<strong>HP</strong> <strong>Compaq</strong> <strong>dc7700</strong> <strong>Business</strong> <strong>PC</strong><br />
Standard Features and Configurable Components<br />
Memory<br />
DDR2 SYNCH DRAM NON-ECC MEMORY<br />
Memory upgrades are accomplished by adding single or multiple DIMMs of the same or varied sizes.<br />
This chart does not represent all possible memory configurations. The Intel Q965 Express chipsets<br />
support non-ECC DDR2 <strong>PC</strong>2-5300 (667-MHz) and <strong>PC</strong>2-6400 (800-MHz) memory.<br />
CAUTION: You must shut down the computer and disconnect the power cord before adding or<br />
removing memory modules. Regardless of the power-on state, voltage is always supplied to the memory<br />
modules as long as the computer is plugged in to an active AC outlet. Adding or removing memory<br />
modules while voltage is present may cause irreparable damage to the memory modules or system<br />
board.<br />
<strong>HP</strong> recommends dual-channel symmetric configurations for maximum performance.<br />
For best performance, add the same amount of total memory to each channel and do not mix speeds.<br />
For dual-channel symmetric performance, the total amount of memory in each channel must be equal. If<br />
speeds are mixed, speed will default to the slowest DIMM.<br />
Ultra-slim Desktop<br />
Maximum Memory*<br />
Supports up to 3-GB of DDR2 SYNCH DRAM. Slot 1 is black and must always be populated. Not all<br />
memory configurations possible are represented below.<br />

*NOTE: The Intel Q965 Express chipset includes a built-in Management Engine (ME), which allocates memory for manageability<br />
functions. Management Engine memory is shared with system memory. If the <strong>PC</strong> contains a single DIMM, 8 MB of memory is preallocated<br />
for it at system startup. If the <strong>PC</strong> contains two DIMMs, 16 MB of memory is pre-allocated. This memory is not made<br />
available to the operating system, just as pre-allocated video memory is not available.<br />
Small Form Factor and Convertible Minitower<br />
Maximum Memory*<br />
Supports up to 4-GB of DDR2 SYNCH DRAM. Slot 1 is black and must always be populated. Not all<br />
memory configurations possible are represented below.<br />
NOTE: Above 3-GB, all memory may not be available due to system resource requirements.<br />
