Titolo: RTM-Compaq 1621 CPU Change

Ok I took a big swallow of  coffee and opened my laptop. I found the AMD
K6-233 was in a ZIF socket.
My question is can I replace this with an AMD K6-2 266 or 300? If not, will
I see even a little performance increase with a K6-2 233w/3dnow? I did not
see any jumpers to switch but I could not see the whole board. The CPU is
real easy to get at.
    Also, does NeoMagic make a better video card than the 2meg 128 bit I
have now and can it be swapped also?  I am not asking much. :)

Sorry RTM, It's probably a no-go on all fronts:
(1) Your present chip is from the .35 micron production run (166, 200, 233)
and is specified to run with a 3.1 core voltage and 3.3 external.
(2) 3DNow is only an asset when the software you are using has been
optimized to utilize it.
(2) There's no such thing as K6-2 233w/3DNow.  The 3DNow feature was tacked
on to the .25 micron chips (K6-2).  They made their debut at the 266MHz
speed and are specified with a core voltage of 2.2 volts.  You would need to
have a motherboard that supports this voltage in order to do this
incremental upgrade.  BTW - Going up one notch (266) or even two (300)
rarely makes sense.  The differences when running applications typical to a
laptop are barely perceivable.  I don't know the answer to your video card
question but IMHO you have an adequate card already.  If you want to be a
hot-rod computer dude, stick to desktops.  Laptops are best left in their
original configuration and replaced with a complete new machine as required.
If you post again, please include more particulars like brand name, model#,
etc.  It's possible that someone in this NG has hands on experience with the
type of machine you have and could give you more than the general response I
did.

i doubt anyone has experience with this model as I seem to be the only one
who has it. Also, i have a P2-400 desktop "hotrod" for gaming but I take the
laptop to work and out of town so I wanted to hop it up a little.
I guess I will have to live with it. Thanks.

   Well, Compaq is real good about putting growing room in thier
machines and the ZIF socket should be a clue that it is upgradeable. ZIF
sockets cost considerably more than other more permanent methods of
attachment. I suspect that you may be able to upgrade but I think
you're  going to have to be a little  more specific. THings you are
going to have to check out.
1. BIOS. Does the BIOS support anything else. Is your BIOS flashable?
2. Where the #$@#$@#$@#^&&*& -er's at Compaq put the flippin switches
for the timing.
3. Voltage check! make sure that whatever you are upgrading to matches
the power outputs of the board. OR, if you have really big balls
consider modifying the power regulator...... oh, and make sure you get
your amperage right as well.....
4. If you absulultey have to, change the crystal.(timing crystal) just
make sure you did your math right when you run the calcs to figure out
what your new crystal should be.
Good Luck!
shiny side  up, eh?
