| Memory Type | DDR3 DIMM ECC REG PC3-10600 1333MHz, ECC PC3-10600 1333MHz, ECC REG PC3-12800 1600MHz, ECC PC3-12800 1600MHz |
|---|---|
| Base Memory | 0MB (Removable) |
| Upgrade Slots | 8 Socket(s) per CPU 32 Socket(s) Total |
| Maximum Memory | 256GB ECC UDIMM with four processors 1024GB Reg ECC DIMM with four processors 1024GB LRDIMM with four processors |
| Maximum Module Size | 32GB |
| CPU & Chipset | Intel Xeon / Intel C600 Series |
| Bus Architecture | SSD - SATA 2.5-inch 9.5mm; SSD - SATA 3.5-inch; USB 2.0/3.x Type-A |
| Notes | Important: If 4GB is installed, the recognized memory may be reduced to 3.5GB or less (depending on system configuration and memory allocation). Maximum configurations require a 64-bit operating system. This system supports either Registered ECC (RDIMM), ECC Unbuffered (ECC UDIMM) or Load Reduced (LRDIMM) memory.
