Additional tips
• For applications doing direct bus Peer-to-Peer transfers between cards, load the corresponding cards in slots located
behind the CPU. For instance, load cards in slots 2, 4 and 5.
• For very high bandwidth applications in dual CPU systems, select CPU models with the highest QPI frequency (9.6 GT/s).
• Make sure all I/O cards are loaded in slots that have a PCI-Express Lane Width at least as wide as the card (see Table 3).
• For predictable latencies, try disabling NUMA (Non-Uniform Memory Access) mode (BIOS setup menu -> Advanced ->
Bus Options -> NUMA = Disabled).
• For cards that are latency sensitive, load these cards in CPU slots.
• Ensure Idle Power Savings BIOS setting is set to Normal (BIOS setup menu -> Power -> OS Power Management -> Idle
Power Savings = Normal).
• Use the latest BIOS version available on hp.com.
• Check for updates in the latest performance optimization white papers (link below).
• If a conguration has both a double-wide graphics card and a Thunderbolt™ 2
3
card, move the double-wide graphics
card from slot 2 to slot 5.
