Overclocking a Celeron 700?

[Endeavor]

is this possible? if so please advise me how.
i have a celeron 700 (obviously) and a Soyo 6vca using a IWILL adapater card (http://www.iwill.net/products/spec.asp?ModelName=Slocket II&SupportID=)

Welcome to the Forum! Hopefully the members can help you with all of your questions to get the most from your system that's possible.

RE you question: Is it possible? Yes. Will you have a LOT of success? Not highly likely. The Celeron2-700 has a multiplier of 10.5x. If you get this chip to 1.0Ghz, then you have done extremely well. With VERY good cooling, you should be able to get into the mid-900s though, and that's not too bad at all.

Good luck and I hope you find this place an enjoyable place to frequent.

thank you for your help,
that leads me to my second question,
how do i do it? i cant get my CPU mulitplier high enough and when i tired the simpliest way (adjusting the FSB) it crashes on me! any suggestions?

[Endeavor]

i just did some checking... my max CPU multiplyer is a factor of 8

[Mr B]

I can't reccomend reading the FAQ's on the front page here enough...the info that can be gleaned there is tremendous. Read thru the topic threads here, as well....lots of valuable tips and ideas.

Ok...that said....

The multiplier on all of the intel chips since around 1998 (early P II and Celeron) have been internally locked by intel. There is NO POSSIBLE way to change it. Irrespective of what options you may have in your motherboard's BIOS, whatever the chip is Programmed to run at, it will run at. None of my boards "officially" support my 9x multi C600...but all of them run it (at 9x, naturally).

In short, the only way to overclock an intel chip (newer than 1998 ) is to raise the motherboard bus speed (FSB). In order to maintain stability while doing this, you almost always need to raise the voltage supplied to the cpu slightly. In order to do this, and maintain stability, you WILL need to increase the cooling capabilities of your system. This means an aftermarket heatsink and fan (hsf) is almost a requirement. IS required, really, but there is always the exceptiion to the rule.

Some chips will overclock much better than others, even virtually identical ones. Each chip is different. I've had a pair of cC0 stepping Celeron 600's....one did 945 MHz @ 1.95v, but no more than, the other made it to 1053 MHz @ 2.05v. There are no guarrantees in overclocking....

Do a bit more reading, and all of this will start to make sense to you....

Welcome to the forums, and good luck in your overclocking adventures!!

Cheers!!

i did try raing the FSB, but then my comp wouldnt boot, i had to reset the bios to get it to work, thats why i dont think the FSB option will work, any recomendations on what to use? i am currently at 66/33x8 i do believe

[Mr B]

Im not familiar with the motherboard you are using, so let me ask the following;

1) What options do you have for FSB settings?
2) What options do you have for cpu core voltage (vcore) settings?? (board and slocket)?
3) What are you trying to get this to run at?
4) Could you post a bunch more info on the other components that make up your system?? This would help us help you a lot easier....

Mr B

http://www.soyousa.com/sy6vca.html for more info
the cpu multiplier is a factor of 10.5 and the fsb is 66 (hence the 700 mhz) and im trying to get it to run at anything above a 700, maybe 800 would be most pleasing

[Mr B]

Ok...let me try again....

What are you using for RAM, expansion cards (ie., vid, sound, etc)?
What do you have the vcore set at?
What are you using for a hsf?
What size PSU...etc....??

I really need more info to help further...

Mr B

i dont know the vcore or pretty much anything else, im just using the defaults for everything and i am an extreme newbie to OC,

i have kingston valueram 128 at 133mhz , tomarrow i will have an ATI Radeon 32 meg DDR ram but presently i have a 3dfx voodoo3 3k and i use USB sound and i have a linksys 10/100 NIC

if u have icq i would love to chat with you about this

[Mr B]

Ok...there is one thing I absolutely need to know before I suggest anything further...

Are you using the intel (Sanyo Denki) Original Equipment heatsink and fan that came with the Celeron?? If you are, we need to very carefully monitor the cpu temp, as raising the vcore will raise the cpu temp quite a lot.

If you have upgraded the hsf, post what it is, if you know or can find out....

Cooling is a priority when overclocking....too much heat is a very bad thing.

Meanwhile...let's try this. Set the jumpers on the slocket for default FSB. Set the voltage jumpers for default, also.

Start it up, and enter the BIOS.... set the cpu voltage for =10%, and the FSB to 100. Let's see what that gets you....

