Unit Environment and
Operating Conditions
General Unit Operating Guidelines
Keep the computer away from excessive moisture, direct moisture and the extremes of heat
and cold, to ensure that unit is operated within the specified operating range.
Leave a 4 in (10.2 cm) 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.
Temperature Range Operating: 50° to 95° F (10° to 35° C)
Non-operating: -22° to 140° F( -30° to 60° C)
Relative Humidity Operating: 10% to 90% (non-condensing at ambient)
Non-operating: 5% to 95% (non-condensing at ambient)
Maximum Altitude
(unpressurized)
Operating: 10,000 ft (3048 m)
Non-operating: 30,000 ft (9000 m)
NOTE: Operating temperature is de-rated 1.0 deg C per 1000 ft (300 m) to 10,000 ft (3000 m)
above sea level, no direct sustained sunlight. Maximum rate of change is 10 deg C/Hr. The upper
limit may be limited by the type and number of options installed.

DDR SYNCH DRAM NON-ECC MEMORY
The Intel 946GZ Express chipset supports non-ECC DDR2 memory up to PC2-5300 (667-MHz). Memory upgrades are
accomplished by adding single or multiple DIMMs of the same or varied sizes. This chart does not represent all possible
memory configurations.
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.
HP recommends dual-channel symmetric configurations for maximum performance.
For best performance, add the same amount of total memory to each channel and do not mix speeds. For dual-channel
symmetric performance, the total amount of memory in each channel must be equal. If speeds are mixed, speed will default
to the slowest DIMM.
MAXIMUM MEMORY
Supports up to 2-GB of DDR2 SYNCH DRAM. Not all memory configurations possible are represented below.

Integrated Graphics
Media Accelerator 3000
3D/2D Controller Microsoft DirectX® 9 based with support for Pixel Shader 2.0, 4:1
anisotropic filtering, Gaussian texture filtering, shadow maps, volumetric
textures, double-sided stencil buffers, and 4 pixel pipes.
VGA Controller Integrated
Bus Type PCI Express™ x16 (If an external graphics card is installed in a PCI
slot, the internal graphics can be enabled or disabled using the system's
BIOS setup utility. If an external graphics card is installed in the PCI
Express™ slot, the internal graphics cannot be enabled).
RAMDAC Integrated, 400 MHz
Memory Graphics memory is shared with system memory. Graphics memory
usage varies depending on the amount of system memory installed and
system load. 8 MB is pre-allocated for graphics use at system boot time.
Additional memory is allocated for graphics as needed using Intel's
Dynamic Video Memory Technology (DVMT), to provide an optimal
balance between graphics and system memory use.
System memory equal or greater than 512 MB
8 MB pre-allocated + 248 MB DVMT = max frame buffer of 256 MB
Controller Clock Speed 400 MHz
Overlay Planes Single overlay support with 5x3 filtering
Maximum Color Depth 32 bits/pixel
Maximum Vertical
Refresh Rate
85 Hz at up to 1920x1440, 85 Hz at 2048x1536. Varies with mode and
configuration. See table below.
Multi-display Support Support for one CRT via the motherboard's VGA connector. Support for
an additional DVI-D display via the optional DVI ADD2 card. Dual
independent displays and dual synchronous (Twin or Clone mode)
displays are supported.
Graphics/Video API
Support
Microsoft DirectX®9, DirectXVA®, VMR9, GDI/GDI+; OpenGL® 1.4.

Modes listed are supported with a single active display. The supported mode list for multiple active displays is a subset of
this list. Not all modes will support video playback and some supported modes may use software MC (motion compensation)
rather than hardware MC. Not all modes will support 3D acceleration depending on the system configuration (e.g., resolution
selected, size of frame buffer, number of installed memory modules, etc.).
NOTE: Other resolutions and refresh rates may be selectable but are not recommended.
