Pentium 133 is such an old processor that i have no knowledge about. But
maybe this can help you:

You already know the bad news - your system has very low performance
compared to any computer manufactured in this century.

The good news is that the CPU clock multiplier is NOT locked on the Pentium
133 MHz.

There may be a jumper on the motherboard to select the CPU clock multiplier.
For a Pentium 133 MHz the stock setting should be 2X, giving a CPU clock
speed of twice the FrontSide Bus speed. Changing the jumper to 2.5X gives
the CPU a clock speed of 166 MHz; changing the jumper to 3X gives the CPU a
clock speed of 200 MHz. Your CPU might work at either of these speeds; it
might not. Increasing the CPU voltage helps overclocking to higher speeds;
unfortunately your system is unlikely to have settings for changing the CPU
voltage.

An alternative to overclocking might be to find a used or 'pulled' Pentium
200 MHz or Pentium 233 MMX CPU; the cost should be around $15 US or less. I
believe either should work in your system; the Pentium 200 certainly will.

Below is a general approach to overclocking; it is unlikely than anyone can
give you step-by-step instructions for your particular system. You will
just have to find and identify jumpers on your motherboard and ask specific
questions here.

Good luck

*****
All Pentium CPUs can be overclocked; some do better than others.

If the motherboard is 'overclocking friendly',
an Intel CPU is very easy to overclock. If the motherboard is NOT
'overclocking friendly' the task is much more difficult. If your
motherboard is 'overclocking friendly' the manual likely gives all the
information necessary to overclock, though the manual may have been
transplanted back and forth among several languages, and the information may
be a bit confusing.

#1. Raising the CPU voltage can destroy your CPU. NEVER raise the CPU
voltage more than 15%, and if you do raise it, do it in very small steps.

#2. Raising the CPU clock speed will NOT damage your Intel CPU,
motherboard, memory, or anything else. If you raise the clock speed too
much, the system will either to run in a stable manner, or will fail to
boot. This is not a problem because either the BIOS will automatically
reset to default values or there will be directions in the manual on how to
reset to default speeds.

#3. In overclocking, make any changes in small steps, checking for proper
operation after each change.

#4. Overclocking works best when the CPU temperature is kept as low as
possible.

#5. Intel CPUs can ONLY be overclocked by raising the clock speed. Even if
the multiplier can be set in the BIOS, changing this settings has NO effect.

#6. Some older motherboards may report an incorrect speed for CPUs that
have a higher speed than available when the BIOS was installed.

#7. Intel CPUs have a quad-pumped memory bus; that means data is
transferred
four times for each clock cycle; for a 533 MHz FrontSide Bus speed the clock
speed is 133 MHz. That 133 MHz clock speed is multiplied by a factor FIXED
and UNCHANGABLE inside the CPU to give the overall CPU clock speed. For
your 2660 MHz CPU, the multiplier is X 20 (133 MHz X 20 = 2660 MHZ.)

#8. The rated speed of the installed memory can limit the overclock.
Memory can be overclocked, but it will eventually reach a limit. Faster
memory can be installed, but the cost may not be worth it. The memory clock
can be set to a lower ratio (with some motherboards) to allow higher clock
speeds, but there is a performance penalty.

How you overclock depends on the specifics of your system, how much patience
you have, and much attention you pay to details.

A general approach:

* Download and install MotherBoard Monitor 5 (free) at
http://mbm.livewiredev.com/ . This will allow you to monitor and
record the CPU speeds, fan speeds, CPU temperature (and perhaps motherboard,
memory, and other temperatures, and voltages.)

* Download and install SiSoft Sandra (free) at
http://www.sisoftware.net/ . This program is a collection of
information gathering applets for your system. It also has low level tests
of performance, as well as stress tests (necessary to establish proper
operation when the CPU is operating at full capacity. I find version 2004
more useful than 2005, but 2004 is hard to find now.

* Use MotherBoard Monitor 4 and SiSoft Sandra because the vast majority of
the people who use this forum also use these applications

* Read the manual carefully.

* Clean the heatsink fins, and fans of all dust, grease, and dirt.

* Write down the settings in the BIOS.

* Write down the temperature and voltage information from SiSoft Sandra.

* Check the voltages reported by MotherBoard Monitor 5 for you system. If
any are outside the specifications this may affect the operation of your
system, especially if it is overclocked. Also check the total rated output
of your power supply, if it is marginal, overclocking (since more power is
required) may also be marginal.

* Steps for overclocking your Intel CPU (only after completing the above
recommendations):

#0. The standard setup for PCI bus and AGP bus speeds are fractions of
the clock speed. Make sure the PCI/AGP Bus speeds are instead locked at 33
MHz/67 MHz; if the PCI bus speed is more than 36 MHz corruption of data on
your hard drives can occur.

#1. Increase the clock speed by 5%.

#2. Reboot and check for operation.

#3. If #2 is successful, repeat #1.

#4. If #2 is not successful, raise the CPU core voltage by 0.05 volts
(in NO case raise this voltage to more than a total of 15%, doing so may
instantly destroy your CPU; when the core voltage reaches this limit go to
#6.)

#5. Go to #2.

#6. You have reached the limit of overclocking without changing other
factors which may include CPU cooling, System cooling, memory settings.
Installing memory capable of higher clock speeds may help. On the other
hand, some of these changes may be expensive, and not worth the money for
the possible performance increase.


