Note
The Intel Xeon processor E7 series supports Hyper-Threading (HT). HT is
recommended and was tested in our configuration. However it is good practice
to test HT with your particular application.

Table 3 represents the minimum, middle, and maximum memory combinations possible for the 4, 8, and 16 GB
memory kits available for the DL980 G7 servers. Memory is installed into cartridges; each cartridge supports a
minimum of 2 DIMMS and a maximum of 8 DIMMS. For best performance, HP recommends the use of dual or quad
rank memory DIMMs.

Note
Max memory depends on the number of processors configured. Four/eight
processor configurations support up to 1TB/2TB of memory, respectively.
However Red Hat Enterprise Linux 5.x only supports up to 1TB of memory. Red
Hat Enterprise Linux 6.x supports the maximum memory configuration of the
DL980 (though official Oracle support for that platform was not announced as of
the initial publication of this document).
