User manual ACER ALTOS R380 F3

[. . . ] Flexible and robust I/O Qualified to work in any environment, this system has dual 10 Gigabit or Gigabit Ethernet connectors onboard. Users can rest assured the R380 F3 will keep up in any high-performance scenario. [. . . ] NOTE: Support for 16 / 32 / 64 GB DIMMs may vary by regional availability. A CPU must be populated for memory to be read. Memory support and population 10 Altos R380 F3 Specifications Independent mode: • • • • • • • • • Also known as performance mode, each DDR channel is addressed individually via burst lengths of 8 bytes. All CPUs support SECDED ECC with x8 DRAMs. Also known as RAS mode, each pair of channels shares a Write Push Logic unit to enable lockstep. Channels are paired together as a domain. All CPUs support SDDC with x4 or x8 DRAMs. rAS mode that require matching populations. Same slot position across channels must hold the same DIMM type (ranks, banks, rows and column) For mirroring mode, the memory image in channel A is maintained the same as channel C and channel B is maintained the same as channel D. Therefore, the effective size of memory is reduced by one-half. lockstep mode: Memory RAS mode: Intra-Socket Memory Mirroring mode: 11 Altos R380 F3 Specifications • The DIMM configuration in mirrored channels must be identical. Channel A & channel C with identical DIMMs and also channel B & channel D with identical DIMMs. [. . . ] Note: All cards marked (I/O module) indicate the card is inserted in the I/O module connector on the node.
