• The server supports one processor. • To avoid damage to a processor or the system board, only H3C authorized or professional server engineers can install, replace, or remove a processor. • The pins in the processor sockets are very fragile and prone to damage. Install a protective cover if a processor socket is empty.
Page 45 Basic DIMM concepts DDR5 DIMMs can perform parity check on addresses and the DDR5 DIMMs cannot protect data from getting lost in case of unexpected system power outage. Rank The number of ranks is usually 1, 2, 4, or 8, generally abbreviated as 1R/SR, 2R, 4R, 8R, or single-rank, dual-rank, quad-rank, or 8-rank.
Page 46 To obtain the memory frequency and maximum memory frequency supported by a specific processor, use the component compatibility lookup tool at http://www.h3c.com/en/home/qr/default.htm?id=66. You can query the memory frequency by selecting Memory Module and query the maximum supported memory frequency by selecting Processor.
