Need help Overclocking a 700 Celeron.

[Pandagonier]

i have the following:
Asus CUSL2-C Motherboard
700 Mhz Celeron
i have 5 case fans (im notworried about overheating)
192 MB of pci100

now what i need help on is trying to keep it stable....and a few tips on overclocking would be very appreciated. :)

[Carmine_Paterno]

O boy!

I had one of these, and it went to 997 stable @ 2.4v LoL.

It is a horrible overclocking chip. Not only becuase of the 10.5 multiplier which limits overclocking right off the bat, it is because the fsb is soo low the benchmarks will always be horrible. Thats why i got an amd duron, so i can change the multiplier/fsb as i please.

Maybe yours will go higher. Mine was kept very cool also.

[Pandagonier]

i got it to stay at 924 mhz..but i want to take it over 1000mhz.....but if i take it to high..it goes back to 700mhz and when i go back to my bios everything is the same as before,but its reading at 700mhz,why is that

[Endeavor]

you probably have some rogue jumpers to take care of, make sure all the jumpers are set to auto

[ken257]

Sometimes these boards will reset themselves back to default after a failed boot. This saves you from having to clear the cmos after selecting settings that aren't bootable.

What voltage are you running at? What is the cpu temp? What fsb are you at with that PC100 memory? Off the top of my head I don't remember if the C700 runs on a 66 or 100fsb at default. If the default is 100 then your PC100 memory could be the problem.

[Carmine_Paterno]

The Celeron II 700 is @ 66mhz fsb default.

Is it cC0?

[Pandagonier]

my temp is at 145 degrees F.
i have a jumper free motherboard
i run at 1.65 volts

[Carmine_Paterno]

145 degrees is very hot. Lower the heat, and maybe try overclocking.

you usually don't want to go over 40C underload. 38C is 100f.

[Teddy]

Why don't you increase the voltage? say 1.8volts?
If you run it at 924 this menas 88Mhs FSB right? try up to 92MHz not worthy trying more .. One friend of mine has a mother board that can switch the FSB with 1MHz inc. and at 91Mhz his Celeron 633 is stable, at 92 it crashesh but he set the jumpers directly to 100 and it ran purfectly. What is your mother board? I suggest you inccrease the voltage try up to 91-92Mhz FSB and if at 91 it runs stable directly switch to 100 I'm sure it will at least post at 100FSB it will give you 1050, if it crashes at that speed try increasing the voltage again but don't go any higher then 2 volts. You must have a very good cooling if you increase the voltage!

[Carmine_Paterno]

i dun think he should start to o/c that cpu until he cools it down. Don't want to kill it now!

[Pandagonier]

i`m not worried about killing my celeron..i have another just like i...actually i have the the same one

[Mr B]

Still doesn't make sense to kill it because you can, though. Even if you take the case side off and point a window fan at your rig.... do something to get those temps down a bit. Especially before rasing the vcore any more that where you're at.

Yeah, you might fry the Celeron, but what if it gets nasty and takes the mobo with it?? Stranger has been known to happen.....

[Carmine_Paterno]

I used to think the same way. So what if i kill it, i can always put back in a spare chip. Trust me....That kind of ignorance can make you loose your whole rig. I have learned alot since being in this forum. I have also matuered alot, so i don't try as hard as i used to.

Don't get me wrong, trying hard is not a bad thing, just you have to know your limits, as well as the computers limits. If you take the time, lower your temps, and read up on others instances, you could have a decent overclock. I have killed 3 chips in my time, and i really don't want to fry anymore.

I am here to help you, as are others. I have come a long way from being baffled why i wasn't able to change the multiplier on my Celeron II 700, to now being able to help people in need.

Trust me....frying the chip isn't worth it. It is a waste of a chip that could be good. Just run it @ 700mhz, and lower your voltage to around 1.65v. That should get you a decent temp. Try burning in.

Get some better cooling like from here.....the best place around!

