66 Installing System ComponentsInstalling the ProcessorNOTE: When installing only one processor, the processor must be installed in CPU0socket (for the socket location, see Figure 5-3).NOTE: Your system uses an LGA 1366 socket, which is designed for trouble freeinsertion of the CPU. After placing the CPU into the socket, press the lever downand lock in place. If you notice any resistance when inserting the CPU, ensure thatit is aligned correctly.NOTE: After removing the processor, place it in an antistatic container for reuse,return, or temporary storage. Do not touch the bottom of the processor. Touch onlythe side edges of the processor.NOTE: If you are permanently removing the processor, you must install a processorblank and a heat-sink blank to ensure proper system cooling. Adding the blank issimilar to installing a processor.1 If you are upgrading your processors, prior to upgrading your system,download and install the latest system BIOS version fromsupport.dell.com. Follow the instructions included in the file anddownload to install the update on your system.2 Pull the locking lever of the processor socket out and up.3 Unpack the processor if it has not been used previously.If the processor has already been used, remove any thermal grease from thetop of the processor using a lint-free cloth.4 Locate the pin 1 indicator on the system board socket.5 Locate the pin 1 indicator on the top of the processor. See Figure 3-9.The pin 1 indicator is shown as a triangle on the top of the processor.6 Place the processor over the socket with pin 1 aligned with the pin guideon the processor socket.CAUTION: Positioning the processor incorrectly can permanently damage thesystem board or the processor.
