CPU Rev C1?

I just picked up a yorkshire q9550 with a Rev C1 designation. Many extol the
virtues of E0, presumably for OC'ing. Could someone explain the difference?
I don't care too much about OC'ing (although I might dabble...), but I'd be
interested in knowing the differences between the two and if this Rev (C1)
is inferior.

TIA,
Kim

The additional difference on E0 is:

http://processorfinder.intel.com/details.aspx?sSpec=SLB8V

"These parts have Deep Sleep State (C3E) enabled.
These parts have Deeper Sleep State (C4E) enabled."

So a couple more sleep states were added. Both processors have:

"Enhanced Halt State (C1E)"

As for OC experiences, you'd need to find a database and pick through
the results. Some enthusiast sites have overclocking results, which
you can look at. hwbot.org has a lot of results, but I don't know if
it has enough details to make a selection (site is down right now).
xtremesystems.org forums is another place to look.

Also, the binning of the processors, changes with time, and some
processors that have good early results (when the part starts shipping),
become worse as the bins tighten up.

In this thread, they mention the amount of Vcore it is safe to use.
If you go over 1.4V, the thing may not last too long. Don't get
greedy...
