That's what I've been running at for 6 months.
My other i7 rigs run at 3.8, but for some reason, there's one 920 that likes to go higher than the others. You can tweak all of that stuff properly, have the right RAm, yada, yada, but at the end of the day, it all comes down to luck of the draw.
"Did I get the good one out of the batch?"
