I have this old computer (ca. year 2000) with a Tyan S1854 Trinity 400 as
motherboard. What is the fastest Intel CPU still available on the market
that I can mount on it? (Currently it has a Pentium III 800MHz and 1.5G of
memory.) I went to the Tyan web site and found a chart with recommended
CPU's, but due to my limited expertise in this field I cannot figure out
what they are talking about...

PS: I am not interested in swapping the motherboard for a newer one, or in
overclocking the CPU that I currently have.

Thanks for your help.

I have one with a P733Mz in it, friend has one with a 1Gz. Have a saved post
from awhile ago docs using same. Is the hassle worth it for 200Mz is my
question?

Dear Tiziano,

it looks like 1Ghz is the maximum, and, how much faster you can get from
your current 800mz depends on the board revision:

600EB-866EB
*** 933-1GHz ^

***
Older S1854 board revisions with marking "9900Y" or "9900YA" (next to
the power supply connector, see ( image ) do NOT support P-III flip
chips due to CPU change after initial board production. Older revisions
will only support Pentium® III slot1 processors up to 733 MHz

^
Pentium® III 933MHz to 1GHz (.18 micron) support applies to S1854 board
revisions with marking "99PON" (please refer to the issue above for mark
identification location) and have motherboard revision marking of J or
above. (Look on the edge of the board located by the IDE ports for a
small white box where revision letter is indicated inside)

Here is one P3 1Ghz for $135.

And, for $119, free shipping:

Great information, BC! Thanks for having gone the extra mile in helping me!

Assuming that I have a 99PON, rev. J (or above) kind of motherboard, do you
think that I could safely install a Pentium III 1.40 GHz, 133 MHz, with a
form factor of FC-PGA2? (The 1.0 GHz recommended by Tyan has a form factor
of FC-PGA. I am not sure what the difference is between FC-PGA and
FC-PGA2...)

Thanks again for your help.

Unfortunately, no. To use a car analogy, it would be like trying to put
parts for a 1990 Honda Accord engine on a year 2000 Honda Accord engine:
they are going to be similar, but not interchangable.

From:

http://www.tweak3d.net/reviews/intel/tualatin/

***
While the Coppermine was manufactured using a 0.18-micron fabrication
process, the Tualatin introduces a first time ever 0.13-micron
fabrication process. The Tualatin is Intel’s test mule for using the
0.13-micron process before the P4 Northwood goes into full production to
make sure everything goes well. Utilizing the 0.13-micron process, the
Tualatin is able to achieve higher clock speeds while using lower
voltage compared to its Coppermine counterpart.

Let’s compare the differences between the 2 processors.

Not Just a Speed Increase...

Processor Coppermine Tualatin
Fabrication Process 0.18 micron 0.13 micron
L2 Cache 256k Full Speed on die 256k Full Speed on die (desktop),
512k (server)
Voltage requirements 1.65 1.475
SMP Compatible Yes Server version only
Packaging FC-PGA FC-PGA2
Available Speeds 533-1000mhz 1.13, 1.2 GHz (desktop), 1.13,
1.26 GHz (server)


Looking at the chart, the first difference you’ll most likely notice is
the die shrink from 0.18 to 0.13 micron like I’ve mentioned above.
Shrinking the die allows the Tualatin to use lower voltage than the
Coppermine. The Tualatin using only 1.45v will be able to run much
cooler than a Coppermine running at the same clock speed.
***

So they run at different voltages, which I am pretty sure means that the
FC-PGA2 chip could be cooked by the higher power of the FC-PGA
compatible motherboard.

FC-PGA // FC-PGA2 difference:

So, from what I see here, the 1.0Ghz PIII Coppermine is that fastest CPU
compatible with that motherboard.

Thanks, BC, for such an exhaustive, easy-to-understand explanation! I
really appreciate the great length you went in answering my question.

You can find Pentium III 1ghz dirty CHEAP. Here's the link:

http://www.pricewatch.com/cpu/

There are lots of stores listed there selling any cpu you want.

I once brought a PIII Tualain 1.4ghz for only $47 listed there several
months ago.
