Intel Celeron Overclock help

post #1 of 6
Thread Starter 
I have an old system (not build by me): Jetway mainboard P4M266
with an VT8751 chipset, and a Intel Celeron at 1.7 GHz.

I would like to raise the CPU frequency from 1.7 to 2.0, but I cant do it.

When I change the multiplier from 17x to 20x nothing happens, even if I change
it to 1 or 30 its the same frequency detected by Everest and CPU-Z.

I raised the CPU voltage to 1.8 from 1.5, but couldnt overclock it.

Can you guys please suggest me a way to overclock it. Are there jumpers
for my mainboard?

Please consider that I am newcomer to this area

I hope I posted in the correct area.

Thanks. Any help is greatly appreciated.

You have to find someplace to increase FBS which is normaly 100 and try to increase that. Change the Voltage back to 1.5 or else you will kill you CPU.

I will get the voltage back to 1.5.

How can I increase the FSB from BIOS? Or from mainboard. My mainboard is so obscure that
I could not find anything about this on their site.

it should be same place where u changed the volts for the CPU.

Is it in a prebuilt system like a Dell or something? Some motherboards won't give you the option to raise the FSB in the BIOS. You could try ClockGen or SoftFSB. They are software related overclocking software.

I rebooted and this is what I got:

In BIOS menus:
VddQ Select = 1.5 Selected(default) (1.6 was Max)
+2.5 V Select = 2.5 Selected(default) (2.6 was Max)
VDiMM Select = 2.5 Selected(default) (2.8 was Max)

Host/PCI Clock at next boot is 200/66 MHz (this was the maximum I could set)
DRAM Clock at next boot is 200 MHz

Autodetect PCI/DiMM Clock = Enabled


I changed the multiplier to 18 and the frequency remained 1704.

Those are the most relevant fucntions from my BIOS. What I can
change from those voltages to raise the FSB?

Edit: It was not prebuild.
Edit2: Those 2 tools did not worked.
I will try those software FSB tools too.
