X4170应该配几条内存?

X4170,双C，最低可以配几条内存？三条还是六条？
我知道X4170M2是每个CPU至少要保证三条，如果X4170M2的话，需要配6条内存，那X4170呢？是一样么？

Integrated Memory Controller
Each processor has an integrated memory controller with 3 DDR3 channels and up to 3 DIMM
sots per channel for a total of 9 DIMM slots per processor.
------从字面看，最少6条。 每个CPU3条
