https://docs.oracle.com/cd/E19712-01/820-3318-14/820-3318-14.pdf These systems require 1.5v FB DIMMS FB-DIMM Configuration Guidelines for Sun SPARC Enterprise T5240 Servers When planning FB-DIMM upgrades to Sun SPARC Enterprise T5240 servers, observe the following memory configuration guidelines: ■ The motherboard has 16 slots that support industry-standard FB-DIMMs. ■ Use only 1.5-volt FB-DIMMs in SPARC Enterprise T5140 and T5240 servers. ■ Sun SPARC Enterprise T5240 servers support three FB-DIMM configurations: ■ 8FB-DIMMs (Group 1 in FIGURE: FB-DIMM Configuration on Motherboard (Sun SPARC Enterprise T5240 Servers) on page 101) ■ 12 FB-DIMMs (Groups 1 and 2 in FIGURE: FB-DIMM Configuration on Motherboard (Sun SPARC Enterprise T5240 Servers) on page 101) ■ 16 FB-DIMMs (Groups 1, 2, and 3 in FIGURE: FB-DIMM Configuration on Motherboard (Sun SPARC Enterprise T5240 Servers) on page 101) ■ SPARC Enterprise T5240 servers can be equipped with a memory mezzanine assembly, which provides an additional 16 FB-DIMM slots. ■ All FB-DIMMs within a single CMP branch must have the same capacity. ■ If the System Firmware is at least version 7.1.7.f, the FB-DIMM capacities on different CPUs can be different. ■ When replacing a faulty FB-DIMM, the replacement FB-DIMM must have the same FRU part number as the FB-DIMM being replaced. If you are not able to obtain a replacement FB-DIMM with the same FRU part number, may need to replace all the FB-DIMMs in the branch to ensure that all FB-DIMMs in that branch have the same FRU part number.
