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.

ÅWARNING: To reduce the risk of personal injury from hot surfaces, allow the internal system components to cool before touching.

ÅWARNING: To reduce the risk of personal injury when replacing or removing DIMMs, allow the module being removed from the DIMM socket sufficient time to cool. DIMM temperatures can reach 212° F (100° C).

ÄCAUTION:the module. When handling a memory module, do not touch any of the contacts. Doing so may damage

ÄCAUTION: Static electricity can damage the electronic components of the workstation or option boards. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a grounded metal object.

ÄCAUTION: 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.
