CPU Speed showed in My PC Lower than real one.

You can't upgrade the processor: it's already at almost maximum and you can't change models - different socket. The maximum RAM you can install in it is 512 MB of PC100 SODIMM-SDRAM so the speed difference will be negligible.

Upgrade Extended Memory

Ok. Fear not. You CPU is running at its native speed, it is the fault of Windows reporting the actual CPU speed. If you stop in the BIOS, the real speed will be reported there, the same if you run Linux.

No, this highest the P-II went to was either 400 or 450 Mhz. Upgrading a thinkpad CPU may be difficult. Considering prices on used laptops now, I wouldn't think it would be worthwhile, either.

Max CPU for IBM T20, 21, 22 is Pentium III FCPGA2 1000MHz (1GHz). Max memory is 512MB (2 x 256MB PC100/100MHz). Max hard disc is 250GB ATA. Newest BIOS is from April 2004 at the homepage Lenovo.

your board is compatible with pentium 3 processors through the "coppermine" revision, the pentium 3 "tulatin is not supported" here is a list from wikipedia of the "coppermine" processors supported by your board.:



Coppermine

• 100 MHz FSB: 500, 550, 600, 650, 700, 750, 800, 850, 900, 1000, 1100 MHz (E-Models)
• 133 MHz FSB: 533, 600, 667, 733, 800, 866, 933, 1000, 1133 MHz (EB-Models)

Coppermine-T (the only coppermines with an attached heatsink)

• 133 MHz FSB: 800, 866, 933, 1000, 1133 MHz

The Tulatin core is NOT compatible with intel 810 boards, and they can be easily confused with the coppermine-t's because they also have attached heatsinks.

Your limited with the T20 series, the biggest you can go is 1ghz. Try the Pentium M chip, make sure that it's the same mhz (frequency) that's in it now, the board frequency matches the processor frequency. (either a 100 mhz or 133 mhz, you can tell by what memory it uses PC100 or PC133)

hi
your sys is really so good.
check in task manager identify some unknown proess .
they are virus.
clean all temp files.
disk cleanup run.
scan your sys with avast,quick heal ,symantec one bye obe with update definition in safe mode.

then u get some malware and viruses.
then delete it.
after that run chkdsk utiliity.
then defragmen all drive
now your sys really speed up.
best of luck my friend.

I currently own 3 Thinkpad T-20 Laptops. They all have a 700 mhz processor in them, and so will yours, more than enough to run windows xp, in fact, I am running Windows XP Profession on one of them. The PC100 is the type of memory it uses, not the processor speed. i recently installed a 120 gb drive in one of them so you will have no problem installing a 20 or 40 gb drive, or larger.

boot it up to BIOS screen now and look at CPU settings. It may tell you the maximum speed.
