Installing the Memory
Before attempting to install any memory, make sure that the memory you have is compatible with the
motherboard as well as the processor. The D2778 board supports up to six 240-pin 1.5 V
800/1066/1333 MHz DDR3 modules.
Here are a few key points to note before installing memory into your D2778:
● The following memory modules are supported: 512 MB, 1 GB, 2 GB and 4 GB ECC and non-
ECC memory modules. Registered ECC modules are not supported.
● All installed memory will be automatically detected - no need to set any jumpers
● The D2778 supports up to 24 GB of memory
● The triple channel (triples) memory modules of a CPU should be of the same type and the
same capacity.
● Modules with different timing parameters can be installed on different slots within the same
channel, but only timings that support the slowest Module will be applied to all.
To reach maximal performance, plugging the modules in the following sequence:
i
Simultaneous operation of different memory technologies, unbuffered non-ECC and
unbuffered ECC is not possible.
i
The maximum performance will only be achieved if one memory module per memory
channel is inserted. The memory bandwidth will be reduced from the second memory
module in the channel.