Mr B

[Endeavor]

im using all stock equipment and all my jumpers are default, what exactly do u mean setting the cpu voltage to 10%?

There should be a setting in the BIOS to adjust this...near where you set the FSB setting. (It's been a while since I had my Soyo IN the rig...(I've got a 6BA+III).

Mr B

[Mr B]

Ok...I stand corrected...I've got the manual open in another window at Soyo's site...your vcore is adjusted thru a jumper on the board..(VJ1).

Default is shorting (the jumper is on) pins 1 and 2. Move the jumper to pins 5 and 6. That's +7.5%, which looks like max for this board.

from what i see its called the CPU/PCI ratio and i just set mine to 68/34 which increased my CPU speed to 714 from 700 and its running fine,
i got it to 80/40 which got it to 840 mhz but froze during 2k loading. i got it 1 notch lower, 75/37 which let it at 787.5, same deal with lock, now im at 68/34 which works fine, i assume the CPU part is the FSB then my vcore is always 10.5 unless i change the jumpers

[Endeavor]

i just opened the manual, and now i see what u mean about the vcore, im going to set my bios to default and try this, wish me luck!

[Newbie_Doo]

Mr. B, He has the same motherboard and slocket that I am using on my system.

Endeavor. It is going to be much easier if you go to the Iwill site (or your manual, if you have it) and look at the jumper settings for voltage and only adjust the voltage on the slocket. Adjusting the voltage with the motherboard jumpers is a PITA.

Your Intel retail HSF came with thermal tape. I suggest that you ditch it in favor Arctic Silver (preferable), or the stuff that Radio Shack sells. Apply this instead of the tape after you have cleaned the tape off and wiped everything clean with alcohol.

Your memory should be OK up to 100Mhz FSB.

VooDoo graphic cards suck a lot of power, how big is your power supply?

When you go into BIOS, set up for Optimized settings to start with. After you have put good thermal compound onto your HSF, increase the voltage to 1.80V on the slocket (with the voltage set to default on the Motherboard) and slowly increase speed until you get instability, then increase voltage at that speed until it becomes stable, then repeat.

With a retail HSF, DO NOT go over 1.95V (and I would be uncomfortable over 1.90V). I am watercooling my chip, and I hesitate to go to 2.0V or 2.05V (which is the Intel max spec for this chip). Watch your temps, Celerons tend to get unstable at around 40-45C when overclocking.

E-mail me if you need to, or post here. Good Luck!.

thanks for the tips, but until i can get some thermal grease im going to leave it at 714 mhz, thank you for not bashing the newbie :)

[Endeavor]

i have 250 watt power supply i believe and i will have an ATI radeon (i just bought it and will be here tomarrow if UPS knows whats good for them ;))

I forever consider myself a Newbie. Wear Newbieness with honor and pride. If the technology is moving at all faster than you are, you will always be a newbie at something. G_d forbid that I should be asked anything more than a basic question on an AMD system...I wouldn't know how to respond (unless it was the "pencil trick" question)!

[Carmine_Paterno]

I don't understand why it is giving you suck a hard time to o/c!!! I had a Celeron II 700 cC0, only went to 877 on my ASUS P3V4X (lack of fsb options) and on my new motherboard BF6, it went to 997 (2.3v DON'T DO THIS!!!)

For you not being able to overclock to 75 fsb is extremely odd. Try taking out all of your pci peripherals, meaning modem, sound card, network card etc. Leave in the Video card. Try it at 75 again. Try raising the vcore by .5, it should be @ 1.7, unless you have a cb0 chip, it is 1.65v. cC0 is just a newer stepping, that sometimes, will allow you to overclock higher.

How long have you had this chip? If you just got it, you might need to burn it in. Download programs like Seti@home, folding@home, or prime95 to burn your system in. Also download Motherboard monitor 5 to monitor your temps.

Your temps should not go above 45C, If they do, you need better cooling. I understand you don't have any thermal grease right now. When you get it, you should see a 8C drop! That pretty substantial. I personally don't feel comfortable with anything above 40C, so i have my P3 450 (sold the Celeron II 700) @ 545 1.85v (default voltage was 2.0v) full load @ 31C. Also you might want to try adding some fans to your case. The colder you get the chip the better the overclock.

GOOD LUCK, If you ever need anything, feel free to ask, i am sure Mr. B will help you out great! CHEERS

[Endeavor]

ive had the processor a while so it is pretty broken in,
when i do get some thermal grease i am going to try adjusting the voltage and see where that gets me