* After reaching the highest speed, check operation under full CPU load (use
SiSoft Sandra burn-in, other burn-in programs, or intense action 3D
accelerated first-person shooter games.) If the system is not stable under
heavy load, try reducing the clock speed and/or CPU core voltage (higher
voltage means higher operating temperatures.)

* Check the installation of the CPU heatsink; new heatsink compound may help
CPU cooling.

* A better than stock heatsink/fan may aid overclocking.

* Improved system cooling may aid overclocking.

* Exotic cooling of the CPU to room temperature or below can significantly
increase top speeds (or not, depending on the individual CPU speed, memory
quality, and motherboard.)

WARNINGS!!!
* Increasing the CPU voltage above 15% over specifications is likely to
INSTANTLY destroy the CPU
* There is always a chance that when you start fooling around inside the
system case of your computer that you may cause damage (the butterfinger
factor.)

You can find a LOT of additional information on the Internet, including the
speeds that others overclockers have reached with your model CPU. One
question you must ask yourself is WHY you wish to overclock; I can think of
three reasons:

#1. Higher performance at little or no expense with your present
system.

#2. Just because you can, and enjoy experimenting

#3. Bragging rights - the highest possible speeds (which is going to
require a LOT more money.

Don't let this long list intimidate you; just go along step by step.

IIRC, the P133 was the end of the S7 (66mhz fsb) and above that was the SS7
(100mhz fsb). It has been awhile, but I did go from a P90 to a 133 and I do
believe that was the max for my S7 MB. Many OEMs in those days did use 'off
the shelf' type MBs, so there just may be a jumper to raise the multiplier
like you said. The tough thing would be getting any information about just
what MB Gateway used. I think AMD had 66mhz processors that may have gone a
bit higher. My memory is junk, so the info here just may be too..........

 >> Stay informed about: overclocking my hunkajunk 

thanks so much phil. so when i change the jumper connections and boot
it up, i can access the bios settings from the boot screen like i
usually do?

p.s.--i know how to build a computer, i just dont have the money to.
 >> Stay informed about: overclocking my hunkajunk 

FrontSide Bus speeds of 100 MHz did not appear until the Pentium II 350 MHz.
The chipsets supporting 100 MHz FSB were not available until the Pentium II.

All Pentium Classic and Pentium MMX were designed for a 50, 60, or 66 MHz
FSB. The Pentium 60 and 66 ran VERY hot, and really had no overclocking
potential ( though that is a guess, as I've never seen a report of anyone
even trying.) My first Pentium was a Pentium 90 (60 MHz X 1.5). It would
overclock to 66 MHz X 1.5 = 100 MHz, 60 X 2 = 120 MHz, and 50 X 1.5 = 125
MHz.) Pentium 133 MHz and up would reach 200 - 233 MHz.

The earlier Pentium II CPUs were not multiplier locked, and could be
overclocked by increasing the multiplier (Pentium II 233 MHz with a
multiplier set to X 4.5 = 300 MHz) or by forcing the FSB to 100 MHz and
reducing the multiplier (Pentium II 233 MHz with a 100 MHz FSB and a
multiplier of X3 = 300 MHz.)

My thought is that the original poster will have to scrutinize the
motherboard looking for a silk-screened label and/or writing down the
original settings and making guesses. That, and possibly purchasing a
used/pulled Pentium 200 or 200 MMX.

By the way, it is getting harder and harder to find reference sheets on
older CPUs at the Intel site; I could not find anything but a loop when
looking for the Pentium Classic/MMX. I'm going to download and save data
sheets on all the older CPU lines.

Changing the jumper setting for the clock multiplier should have no effect
on accessing the BIOS.
BUT if the CPU will not operate correctly at the higher speed, you may not
get any display at all, or the BIOS display may freeze. In that case, just
turn off the system and reset the jumper to its original location. Most
likely when you raise the multiplier by 0.5 the system should boot ok, and
you have a chance with raising it by 1. After you get a successful boot,
then the next test is for Windows to load completely. The final test is how
well the system runs under a heavy load (first person shooter, for example.)

Questions -

How did you identify the correct jumper, and what settings are available?

Is there a jumper for CPU voltage?

Good luck.

The P60 and P66 were 5V vcore CPUs, that was the primary reason for the heat
IIRC. All other (pre-MMX) Pentiums ran at 3.3V vcore standard.

Thanks Phil. Going back 8-10yrs is rough.......... I just read this
morning about Intel releasing their Core-2 Quad by early next year.........
Amazing where we have gone from the mid 90s.

It may. Overclocking is not cut and dried. Some chunks of silicon do better
than others, even when the stepping of the processor is the same. Some of
the best results were with MBs that could do 100/133mhz fsb and running a
100mhz processor at 133+. That was a bit later than yours and it has been
awhile for most of us since we OC'd the earlier Pentium and Pentium Pros.
Some of us have aged a bit, as you saw with the correction to my
post....... Keep us informed.

Not quite. *All* later Intel Pentium CPUs ran on a 66MHz FSB/Socket 7 as
standard.

The SS7/100MHz board was only needed to support (much) later AMD CPUs in the
400MHz and upwards range. Intel were well into Slot 1 and the Pentium II by
then.

Please keep us posted. Your attempt brings back memories for some of us.
We'll be interested to see how you do.

If you get a 200 MHz clock speed Pentium, you will not be able to overclock
very much, but then you won't need to B^)

As 'misfit' posted, the Pentium MMX CPUs require a split voltage supply -
both 3.3 volts and 2.8 volts. Your motherboard may not provide the second
voltage, and it may be difficult to discover if it does.
