Compatible with: HP Workstation Z600 SERIES Z2 ONLY MOTHERBOARD Maximum Memory: 24 GB ECC-UDIMM with 2 CPUs 48 GB RDIMM with 2
CPUs
Expansion: 3 Sockets (1 bank of 3) per CPU 6 Sockets total MODULES MAY BE INSTALLED ONE AT A TIME; however, for optimum performance install modules across all three memory channels for triple channel memory interleaving. If 4GB is installed, the recognized memory may be reduced to 3.5GB or less (depending on system configuration and memory allocation). A 64-bit operating system is required to utilize more than 4GB of memory. Registered DIMMs on Z600 requires a systemboard with the C2 revision of the Intel 5520 chipset 4GB DDR3-1333 Reg ECC modules come in two versions: 313/4G using x4 and 3138/4G using x8 DRAM. The two parts may be installed in the same system but not within the same memory bank. Use like modules for dual and triple channel operation. This system supports either Registered ECC or Unbuffered ECC memory. Mixing Registered ECC and Unbuffered ECC modules is not supported within this system.
