Expansion Slot Speed Leds - HP ML530 - ProLiant - 128 MB RAM Setup And Installation Manual

Installing Hardware Options
IMPORTANT: Always pair expansion boards of the same speed on the same bus for optimal
performance. If expansion boards of different speeds are installed on the same bus, the server
operates both boards at the lower frequency, resulting in potential bottlenecks.
Use Figure 3-28 and Table 3-8 to identify the speed for each PCI slot and to help
ensure optimal performance.
