i personally think is an overclockers dream case, i got 3 fans and tonnes of room left i could even fit another 2 12 volt if i really wanted too...
oh and is there any way to clock the cyrix above 333mhz, my motherboard supports 66, 75, 83, 94?? 100mhz bus speeds, and multiplyer up to 5x also what core voltage,

Which would be able to run at a higher speed,
a K6-2 300 or a K6-2 333? The 333 runs at
95Mhz bus, while the 300 runs at 100Mhz bus.
Could the 333 be overclocked to run at 100Mhz bus? Then maybe run a multiplier of 3.5 for
a final CPU speed of 350? Or should I just go with the 300/100 and try to run it at like 105Mhz bus w/3x multiplier? Price is not an issue between these two chips. Please email.

My p133 non-MMX Intel CPU Will not overclock more than 166 MHz. When I put it up to 200 MHz it comes up with a windows protection error. I know i Have enough cooling so over heating is not a problem. Is there a program that overwrites this protection error? Or can i do something else?
Any replies would be Great!

Mech3M December 18, 1999 at 06:39:19 Pacific

Tips for the Frustrated.

There are two options:
The heat is problem. You can't set you CPU to higher voltage(NonMMX=only 3.3V)(the stability could be reached by increasing the core voltage or cooling under chip temp. spec.). So you must have better cooling for your CPU(peltier cooling). That's the one option. It exists a program named SetFSB(you can set the frequency within Windows)but it will not function with your motherboard(old mobo).
The second option: could be problems with the frequency and your RAM(you have SIMMs = EDO RAM or FastPage RAM or DIMMs = SDRAM). EDO RAM,FP RAM and SDRAM66 may work with 66MHz(your frequencies could be: 50,55,60,66,75,83,... and multiplikators: 1x-5x...). Above 66Mhz they could make these protection errors. The solution: Try to go to your BIOS and set the "RAS to CAS" from "2" to "3". With SDRAM100 may not be any problems. Bye.

Geez, what fat-headed fucks around here!!!
Im only 14 but have quite an extensive knowledge of computers and overclocking but I don't shove it around like some nasty fuckhappy moron!!! (This applies to that ITT braggy sonnovabitch.)

Anyways, My Celeron 466 has been running at 583 for 4 months now. I don't suggest OC'ing with a jumper motherboard. I have an A-bit BE6 and just raised the bus speed from 66 to 83. Since processor speed is determined by the 7 multiplier and the 83 busspeed, I get 583. I also had to increase voltage for the chip to 2.2 up from 2.0 in order to improve stability. No jumpers, it's just scroll and select from the bios menu.

As for cooling, I purchased an ALPHA heatsink w/ Y.S. tech. fan. I tried 583 with the stock intel H/F. It ran at 47c. Far from bad considering that intel says 70c is the maximum temp. the 466 should run at. But, after installing the new heatsink and fan and applying thermal compound, the temp went down considerabley to a cool 34c. Also, installing the new H/F let me drop voltage to 2.2 further cooling the chip. Even brought my case temp. down, too. I also installed an intake case fan, and a slot-fan under my Voodoo3 to help out with the case temp.

If you get a Celeron 466 and want to overclock it, I suggest the following ones for they OC rather easily to 583.

SL3FL
SL3EH
If you plan on OCing, look into A-bit motherboards for they let you set the Front side bus and the core voltage.

If you want a good site to check out, goto
www.overclockers.com
They have a cpu database that shows what are good batches of proccessors that OC easily, also, they have many links to Overclocking Guides and FAQ's.


I hope this helped some of you!!

heheheh its funny reading some of the things people say...
anyway.. there were a few people who got things right... you overclock your cpu by changing the bus speed of the core voltages... althought on the pentium III becuase the people at intel are assholes you cant change the core voltage and can ONLY rely on bus... this isn't all that bad though.. i got my pentium III 450 running stably at 504mhz.. there is a risk to overclocking though.. as somone else explained.... i may as well tell you.. a pentium III-450 does not like running at 628mhz.. it actually booted up.. ran fine.. i went into windows.. god damn it was fast.. then i rebooted only to find my hard drive screwed... you gotta be a bit careful when overclocking...

the biggest thing to worry about when overclocking is heat.. thats why theres such a vast array of cooling accessories you can buy these days.. and you really should consider them when overclocking.. a friend has dual celeron 300s running at 700mhz fine.. he also has 3 inch holes all over his case for some of the 14 fans within his machine...

celerons are known for their over clocking ability although the newer ones cant be overclocked (so i hear). amd's are also good for overclocking..

to overclock find out first off how you change things like the bus speed... either by finding a manaual for your motherboard.. downloading of the manufacturers websites.. or experimenting.. its often written on the motherboard... jumpers are the normal way of doing thing but these days "jumperless" motherboards are coming in... of two types... some simply have switches instead of jumpers on the motherboard.. (a bit of a scam by manufacturers) and some rare ones can be changed in the bios.. although they seem to be rare enough for me not to have come across them...

generally speaking i think anyone would be crazy not to overclock as its seems completely safe to overclock by 10% on any machine.. and to deliberately run your computer slower than its capable of seems stupid but at the same time.. i can attest that it does rather suck when you lose your hard-drive... if your gonna overclock a lot.. do it before you have anything on your hard drive (or afters its been backed up)..

Hot OverClock January 26, 2000 at 23:17:23 Pacific

I have a pentium II 350 running at 467 with no extra cooling and it stays stable temp around 34c simply by upping the FSB to 133, this will conflict with a lot of devices sop there can be playing around. I740 ago cards love it though, the performance is comparible to a 32 mb tnt2 speed wise.
What i want to know is wether there is any possible way of removeing the multiplication block in the pIIS coas i wannt to change my multiplier to 8x as my motherboard supports this.

