Main memory
– Populate modules with higher capacities first.
– Within a channel, populate modules in descending order of capacity.
– If memory modules with different speeds are used, the lowest clock rate
applies for all DIMMs.
Regardless of the mode, all DIMMs will run at the highest common
frequency that is allowed by the SPD Data of the DIMMs and the maximum
speed of the selected configuration.
– Mixing UDIMMs, RDIMMs or LRDIMMs is not allowed.
– Mixing ECC and non-ECC DIMMs is not allowed.
– Mixing of quad-rank DIMMs in one channel and three DIMMs in another
channel (3DPC) on the same CPU is not allowed.
