The number one factor that determines what processor you can install is the socket type of your motherboard. AMD and Intel use different sockets, and both manufacturers use multiple socket types depending on the processor.
Your motherboard's documentation will provide you the necessary socket information. Not all processors from the same manufacturer use the same socket. You cannot upgrade the processor on most modern laptops. Older laptops Pre ish may be upgradable though. Use the CPU-Z program to determine your socket type. CPU-Z is a freeware utility that can determine what kind of hardware you have installed.
This is the easiest program to use to find your motherboard socket type. Download and install CPU-Z from www. Run CPU-Z.
Click the "CPU" tab and note what is displayed in the "Package" field. Visually inspect the motherboard if you can't find documentation. Open your computer and find your motherboard's model number to look it up online.
Click here for detailed instructions on visually inspecting your motherboard. Take your old processor to a computer store if you can't identify it. If you still cannot identify the socket type, remove your old processor from the motherboard and take it to a computer specialty store.
One of the technicians should be able to tell you what socket type it is, and may be able to make recommendations on what processors would be good replacements.
Consider purchasing a new motherboard if you want to upgrade. If you're trying to upgrade an older computer with a newer processor, there's a pretty good chance that the sockets won't match.
As time goes on, getting a new processor that fits an older motherboard becomes more and more difficult. Purchasing a new motherboard along with your new processor will make things a lot easier. Note: If you're upgrading your motherboard, you may also need to upgrade your RAM , as old RAM is often incompatible with new motherboards.
Part 2. Open up your computer case. In order to access your processor, you'll need to open your case. Shut down the computer and unplug all of the cables. Set the computer on its side with the back connectors resting closest to the table. Remove the side panel using a Phillips screwdriver or the thumbscrews.
Click here for more detailed instructions on opening your case. Ground yourself. Make sure you are properly grounded before working inside your computer. Attach an antistatic wriststrap to the bare metal of your computer case, or touch a metal water tap.
Locate the CPU cooler. Virtually all processors will have a CPU cooler installed on top. This is typically a metal heatsink with a fan attached. You will need to remove this in order to access the processor. Remove any cables or components blocking access.
The inside of a computer can be a pretty crowded space, and there may be cables or components that are blocking part or all of the CPU cooler. Detach anything you need to in order to access it, but make sure you remember where everything was plugged in.
Remove the CPU cooler. Unplug the cooler from the motherboard and then detach it. Most stock coolers have four prongs that can be undone with your fingers or a flathead screwdriver. Some CPU coolers have a bracket on the back of the motherboard that must be removed first. After popping the cooler off of the motherboard, it will likely still be attached to the processor because of the thermal paste.
Gently twist the heat sink back and forth until it comes free of the processor. If you're going to be reusing the CPU cooler on the new processor, wipe off the excess thermal paste from the bottom of the cooler with rubbing alcohol. Detach the lever on the side of the CPU socket cover.
This will pop the socket cover up and allow you to remove the CPU. Gently lift the CPU straight out. You may have to angle the processor a little bit to get it out from under the socket cover, but make sure you are clear of the pins before doing so.
If you want to save your old CPU, make sure to store it in an antistatic bag. Part 3. Install your new motherboard if necessary.
If you are upgrading your motherboard in order to use a new CPU, you'll want to do this first before proceeding. Remove all of the components and cables from your old motherboard, and then remove it from the case. Install the new motherboard in the case, using new standoffs if necessary.
Click here for detailed instructions on installing a new motherboard. Double-check that you are grounded before removing your new processor from the packaging. An electrostatic discharge can easily fry the processor, making it worthless. Touch a metal water tap again if you aren't sure.
Remove the new processor from its protective bag. Be sure to grip it by the edges and avoid touching any pins or contacts. Line up the notches or triangle on the processor with the socket. Depending on the processor and socket you are using, you may have several notches around the edges or a small triangle in one corner. These guides are designed to ensure that you are installing your CPU in the correct position. Gently lay the processor into the socket.
After ensuring that you have the processor oriented correctly, gently place the processor directly in the socket. Do not insert it at an angle. You should never need to force the processor into place.
