the workstation and unplug the power cord from the AC power outlet. Wait until all LEDs on the system
board turn off before removing or installing memory.

DIMM Installation Guidelines
The HP workstation c8000 has eight memory DIMM slots organized as four a/b pairs: 0a and 0b,
1a and 1b, 2a and 2b, 3a and 3b.
The DIMM in each
DIMMs match if they have the same HP part number. (Two empty slots also match.)
For maximum system performance, install DIMMs so that the even pairs match the odd
pairs: 0a and 0b match 1a and 1b; 2a and 2b match 3a and 3b.
Matched pairs should be loaded in this order:
1 slots 0A and 0B
2 slots 1A and 1B
3 slots 2A and 2B
4 slots 3A and 3B
