* Not all Windows Vista features are available for use on all Windows Vista Capable PCs. All Windows Vista Capable PCs will run
the core experiences of Windows Vista, such as innovations in organizing and finding information, security, and reliability. Some
features available in premium editions of Windows Vista -- like the new Windows Aero™ user interface -- require advanced or
additional hardware. Check http://www.windowsvista.com/getready for details.
** Hardware RAID is not supported on Linux systems. The Linux kernel, with built-in software RAID, provides excellent, functionality
and performance. It is a good alternative to hardware-based RAID. Please visit
http://h20000.www2.hp.com/bc/docs/support/SupportManual/c00060684/c00060684.pdf for RAID capabilities with Linux.

Only unbuffered DDR2 DIMMs (ECC unbuffered or non-ECC) are supported and must be x8 or x16 width. Memory upgrades are
accomplished by adding DIMMs of the same or varied sizes.
ECC/Chipkill parameters
ECC/Chipkill parametersECC/Chipkill parameters
ECC/Chipkill parameters
Chipkill on the HP xw4550 functions within these parameters:
The workstation enables Chipkill functionality on paired ECC memory DIMMs only. When a single ECC DIMM is loaded,
standard single bit correct and two bit detect ECC is supported.
Chipkill can detect and correct up to four bit errors if the four bits are in the same symbol. That is, multiple bit errors in bits
0–3 or 4–7 of a byte can be detected and corrected. Multi-bit error that overlap or span symbol boundaries (bits 2–5 or 3–6,
for example) cannot be corrected. For DIMMs that are based on x4 parts, this means that a single DRAM chip can fail and the
system will continue to operate. For x8 and x16 parts, a complete DRAM chip cannot fail, but symbol errors will be corrected
as described. Memory Scrubbing – xw4550 supports Sequential plus Source Correction Scrubbing
Sequential Scrubbing
Sequential ScrubbingSequential Scrubbing
Sequential Scrubbing
In this mode, the scrubber sequentially proceeds through main memory, performing a read-write cycle or a read-
modify-write cycle if a correctable error is found. The scrubber scrubs one cache line on each scrub interval that is
programmable from 40 ns to 84 ms.
Source Correction Scrubbing
Source Correction ScrubbingSource Correction Scrubbing
Source Correction Scrubbing
In this mode, the scrubber is directed to scrub any cache line that is the source of any corrected error during normal
accesses. During normal operation when source correction scrubbing is disabled, single-bit errors are corrected on the
fly and the corrected data is passed without updating the source memory location. When source scrubbing is enabled
the scrubber also corrects the source memory location.
Sequential Plus Source Correction Scrubbing
Sequential Plus Source Correction ScrubbingSequential Plus Source Correction Scrubbing
Sequential Plus Source Correction Scrubbing
When both sequential and source correction scrubbing are enabled, the scrubber sequentially proceeds through main
memory. If a correctable error is detected during normal operation, the scrubber is redirected to the location of the
error, and after it corrects that location in main memory it resumes sequential scrubbing at the previous location
Memory configuration suggestions
Memory configuration suggestionsMemory configuration suggestions
Memory configuration suggestions
For best performance the total amount and type of memory loaded into Channel 1 and Channel 2 should be the same and should
be loaded in pairs (two 512 MB DIMMs will have better performance than a single 1 GB DIMM). Match pairs by size and type. If
these guidelines are not followed, your computer may not see all the RAM installed and may run the memory controller in a lower
performance mode.
