NOTE: To use PCIe slots 1 through 4 on the riser, both the processors must be installed.
NOTE: The
The following table provides guidelines for installing expansion cards to ensure proper cooling and mechanical fit. The expansion cards with the highest priority should be installed first using the slot priority indicated. Install all other expansion cards in card priority and slot priority order.