Best prices, best quality. I know the guy, you can trust him. I recommend the svc golden gate. Get that, some Artic silver 2 and you should be on your way. I think we could get you running to at least 900.

Everyone is great here, and on behalf of all of us, don't kill the chip, just be patient, and give it some time.

[Pandagonier]

so if i lower the temp i will be able to go higher....
if i run at 700mhz and with the v core set at 1.65 my temp is still 140 F......
what is "burn in"
if i change my ram to pci 133 would it make a difference in OCing

[Carmine_Paterno]

If you lower you temps, yes you will be able to overclock higher.

when you say your tempature is 140F, is that at load or idle?

Load is when your computer is "stressed" or being used like by playing a game.

Idle is when your computer is just sitting there.

Burning in is when you are putting your computer in "load" for a certain period of time. I use sisoft sandra burnin wizard because so far, it has made my temps the highest i have seen, and i can set how long i want to run it for.

What heatsink/fan are you using? If you are using the standard one, buy some thermal paste, and apply a very thin layer on your cpu's die. You should not overclock with the standard heatsink/fan.

Buying Pc133 ram should not make a difference in overclocking your CELERON II 700. Pc133 ram will only make a difference when you will be at a fsb like 120+, because then you can run your ram @ cas2.

There are 2 "CAS" timings.

CAS 2 : Cas2 is when your ram is running optimal (SDRAM)
CAS 3 : Cas3 is when your ram is running slower so that you can achieve faster speeds.

Some ram can run CAS2 @ 133fsb, and CAS3 @ 150fsb. CAs2 @ 133fsb=faster memory.

Lowering the temp makes a very big difference. Also when you report your temps, report them in Celcuis, most people use C instead of F.

Hope that helped!

[Pandagonier]

ok i was digging in my computer parts i have lying around here and i found a orb heatsink...well i put it on my cpu and now i`m runnin at 36 c when its idle
and when i play a game like sacrifice or everquest it goes up to 42 c...

[Carmine_Paterno]

Thats better but, still a bit hott for default voltage/speed. That is still much better.

I am happy that you changed your mind and waited. Its a good thing that you didn't kill your chip. Do you have any case fans? Try changing out the orb fan with another. I think you could possibly drop your temps down to 40C with a better fan. If you have a Power supply (one that you can change your voltage on, not a computer power supply), you can hook up a fan, and up the volts like i did on my 80mm delta.

If you got a 40mm fan going @ 40cfm you could probably get to 38C full load.


GOOD LUCK

[Endeavor]

from what i hear the orb hsf's suck big time

thats what i hear
confirm or deny this please

[Sklathill]

Orbs are okay for Celerons. Look at all the OC'd Celerons in the CPU database using gorbs. Still, that doesn't mean that you shouldn't get better, especially as cheap as some of these higher end heatsinks are. OCZ Gladiator/Golden Gate comes to mind...

[Pandagonier]

so what type of heatsink do you guys recommend.....i`m looking at something under $25.00

[Carmine_Paterno]

SVC GOLDEN GATE

[Pandagonier]

when you say up th volts on the fan....what do you mean by that,and how do you do it...and whats the max temp a celeron can go to till it croaks

[Carmine_Paterno]

When i say up the voltage on the fan, i mean with an external power supply. I have a hewlett Packard power supply that will let me supply up to 60 volts to whatever i attach the red/black wires to. I just turn the knob until it doesn't go anymore and leave it.

When you say until it croaks, do you mean until it dies, or until it becomes unstable.

It dies around 95C+.

It becomes unstable @ 48C usually. At some speeds, you will need to keep it cooler for it to run stable. For example.........@ 700 it is stable up to 60C, but @ 900 it is stable up to 40C, so i will need to keep it cooler than 40C to keep it stable @ 900.

Hope i helped.

[Pandagonier]

thanks for all the help guys.....i`ve gotten it to stay at 924 some what stable...i need more cooling to go further....temp whan max load is 47 c and temp at idle is um....where did that temp go....oh well i can`t find it right now
