Acer AB460 F1 - Manual (Page 230)

3 Server Blades: Setup and Installation 210
Memory Support
Each node of a AB2x280 F1 blade module supports up to 128GB/32GB
of ECC Registered/Unbuffered ECC DDR3-1333 SDRAM in eight DIMM
sockets.
Memory Installation
The mainboard of each blade unit must be populated with DIMMs
(Dual In-line Memory Modules) to provide system memory. The DIMMs
should all be of the same size and speed and from the same
manufacturer due to compatibility issues
.
Populating Memory Slots
The mainboard of a AB2x280 F1 blade module has eight memory slots
per node. Both interleaved and non-interleaved memory are
supported, so you may populate any number of DIMM slots.
Populating slots at the same time with memory modules of the same
size and of the same type will result in three-channel, interleaved
memory, which is faster than single-channel, non-interleaved memory.
See the following table and Figure 3-106 for details.