If you apply pressure, you may bend or break the pins, rendering the processor inoperable. Relatch the socket cover. Apply thermal paste to the processor. This helps conduct heat from the processor to the CPU cooler by removing any imperfections on the contact surfaces. Click here for a detailed guide on applying thermal paste. Secure the CPU cooler. This process will vary depending on the type of cooler you are installing. Stock Intel coolers connect to the motherboard using four prongs, while stock AMD coolers are installed at an angle in metal tabs.
This will provide power to the cooler's fan. Plug in or reattach anything you disconnected earlier. Before closing up your computer, make sure everything that you detached in order to reach the CPU has been properly reattached. The new heatsink has the thermal compound pre-applied. This compound is protected by a thin plastic cover, which you must remove before installing the heatsink onto the CPU. Remove the heatsink from the upgrade kit. Remove the plastic cover that protects the thermal compound.
Position the heatsink over the CPU. Allow the captive screws in the heatsink to dangle, and align the screws with the screw holes on the motherboard. To attach the heatsink to the motherboard, alternately tighten the four screws by turning each screw approximately degrees see FIGURE 7.
The captive heatsink screws are spring-loaded. To counteract the springs, you might need to gently press down on the center of the heatsink while tightening the screws. Continue alternately tightening the screws until all four screws are tight. To install the other heatsink, repeat Step 1 through Step 6. To remove the firmware PROM, gently squeeze the extraction tool.
Remove the PROM from the server, and proceed to the next section. The PROM chip has three right-angle corners. The fourth corner, on the beveled edge side of the firmware PROM chip, is trimmed at 45 degrees. One of the outer-edge corners of the PROM socket is trimmed the same way, and the same interior corner of the PROM socket has a semi-circular protrusion.
To install the firmware PROM chip properly, the trimmed corner of the chip must align with the corner of the PROM socket with the semi-circular protrusion. Handle the chip carefully. Avoid touching the metal contacts. Align the trimmed corner of the PROM chip with the keyed corner of the socket. The trimmed corner of the chip, when properly seated in the socket, must align with the socket corner that has the rounded protrusion see FIGURE 9. When properly aligned, place the PROM chip on top of the socket.
Using your finger or thumb, gently push the firmware PROM chip downward into the socket until the top of the chip is flush with the top of the socket. You clear the CMOS by removing the system battery and shorting the battery terminals for 60 seconds. The opposite side of the battery, the negative side, presses against a metal contact point in the base of the battery holder.
When the battery is removed the metal clip and the contact point do not touch. To clear CMOS, you must make the clip and the contact point in the battery holder touch short for a period of 60 seconds.
Press the metal clip on the battery holder inward until it touches shorts the metal contact point in the base of the battery holder see FIGURE You can use your thumb and finger to press squeeze the clip against the contact point. Continue shorting the clip and the contact point for a period of 60 seconds. The two points must touch short for 60 seconds. Install the air duct, and secure it with the air duct retaining screw.
Proceed to the next section, Preparing for Operation. Perform the following procedures to prepare the upgraded server for operation. Inspect the interior of the server, ensuring that all cables are properly routed and all components are properly seated. Retain the kit packaging material, old heatsinks, and old CPUs. Install the server in the rack, and plug in the power cable. Power on the server and insert the Tools and Drivers CD v2. The defaults load, the server reboots, and the Tools and Drivers main menu appears.
Review the contents of the directory, and make note of the name of the s39u version. Where version is the version number of the SP firmware. To update the firmware enter the following command:. The update script verifies the PROM size before starting the update. The following warning message might appear:. The SP update process takes about two minutes to finish. When the firmware update process ends, the server reboots.
Do the following depending upon the type of upgrade you are performing:. The firmware version preflashed onto the upgrade kit PROM chip might not be the latest version. When the server is operational verify the firmware version, and if necessary, update the PROM.
During the update process the following error message appears if you are attempting to update the PROM with the wrong file:. If this message occurs during the update process, update the PROM with the correct file. Proceed to the next section, Returning Parts to Sun Microsystems.
