All DIMMs installed must be the same speed.
BIOS detects the DIMM population and sets the system as follows:
Single-channel mode: DIMMs installed in one channel only.
Dual-channel asymmetric mode: DIMMs installed in both channels but of
unequal capacities per channel.
Dual-channel interleaved mode: DIMMs installed in both channels with
equal channel capacities.
The following table lists some, but not all, possible configurations. For best
performance, HP recommends dual-channel interleaved mode configurations.
