11.1.2 hp workstation xw6000 Memory
The hp workstation xw6000 system features an Intel E7505 chipset-based system board that
provides dual-channel DDR SDRAM memory support. The four memory module slots accept
industry-standard 184-pin DDR SDRAM DIMMs and are configured with at least two
preinstalled DDR DIMMs (one per channel). To achieve the maximum memory support, you
may be required to replace the preinstalled DDR DIMMs with higher-capacity DDR DIMMs.
The DDR DIMMs must support CAS Latency 2 or 2.5 (CL = 2 or CL = 2.5) and 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.
The Intel E7505 chipset supports both PC1600 and PC2100 DDR DIMMs. These systems are
shipped with PC2100 DDR DIMMs, which provide optimal (266-MHz) performance. If a mix of
PC1600 and PC2100 DDR DIMMs are installed in the computer, the system memory will run at
the lower (200-MHz) speed.
When adding, upgrading, or replacing PC2100 DDR SDRAM memory modules in the hp
workstation xw6000, care must be taken to avoid incorrect pairing of modules in the same
channel. This system does not support mixed DIMM pairing on the same channel.
Å WARNING: To reduce the risk of personal injury from hot surfaces, allow the internal system
components to cool before touching.
WARNING: To reduce the risk of personal injury when replacing or removing DIMMs, allow the
Å
module being removed from the DIMM socket sufficient time to cool. DIMM temperatures can reach
212° F (100° C).
Ä CAUTION: When handling a memory module, do not touch any of the contacts. Doing so may damage
the module.
CAUTION: Static electricity can damage the electronic components of the workstation or option boards.
Ä
Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching
a grounded metal object.
Ä CAUTION: Memory module sockets have gold metal contacts. When upgrading the memory, it is
important to use memory modules with gold metal contacts to prevent corrosion and/or oxidation
resulting from having incompatible metals in contact with each other.
The Intel E7505 chipset-based systems support ECC memory. To utilize ECC functionality all
installed DIMMs must be ECC types. Mixing ECC and non-ECC DIMMs is not supported.
The xw6000 only suports registered (buffered) DDR DIMMs.
The hp workstation xw6000 can be configured with up to eight gigabytes of memory using 2-GB
DIMMs (when available). Windows XP Server, Windows XP Advanced Server, and Red Hat
Linux operating systems support eight gigabytes of memory. The Windows XP Professional and
Windows 2000 operating systems support up to four gigabytes of memory.
