Memory
Supports un-buffered non-ECC DDR3 SDRAM
The Intel Q43 Express chipset supports un-buffered non-ECC DDR3 SDRAM (synchronous dynamic random
access memory) of up to 16GB total memory, and at a frequency of up to 1066MHz.
NOTE:
1066MHz system memory frequency of operation requires at least PC3-8500 (DDR3-1066)
memory type for all populated memory modules, and an Intel processor with FSB (front side bus) of at
least 1066MHz.
NOTE:
The Q43 chipset Graphics Memory Controller Hub (GMCH) supports DDR3 memory technology up to
a maximum of 1066 MHz. Therefore, systems configured with PC3-10600 (1333 MHz) memory DIMMs will
operate at 1066 MHz.
System Memory upgrades are accomplished by adding DDR3 SDRAM module(s) to empty DIMM slots on
the System Board.
CAUTION:
Voltage is supplied to the memory modules whenever the computer is connected 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. The computer must be shut down with the AC power removed
(disconnect AC power cord at rear chassis or at AC outlet) prior to adding or removing SDRAM modules.
HP recommends dual-channel symmetric configurations for the best memory performance.
For best performance, add the same amount of total memory to each channel and do not inter-mix
memory module speeds. For dual-channel symmetric performance, the total amount of memory in each
channel must be equal. If memory module speeds are inter-mixed, the memory operating frequency will
default to the slowest speed.

Maximum Memory

Supports up to 16GB of un-buffered non-ECC DDR3 SDRAM.
Slot 1 is black and must always be populated. Not all possible memory configurations are
represented in the table below.
NOTE:
For systems configured with more than 3GB of memory and a 32-bit operating system, all
memory may not be available to the OS due to system resource requirements. Addressing memory
above 4GB requires a 64-bit operating system.
