MAX MEMORY: 768gb (24x32gb) MEMORY SLOTS: 24 NON-REMOVABLE BASE MEMORY: 0 INSTALLATION NOTES: Four memory channels per processor (up to 3 DIMMs per channel). By default, all DIMMs run at 1.35V, which yields 1333MHz memory speeds. Changing the BIOS setting to Performance Mode forces the DIMMs to operate at 1.5V and 1600MHz (provided the DIMMs are PC3-12800, the processor model supports 1600MHz operation, and there are less than 3 DIMMs per channel). With 3 DIMMs per channel, memory runs at 1.5V and 1066MHz regardless of the BIOS setting.
