Maximum Memory*
Supports up to 8-GB of DDR2 SYNCH DRAM. Slot 1 is black and must always be populated. 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.

* The Intel Q33 Express chipset includes a built-in Management Engine (ME), which allocates memory for manageability
functions. Management Engine memory is shared with system memory. If the PC contains a single DIMM, 16 MB of memory
is pre-allocated for it at system startup. If the PC contains two DIMMs, 32 MB of memory is pre-allocated. This memory is
not made available to the operating system, just as pre-allocated video memory is not available.
