Installing memory
Type 6826, 8317, 8318, and 8319 computers have two connectors for installing dual
inline memory modules (DIMMs) that provide up to a maximum of 2 GB of
system memory.
When installing memory, the following rules apply:
v Use 2.5 V, 184-pin, double data rate synchronous dynamic random access
memory (DDR SDRAM), non-ECC DIMMs.
v Use 128 MB, 256 MB, 512 MB, or 1 GB DIMMs in any combination.
Note: Only DDR SDRAM DIMMs can be used.
To install DIMMs:
1. Access the system board. See “Accessing system board components and drives”
on page 22.
2. Locate the DIMM connectors. See “Identifying parts on the system board” on
page 23.
3. Open the retaining clips.
4. Make sure the notch in the DIMM aligns with the tab on the connector. Push or
insert the memory module straight down into the connector until the retaining
clips close.
5. Slide the CD and diskette drive tray back into position and reconnect any
cables that were disconnected. Insert the holding screw.
Note: Be sure to align the drive tray properly on the drive tray tracks,
otherwise the drive tray will not sit properly, nor will the cover attach
properly.
6. Replace the PCI riser and adapters if it was removed.
