Hi,
I have a Chaintech CT-6BTA3 440BX/ZX motherboard with an Intel 450MHz PIII (SL35D).
What 1GB+ (2+ if possible)CPU can I upgrade to?
I am confused by the socket type (1 I think), package type (pin SECC2 OLGA1), BIOS etc.
Thankyou for any assistance!!
Rupert.

You have the earliest PIII 450 with 0.25 micron technology. Since, Intel introduced .18 and .13 micron chip. It is unlikely you could just upgrade the CPU only with any gain in performance. Your motherboard (chipset) is 2-generation behind anything that could run over 1Ghz.

Besides, everything else in the box is getting old; power supply, CD drives, hard drive etc. And, likely it has only 200 Watts power supply. You'd better off getting a $400 deal from Bestbuy and you would have an up-to-day unit. I figure you are not very savvy in building your own system, otherwise you would have gone for P4 Celeron or AMD xp for less than $200.

XP1800+ chip $64
Board as low as $50
PC2100 $50
Cheapo case with 300Watts PS $35

P4 Celeron 2Ghz $60
Board as low as $50
PC2100 $50
Cheapo case $35

sorry, but your motherboard can only support up to 600mhz pIII/celeron processors.
the faster pentiums/celerons today run on 478 or 370 socket types. if you want a 1ghz or faster cpu you're gonna have to upgrade your entire motherboard.

heres a link to the product description

yeah you're probably better off getting a new system

Powerleap upgrade PL-iP3/T

Performa - Slot 1 Upgrade - 100 MHz FSB

With a slot1 to socket370 adapter you can go beyond that 600MHz.
The Powerleap adapter sounds quite good and it allows you to use up to 1,4GHz FCPGA2 socket370 pentium3 cpus.

There are a lot of other adapter cards out there but normally they only allow the use of FCPGA cpus and the latest of them is the coppermine core pentium3 and celeron with up to 1,1GHz.
I have an Asus P2B Rev. 1.04 slot1 board and upgraded from a 350MHz pentium2 to a 733MHz celeron which is now overclocked to 1232MHz. I used a MSI 6905 Master Version 2.3 adaptercard because my board didn't allow a cpu voltage below 1,8V. That adapter has jumpers to make the board believe that my 1,75V celeron is now a 1,8V cpu, otherwise the system wouldn't even start.
But with a Pentium3 already installed that shouldn't be a problem and the powerleap adapter should also deal with such problems. But better check the compatibility information I think I saw somewhere at www.powerleap.com!
Also check if you may need a bios update and if there is such!

BTW:
I would have bought that adapter myself if I had know at the upgrade at the beginning of this year. But on the other hand I decided for the 733MHz celeron out of price reasons. I knew from the net that it should be good for around 1GHz and the real 1,1GHz celeron cost about double of the 733MHz one then and the 1,1GHz pentium3 would have been again double of that.
With the upgrade this old system from 1998 is still good for nearly everything and nearly as fast as my actual main system, a 1,2@1,33GHz Athlon TBird. It's a second system and I use it to play network games with friends, viewing movies on it and all sorts of work that takes a while to finish like compressing movies and so. That way I can still work with my main system!

If you don't want to play the newest high speed games you should be fine with that upgrade for a while and and it should be ceaper than a new board, cpu, heatsink and ram. It's your decission if it's worth it or not!

Guys (?)
Thanks for all the info.
I got my box before the turn of the century, so I was not really expecting too much of a positive response for my quest!

Real_cool - I would have gone for a P4
Celeron, but they came out a couple of
years later! I'll check Bestbuy!

Zaphod (may I call you Zaphod?) -
Thanks for the replies, and the link.

x86 - I have not yet looked, but I'll check
out your link suggestion too.

Free Weasel - Your solution also looks good
- I must admit that this good old (very old)
processor has been fine for the last
4-5 years, but my wife got me Halo for
Christmas, and I need either a new box,
or a new processor and video card - or a games console.

I might just keep this box as a 'server', as
I have installed a network card, and a couple
of extra HDDs and cd writer, so it could
live on as a data-store!

Thanks again

Rupert.
