Celeron 950 --- Help !

[kig]

I own a celeron 950Mhz.I run it at 1064(9.5x112)Mhz.
When I try to run it at 1178(9.5x124)Mhz,the pc turns on correctly,
I work without problems for a while but suddenly the computer stops responding.I have 128MB at 133Mhz SDRAM.What is wrong?
What should I do?
Thank you in advance for your answers!

what are you doing when the system stops responding ?.. if you just leave it alone and not use it does it still hang ?

 

[kig]

It still hangs.It stops responding.

use a peltier, raise the voltage or use a 117fsb. nice overclock btw

Is it still working?

It sound like the Heatsink have fail and you have kill the CPU

That is speaking from my Experience.

It works just fine at 1064Mhz.No temperature,no crashes,it's ok.

kig, welcome to the forums!

what are your temps at boot in the BIOS, and once Windows is loaded? If you do not have anything to monitor your temps, I would suggest downloading a program to do that (MBM is good)...always keep an eye on your temps when o/c'ing!

Also, can you give us some more system specs? mobo, hdd, vid, sound, etc...these things are as crucial to a successful o/c as your chipo, and maybe we could help you a little better if we knew more about your system...

Where can I find the MBM?My motherboard gives 124Mhz maximum.I have a 16MB video card with 3d accelerator.
Is there any utility with which I can monitor my video temperature?

 

[Peter007]

That is because your PCI bus is at 41mhz @ 124 fsb

Many BX motherboard have a fix 1/3 PCI divider,

so a 100mhz bus (divided by 1/3) = 33mhz PCI bus.

Howeve, in your case, you overclock to 124mhz

so the PCI bus would be 124/3 = 41mhz!

It is probably 1 of your scsi card, IDEcontroller, sound card, or NIC that is the cause of the shutdown.

I know its not the pci in my case, since everything runs fine at 1/2 pci 83fsb but my mobo chipset cant take 124fsb

 

[kig]

Monitor temperature ?

Where can Im find a program that monitors the temperatures on my PC (CPU,motherboard,graphics card)?

 

[deez]

first what type of mobo do you have? Many BX boards that support 124 and 133 FSB do not actually run very well or at all at those speeds. Also have you tried increasing your voltage at all? In many cases this will help improve stability

 

[Overclocker550]

abit bh6 and voltage does nuttin. im stuck at 112 max, not that it matters since the 350 is the only cpu thatll take more than 112fsb(150, lol)

 

[kig]

Well, I believe that something is wrong with the IDE controller or the video card.How can I determine which one stops responding?
Could it be the hard disk's fault?

If you're only using a 1/3 PCI divider, then go back and read Peter007's last post. It's probably because the PCI bus is too far out of spec. Yes, the PCI cards and IDE controller are on the PCI bus. Also, the AGP bus is usually twice the PCI bus, so that's running way out of spec too, but most AGP cards can handle overclocking fairly well.

I never could get my old BH6/C-566 system stable when I made the jump from 115 FSB to the next higher step either. If you have no options between 115 and 124, then you might be out of luck. Some mobos will allow you to enable a 1/4 PCI divider at 124 FSB. The other option is to go for 133 FSB so that you'll have the 1/4 divider for sure. You;ll definitely need good cooling if you do that. What mobo are you using anyway?
