Hello Besar --
The Opteron 2378 is a third generation Opteron ("Shanghai").
As such, it will support IBS including the dispatch op sampling
mode for IBS op sampling. This is the preferred IBS op mode since
it produces a regular distribution of op samples and the distribution
reflects the execution frequency of the basic blocks/instructions.
The Opteron 2378 is stepping C2, so yep, it's RevC. Family 10h
processors starting with RevC support the dispatched op sampling mode.
Hope this helps -- pj
