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.

DDR SYNCH DRAM NON-ECC MEMORY
The Intel G33 Express chipset supports non-ECC DDR2 memory up to PC2-6400 (800-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.
STANDARD MEMORY
512-MB, 1-GB or 2-GB DDR2 SYNCH DRAM
OPTIONAL MEMORY UPGRADES
Supports up to 8-GB of DDR2 SYNCH DRAM. Not all memory configurations possible are represented below.
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.

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.
