QuickSpecs
Memory
DDR SYNCH DRAM NON-ECC MEMORY
The Intel G45S Express chipset supports non-ECC DDR3 memory up to PC3-10600 (1333 MHz). However, the chipset runs this memory
at a maximum clock rate of 1066 MHz, or at 800 MHz when processor has 800-MHz FSB. 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
1-GB, 2-GB DDR3 SYNCH DRAM
OPTIONAL MEMORY UPGRADES
Supports up to 8-GB of DDR3 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.
