damage not only the DIMM but the motherboard. You will be charged to
repair failures or damages caused by the use of such products even within
the warranty period. .
Tips
Up to 384 GB (32 GB x 12) can be installed in 2-CPU configuration. Up to 192 GB
(32 GB x 6) can be installed in 1-CPU configuration. No DIMM is factory installed in
standard configuration.

Memory clock
The server supports the memory clock speed of DDR3-800/1066/1333/1600MHz. However, the actual
memory clock speed depends on CPU model and memory configuration.
The memory clocks of all of buses operate at the same clock speed.
