Troubleshooting rx3600 Memory
The memory controller logic in the zx2 chip supports three versions of memory expanders. An eight
DIMM memory carrier provides two memory boards that hold two or four memory DIMMs in both
memory cells 0 and 1. A 24 DIMM memory carrier provides two 12-DIMM memory boards that
hold four, eight, or twelve DIMMs in both memory cells 0 and 1.
All three versions of memory expanders must have their memory DIMMs installed in groups of four,
known as a quad. DIMM quads of different sizes can be installed in any physical rank on all
versions of memory expanders, but they must be grouped by their size.
Both the 24 and 48 slot memory expanders support physical memory ranks with four DIMMs, while
the common 8 slot memory expander’s memory cells 0 and 1 each support physical ranks with
two DIMMs. In the 8 slot memory expander, however, the logical quad of four DIMMs includes
ranks from both sides 0 and 1 running in lock step with each other.
Memory DIMM Load Order
For a minimally loaded server, four equal-size memory DIMMs must be installed in slots 0A, 0B,
0C, and 0D on the same side of the 24/48 slot memory expander; and in the 0A and 0B slots
on both 0 and 1 sides of the 8 slot memory expander.
The first quad of DIMMs are always loaded into rank 0’s slots for side 0 then in the rank 0’s slots
for side 1. The next quad of DIMMs are loaded into rank 1’s slots for side 0, then for side 1, and
so on, until all ranks slots for both sides are full.
Best memory subsystem performance result when both memory sides 0 and 1 have the same number
of DIMM quads in them.
Memory Subsystem Behaviors
The zx2 chip in rx3600 servers provides increased reliability of memory DIMMs and memory
carriers.
