6 Processors
R510 can operate in either single-processor or dual-processor mode. However, since the memory controller
is embedded in the processor, when only one processor is installed in the system, it supports 4 DIMMs, with
minimum memory of 1GB and maximum memory of 64GB (based on the 16GB module). When two processors
are installed in the system, it supports 8 DIMMs, min. 2GB and max 128GB (based on the 16GB module).

QPI or Quick Path Interconnect: A point-to-point processor interconnect developed by Intel which is defined using
Gigatranfers per second (GT/s), referring to a number of data transfers or operations.
Turbo: Feature that increases the speed of the processor on demand (from OS) if the CPU is operating below
power/thermal specifications.
HT: Intel Hyper-threading technology.
