Technical Specifications – Hard Disk and Solid State Storage
Worldwide — Version 1.8— May 22, 2014
Introduction:
HP Serial Advanced Technology Attachment (SATA) Hard Drives maximize the performance of HP Business PCs by providing the
technologies to meet your increasing storage demands with high-capacity drives offering superior reliability and performance.
SATA provides faster data transfer speeds, better system cooling airflow, more bandwidth, more headroom for speed increases in
future generations and better data integrity. A next-generation technology, the SATA interface connects hard drives to the PC
platform enabling easy aggregation of multiple hard drives into a single PC. This offers you the additional benefits of dedicated
bandwidth, the ability to more easily identify device failures and scalability. The HP ProDesk 490 G2 Series Business PC supports
the latest SATA 6.0Gb/s specification.
SMART IV Technology
Self Monitoring Analysis and Reporting Technology (SMART) hard drive technology allows hard drives to monitor their own health
and to raise flags if imminent failures are predicted. If the drive determines that a failure is imminent, the SMART hard drive
technology enables the intelligent manageability or management software to generate a fault alert. While the current versions of
SMART hard drives do a good job monitoring the data on the hard drive media, the ever increasing emphasis on reliability and
quality has promoted HP to implement SMART IV technology which constantly checks that the data flow from host interface to
media and media to host interface is not compromised. This is accomplished by inserting a 2 byte parity code into every 512 byte
block in the data path of the hard drive's Cache RAM. This unique parity checking performed by HP's SMART IV technology hard
drives, allows for more complete error detection coverage encompassing the entire data path between the host and the hard drive.
Smart IV is also known as IOEDC: I/O Error Detection Code.
Native Command Queuing
NCQ or Native Command Queuing is a SATA protocol extension that allows the hard drive to have several write or read commands
outstanding at the same time. In contrast, normal non-queued operation requires each command to be completed before the next
command is issued by the host system. Queuing allows the drive to complete the commands in the order that allows for best
overall throughput. It also involves an advanced method of transferring data to or from the host, called First Party Direct Memory
Access (FPDMA), which allows the hard drive and the host controller to manage the data transfers for multiple outstanding
commands, without involving the host processor. NCQ can contribute to better performance but the results are dependent on
many factors, including the access patterns of the various applications and operating system functions that are initiating drive
accesses. Enabling NCQ features in the hard drive requires AHCI support from the host system BIOS, controller, and driver. AHCI
support is typically implemented in RAID configurations.
Note: GB = 1 billion bytes. Actual available capacity is less.

Technical Specifications – Memory
Worldwide — Version 1.8— May 22, 2014
System Memory Support
The HP ProDesk 490 G2 Business PC supports the 4th generation Intel® Core™ processor family. Based on a new PC microarchitecture, the processor is designed for a two-chip platform consisting of a processor and Platform Controller Hub (PCH). Unlike
previous generations, the 4th generation Intel® Core™ processor includes an Integrated Memory Controller (IMC). The IMC supports
DDR3/DDR3L protocols with two independent, 64-bit wide channels each accessing one or two DIMMs.
Two channels of non-ECC DDR3/DDR3Lunbuffered dual in-line memory modules (UDIMM) or DDR3/DDR3L unbuffered
small outline dual in-line memory modules (SO-DIMM) with a maximum of two DIMMs per channel
Single-channel and dual-channel memory organization modes
Data burst length of eight for all memory organization modes
Memory data transfer rates of up to 1600 MT/s; actual supported data transfer rate determined by the configured
processor.
64-bit wide channels
DDR3/DDR3L system memory I/O voltage of 1.5V
Theoretical maximum memory bandwidth of:
o 21.3 GB/s in dual-channel mode assuming 1333 MT/s
o 25.6 GB/s in dual-channel mode assuming 1600 MT/s
Platform Memory Support
Microtower (MT) platforms support up to four (4) industry-standard DDR3-SDRAM DIMMs.
CAUTION: You must shut down the computer and disconnect the power cord before adding or removing memory modules.
Regardless of the power-on state, voltage is always supplied to the memory modules as long as the computer is plugged in to an
active AC outlet. Adding or removing memory modules while voltage is present may cause irreparable damage to the memory
modules or system board.
NOTE: For systems configured with more than 3 GB of memory and a 32-bit operating system, all memory may not be available
due to system resource requirements. Addressing memory above 4 GB requires a 64-bit operating system.

is operated within the specified operating range.
Leave a 10.2 cm (4 in) clearance on all vented sides of the computer to permit the required airflow.
Never restrict airflow into the computer by blocking any vents or air intakes.
Do not stack computers on top of each other or place computers so near each other that they are subject to each other's
re-circulated or preheated air.
Occasionally clean the air vents on the front, back, and any other vented side of the computer. Lint, dust and other
foreign matter can block the vents and limit the airflow.
If the computer is to be operated within a separate enclosure, intake and exhaust ventilation must be provided on the
enclosure, and the same operating guidelines listed above will still apply.

of the hard drive for physical faults and then reports any faults to the user
Running independently of the operating system, it can be accessed through a
Windows-based diagnostics utility or through the computer's setup procedure. It
produces an evaluation on whether the hard drive is the source of the problem and
needs to be replaced
The system expands on the Self-Monitoring, Analysis, and Reporting Technology
(SMART), a continuously running systems diagnostic that alerts the user to certain
types of failures
SMART Technology (Self-Monitoring,
Analysis and Reporting Technology)
SMART I - Drive Failure Prediction
SMART II - Off-Line Data Collection
SMART III - Off-Line Read Scanning with
Defect Reallocation
SMART IV - End-to-End CRC for hard
drives
Allows hard drives to monitor their own health and to raise flags if imminent failures
were predicted
Predicts failures before they occur. Tracks fault prediction and failure indication
parameters such as re-allocated sector count, spin retry count, calibration retry count
By avoiding actual hard drive failures, SMART hard drives act as "insurance" against
unplanned user downtime and potential data loss from hard drive failure
IOEDC: I/O Error Detection Circuitry
Detects errors in Read/Write buffers on HDD cache RAM
Interface in F10 setup provides confirmation of SMART IV support.
