Upgrading a Slow CPU to a Faster CPU

Hi,

I bought an old Packard Bell "Multimedia C115" desktop computer from a
friend of mine for $20.00. While he had it, he did a some upgrades (128M
ram, USB ports, etc.). It has Windows 98SE.

The Pentium processor speed is a 120Mhz. I would like to upgrade that to
at least 200Mhz.

Besides changing the CPU, what other changes would I have to make?

Thanks in advance, Brad

Hardly worth the bother. Assuming you could even *find* one that old/slow.

None as long as your motherboard will work with whatever CPU you get.

What dadiOH said. See if you can get a manual from some website
(Google with /exact/ model #) to see up to what speed CPU your
MB will accept. You can probably get it free or for $3 from a
computer repair shop - they often have a box of under-1GHz chips
just sitting there gathering dust. I don't /think/ that it would
harm your machine, so if you can't find out /what CPU/ your MB
accepts, you could just take a few chips and keep going up until
it stops working. But damage /could/ be done I suppose, maybe
someone more knowledgeable will comment.

That could end up being quite a nice machine.

Just check the jumpers.
if the boar can be jumpered for a 200mhz cpu...
it will work.

Win98se will work better with a 200mhz cpu
 
Re: Upgrading a Slow CPU to a Faster CPU

The changes required would be quite extensive. The speed of a CPU is the
maximum clock rate that it can run at, not the speed at which it actually
runs - that is determined by the motherboard it's plugged in to. You need
to confirm that the motherboard you are using has the ability to run the CPU
at that rate, and that you can find the necessary documentation to change
the clock speed to whatever the new CPU can handle. On a machine of that
vintage there's probably several jumpers to change. Often, changing the
clock speed also changes the memory access speed, so you will need to ensure
that the memory can also cope.

If you really want to upgrade it, it's probably easier to find a faster
motherboard with CPU installed and configured than to replace the CPU in the
existing motherboard. My local computer store has a bin of recycled
motherboards removed from working machines (not guaranteed, but very likely
OK) that sell for a few dollars each.

Hello:

I work on a lot of vintage Packard Bells and the boards are proprietary
so replacing the mobo with an AT or ATX type would not be possible. Most PB
P1's
are easily jumpered to 200mhz and no RAM changes are required...
A good flashlight and reading glasses may be needed...but...
It's an easy ten minute job...and for win98...going from 120 to 200 mhz
makes sense to me>


OTOH: If you walk out into the street, chances are there's a pitched out
P-III sitting
there that was tossed because the owner left a floppy in the drive ! <G>

Huh? Who mentioned AT or ATX?

You specifically stated that your local computer store has a bin of used
boards.

The so called "surplus bins" present in computer stores generally consist
of boards from machines that have been upgraded, or perhaps new , old
stock inventory etc.

It is very unlikely a used motherboard bin would have a proprietary
PB motherboard...but if they did have one that would in-fact fit the
OP's machine...it would simply be a very similar board to what he
already has.


Though most any AT or ATX machine can be a possible candidate for a mobo
upgrade...the PB's do not fit into that category due to the proprietary
nature of the board.


Of course...I have occasionally done a few major modifications...
and recently did take a nibbling tool to an old AT style cabinet
and get a proprietary board to fit in there...
No rational person would go through all the trouble that I will
often go through just to save some old equipment <G>
