67 Upgrading the system memory Acer Altos R520 server supports eight DDR2 fully buffered DIMM slots with four FBDIMM memory channels. Each channel can support up to 2 dual ranked DDR2 FBDIMMs. The memory channels are organized in to two branches for support of mirrored memory configuration. Up to 8 FBDIMMs or a maximum memory size of 32 GB physical memory in standard non-mirrored mode and 16 GB physical memory in a mirrored configuration are supported by the server. On the server, a pair of channels becomes a branch where each branch consists of: • Branch 0 • Channel A - DIMMA1 and DIMMA2 • Channel B - DIMMB1 and DIMMB2 • Branch 1 • Channel C - DIMMC1 and DIMMC2 • Channel D - DIMMD1 and DIMMD2

Upgrading the system memory
Acer Altos R520 server supports eight DDR2 fully buffered DIMM slots
with four FBDIMM memory channels. Each channel can support up to 2
dual ranked DDR2 FBDIMMs. The memory channels are organized in to
two branches for support of mirrored memory configuration. Up to 8
FBDIMMs or a maximum memory size of 32 GB physical memory in
standard non-mirrored mode and 16 GB physical memory in a mirrored
configuration are supported by the server.
On the server, a pair of channels becomes a branch where each branch
consists of:
•
Branch 0
•
Channel A - DIMMA1 and DIMMA2
•
Channel B - DIMMB1 and DIMMB2
•
Branch 1
•
Channel C - DIMMC1 and DIMMC2
•
Channel D - DIMMD1 and DIMMD2
