Acer AT350 F2 specifications
RDIMM, maximum two DIMMs per channel is supported.
NOTE: Populate the memory of CPU2 to same as CPU1.
NOTE: support depends on 16GB DIMM availability
Mirroring mode:
•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 at least
•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. The DIMM type, size, manufacturer should be the same.
•Same rule is applied to the CPU2
•3 DIMM per channel is only supported by single rank and dual rank RDIMM.
•For UDIMM and quad rank RDIMM, maximum two DIMMs per channel.
Lockstep mode:
•Channel A and channel B are paired and channel C and channel D are paired in lockstep mode.
•Lockstep mode is the only mode to support x8 SDDC.
•Lockstep channels must be populated identically. Channel A & channel B with identical DIMMs and also channel C &channel D with identical DIMMs. The DIMM type, size, manufacturer should be the same.
•Same rule is applied to the CPU2.
•3 DIMM per channel is only supported by single rank and dual rank RDIMM.
•For UDIMM and quad rank RDIMM, maximum two DIMMs per channel.
Rank Sparing mode:
•An unused spare rank is reserved on each channel. The spare rank is used to copy the contents of a failing rank on the channel to keep a system working when a rank starts to fail. The reserved rank is not able to be used before the other rank fail.
•3 DIMM per channel is only supported by single rank and dual rank RDIMM.
•For UDIMM and quad rank RDIMM, maximum two DIMMs per channel.
•For 1 DIMM per channel configuration, only quad rank RDIMM is supported for rank sparing.
Memory Identification
Generally, there are some memory information printed on the label of DIMM, but different vendor may have different format. For example:
4GB 2Rx4
1. Density
11
