T20 PIII 650Mhz at 500 ... What can i do ?

Hello there,

I have a T20 PIII 650Mhz ever running at 500. My battery is dead and for what i read till now, i understand that IBM blocks the CPU at 500Mhz when AC on and battery off.

Is that my problem ? Can i do something about it, maybe directly doing a mod on the hardware ?

Thaks for your help,

chau,

Jerome

Hola,

Have you tried to enter the BIOS (Press <F1> on boot), to deactivate Intel SpeedStep ?

If your BIOS is identical to mine, then the option is located in the "Config" > "Power" section.

Yes i have change BIOS parameters several times but still running at 500Mhz ... any idea ?

OK !

Is your CPU recognized as a 500 MHz one in the BIOS, or in a Windows software ?

If you use a software, can you give us its name ?

BIOS reconize my PIII at 650MHz and Win XP at 500Mhz ...

Using Everest or CPU-Z, both find a PIII 650 but at 500Mhz.

Hope it helps for your help !

Thank you

It might be a case of Windows getting its grubby mitts on the CPU. Check the options under "Power Options" and disable the automatic CPU management.

Correction :

CPU-Z => PIII 500MHz
Everest => PIII 650MHz at 500MHz
BIOS => PIII 650MHz

---------------------------------------------------

I've desactivated SpeedStep but doesn't change CPU Clock.

Thanks for your help Vlyne.

Anyone who can help me ?

Saludos,

Jerome

Hmm, I've verified again in the BIOS of my T23.

You must activate "Intel SpeedStep Technology", and set the "On AC Power" option to "Max Performance".

Hello WarMachine,

I've already done that but doesn't change anything ... More, i've tried different combination in BIOS Setup but TP still running at 500MHz.

Thanks for your help and hope someone got a solution, somewhere ....

Vive l'OL !

Get a battery (even a used one), that should solve the problem for now.

Thanks Realblackstuff, but i hoped there was another solution than buying a new battery ...

No mod on motherboard could solve that ?

Thanks anyway.

That's in the nature of the beast, according to IBM specs. No mod available.

Ok, but as far as this is electronic, something must be possible to be done ... Hope makes life !

Thanks RBS,

I had a T20 and remember the original discussions around this. It's a chipset issue, and I don't think anyone ever found a solution. You could try changing the system board for one with a different chipset if you don't want to get a battery

Seriously though - if you are looking to up the speed to improve performance it really won't make much difference. Have you done all the usual stuff - defragged, shut down unnecessary startup programs, etc.? That will usually make a much bigger difference that getting the CPU back to 650 Mhz.

Hi Egibbs and thanks for your comments.

Indeed i've done all the usual stuff to improve performances but i can't even run warcraft 3 on the TP ...

I know that it won't be a revolution if i can go back to 650 but meanwhile i'm saving some pesos to buy a PC, maybe it will run a bit faster.

Thanks all, if nothing is possible so i'm on my way to a bank robbery !

It has nothing to do with the battery.

As far as I can tell this is completely normal. When the CPU is at idle or not at full load, the CPU speed is automatically reduced.

Here is a way to test it. Open CPU-Z and monitor the clock speed. Now open a program that takes a long time to load. You should see the CPU clock speed jump from 500 to 650MHZ when the program is loading.

This is what happens with my T22. At idle the CPU is at 700 MHZ, but when I open programs, it jumps to 900 MHZ, and then goes back to 700 MHZ. My CPU multiplier changes from 7 to 9, depending on the load. I have installed the IBM Power Management Driver, I don't know if that has anything to do with it.

Hi Elite,

What you are talking about is the speedstep technology, which reduces clock speed when notebook isn't under full load. My problem is different as clock speed stay at 500 whatever the load is, because it doesn't have battery's on.

For the Power Management Utility, as i don't have any batteyr, i don't use it so i can not tell you specificaly what it does, maybe something to do with optimized the battery's time .

Thanks

While browsing my BIOS options I noticed something. There is an option to disable speedstep. When this option is selected and speedstep is disabled, the processor works at minimum speed. Did you check that out?
