Main memory operating modes

There are four operating modes for the main memory:

– Independent channel mode (maximum population)

The populated memory of the six channels (A - F) can be used completely

(max. 144 GB).

– Mirrored channel mode (maximum security)

Only the populated memory of the two channels A and D can be used (max.

48 GB). The channels B and E serve as safeguarding against failure. The

memory belonging to the channels B and E contain the mirrored data of the

memory belonging to channel A and D. The channels C and F are not used.

– Performance channel mode (maximum performance)

The populated memory of the six channels (A - F) can be used completely

(max. 144 GB).

– Spare channel mode (large population and large security)

Only the populated memory of the four channels A, B, D and E can be used

(max. 96 GB). The channels C and F serve as safeguarding against failure.

Spare channel mode is only supported by Intel

processor series.

Depending on the mode of operation there are different population
