Power cords
Two power cords are required.
The Power 750 requires
System memory
•A minimum 8 GB or two DIMMs of memory is required on the Power 750 system.
•Eight memory DIMM slots are on a processor card. The maximum system memory with one processor card is 128 GB. The maximum system memory is 512 GB with four processor cards.
•Different system memory feature numbers may not be mixed on the same processor card. However, a system with more than one processor card may used different memory feature numbers on the same system.
•Memory must be installed in groups of one feature (two DIMMs), two features (four DIMMs), or four features (eight DIMMs) per processor card. Installation of three features (six DIMMs) is not permitted.
•It is generally recommended that memory be installed evenly across all processor cards in the system. Balancing memory across the installed processor cards allows memory access in a consistent manner and typically results in the best possible performance for your configuration. However, balancing memory fairly evenly across multiple processor cards, compared to balancing memory exactly evenly typically has a very small performance difference.
Plans for future memory upgrades should be taken into account when deciding which memory feature size to use at the time of initial system order.
