3 Lift the DIMM straight up and remove it from the unit.
NOTE DIMMs and the DIMM sockets are keyed for proper installation. Be sure these guides line up
when installing a DIMM.
Installing Memory Module
CAUTION HP only ships DIMMs that are electrically and thermally compatible with this product.
Because third-party DIMMs might not be electrically or thermally compatible, they are not supported by
HP.
You must load memory modules in valid configurations:
Load DDR SDRAM as matched pairs. For example, if you place a memory module of 1 GB in slot 1,
you must also insert a 1-GB module in slot 2.
Load the memory module pairs in order of size, from smallest to largest, beginning with memory
module pair A (closest to serial port). For example, if you have 1.5 GB of memory composed of two
256-MB modules and two 512-MB modules, load the 256-MB modules in memory module pair A and
the 512-MB modules in pair B.
Install the DIMM in socket 1 if only installing one DIMM.
Install the first matched DIMM pair in socket set A.
Install subsequent matched DIMM pairs in set B (farthest from serial port).
