Installing the processor and cooler
The AMD AM2 socket in HP ProLiant ML115 G5 server supports
AMD Opteron 1XXX series, AMD Athlon 4450B and AMD Sempron
LE 1250 processors.
The server has four DIMM slots that support up to 8 GB maximum
system memory (2 GB in each of the four DIMM slots).
The following guidelines must be followed when memory modules
are being added or replaced:
• Use only DDRII 667/800 unbuffered ECC DIMMs in 512 MB, 1
GB or 2 GB configuration.
• Supported DIMM configurations are single DIMM, one pair (two
DIMMs), or two pairs (4 DIMMs). Channel A corresponds to the
1A and 3B slots, while channel B corresponds to the 2A and 4B
slots.
• For optimal 2 DIMMs configuration, populate 1A and 2A slot.
CAUTION: DIMMs can be damaged by improper handling.
Always use an anti-static wrist strap and grounding mat, and
discharge static electricity before touching DIMMs.
CAUTION: If there are ECC errors in the DIMM(s) during the
system start-up and the screen is blank, the system will emit 8
short beeps.
CAUTION: There is an arrow on the side of cooler that
shows you the correct installation.
