!WARNING:

You must wear an ESD wrist strap when installing or removing hardware components to prevent electrical discharge that can damage the system.

CPU and memory configurations

The minimum memory configuration of the V880 is one CPU/Memory board that has two processors and 4-GB of memory. The V880 computer can be upgraded to a total of four CPU/ Memory boards, with a maximum memory of 16-GB.

The minimum memory configuration of the V890 is one CPU/Memory board that has two processors and 8-GB of memory. The V890 computer can be upgraded to a total of two CPU/ Memory boards, with a maximum memory of 16-GB.

! Important:

The CPUs in all memory boards must match. You cannot, for example, mix a 900 MHz CPU with a 1.2 GHz CPU, or an UltraSPARC III CPU with an UltraSPARC IV CPU.
