SYSTEM AND MEMORY OVERVIEW
Note: Refer to your system owner’s manual for detailed instructions and be
sure to follow all static and safety precautions.
p5+ Models 285, 520, 505, 510, 520
• Memory is installed on a system board that has eight DIMM sockets
• The minimum memory requirement is 1GB (2 x 512MB DIMMs)
• The maximum memory capacity is 32GB (8 x 4GB DIMMs)
• Although memory “features”, or “kits” are available in pairs of
matched DIMMs, it is strongly recommended that memory
configurations consist of groups of matched “quads”—four matched
DIMMs—for best performance.
p5+ Model 550
• Memory is installed on one or two processor cards, each having eight
DIMM sockets
• The minimum memory requirement is 1GB (2 x 512MB DIMMs)
• The maximum memory capacity is 64GB (16 x 4GB DIMMs) with two
processor cards
• Although memory “features”, or “kits” are available in pairs of

MEMORY INSTALLATION
Note: Refer to your system owner’s manual for detailed instructions.
Caution: System parts are sensitive to electrostatic discharge and can be
IntelliStation POWER 285, p5 520/520Q (9131-52A), p5 505/505Q (9115-
505), p5 510/510Q (9110-51A)
Remember that ordering and installing DIMMs in matched quads is preferred
with the first quad being J0A, J2A, J0C and J2C and the second quad being
J0B, J2B, J0D and J2D.

Remember that ordering and installing DIMMs in matched quads is preferred
with the first quad being J0A, J2A, J0C and J2C and the second quad being
J0B, J2B, J0D and J2D.
It is also recommended that each processor card have an equal amount of
memory installed. Balancing memory across the cards improves performance.
