HP Compaq dx7300 Microtower PC Specifications

Product description

The HP Compaq dx7300 Microtower PC is designed for customers desiring the latest Intel technology and maximum upgradeability. This PC is created using industry leading Design for Environment standards. Upgradeable, recyclable and energy efficient.

Product features

One of the following:
  • Intel Celeron D Processors
  • Intel Pentium 4 Processors with Hyper Threading Technology
  • Intel Pentium D Processors
  • Intel Core 2 Duo Processors
Intel® Q965 Express chipset
3.4-GHz, 2x2MB L2 cache, 800-MHz FSB
Supports up to 4-GB of DDR2 SYNCH DRAM. Slot 1 is black and must always be populated.
Memory upgrades are accomplished by adding single or multiple DIMMs of the same or varied sizes. The Intel Q965 Express chipsets support non-ECC DDR2 PC2-5300 (667-MHz) and PC2-6400 (800-MHz) memory.
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.
