Adding Memory

The motherboard contains sockets for either DIMMs (dual in-line memory modules) or DDR (double data rate) DIMMs, depending on which PC model you have.

To determine which type of memory module your PC uses, go to the HP Web site by typing http://www.hp.com into your Web browser address box and pressing Enter on your keyboard. Click the support link. Search for your PC model number, and then search for upgrading memory to find out your system configuration and memory requirements.

The motherboard contains 168-pin DIMM sockets or 184-pin DDR DIMM sockets. The exact number of sockets depends on which model you have.

DIMMs

DIMMs must be 168-pin unbuffered SDRAM (synchronous dynamic random access memory), compliant with the Intel® PC SDRAM Unbuffered DIMM Specification. The PC comes with one or more memory modules, but you can replace existing memory modules with higher capacity ones. You can install 64-MB, 128-MB, 256-MB, or 512-MB memory modules in the PC.

DDR DIMMs

DDR DIMMs must be 184-pin unbuffered DDR SDRAM. The PC comes with one or more memory modules, but you can replace existing memory modules with higher capacity ones. You can install 64-MB, 128-MB, 256-MB, or 512-MB memory modules in the PC.
