Memory

Dell Precision™ Workstation 350 User's Guide


CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the System Information Guide.

You can increase your computer memory by installing memory modules on the system board. For information on the type of memory supported by your computer, look under "Memory" in "Specifications."

Memory Installation Guidelines

  • Before you install new memory modules, download the most recent BIOS for your computer from the Dell Support website at support.dell.com.

NOTICE: You can only place a CRIMM in memory module connectors 3 and 4. To locate the connectors, see "System Board Components."
  • Each memory socket on the system board must be occupied by either a RIMM or a CRIMM.

NOTICE: If you remove your original memory modules from the computer during a memory upgrade, keep them separate from any new modules that you may have, even if you purchased the new modules from Dell. You must install your original memory modules in pairs either in connectors RIMM1 and RIMM 2 or RIMM 3 and RIMM4. Do not pair one original memory module with one new memory module. Otherwise, your computer may not start properly.
  • Memory sockets must be upgraded in matched pairs. In other words, two sockets in a pair must contain modules of identical capacity with the same number of components and the same speed. To locate the memory sockets on the system board, see "System Board Components."

Memory Module Label

  • Mixed pairs of ECC and non-ECC modules all function as non-ECC.

  • Mixed pairs of PC1066 and PC800 modules all function as PC800.

  • Be sure to install a RIMM in socket 1 first (closest to the processor) before installing modules in the other sockets.

Before You Remove or Install a Memory Module

  1. Shut down the computer through the Start menu.

  2. Ensure that your computer and attached devices are turned off. If your computer and attached devices did not automatically turn off when you shut down your computer, turn them off now.

NOTICE: To disconnect a network cable, first unplug the cable from your computer and then unplug it from the network wall jack.
  1. Disconnect any telephone or telecommunication lines from the computer.

  2. Disconnect your computer and all attached devices from electrical outlets, and then press the power button to ground the system board.

  3. If you have installed a padlock through the padlock ring on the back panel, remove the padlock.

CAUTION: To guard against electrical shock, always unplug your computer from the electrical outlet before opening the cover.
NOTICE: Before touching anything inside your computer, ground yourself by touching an unpainted metal surface, such as the metal at the back of the computer. While you work, periodically touch an unpainted metal surface to dissipate any static electricity that could harm internal components.
  1. Open the computer cover.

Removing a Memory Module

  1. Press out the securing clip at each end of the memory module connector.

  2. Grasp the module and pull up.

If the module is difficult to remove, gently ease the module back and forth to remove it from the connector.

  1. Align the notch on the bottom of the module with the crossbar in the connector.

NOTICE: To avoid damage to the memory module, press the module straight down into the socket with equal force applied at each end of the module.
  1. Insert the module straight down into the connector, ensuring that it fits into the vertical guides at each end of the connector. Press firmly on the ends of the module until it snaps into place.

If you insert the module correctly, the securing clips snap into the cutouts at each end of the module.

  1. Close the computer cover.

NOTICE: To connect a network cable, first plug the cable into the network wall jack and then plug it into the computer.
  1. Connect your computer and devices to electrical outlets, and turn them on.

  2. Press <F2> to enter system setup and check the value for System Memory.

The computer should have changed the value of System Memory to reflect the newly installed memory. Verify the new total. If it is correct, skip to step 8.

  1. If the memory total is incorrect, turn off and disconnect your computer and devices from electrical outlets. Open the computer cover and check the installed memory modules to ensure that they are seated properly in their sockets. Then repeat steps 4, 5, and 6.

  2. When the System Memory total is correct, press <Esc> to exit system setup.

  3. Run the Dell Diagnostics to verify that the memory modules are operating properly.
