Can anyone tell me how and if I can overclock this cpu? Thanks in
advance.
THIS IS FOR A GATEWAY 166 purchased in early 1998. It may or may not
be similar to yours, and following these directions is AT YOUR OWN
RISK!!! That said, here ya go.
It depends on your motherboard. Look in your manual if you have it
(page 58-59 in the one for several of our 166mz office machines here).
Jumpers JB1 and J21, located between the CPU and memory slots,
determine CPU speed. JB1 sets your clock rate, J21 your bus speed.
These systems have a choice of several clock rates and two bus speeds,
60mz and 66mz. Jumper J21 is ALREADY AT 66, so leave it alone. Jumper
JB1 is on jumpers 3-5 and 4-6 for a 2.5X multiplier (2.5x66mz=166mz).
You need to take the jumper off 3-5 and place it on 1-3. This changes
the multiplier to 3X (3x66=198mz). Reboot and try it. If it works
reliably you may want to go for 233mz, as this MB also supports a 3.5
multiplier. This setting requires you to remove JB1 jumpers from 4-6
and jump 2-4 .
Here is the layout for each setting... (all settings are at 66mz bus
speed)
CPU Speed CPU Clock JB1 J21
=====================================
166mz 2.5 3-5,4-6 1-2
200mz 3.0 1-3,4-6 1-2
233mz 3.5 1-3,2-4 1-2
The 200mz setting has been working flawlessly here on 3 machines since
day 1( almost a year). Never tried 233 as this IS an office after
all!! hehehe
Good luck!
Assuming you have a socket 5 motherboard check this web page out:

I have the same machine oc'd to 200. Look in your motherboard manual for
the jumper settings for the clock multiplier. Set it for a 200MHz chip and
reboot. If its the same exact board that I have, then the jumpers should be
located directly across from your PCI slots and labeled J9C1. Change the C
block to 1-2, 5-6 and the D block to the same.(Just in case you lost your
manual:) Good luck
