Internal Components Continued Identifier 8 NIC controller in PCI slot Component 9 SCSI controller in PCI slot (on select models) : AGP slot ; Processor < Power supply 4-11 Installing Additional Memory The workstation comes with at least 64 megabytes of Error Checking and Correcting (ECC ) unregistered, synchronous dynamic random access memory (SDRAM) dual inline memory modules (DIMMs) installed and supports up to 384 MB of memory. The memory sockets on the system board can be populated with 16-, 32-, 64-, or 128-MB DIMMs. For proper system operation, the DIMMs must be industry standard 168-pin, 100-MHz or faster unbuffered SDRAM DIMMs. The SDRAM DIMMs must support CAS Latency 2 or 3 (CL = 2 or CL = 3). They must also contain the mandatory Joint Electronic Device Engineering Council (JEDEC) Serial Presence Detect (SPD) information. DIMMs constructed with x4 SDRAM are not supported; the system will not start using unsupported DIMMs. IMPORTANT: Do not mix registered and unregistered, or ECC and non-ECC SDRAM DIMMs. Otherwise, your system will not function properly. CAUTION: Your DIMM sockets have gold metal contacts. When upgrading your memory, it is important to use DIMMs with gold metal contacts (not tin-lead) to prevent corrosion and/or oxidation resulting from having incompatible metals in contact with each other.

Installing Additional Memory
The workstation comes with at least 64 megabytes of Error Checking and
Correcting (ECC ) unregistered, synchronous dynamic random access memory
(SDRAM) dual inline memory modules (DIMMs) installed and supports up to
384 MB of memory. The memory sockets on the system board can be
populated with 16-, 32-, 64-, or 128-MB DIMMs.
For proper system operation, the DIMMs must be industry standard 168-pin,
100-MHz or faster unbuffered SDRAM DIMMs. The SDRAM DIMMs must
support CAS Latency 2 or 3 (CL = 2 or CL = 3). They must also contain the
mandatory Joint Electronic Device Engineering Council (JEDEC) Serial
Presence Detect (SPD) information. DIMMs constructed with x4 SDRAM are
not supported; the system will not start using unsupported DIMMs.
IMPORTANT:
Do not mix registered and unregistered, or ECC and non-ECC
SDRAM DIMMs. Otherwise, your system will not function properly.
CAUTION:
Your DIMM sockets have gold metal contacts. When
upgrading your memory, it is important to use DIMMs with gold
metal contacts (not tin-lead) to prevent corrosion and/or
oxidation resulting from having incompatible metals in contact
with each other.
