Memory Type
Base Memory 4GB (Removable)
Upgrade Slots 12 Socket(s) per CPU 24 Socket(s) using two CPUs
Maximum Memory 32GB ECC UDIMMs 384GB ECC RDIMMs 768GB LRDIMMs
Maximum Module Size
CPU & Chipset Intel Xeon / Intel C600 Series
Bus Architecture PCI Express; USB
Notes Important: Faster memory will clock down to run at optimal speed and voltage depending on processor model and number of modules installed. This system supports Registered ECC (RDIMM) or Unbuffered ECC (ECC UDIMM) or Load Reduced (LRDIMM) memory. Mixing RDIMM, ECC UDIMM and LRDIMM is not supported within this system. Due to chipset limitations, Unbuffered ECC DIMMs are limited to TWO Channel banks per processor. This system supports either Registered ECC or Unbuffered ECC memory. Mixing Registered ECC and Unbuffered ECC modules is not supported within this system.