Nick January 29, 2000 at 17:11:53 Pacific

You can change the core voltage multiplier on the PII's, but trust me it is not a good idea. I have a PII-350 myself (a SECC-II even, which is supposed to have better cooling) which I only pushed up one notch (to 4x) and a couple of months later found myself needing to buy a new power supply and fans as my computer had overheated and burned them out. It killed my CDRW too, which pisses me off because it was only a few months old and Memorex wouldn't let me return it. Now I have four fans in my case and am just overclocking the bus to get it up to 392mhz. I'm sure I could put it up higher than that since it barely reaches 90 degrees now, but I am never again changing the core voltage after all that.

I damn near peed myself reading this. I suggest before any of you try to overclock your PC you start with simple things. Turn up your fridge. Tighten your lug-nuts. Run around really fast. Did you get hot? You did! Point a fan at yourself and run around some more! Then go to www.hardocp.com or, say, www.overclockers.com. And do it really fast! It's good practice!

Overclocking Step by Step

Turn off computer, open it up, get your motherboard manual
Check your CPU markings on top and bottom of CPU, write them down and put your CPU back in again
Check the current clock speed and multiplier jumper settings on your motherboard, compare them with your manual, write them down
Check the supply voltage jumper settings on your motherboard, compare them with manual and your CPU marking, write it down
Have you thought of a decent cooling for your CPU ? Apply it !
Change the jumper settings for clock speed and/or multiplier according to your manual
Check if everything is ok, no jumper forgotten or put wrongly
Start computer
Does it reach BIOS setup ?
If yes, go to 13
Turn off computer and change jumper to higher supply voltage according to manual, if possible
If you still shouldn't reach BIOS setup, forget about overclocking to this speed
Change BIOS setup settings to the right values
Does it reach full working operation system ?
If yes, start testing (I recommend Winstone or the BAPCo Suite. Don't take this job too easily! It's better to occur crashes or lock ups now, than coming across them when it counts!)
If no, you should try 11 or check your cooling, you also can try some more conservative memory timings in the BIOS setup. This means increasing the wait states or the read/write cycles; but don't forget to check later if you gained speed by trying some benchmarks, cause there's no point in overclocking if your memory access is getting slower.
If everything works well - congratulations, if not, try 11, check cooling
Don't change supply voltage unless you have to. It only makes the chip hotter.
Never forget: cooling is of main importance !

I work in 2 p.c. repair shops and have built many p.c.'s and upgraded them as well so as far as overclocking your cpu it is not recommended but if you do only over clock it by 50 or 33 no more few boards do this by the bios but not all boards do you get into the bios by the delete key some are the f1 or f10 key as well but alot of boards clock the cpu by jumpers on the mother board you should have a schematic on the board to tell you what to set them to make shure to tell the diff between the hz speed and the multiplire and know that some boards dont even let you over clock some detect and configure the cpu by themselves becouse people kept overclocking the board and burning out the proccessor

hmm,
you guys seem to know something about overklocking...
I klocked my pIII650@100 Mhz to
910@140 using the via apolo chipset and the standard 1.65 core voltage.
I just wandered if someone got his CPU higher (for example 988@150)
I can't because my memory can't take the 150 Mhz. So if someone succeeded i might get some good 150 Mhz SDRAM

Okay I know pretty much nothing about clocking, I have a pentium 133 but for some reason its woirking only at 100. Now I know that you can over clock it to 166mhz, on my mother board it shows 100mhz 75mhz 90mhz and these two jumpers BF and MREC CLRPASSW. Now what do I do, how do I change the voltage when I goto the panel when the cpu starts up f2 I do that now what??

Stephen January 1, 2001 at 12:43:21 Pacific

man... where do all of you come from... ITT says not to overclock your computer - it must be true, that's the best computer school in the whole world... (I'm a computer engineering major at Texas Tech). There are two things that affect your processer speed - your FSB (front side bus) and it's multiplier. Celeron's have a FSB of 66 MHz, PII's are 66 or 100, and PIII's are 100 or 133, Athalon's are 100 or 133 (if i said or, it's not that I don't know, it's that it depends on the speed a 700 MHz PIII runs on a 100 MHz, a 733 is 133, a 750 is 100, a 800 is 100 a 800EB is 133.) The multiplier is how many times faster than the FSB the processor runs, and usually goes up in increments of 1/2 (5, 5.5, 6, etc). If you have a board with Intel's BX chipset, you don't want to change the FSB, as it can mess up your PCI or AGP cards. Most other chipsets can be changed a little bit. If you do overclock your chip, it can usually be changed either in your BIOS setup (when you press the delete key at boot-up or by physically changing jumpers on the motherboard. (if you can't do either, like on Intel boards, sorry.) If you are going to go more than 10 to 15% over the current frequency of your chip, use thermal grease between the processor and the heat sink, and place one or two extra fans in your case. Some CPU's will over clock more easily than others; Celeron's work very well, since they have the thickness of the PIII's connections, but only run at half the FSB. Early PII's are hard to do, as the overclocking will require more voltage, and usually the motherboard isn't set up to do that. My advise is to put in those new fans, bump the multiplier up 1/2 and run your computer, if you have any problems, you are going too fast and need to go back to the previous multiplier value, if you don't, try going up another 1/2, until you do have problems (make sure your computer can run for a day or two, with the cover on with no problems before you decide to keep the settings.

For the Presario 5304, the mainboard is a Gigabyte chipset SIS.
Verify the exact model on the board, near of the IDE connector and the Rev. near of the last ISA slot.

I had found the documentation about the switch setting. By heart SW1 1,2,3 should be off for 3.5 ratio the default is On.On.Off = 2.5 (2.5*100=250Mhz)!

Good Lock!
