Rules you need to follow when installing or replacing a DIMM.
•
Slot
:
– When a
data bus daisy chain topology
is used: populate DIMMs
from farthest slot (slot 1) to closest
slot (slot 0) to the processor
on a per-channel basis.
– When a
data bus balanced tee route topology
is used: populate DIMMs
in either slot
on a per-
channel basis.

•
Capacity
:
DIMMs with different capacities (only two different capacities)
can be mixed
, install the one with
the
highest capacity first
.
•
Rank
:
DIMMs with different ranks
can be mixed
, install the one with
the highest rank first
.
•
Frequency
:
DIMMs with different frequencies
can be mixed
in the same channel.
•
Voltage
:
DIMMs with different operating voltage
cannot be mixed
. (The only supported DIMM voltage is 1.2V.)
•
ECC/Non-ECC
:
ECC and non-ECC DIMM
cannot be mixed
. (Non-ECC DIMM is not supported for the server.)
•
DRAM
:
x4 and x8 DRAM based DIMMs
can be mixed
, but
not in the same channel
.
•
Type
:
DIMMs of different base module types
can be mixed
, but
not in the same channel
.
•
Vendor
:
DIMMs from different vendors
can be mixed
in the same channel.
