Before You Begin 3
TurboChip 233 User’s Guide - Rev. A01 Kingston Technology Company
Before You Begin
The TurboChip installation should take less than 15 minutes to complete.
Before you begin, however, there is one very important point to be aware of.
First, notice the location of pin-1 on the TurboChip upgrade denoted by a white
triangle on the bottom of the unit. This corner of the upgrade must match pin-1
on the processor socket (See figures below). Your Pentium®computer should
be using either a Socket 5 or Socket 7 type processor socket. pin-1 orientation
is standard for both socket types. Take a few moments to read the section below
before beginning the installation process.
Pin-1 Orientation
The location of pin-1 on the TurboChip must be oriented to match pin-1 on the
processor socket. The TurboChip upgrade is keyed to fit only one way into the
CPU socket. If the pins are aligned, the upgrade should easily slide into the
socket. Refer to the figures below for proper orientation:

Installing the TurboChip
The TurboChip 233 processor upgrade is designed to work in Pentium 75, 90,
100, 120, 133, 150, 166, 200, and 233MHz computers. The installation
procedure will differ slightly according to the location of your processor
socket. Follow the steps below to install TurboChip into your computer.
Step 1. Opening the Computer
1. Set the power switch on the system unit to OFF.
2. Set all external power switches OFF (i.e. display, printer, etc.).
3. Disconnect all power cords and cables from the rear of the computer.
4. Remove the cover from your computer as described in your owner’s
manual. Make sure you have room to work. If necessary, place the
computer on a desktop surface that is easily accessible with plenty of
area to work.
Step 2. Locating the CPU
1. Locate the Pentium CPU chip on your system board or CPU
expansion card. The CPU chip will most likely have a large metal
heatsink attached on top (See Figure 4 on the next page to view a
standard heatsink). Note: some system manufacturers also include a
cooling fan on top of the heatsink.
2. Make sure the CPU chip is accessible. If the CPU socket is located
under an expansion card, move any full-length adapter cards to other
expansion slots. If no slots are available, place a half-length card in
the slot nearest the CPU socket so that the CPU socket is
unobstructed. If the CPU socket is located under the floppy drive
(e.g., IBM ValuePoint™), loosen the retaining screws and remove the
drive bay for easier installation.

Step 3. Removing the CPU Chip
1. Remove the Heatsink Retaining Clip: If your CPU has a heatsink
similar to the illustration below, it is most likely secured with a
retaining clip. Before removing the CPU chip from its socket, you
must first unlatch the retaining clip by pressing down on the retaining
clip tab (See Figure 4) then prying one side of the retaining clip
latch using the screwdriver (provided). Try not to touch the
motherboard or any other components near the socket. With the
retaining clip completely removed from the heatsink, you are ready to
remove the CPU chip.
Note: The retaining clip is not needed for the TurboChip upgrade.
2. Unlock the Socket: Socket 7 and Socket 5 ZIF (zero insertion force)
sockets use a side bar lever to lock and unlock the socket. Unlatch the
side lever and lift upward to unlock the processor chip. Once the
socket is in the unlocked position, remove the CPU by grasping the
sides of the chip with your fingers.
Note: you may use the TurboChip’s protective foam packaging to store
your original CPU chip.

Step 4. Orienting the TurboChip
When installing the TurboChip, the orientation of pin-1 (See Figure 1 on page
3) must match pin-1 on the processor socket (See Figures 2 and 3 on page 3).
The orientation of the processor socket will vary depending on the make and
model of your particular computer. Follow the steps below to determine the
correct orientation of TurboChip in your computer.
1. Look at the TurboChip carefully to verify which corner is pin-1.
Refer to Figure 1 on page 3 for help in locating pin-1 on the
TurboChip.
2. With the TurboChip positioned so that the beveled corner on the
upgrade matches the beveled corner on the processor socket, you are
ready to insert TurboChip into the empty CPU socket.
Warning: The processor pins are keyed to fit into the socket one way only. If
the processor upgrade is not installed correctly (pin-1 to pin-1), it may result in
damage to the computer, the processor upgrade, or both. Please orient pin-1 on
the TurboChip upgrade to match pin-1 on your CPU socket. Refer to Figure 5
below.

Step 5. Inserting the TurboChip
To insert the processor upgrade correctly, you need to have the pins on the
TurboChip adapter exactly lined up with the corresponding holes on the CPU
socket.
1. While the socket is unlocked or in the open position, align the pins
on the TurboChip into the holes on the ZIF socket. Place the
TurboChip into the socket without using any force. Apply gentle
pressure, only if needed, to make sure the processor is completely
inserted, but be careful not to press down on the fan unit. Instead,
grasp the sides of the unit for handling.
2. Lower the sidebar to close the socket back to a locked position.
Refer to Figure 6 below.

Kingston Technology Company TurboChip 233 User’s Guide - Rev. A01
Step 6. Plugging in the Power Cable
The TurboChip uses a standard 4-Pin Molex connector which attaches to any
available power connector coming from the computer’s power supply. The
power supply in your computer should have several power connectors available
for adding hard drives, CD-ROMs, and other devices.
Note: The external power cable allows the TurboChip to support both Socket 5
and Socket 7 processor sockets.
Find any available power connector which is not currently in use and attach it
to the 4-Pin male connector from the TurboChip (See Figure 7 below). If no
power connectors are available, the TurboChip also has an in-line female
connector which allows the upgrade to connect into an existing power line.
Simply disconnect an existing power cable. Attach the male connector to the
power source. Then reattach the other end of the cable to the in-line female
connector on the TurboChip cable.

Step 7. Completing the Installation
1. Replace any adapters removed earlier.
2. Depending on the clock speed of your original Pentium®processor,
the external bus speed may be running at 50MHz, 60MHz, or
66MHz. If your computer has a hardware jumper on the system board
to set the external bus speed, set it to 66MHz. If your motherboard is
not set to 66MHz, the TurboChip will not run at optimal
performance. Refer to the table below:
External Bus Speed Clock Multiplier Processing Speed
50MHz 3.5x 165MHz
60MHz 3.5x 210MHz
66MHz 3.5x 233MHz
Table 8: Setting the external bus speed
Note: If your computer does not have a jumper setting for clock
multiplier or voltage levels, the TurboChip upgrade will
automatically set the clock multipler (1X, 1.5X, 2X, etc.) to 3.5X and
regulate the necessary voltage to your system (2.8V or 3.3V).
3. Replace the computer cover, and reconnect any cables that were
removed.
4. Check that your computer starts correctly. It should begin a memory
count and run its POST (Power-On-Self-Test). If it does not boot,
turn to “Appendix B Troubleshooting” in the back of this manual for
help.
Congratulations! The installation is now complete. Because TurboChip
requires no device drivers, there is no software installation to perform. If you
experience any problems, refer to “Appendix B Troubleshooting”. If your
problem is beyond the scope of this manual or you have questions regarding
this product, call Kingston Technical Support at [phone] or toll-free at

Benchmark Test Results
Note: Test results will vary depending on your configuration, make, and model.
The following benchmark tests were performed on an HP®Vectra VL5/100
(100MHz Pentium) and a Dell®Dimension™P75 (75MHz Pentium). The
results depend on the external bus speed of the systemboard which usually runs
at either 50, 60, or 66MHz. Some systemboards use a hardware jumper to set
the external bus speed. If your system has a jumper to set the bus speed, set it to
66MHz.
